Earthquake webquest

1.Where do most of the earthquakes tend to happen?
Most Earth quakes occur where plate boundary's move. Most earthquakes occur along the edge of the oceanic and continental plates. .
2.Why do you think that is? Because at the plates the crust of the earth there is very loose and can easily be shaken.

3.What is this area called?
Earthquakes occur at faults.There are three types of faults: normal faults, reverse faults, and strike-slip faults.

4.Where is the earthquake closest to Manitou Springs? What are the details of this earthquake? Would people be able to feel this earthquake? About how much more ground shaking would occur for this magnitude earthquake compared to a magnitude 1 earthquake? About how much greater is the energy released with this earthquake compared to the energy of a magnitude 1 earthquake?
The closest Earthquake to Colorado Springs is in Norther Colorado. Location--40.953°N, 106.930°W. Distance=95miles. Almost 2 times as much ground shaking occured. A 2.2 larger magnitude occured.

5.Choose one earthquake that has happened in the last seven days. You will be researching that earthquake. Tell me all about it. Are earthquakes common in this area? Include at least one picture, preferably of the earthquake, but if you can’t find one include one of the area.
Geologic studies indicate there are about 100 potentially active faults in Colorado and more than 400 earthquake tremors of magnitude 2.5 or higher have occurred in Colorado since 1870. 3.2 Magnitude Earthquake. Northern Colorado. 95 miles away from Manitou Springs, Colorado. Depth=3.1 miles.Location=40.953°N, 106.930°W. Date and Time= Thursday, January 15, 2009. at 12:10:02 PM.
6.How can people protect themselves from the dangers of earthquakes?
Drop and cover, fall on to the floor and get under something for protection. During an earthquake if you are indoors be calm and take cover under something. If you are outdoors, stay as far away from buildings as possible. Stay calm. Be prepared for aftershocks after the main earthquake has ended.
