Why Earthquakes Are So Hard To Predict

published 2 years ago by Neptune Studios

Scientists are trying to figure out if they can predict big earthquakes by simulating small quakes in labs and studying big quakes under the ocean. Thanks to the University of Rhode Island for sponsoring this video.

Seismometer: An instrument that detects changes in the up-down motion of the earth. Seismic body waves: Higher frequency waves released by earthquakes that can move through solid rock. Seismic surface waves: Lower frequency waves released by earthquakes that move along the ground and cause most damage. Earthquake Early Warning System: A network of strategically placed seismometers that trigger emergency warning systems in particular areas when they detect large seismic body waves. Evacuation Clearance Time: The time needed to evacuate a particular population to safety. Earthquake Precursor: An anomalous event that gives an effective warning of an impending earthquake. Transform Faults: Faults where two tectonic plates slide past each other. ___________________________________________ Subscribe to MinuteEarth on YouTube: Support us on Patreon: And visit our website: Say hello on Facebook: And Twitter: And download our videos on itunes: ___________________________________________ Credits (and Twitter handles): Script Writer: David Goldenberg (@dgoldenberg) Script Editor, Video Director & Narrator: Alex Reich (@alexhreich) Video Illustrator: Jesse Agar (@JesseAgarYT) With Contributions From: Henry Reich, Kate Yoshida, Ever Salazar, Emily Elert, Peter Reich Music by: Nathaniel Schroeder: ___________________________________________ This material is based upon work supported by the National Science Foundation under Grant 1654416.
