Imagine that you have no electricity, no gas, no water and no telephone service. Imagine that all the businesses are closed and you are without any kind of emergency services. What will you do until help arrives?

The USGS estimates that several million earthquakes occur in the world each year. Many go undetected because they hit remote areas or have very small magnitudes. The NEIC now locates about 50 earthquakes each day, or about 20,000 a year.
