  1. Weston Observatoryin the 21st Century... Seismology Research Science Education • Earthquakes • Monitoring Planet Earth • Earth’s Interior • Earth Processes Science Education and Public Outreach Through Seismology Public Outreach

  2. Recorded at Weston Observatory Magnitude 6.5 – Bali Sea Magnitude 9.0 Near East Coast of Honshu, Japan Magnitude 6.5 - Japan Aftershock

  3. Boston College Educational Seismology Project Costa Rica Magnitude 7.6 September 5, 2012 Devlin Hall, Boston College Gleason Public Library Carlisle, MA

  4. Recording Earthquakes Epicenter Seismic Waves • Seismic waves are vibrations that travel through the Earth carrying the energy released during an earthquake. • Seismic waves travel outward in all directions, like ripples in a pond.

  5. Virginia Earthquake Recorded at Weston Observatory August 23, 2011

  6. Magnitude 5.8 VIRGINIATuesday, August 23, 2011 at 17:51:04 UTC An earthquake in central Virginia was felt across much of the East Coast on Tuesday, causing light damage and forcing hundreds of thousands of people to evacuate buildings in New York, Washington and other cities. There were no reported deaths, and scattered reports of minor injuries. Air and train traffic was disrupted across the Northeast and mid-Atlantic. Two nuclear plants in Virginia were immediately taken offline after the earthquake. Image courtesy of the US Geological Survey

  7. Where people reported feeling the effects of the Virginia earthquake (green) compared with where a magnitude 6 earthquake in California was reported as being felt (blue). California Magnitude 6.0 September 28, 2004 Virginia Magnitude 5.8 August 23, 2011 Adapted from Horton (2012) (Data from U.S. Geological Survey, “Did you feel it?” website)

  8. PlateTectonics Explains Most Earthquakes But, then there are these “troublesome” (not always so little) earthquakes in the middle of the plates... “Intraplate” Earthquakes

  14. Magnitude 9.0 NEAR THE EAST COAST OF HONSHU, JAPANFriday, March 11, 2011 at 05:46:23 UTC Japan was struck by a magnitude 9.0 earthquake off its northeastern coast on March 11, 2011: Largest earthquake ever recorded in Japan and the 4th largest earthquake ever recorded in the world. . In downtown Tokyo, large buildings shook violently and there was severe flooding due to a tsunami generated by the earthquake. USGS ~16,000 fatalities Part of houses swallowed by tsunami burn in Sendai, Miyagi Prefecture (state) after Japan was struck by a strong earthquake off its northeastern coast Friday, March 11, 2011. New York Times Japan's worst previous quake was in 1923 in Kanto, a magnitude 8.3 quake that killed 143,000 people.
