Brazil's Tsunami Beach and Warning for all of us

Tsunami and Brazil

This week we learned about Tsunami's and read advice from FEMA for before, during and after a Tsunami.  We learned about Volcanic, earthquake and landslides in the ocean that can  cause a Tsunami.  In Brazil there are miles of coast lines and tsunami are a fact of life.

However, when I looked at Brazil I found another form of tsunami and that is Metrological Tsunami.  What is a Meteorological tsunami or meteotsunami you ask?  Well at UNESCO we learn; "... :  Meteorological tsunami (meteotsunami)  "Tsunami-like phenomena generated by meteorological or atmospheric disturbances. These waves can be produced by atmospheric gravity waves, pressure jumps, frontal passages, squalls, gales, typhoons, hurricanes and other atmospheric sources." "Meteotsunamis have the same temporal and spatial scales as tsunami waves and can similarly devastate coastal areas, especially in bays and inlets with strong amplification and well-defined resonant property." (Halas)



 John Halas on CARSCOPES writes:
"Sunbathers, swimmers and casual visitors at the world's longest beach, the Praia do Cassino (literally Casino Beach) in Rio Grande, Brazil, were captured by surprise this past Sunday when a bizarre natural phenomenon known as a Meteorological Tsunami, Meteotsunami or simply, weather-induced tsunami, hit the area.   It caused the sea to swell and spill out a wave that reached all the way up to the parking spots (…or at least where people had parked their rides, possibly too close to the beach), and while humans escaped unscathed, their belongings, including dozens of vehicles, were damaged, as the body of water tossed the cars around on the sand.  According to locals, this isn't the first time that such a tsunami has been observed in the area."

The following picture is one I found that must concern all of us;

 
 
Tsunami Watch
 
 
   This is a Disaster Forecast, not a Hoax
   The British National Press published articles during the
   latter part of 2004 stating that an eminent American vulcanologist, who has
   been an advisor to the United Nations and was in charge of
   tsunami research in Hawaii, has forecast
   that “during the next few decades” there is a probability
   of a tidal wave 120 feet high, hitting the American Eastern seaboard.
   George Pararas-Carayannis, a
   scientist of Greek decent, has stated that this would be caused by a series of
   three volcanoes on La Palma, in the Canary Islands, exploding, propelling a
   piece of faulted material “the size of the Isle of Man”,
   which is in the Irish Sea, into the North Atlantic Ocean.
   This fault is a fact.
   The trouble is compounded when even scientists specialising in the subject cannot agree.
   I have spoken to many people about these newspaper articles and have
   consequently found out and calculated the following information, which I feel I
   MUST pass on, in good faith, even though the news is extremely gloomy to
   millions of people.  There is no way in which any one person can be blamed for
   lack of publicity or lack of action, only Governments. There are not enough
   people who know of this danger to the planet. We are all unqualified in the
   subject of volcanoes and tsunamis, and must put our futures in the hands of
   experts, which include British scientists, to keep information like this
   available.
   “Dr. Simon Day and Bill McGuire of the Benfield Hazard Research Centre at
   University College, London agree and say that the fault is now inherently
   unstable, and that they expect it to crash into the ocean.”
   (Src. Western Morning News)
 
 
 
   Publicised Information
   The wave created would initially be in excess of 1000
   feet (300 meters) high, and would obliterate all life along many thousands of miles of
   shoreline on both sides of the Atlantic Ocean, probably sinking many ships near
   both coastlines of the  Atlantic Ocean.  This wave is expected to be 120 feet (37 meters)
   high when it hits the Boston/New York area.  It is forecast to travel as far
   as 12 miles (19 Kilometers) inland from the American East Coast and  the result will be
   thousands of times worse that the New Orleans flooding, killing hundreds of
   thousands of people and leaving damage which will ruin the American economy for
   decades.
   A BBC Television programme called "10 Things you didn't know about Tsunamis"
   has been broadcast several times on BBC4 and recently (13th March 2008)
   on BBC 2, which is probably a more popular channel, and consequently the programme
   will have more impetus on the public. However, and rather puzzling, the only mention,
   again, is of the consequences to the New York/ Boston area. Possibly a financial
   consideration, I think. However this wave, or series of waves will be 5 hours old when it reaches there.  I have
   analysed, shown below, what would happen in that five hours.
   The Wave...
   ...itself  will travel through water at up to 600 miles (1000 kilometers) per hour and will
   be unseen by sea going vessels, as the wave travels within the upper layers of
   the water.   However, as it approaches the shoreline the wave erupts above the
   water level to the same height as the wave depth, in this case over 100 feet.
   There may also be a series of waves of various sizes.   100/120 feet (37 meters) refers to
   the waves in the quoted New York/ Boston area.   The effect nearer to the event
   will  be MUCH, MUCH worse.
 
