Hang objects from closed hooks and secure corners with earthquake putty. Secure cabinet doors with latches to prevent items from falling out during an earthquake. During an earthquake: Drop, Cover, and Hold on! Drop to the floor, get under a sturdy table, and hold on until the shaking stops. Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs. Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10.

The seismograph and the seismoscope are the two main instruments used to measure the strength of earthquakes. The seismoscope is a simple instrument that measures the time that an earthquake takes place. The seismograph records the motion o...An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.This includes: 1) the actions you should take when an earthquake occurs, 2) the safe places in a room such as under a strong desk or along interior walls, and 3) places to avoid such as near windows, large mirrors, hanging objects, heavy furniture, and fireplaces. Stock up on emergency supplies. These include: battery operated radio (and extra ... The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.
