Shear wave from earthquake, moving slower than primary waves, through solid material only. Material is sheared side to side, perpendicular to the direction of wave propagation. 4. Epicenter Location on Earth's surface directly above the focus of the earthquake 5. Richter scale Method of earthquake measurement based on the amplitude of seismic ...Measuring Earthquakes. The vibrations produced by earthquakes are detected, recorded, and measured by instruments call seismographs. The zig-zag line made by a seismograph, called a "seismogram," reflects the changing intensity of the vibrations by responding to the motion of the ground surface beneath the instrument.Feb 6, 2023 · Learn about the geophysics behind earthquakes, how they are measured, and where the most powerful earthquake ever witnessed occurred.

An earthquake is happening. Also called a temblor, an earthquake is caused by the movement of parts of the Earth’s crust, its outermost layer. They happen millions of times a year, but most are so small people don’t even feel them. But powerful earthquakes can cause landslides, tsunamis, flooding, and other dangerous events.Determining whether the worst earthquake has passed. When a big earthquake occurs, it is hard to tell if it will be followed by a larger quake or by only smaller ones. A method has been developed ...Earthquakes are among the most destructive natural phenomena on the planet. Their potential for damage and harm exceeds that of most other disasters.