 
 
   Further Specific Results
   This wave will spread in a circle, just as a
   stone  thrown into a pond forms concentric ripples.  However THIS TSUNAMI WILL
   MAKE THE INDONESIAN TSUNAMI LOOK JUST LIKE THAT — A RIPPLE.
   This tsunami will, within a few minutes, hit the Northwest African coastline
   with waves which, being closer to the event, will be possibly in excess of 800 feet
   high (240 metres) destroying all coastal cities and all life within many
   miles of the coast. There will be little possibility of any useful warning
   period.  At the same time the Canary Islands and Madeira will suffer the same
   fate.
   Soon after this, and within 2 hours of the event a wave of over 600 feet (180m)
   will sweep North and South devastating  the Azores, Gibraltar and the South
   coast of Spain, Portugal, Senegal, and Guinea.  The wave will continue on into
   the Mediterranean Sea to a similar extent as the below results.
   Within 3 hours a wave, or series of waves, over 400 feet (120 metres) high will
   inundate the whole Bay of Biscay area, and the Southern parts of England,
   Ireland and Wales.  The West African states as far South as Ghana will also be
   seriously affected by now.
   (The earlier estimates for the warning period and wave height for UK has had to
   be updated, unfortunately).
   Four hours after the event Africa will be affected as far South as Gabon, the
   first part of the Americas will be affected (the East coast of Brazil), and the
   wave will have travelled as far North as Iceland and Scandinavia, both by way of
   the Atlantic and the  English Channel and North Sea,  affecting Northern France,
    the South and East of England, including London, Belgium, the Netherlands,
   Northern Germany and Denmark on the way.
   Only after 5 hours does the wave strike the North Eastern States of the United
   States, equally devastating New York, Boston, and all the other coastal areas to
   a distance of 12 miles (20km) from the sea.
   At this stage it might be an idea to contemplate the even     worse disasters
   which would have already occurred in Africa and Europe and try to judge how much
   further the waves will have travelled overland from the coast in these, mainly
   low-lying, countries.
   You can see now, I hope, why I am anxious to get the message passed around the
   World so that SOME effort can be made to save at least SOME of the millions of
   lives which will be lost, and all in a very few short hours.
   This wave, now 5 hours old and still over 35 metres high is now affecting  the
   North coast of Brazil as far West as Trinidad and the Antilles and the African
   coast as far South as Angola.
   Within 7 hours Florida and the remainder of the West Indies will have been
   swamped, and Nicaragua, Mexico, Namibia, Cape Town and South Brazil will be
   badly affected.
 
 
 
