Which type of plate boundary is associated with most killer tsunami quizlet?
In shallow water, the energy of the tsunami must be contained within a smaller water column. What type of plate boundary are most tsunamis associated with? Convergent plate boundaries.
What is the most dangerous tectonic boundaries in term of tsunami generation?
Most of the world’s earthquakes, tsunamis, landslides, and volcanic eruptions are caused by the continuous motions of the many tectonic plates that make up the Earth’s outer shell. The most powerful of these natural hazards occur in subduction zones, where two plates collide and one is thrust beneath another.
Which shorelines are at greatest risk for tsunamis?
Especially vulnerable are the five Pacific States — Hawaii, Alaska, Washington, Oregon, and California — and the U.S. Caribbean islands.
Which tsunami event had the greatest fatalities?
The most devastating and deadliest tsunami was one in the Indian Ocean on Boxing Day, 2004. The tsunami was the most lethal ever to have occurred, with a death toll that reached a staggering figure of over 230,000, affecting people in 14 countries – with Indonesia hit worst, followed by Sri Lanka, India, and Thailand.
Do divergent plate boundaries cause tsunamis?
In a divergent plate boundary, the plates move away from each other. … If the there is a shift, like an earthquake, on the ocean floor and a plate boundary rises or falls, it displaces the water above. The destructive force causes a tsunami to form. Volcanic eruptions and underwater landslides can also cause tsunamis.
How are tsunamis formed at destructive plate boundaries?
Most tsunamis are caused by earthquakes at destructive plate boundaries . Here, an oceanic plate is subducted into the mantle beneath a continental plate. … When the energy exceeds the friction, the plates snaps back into position. This movement thrusts the water above causing a wave to form.
