Very large tsunamis can cause damage to coastal regions thousands of miles away from the earthquake that caused them. Beaches, lagoons, bays, estuaries, tidal flats and river mouths are the most dangerous places to be. It is rare for a tsunami to penetrate more than a mile inland.
Which area is the most at risk tsunami hazard?
Especially vulnerable are the five Pacific States — Hawaii, Alaska, Washington, Oregon, and California — and the U.S. Caribbean islands.
What areas are most affected by tsunamis?
Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones. However, tsunamis have also occurred recently in the Mediterranean Sea region and are expected in the Caribbean Sea as well.
What are the locations of tsunamis?
U.S. Tsunami Hazard Levels
|U.S. West Coast||High to Very High||94|
|Guam and Northern Mariana Islands||High||25|
|Puerto Rico and the U.S. Virgin Islands||High||13|
Which regions are high risk in terms of tsunamis in the Philippines?
The proximity of Southern Mindanao to Celebes Sea, where undersea earthquakes frequently occur, makes this part of the country most vulnerable to tsunamis. Three of the ten provinces most at risk to tsunamis are located in Southern Mindanao, namely Sulu, Tawi–tawi and Basilan.
Which areas are affected by tsunami in India?
India: Tsunami – A report to the nation
|Tamil Nadu||Kerala||Andaman & Nicobar Islands|
|Population Affected (lakhs)||8.97||0.43|
|Number of villages affected||376||33|
|Cropped Area Affected (hectare)||19168||792|
Which countries were affected by the 2004 tsunami?
The tsunami killed at least 225,000 people across a dozen countries, with Indonesia, Sri Lanka, India, Maldives, and Thailand sustaining massive damage. Indonesian officials estimated that the death toll there alone ultimately exceeded 200,000, particularly in northern Sumatra’s Aceh province.
What are some hazards caused by tsunamis?
Earthquakes and tsunamis can cause fires, transportation accidents, and hazardous material releases into the environment, contaminating water supplies and threatening public health. These impacts can further complicate evacuation, response, and recovery.
What destruction do tsunamis cause?
There are three factors of destructions from tsunamis: inundation, wave impact on structures, and erosion. Strong, tsunami-induced currents lead to the erosion of foundations and the collapse of bridges and seawalls. Flotation and drag forces move houses and overturn railroad cars.
Where are tectonic hazards located?
They occur in bands on tectonic plate boundaries, often on the edges of continents. A number of earthquakes can be seen on Pacific coast of South America, for example in Chile.
