    Olympia, the Sanctuary of Zeus and venue of the Olympic Games in Ancient Greece, was probably destroyed by tsunamis that reached far inland, and not as previously believed, by earthquakes and river flooding... Paläotsunamis that have taken place over the last 11,000 years along the coasts of the eastern Mediterranean. The Olympic-tsunami hypothesis has been put forward due to sediments found in the vicinity of Olympia, which were buried under an 8 metres thick layer of sand and other debris, and only rediscovered around 250 years ago. "The composition and thickness of the sediments we have found, do not fit...
  • SHIP-SINKING MONSTER WAVES REVEALED BY ESA SATELLITES

    Ship-sinking monster waves revealed by ESA satellites   Rare photo of a rogue wave     21 July 2004  Once dismissed as a nautical myth, freakish ocean waves that rise as tall as ten-storey apartment blocks have been accepted as a leading cause of large ship sinkings. Results from ESA's ERS satellites helped establish the widespread existence of these 'rogue' waves and are now being used to study their origins.  Severe weather has sunk more than 200 supertankers and container ships exceeding 200 metres in length during the last two decades. Rogue waves are believed to be the major...
  • Scientists discover huge mega tsunami 73,000 years ago. Could it happen again?

    Waves the size of the Chrysler building may seem like they belong in a movie trailer, but scientists have recently found that megatsunamis are all too real. Scientists say that 73,000 years ago, a large flank (or slope) from the volcanic island Fogo in the Cape Verde islands off the coast of Africa fell into the ocean and triggered a tsunami that could – quite literally – move mountains. “You’re displacing a huge mass, which must generate movement of water,” Ricardo Ramalho, the lead researcher behind the study, told The Washington Post. “And in the case of volcanic flank collapses...

    Geologists think that the eastern slope of Fogo volcano crashed into the sea some 65,000 to 124,000 years ago, leaving a giant scar where a new volcano can be seen growing in this satellite image. Credit: NASA ========================================================================================================================================= Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean tsunami that dwarfed anything ever seen by humans. The researchers say an 800-foot wave engulfed an island more than 30 miles away. The study could revive a simmering controversy over whether sudden...

    Researchers plot course of ancient American tsunami Researchers have calculated the scale of a giant wave that devastated the north west coast of America 1,100 years ago. Japanese scientists used computer modelling to recreate the devastation from the ancient tsunami. The team from the Disaster Reduction and Human Renovation Institution in Kobe say the work will help planners minimise the impact of any future wave. The researchers took clues from silt deposits found in the Puget Sound, a Pacific inlet above earthquake fault lines in the Seattle area. Experts say the tsunami could have reached up to seven metres in...

    MORE than 270 earthquakes have been recorded in just ten days near Spain’s Canary Islands raising fears of a volcanic eruption. The quakes have struck near Tenerife and Gran Canaria in the Canary Islands where there is a huge submarine fault between the two islands. Spain’s National Geographic Institute said the biggest recent quake reached a magnitude of 3.2 on the Richter scale at only about 35km from Puerto La Luz in Gran Canaria. A report said the fault line has not been active in recent times, but it added, “What if it started spewing magma again? And what if...

    How a tsunami develops A tsunami is made up of a series of travelling ocean waves of extremely long wavelength. They are triggered by large disturbances such as earthquakes, undersea volcanic eruptions or deep sea landslides. The figure below shows the amplitude, trough and crest of a tsunami wave in relation to the sea floor and still water level. Note how the wave shape changes and the height increases as it approaches the coastline. Effects of tsunami Tsunami are a threat to people and property in coastal and low-lying estuarine areas. The waves travel quickly, rapidly flooding and damaging coastal...

    The volcanic activity, principally at the convergence of the three ridges, resulted in the continual expansion of the island. A mere 50,000 years ago, as a result of seismic tremors which produced massive landslides, a giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed. This landslide of more than 300km3 gave rise to the impressive amphitheatre of the El Golfo valley and at the same time caused a tsunami that most likely rose over 100 metres high and probably reached as far as the American coast.

The large Teide volcano, the highest point in Spain, looms over the horizon. Shining above are familiar bright stars of Orion, the Hunter. Adding to the dreamlike scene is the 1 meter diameter prototype telescope of the global network project called the Stellar Observations Network Group or SONG. The SONG's fully robotic observatory was captured during the 30 second exposure while the observatory dome, with slit open, was rotated across the...

