Tsunami FAQ

By: Henry Sewell

What is a tsunami?

A tsunami is a gigantic wave from a body of water often caused by an earthquake.

Why is it dangerous?

Tsunamis are dangerous because the are ginormous waves, and they could be big enough to flood a city, so hundreds of people could drown and die in these waves if they aren't careful.

What Places Are Most Vulnerable to Tsunamis?

The places that are most vulnerable to tsunamis are any places in the Pacific Ocean's Ring of Fire, since that is where the most tsunamis occur.

How are Tsunamis Measured?

They are measured using their crest length, arrival time, drop, elapsed time, initial rise, intensity, Inundation or Inundation-distance, inundation (maximum), inundation area, inundation line, leading wave, magnitude, mean height, and overflow

What are Some Examples for Tsunamis?

Sumatra, Indonesia - 26 December 2004, where a 9.1 magnitude earthquake hit and a enormous tsunami came. An estimated US $10b of damages is attributed to the disaster, with around 230,000 people reported dead.

North Pacific Coast, Japan - 11 March 2011, a 9 magnitude earthquake hit and "A powerful tsunami travelling 800km per hour with 10m-high waves swept over the east coast of Japan, killing more than 18,000 people."

How Do I Protect/Prepare Myself From Tsunamis?

You could plan evacuation routes from your home, school, workplace and other places you could be where tsunamis present a risk to your life and practice these routes. If you feel an earthquake lasting 20 seconds or longer near the coastal areas, drop, cover, and hold on to protect yourself from the earthquake, then gather your family members and get to higher ground.
