Earthquakes & Tsunamis

Much of what people talk about in day-to-day life revolves around current events, whether local or worldwide. In the past few weeks, there has been much talk about a series of events that caught the attention and concern of many people: earthquakes. Recently, there have been major earthquakes in New Zealand and Japan, and in the previous year, many other nations dealt with the destruction earthquakes and tsunamis bring. Let’s learn a little bit about these natural disasters and what we can do to protect ourselves.

Earthquakes are caused by movements of the earth. The surface of the earth is made up of tectonic plates, like sections of a puzzle. They move around and bump into one another, and sometimes if one moves a lot, it causes an earthquake. Places where these plates come together are called faults. Most earthquakes occur along these fault lines, which is why some places seem to have earthquakes regularly, while other places never do. If the movement of the plates is very small, the earthquake might not even be noticeable, but if it is very large, it can be very destructive. The recent earthquake in Honshu, Japan was the fourth largest earthquake in the world since 1900. These extremely large earthquakes can also cause another frightening disaster: a tsunami. How?

When two plates under water move in just the right way, they can push the water up very quickly, creating an enormous wave called a tsunami. These waves can travel at hundreds of miles an hour, and although they aren’t very tall, when they reach shallow water, they slow down and increase in size and can devastate coastal cities.

How can you protect yourself? Earthquakes come unexpectedly, but you can protect yourself by finding security in the right place. Stand under something sturdy if you are inside, away from the outside of the building. Being under something is your greatest protection, especially for protecting your head and neck. If outside, try to find an open area where things nearby will not crumble or fall over. Tsunamis are sometimes predicted or warned, so people have time to evacuate. If the water at the beach suddenly recedes very far, it is a signal there may be a tsunami on the way. Head for high ground!

These are some simple facts about two very frightening natural disasters that people are seeing around the world more and more. You will hopefully not only be able to talk about them, but also protect yourself from them!