    PARIS (AFP) - "The sea was driven back, and its waters flowed away to such an extent that the deep sea bed was laid bare and many kinds of sea creatures could be seen," wrote Roman historian Ammianus Marcellus, awed at a tsunami that struck the then-thriving port of Alexandria in 365 AD. "Huge masses of water flowed back when least expected, and now overwhelmed and killed many thousands of people... Some great ships were hurled by the fury of the waves onto the rooftops, and others were thrown up to two miles (three kilometres) from the shore." Ancient documents...

    It's a terrifying vision: A violent eruption of Italy's Mount Etna triggers a massive collapse of one flank of the volcano, sending 35 cubic kilometers of debris--the equivalent of 10,000 Cheops pyramids--hurtling at 400 kilometers an hour into the Ionian Sea. The Big Splash unleashes a 50-meter-tall wall of water that, within a few hours, wipes out coastal settlements across the Mediterranean. This catastrophe happened 8000 years ago--and a Mediterranean monster of similar magnitude could happen again. That's the scenario invoked in an analysis in last week's Geophysical Research Letters. "It was an extraordinary event, probably the largest tsunami unleashed...

    Fossil Frank has a hypothesis - inspired by certain shells taken from deep in a limestone quarry abutting the Everglades - that a great tsunami hit Florida about two million years ago. It happened in the evening - and he can prove it. More of this later. Before Frank Perillo became Fossil Frank he was an unhappy mechanic. He hated every day he lay on his back in Ketcham's garage. Winter days were worst, because his hands turned to meat from the cold and the lacquer thinners he used to wash himself. When he jacked up cars, the ice on...

    Experts in the Azores have alerted the population of Săo Miguel Island for seismic activity which they considered to be above normal. The seismic events where located in the system of Fogo and Congro lakes, the central region of the island. “The situation is ongoing and the number of microseisms is slightly above reference values” said Wednesday Joăo Luís Gaspar from the Center of Volcanology and Geological Risk Assessment (CVARG) of the University of the Azores.

    There sure is a lot of talk about how "global warming" is about to destroy the planet! And how, if we don't stop driving our SUVs – and go back to living by candlelight – we'll all be dead within the next 20 years. (Just ask your children; that's what they probably already believe.) But I'd like to propose that there are much worse catastrophes we really should be worried about. Here is my list of the Top 8:

    Iceland's Eyjafjallajokull wreaked havoc on European air travel, but it could have been worse. Much, much, much worse The eruption of Iceland's Eyjafjallajokull caused billions of dollars in economic damage, and left millions of travelers stranded. But on the Volcanic Explosivity Index — volcanologists’ tool for rating the severity of an eruption — the event rated only a two out of a possible eight. More severe eruptions cause “death and destruction” on a planetary basis, points out Simon Winchester in The Guardian. “They can darken skies and cause devastating changes in the weather. They can and do bring about the...

    MADRID: A wall of water up to 55 yards high crashing into the Atlantic seaboard of the United States, flattening everything in its path — not a Hollywood movie but a dire prophecy by some British and US academics. As the international community struggles to aid victims of last month's devastating tsunami in southern Asia, scientists warn an eruption of a volcano in Spain's Canary Islands could unleash a "mega-tsunami" larger than any in recorded history. According to their controversial study, an explosion of the Cumbre Vieja volcano on the island of La Palma could send a chunk of rock...

    Did anyone watch the Discovery channel on MegaTsunamis over the weekend? Basically, a huge chunk of the island of La Plama in the Canaries is in danger of collapsing into the sea, which would set off a tidal wave washing 12 miles inland on the east coast of the US. I've heard from a contact in the Army that there are serious worries that bin Laden could try to set off a nuke on La Palma that would trigger the collapse. Should Discovery have been allowed to show this? Should the US station troops on La Palma?

    It hardly raised a ripple when it was reported over the summer, but news that a tsunami could one day hit New York is suddenly getting a second look. Several months ago, geologists raised concerns that an unstable flank of a volcano in the Canary Islands off the coast of Western Africa could slide into the sea and send giant waves across the Atlantic at the speed of a jumbo jet. Within three hours, the wave could swamp the west coast of Africa. Within five hours, it could hit southern England, and within 12 hours, it could build up...
