Scales we use to measure hazards

Scales Used to Measure Earthquakes
  • The Richter Scale. The Richter scale was invented in the 1930s by Dr. Charles Richter, a seismologist at the California Institute of Technology. ...
  • The Mercalli Scale. The Mercalli scale measures the intensity of an earthquake by quantifying the effects of an earthquake on the Earth's surface. ...
  • Moment Magnitude Scale.

Vocabulary and Definitions for Tools we Use

Avalauncher

DART: DART = deep-ocean assessment and reporting of tsunamis system. A collection of sensors and buoys that detect potential tsunamis and warn people in coastal areas

seismometer: A device for detecting and measuring the intensity of an earthquake. Also known as a seismograph.

tiltmeter: A device placed on a volcano that can detect changes in the size of the volcano due to increased magma volume. Used to help predict impending eruptions.
