How could volcanic eruptions generate tsunamis?

Answer 1

A massive volcanic eruption can cause the collapse of the volcanic vent resulting in a tsunami.

A volcanic eruption in 1883 destroyed 70% of the island of Krakatoa, causing the mountain to collapse into the ocean and a tsunami that reached a height of 120 feet, which claimed the lives of over 36,000 people.

Volcanic eruptions can generate tsunamis through several mechanisms. One way is when an eruption occurs underwater, causing a sudden displacement of water. This displacement creates a series of waves that propagate outward, forming a tsunami. Additionally, volcanic eruptions can trigger landslides, either on the volcano itself or on nearby coastal areas. These landslides can displace large volumes of water, generating tsunamis. Finally, volcanic activity may also destabilize the flank of a volcano, leading to a collapse and the displacement of water, resulting in a tsunami.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
