Earthquakes and tsunamis injure and kill many people.

All of the above
|
|
|
Earthquakes and tsunamis are not costly at all.

Detailed explanation-1: -The high seismicity of such regions is caused by the collision of tectonic plates. When these plates move past each other, they cause large earthquakes, which tilt, offset, or displace large areas of the ocean floor from a few kilometers to as much as a 1, 000 km or more.
Detailed explanation-2: -The most expensive natural disaster is the 2011 TÅhoku earthquake and tsunami, costing an estimated $360 billion.
Detailed explanation-3: -Unlike most volcanoes and earthquakes, tsunamis are not direct consequences of plate tectonics. The most common tsunami trigger is submarine earthquakes, but they can also be set off by a volcanic eruption under, or next to, the sea. Thus volcanoes, earthquakes and tsunamis are part of the same story.
Detailed explanation-4: -Tsunamis inflict damage by two mechanisms: the slamming force of a fast-moving wall of water, and the destructive strength of a large volume of water draining off the ground and bringing a large amount of debris with it, even with small waves.