   Closer to Home
   The wave hitting the coasts of the United Kingdom will
   possibly be around 400 feet (120 meters) high causing terrible loss of life and will
   literally wreck not only coastal towns and cities, but many inland low-lying
   ones also.
   We may well expect this tidal wave  to hit Devon and Cornwall, and South Wales
   soon after, travelling along the South West  and South coasts of England , the
   entire coast of Wales, North West England and the West coast of Scotland  and
   both coasts of Ireland.  This wave will also travel the full length of the
   English Channel, which will possibly tend to funnel the wave at a near constant
   height, ending up surging into the North Sea, flooding the Low Countries, and
   inundating London.   Unfortunately even the scientists can only speculate as to
   the height of the waves .    The death figures in UK alone will be over a million
   because there is a possibility of the population receiving  ONLY TWO
   AND A HALF HOURS NOTICE OF EVACUATION.   Do you remember how very little notice
   there was when Mount St. Helens finally blew?
   The Overall Picture
   Just imagine  the  overall picture if NO precautionary work is undertaken. The
   damage will be the same, but the loss of life will be very much higher.
   South & West England
   South & West England will suffer worst, with Penzance, Falmouth and Truro,
   Plymouth,  Torquay and
   Exeter,  Weymouth,  Bournemouth and Poole,  Portsmouth  and Southampton ceasing
   to exist. Even cities such as Salisbury and Winchester could
   suffer some flood damage, with enormous loss of life on the way.  Of course,
   this damage will continue further East and North. The East coast will be inundated,
   and all coastal and low-lying areas of Scotland will also be affected.
   On both sides of the English Channel,
   The Bristol Channel and the Irish sea. Bristol and Cardiff, even Gloucester
   and further, will suffer terribly. Many other seaside areas with hills behind
   could POSSIBLY have time to evacuate SOME of their inhabitants to higher land,
   but the majority will not be rescued in time because the  political and civic
   leaders will not have heeded this warning, or acted soon enough.
   What Can Tsunamiwatch Do?
   We, in the United Kingdom, have already contacted the Cabinet Office twice.
   They have passed the buck to DEFRA
   who, by public demand, have issued a pitiful document which shows that the political
   will is not permitting any useful warning systems, other than those available
   at present. These would be entirely inadequate - as time will tell.
   Is This Sufficient Action?
   We think not, which is why we have released this
   document, and are asking for maximum publicity from all areas of the press.
   Our Minimum Target
   is to  get all the warning sirens, used so successfully
   during the War, replaced and supplemented by extra ones so that everyone in low
   lying areas within 30 miles of the sea, lesser distances in areas with higher
   land, can be warned  as effectively as possible.
   Of course the possibility of false alarms must be looked at, but it will surely
   be best to act on every warning than to lose one's life.
   THE POPULATION WILL
   ONLY GET THE ONE CHANCE TO SURVIVE.
   Houston was evacuated, but it took two days.
   Remember that this time you may
   only get TWO AND A HALF HOURS.
   Our Immediate Aim
   is to get assurances from all the MPs representing the West and
   South coast areas, and the town, city, borough and district councils in the
   same areas, to carry out the minimum amount of preparation work, at the minimum
   cost to the country with the biggest end result. We must plan expecting the
   worst scenario. We consider that information spread in the wrong way may
   cause a certain amount of worry and lead to the lowering of coastal property
   prices to the initial detriment of the country as a whole, but THIS CANNOT BE
   HELPED. All Tsunami Watch can do is to ensure
   that the dangers are recognised
   for what they are, INTERNATIONALLY.
   Comments will undoubtedly be made by the cash-strapped Governments about
   sending television and radio announcements out.   Yes, fine, provided there are
   sufficient pre-eruption signs, and Remember,
   that there may be only two and
   a half hours warning-and in the middle of the night. Again, remember Mt. St
   Helens? There was minimal warning when that one blew.
   Important
   In the UK it will be important for each area to have a really
   effective disaster co-ordinator with a senior position in local government to
   examine the local problems for evacuation purposes.    I have been a voluntary
   Area Emergency Planner and I know from my past experience that the existing
   Emergency Planning Officers of most  UK  Councils “have been found more
   important or additional jobs already.” We can see an awareness already
   appearing among various population groups. We would suggest holding a series
   of meetings so that at least a proportion of all coast populations can work out
   for themselves  what to do and where to go, when, not
   if the time comes.
   Transport
   ... of the elderly and infirm will be a priority, but at night bus drivers
   will be at home in bed.  Where roads are going to be congested, traffic going
   INTO an area, such as Portsmouth or Plymouth would be banned, allowing double
   the normal amount of traffic for evacuation purposes, as happened at Houston.
   The Financial Cost
   In the end, and WHEN it  happens,
   the financial cost will be astronomical, IN
   EVERY COUNTRY INVOLVED. In the meantime, if  Governments act quickly and
   quietly loss of life can be minimised. A  much higher loss of life will occur
   if Governments do not take notice, and if some action is not taken soon.
   We would appreciate being informed of any and all useful and meaningful
   decisions made in any areas, so that expert advice can be  centralised and made
   available to as many people as possible.
   PLEASE REMEMBER this disaster may not happen straight away.
   It may be twenty,
   forty, sixty, eighty years ahead, but on the other hand it COULD be next week.
   Very importantly and finally, I have to say that although all of this
   theoretical work was done, as mentioned in the second paragraph, “in good
   faith”, it was started by working on the assumption that the newspaper quote
   was correct. I have only just found out, late in November 2005, from Dr.
   George Pararas-Carayannis himself that he was misquoted.
   He has kindly written “please do not be so hard on yourself and do
   continue with your well intented efforts to properly educate the public
   about disasters and needed preparedness.”
   What I have also learned is the ineffectiveness of government and local
   MPs when you need them. They care little about the fact that well over a
   million British people could possibly have drowned within the loose time-scale
   referred to. My letters to the government have had little impact to date.
   At least we have learned not to rely on government but to try
   talking to local government about early warning systems. (Tsunami Watch)

