Earthquake Webquest

1.A. Geologically, most of the earthquakes happen along faults in the Earth's crust. They happen because pressure builds up over many years and when enough of it builds, the crust will shift abruptly, causing an earthquake.

1.B. Geographically, most of the earthquakes happen in cities, states, or countries that lie on faults in the earth's crust. Most earthquakes occur along coastal regions, like Japan and California.

2. I think that they occur in those places because the oceanic crust will push against the continental crust on the coast, so faults will eventually happen. Pressure will build up and earthquakes will happen on those coastal regions.

3. The area where most earthquakes happen is called the Ring of Fire. It is an area of frequent earthquakes and volcanic eruptions in the Pacific Ocean.

4. The earthquake closest to Manitou Springs wasin an area in northern Colorado. It was magnitude of 3 so nobody here could feel it. 100 times the ground shaking occurred compared to a magnitude 1 earthquake. It had about 37,000 more energy released than a magnitude 1 earthquake.

5. There was recently an earthquake in the Taiwan Region. It had a magnitude of 5.6. It didn't hit any major cities, but it could be felt very easily in the cities closest to it.

6. People can protect themselves from the danger of earthquakes by getting underneath something sturdy like a table. They should protect themselves from head injury especially.

HEY! ok so I didn't comment on your post for the Everglades but I had to let you know that piece of writing should be put out to advertise the Everglades. You should write more often. It was so amazingly wonderful. And informative.
