https://earthquake.usgs.gov/earthquakes/map/ Click on the gear button in the top right. Select “30 Days, Magnitude 2.5+ U.S.” Click on “Zoom to” button in top right of map and select “World” Also select “Largest magnitude first” as an option on the right-side menu

Map 20 Current Earthquakes Click on Earthquakes of your choice on the left-side menu. It should be a light blue circle now. On your map, draw a small circle in the approximate location of the quake. With small letters, next to the circle, write the magnitude, Date, and depth. Eg: M 6.5 (Bouvet Island), 12-13-17, Depth 10 km. Note: you may need to skip a few on the list if they are all in the same location on the map. That’s okay. We need a variety of locations around the world.

Map 20 Current Volcanoes Link: https://www.volcanodiscovery.com/erupting_volcanoes.html (main map down as 1-5-18) You can still access individual volcanoes below the main map and then make them larger to see their locations Alternate link: http://volcano.si.edu/reports_weekly.cfm This site does a weekly update, so you can go to the Archive tab for extras. Use one of the above links to chart 20 current volcanoes with a TRIANGLE Date (or date range) Type of volcano Eg.: Stromboli (off Italy), 16 Dec 17, Stratovolcano

As a class… What are some observations that you can make about the Earthquakes you mapped? How about Volcanoes? What are the patterns for the earthquakes and volcanoes that you note?

What kind of questions do you have about what you’ve observed?

Let’s discuss “Tectonics”