Brazil and volcano by Linda Potter

 

 

As I started this search I turned first to Wikipedia and found only one volcano listed there.  The following is the information I found there when I put in Brazil and Volcanoes:

This is a list of active and extinct volcanoes found mainly on Wikipedia even though I went through the few listing I found on the web almost all of what I found was linked to Wikipedia.  From what research I found it seems that Brazil has only one active volcano and that is Trindade.  I posted cites that you can view pictures as they would not transfer when I copied and pasted from my windows program.
 

Trindade

600

1968

20°30′50″S 29°19′52″W / 20.514°S 29.331°W / -20.514; -29.331 (Trindade)

Holocene (Wikipedia)

 

BB 

Volcanoes of the world and the number 9 and 41 are the closest to Brazil -- The Trindale hotspot is marked 41 on map (Wikipedia).

The Trindade hotspot is a working hypothesis supposing that the submarine volcanic chain Vitória-Trindade, off the eastern coast of Brazil in the southern Atlantic Ocean as a volcanic hotspot chain. It was considered that the supposed hot-spot should be responsible for the creation of the east-west trending Vitória-Trindade seamount chain, which includes the Trindade and Martim Vaz archipelago at its easternmost end. Trindade, a small island in the archipelago, is the hotspot's most recent eruptive center.

This ideas was based on the geochemical data, especially of the highly silica-undersaturated alklaine ultramafic rocks of the Trindade Island and Martim Vaz Island. The isotopic data is OIB-type, which is favourable to the hot-spot hypothesis. However, the volcanic chain direction is E-W and the absolute motion vector of the South America Plate is NW. Therefore, the volcanic chain cannot be a hot-spot chain. Recent research papers, as Skoletnev et al. (2010) and Motoki et al. (2012), proposed that the hot mantle penetrated horizontally along the Vitória-Trindade fracture zone which is present in the lithospheric mantle. Because of the same reason, the Fernando de Noronha Volcanic chain also is not a hot-spot chain. On the other hand, the NW-SE magmatic alignments, such as the Cruzeiro do Sul Chain, Bahia Chain, and Macau-Queimado, are considered to be hot-spot chains. (Wikipedia) 



 



For wonderful pictures visit the following site: Image via http://en.wikipedia.org/wiki/Trinda...Trindade and Martim Vaz)

Trindade and Martim Vaz (Portuguese: Trindade e Martim Vaz, [tɾĩˈdadʒi i mɐʁˈtʃĩ ˈvas] or [tɾĩˈdadi i mɐʁˈtĩ ˈvas]) is an archipelago located about 1,200 kilometers (740 mi) east of Vitória in the Southern Atlantic Ocean, belonging to the State of Espírito Santo, Southeast Brazil. The archipelago has a total area of 10.4 km² (4.0 sq mi) and a population of 32 (Brazilian Navy personnel). The archipelago consists of five islands and several rocks and stacks; Trindade is the largest island, with an area of 10.1 km² (3.9 sq mi); about 49 km (30 miles) east of it are the tiny Martim Vaz islets, with a total area of 0.3 km² (30 hectares).

 

The islands are of volcanic origin and have rugged terrain. They are largely barren, except for the southern part of Trindade. They were discovered in 1502 by Portuguese explorer Estêvão da Gama and stayed Portuguese until they became part of Brazil at its independence. From 1890 to 1896, Trindade was occupied by the United Kingdom until an agreement with Brazil was reached. During the period of British occupation, Trindade was known as "South Trinidad."

