Studies of Earthquakes and Earthquake-Related Web Sites

Don Simkovich
Studies of earthquakes and earthquake data are readily available online for the pubic through the Southern California Earthquake Data Center (SCEDC) and the United States Geological Survey (USGS).

SCEDC (California Institute of Technology)
The SCEDC Web site is easy to navigate. Tremors happen everyday in fault-laden Southern California and throughout the state and updates are constantly reported - even on tremors that receive little to no attention.

It's possible to locate tremors and quakes for specific locations in Southern California. Log on to the site and under the welcome message click on "Recent earthquakes in California and Nevada."

A map is shown with a simple legend for earthquakes that happened in the last hour, last day and last week. Scroll down the page to go immediately under the map and find the link that reads "Relative2me - Which earthquakes happened near you?"

Click on the link and then enter your Latitude and Longitude to find out the most recent earthquakes. If you don't know the information, and how many of us know our latitude and longitude off the tops of our heads, click on the phrase "Don't know your coordinates? Try the Lat-Long Finder." This will take you to map where you can zoom in to a specific location and the latitude and longitude is automatically displayed on the map.

The SCEDC site also links to the USGS site for some features.

USGS
Log on to the USGS home page. In a box to the right are 18 topics including Earthquakes. Click on the link to reach a page that gives a definition of earthquakes and has a large volume of resources including the Earthquake Hazards Program and Earthquakes: Frequently Asked Questions.

The site is valuable for teachers, journalists, or any one needing to learn about earthquakes, related safety issues, and scientific research. There is also a link to the Advanced National Seismic System with a detailed map nationally and by state of earthquake occurrences.

California Emergency Management Agency
The California Emergency Management Agency is a statewide repository of data and earthquake preparedness information. The California Office of Emergency Services quoted the USGS on the page saying the 7.2 quake near Mexicali and Calexico was the strongest to hit the region in two decades.

The site also links to the California Earthquake Preparedness Survey which states that a family should have enough supplies to last at least 72 hours. An earthquake kit should contain:

- food
- water
- flashlight and battery operated radios

Prepare a kit specific to the family's needs that may include prescription medications and diapers. Keep cash on hand since ATMs may not work after a large quake or transportation to reach an ATM may not be accessible.
