Kottke – The Concord Consortium: “From 1980 to the present, a timeline map of every earthquake in the world with a magnitude of 5 or above. You can play around with different parameters and data, so you can see where the different tectonic plates are, just see where the biggest earthquakes occurred, or add in volcanic eruptions. You can also draw a cross section and it will show how deep the quakes occurred along that line.”

• About: Seismic Explorer Geologists collect earthquake data every day. What are the patterns of earthquake magnitude, depth, location, and frequency? What are the patterns of earthquakes along plate boundaries?
• Click the play button to see the earthquakes. You can drag the starting time to start playing earthquakes from a later date.Use the Magnitude slider to choose the earthquake size shown on the map. Click the Show plate boundaries button to see the outlines of tectonic plates.
• Make a cross-section to see a three-dimensional view of the earthquakes in a region. Click on the Draw a cross-section line then draw a line on the map. When you are done, click Open 3D view, and see the depths of the earthquakes in that cross-section. What does the pattern of earthquakes in a region tell you about the motion of tectonic plates?
• Seismic Explorer is based on Seismic Eruption, a program created by Alan L. Jones at the State University of New York at Binghamton.
• Seismic Explorer uses earthquake data (magnitude, depth, location, time) from the United States Geological Survey. Earthquake time is reported in Coordinated Universal Time (UTC).
  Volcanic Eruption data comes from the Smithsonian / USGS Weekly Volcanic Activity Report  and Global Volcanism Program, 2013. Volcanoes of the World, v. 4.9.1. Venzke, E (ed.). Smithsonian Institution. Data Downloaded 10/30/2024. https://doi.org/10.5479/si.GVP.VOTW4-2013
