What are Tsunamis?
Defined by the NOAA (National Ocean and Atmospheric Administration) , a tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions.
Why are they so dangerous?
Tsunamis are so hazardous to humans because they are highly destructive and hard to pinpoint and track.
Tsunamis are measured via satellites, tide gauges, and the DART System, which is used by NOAA. They are usually classified by how tall the wave is.
Those who live near coasts that are on tectonic plates are in the most danger from tsunamis.

An undersea earthquake caused this tsunami, and over 200,000 people are estimated to have lost their lives. This tsunami was one of the biggest natural disasters in modern history. The photo below is from this tsunami.
How can humans prepare/protect themselves?
- Know the history of the area you live in. If your area has a history of tsunamis, you may be in danger.
- A very recent earthquake and sudden changes in ocean water levels indicate a tsunami is coming.
- The best way to protect yourself if a tsunami is about to hit is to get away from the coast as fast as possible if these warning signs occur.
- Keeping emergency supplies at hand will help immensely if any natural disaster occurs-enough to last at least 72 hours.
