With the recent earthquakes in Colorado and Virginia it seemed timely to share some of the previous blog posts and other Middle School Portal 2 (MSP2) resources on earthquakes and plate tectonics. The US Geological Survey website tells us that earthquakes are occurring all the time, but it is both their intensity and the depth at which they occur that determines the effect and damage they can cause. The site also has a very interesting FAQ section on earthquakes. In addition, the MPS2 Resource Guide on Plate Tectonics is an excellent primer on this subject with many high-quality resources. Also, you may want to revisit a previous blog post on this subject related to the earthquake in Japan entitled Disaster in Japan.