For wonderful pictures visit the following site ("Vulcão de Nova Iguaçu" in Portuguese) is located in the state of Rio de Janeiro, Brazil, in an area of volcanic rocks at the north-eastern border of the Mendanha massif. Klein and Vieira proposed the site to be an extinct volcano with a volcanic cone, volcanic crater, and volcanic bomb. Scientific journals have studied the volcanic geology of the area, identifying the rocks of volcanic appearance as constituted of subvolcanic intrusive rock bodies. The Nova Iguaçu volcano theory is now extinct in academic communities, but the myth continues in sightseeing promotion groups.

 

Recent research revealed that volcanic eruptions did occur in the Nova Iguaçu region. After the eruptions, an intense uplifting and consequent regional denudation took place. The cones, craters, lavas, pyroclastic flow deposits, and volcanic bombs have been washed away in the strong tropical erosion of this region, exposing the underlying geologic structure. The Municipal Park is underlain by the geologic bodies corresponding to the magma chamber (composed of syenite and trachyte) and subvolcanic conduit (made up of pyroclastic rocks) of a depth of 3 kilometers, such as pyroclastic dikes. That is, no extinct volcano is present at Nova Iguaçu. The outcrops are world-rare geological phenomena that expose the underground geologic structures of the volcanic area.

 

 Pico do Cabugi

The Pico do Cabugi, also known as the Serra do Cabuji or Serrote da Itaretama, is the only extinct volcano in Brazil which preserves its original form. It is 590 meters high and is located in the Cabugi Ecological State Park in the municipality of Angicos in the state of Rio Grande do Norte.

Composed mainly of basaltic alkaline intrusive rocks, this volcano was the result of a major geological upheaval in the tertiary era which were responsible for various volcanic cones in the rocky state of Rio Grande do Norte. They have been dated using radioactive isotopes as the most recent of Brazilian igneous rocks (± 19 million years). The presence of small xenoliths indicate that these rocks have originated at a great depth (about 60 km).

 

The researcher Lenine Pinto argues that when Brazil was first discovered by Pedro Álvares Cabral, it was Pico do Cabugi that he first saw and not Monte Pascoal (Wikipedia)


 Picture Iguazú Falls located at the work cited for About 

Taller than Niagara Falls, twice as wide with 275 cascades spread in a horsehoe shape over nearly two miles of the Iguazu River, Iguazú Falls are the result of a volcanic eruption which left yet another large crack in the earth (About).

 

 As you can see above one of the most amazing sites are what a volcano left behind.  When we think about volcano’s we usually think of fire and destruction.  Which is true, just ask those who have lost their home in Hawaii, however, sometimes something beautiful is left behind.  Crater Lake in Oregon is one of the many lakes that have formed in volcanic craters.  What about Yellowstone it is said to be the results of a sleeping giant volcano.

Brazil and Earthquakes by Linda Potter

 

 

Brazil is a very large country and has a very diverse geography.  One of the more recent quakes I could find on the USGS site was for Taracuana  

http://earthquake.usgs.gov/earthquakes/eventpage/usc000p90n#general_map is a site for the Taracuana earthquake in Brazil.  In the information that

 follows you will see that most of the earthquakes are near Brazil and along the western coast of South America.  The following information was found on the USGS site (1 & 3)

Brazil has had: (M1.5 or greater)

·         0 earthquakes today

·         0 earthquakes in the past 7 days

·         0 earthquakes in the past month

·         5 earthquakes in the past year

Not many as you can see for the past year especially when you compare it to other countries the size of Brazil or a bit smaller.

As far as I could find for how prepared and how the Brazilians predict earthquakes I found:

Earthquake Early Warning (Japan) - Wikipedia, the free encyclopediaen.wikipedia.org/wiki/Earthquake_Early_Warning_(Japan)Earthquake Early Warning in Japan: When two or more Seismometers detect ... By doing rough predictions, JMA is able to warn people in prefectures through TV and radio if strong shake is expected. ... Please prepare for powerful tremors. .....
