Rare but Possible A tsunami in the Atlantic Ocean is a rare event. Part of the reason for this low incidence of tsunamis is the lack of subduction zones - the most common source of tsunami-causing earthquakes. Although the incidence of Atlantic tsunamis is low the threat should be taken seriously because millions of people live in low-elevation locations around the rim of the Atlantic basin.
The travel time maps below show that once a tsunami is generated the response time for mass evacuation can be uncomfortably short. Subduction Zones The only subduction zones in the Atlantic basin are along the eastern edge of the Caribbean Plate and the eastern edge of the Scotia Plate in the South Atlantic.
These subduction zones are small, they are not exceptionally active and that accounts for the low incidence of earthquake-generated tsunamis. It generated a tsunami with a run-up height of 6 meters that cause extensive damage and killed over people.
A travel time map for this tsunami can be seen below. It was caused by a magnitude 8. This earthquake and associated tsunami destroyed most of the city of Lisbon. Waves up to 12 meters high hit the coastlines of Spain and Portugal just minutes after this earthquake.
Over nine hours later waves with seven meter runup heights arrived in the Caribbean and caused significant damage. The earthquake and tsunami killed between 60, andpeople.
A travel-time map for this tsunami is shown below. Submarine Landslides Submarine landslides have caused tsunamis in the Atlantic Ocean.
On November 18,an earthquake on the southern edge of the Grand Banks, south of Newfoundland, triggered a large submarine landslide that generated a tsunami. That tsunami was recorded all along the eastern coast of the United States and in the Caribbean.
At least 28 people were killed in Newfoundland. A travel time map for this tsunami is shown below. Some researchers believe that a large landslide in the Canary Islands could generate a tsunami with basin-wide impact.
Faults on the southwest side of La Palma Island associated with Cumbre Vieja Volcano could be the detachment surface of a mega-landslide see image at right. Puerto Rico - October 11, A magnitude 7. The earthquake generated a tsunami with runup heights reaching 6 meters, causing extensive damage along the western and northern coasts of Puerto Rico.
Map and caption by NOAA. Grand Banks - November 18, On November 18, a magnitude 7.
The earthquake was felt as far away as New York and Montreal. It triggered a large submarine slump which ruptured 12 transatlantic cables in multiple places and generated a tsunami. The tsunami was recorded along the east coast of Canada and the U.
The image above shows locations of reported tsunami observations along the eastern United States and through the Caribbean. If you visit their interactive map website you can query any point shown above for more information.
Surface and submarine investigations show a long-term history of mega-landslides at multiple locations in the Canary Island chain. Much of the research focuses on the Cumbre Vieja volcano on the Canary Island of La Palma shown in the satellite image above. Failure along faults on the southwestern side of the island could produce a landslide with basin-wide impact Article.
The earthquake generated a tsunami that affected the coasts of Portugal, Spain, North Africa, and the Caribbean. The tsunami reached Lisbon about 20 minutes after the first destructive shock. It rose to about 6 meters at many points along the Portguese coast and reached 12 meters in some places.
It also affected the coast of Morocco where the streets of Safi were flooded. The tsunami reached Antigua about 9.The Indian Ocean earthquake, and series of catastrophic tsunamis that followed in its wake, had a lesson to teach.
The world community needs to put in place early detection systems, possibly sponsored by the United Nations, that would undoubtedly save benjaminpohle.comgh this earthquake happened close to large population centers that had little time to act even with warnings, nations farther.

The New Madrid earthquake was a mid-plate occurrence while the Great Lisbon Earthquake and tsunami was caused by strong transform fault movement along the boundary of 2 continental plates. In turn, both of these subjects seem to have different tectonic considerations from the balance of the assigned topics for student talks today.
Large. In Europe the Lisbon earthquake caused considerable damage in Spain - particularly in Madrid and Seville.
The tsunami crossed the Atlantic Ocean, reaching the Lesser Antilles in the afternoon. Reports from Antigua, Martinique, and Barbados note that the sea first rose by m, followed by large waves.
The Lisbon earthquake was one . to 1 million years ago: PREHISTORY. The granite areas were formed and weathered down to more like we see today. The dinosaurs came and went and flowering plants evolved, the climate was tropical and dominated by monsoons. Event.
