  1. Prelim 2 is in 2 weeks • Next week’s section will be a review • Assignment : send me 2 topics/ questions you want me to review • Email them to me by Sunday at 2 pm • This counts towards today’s section grade

  2. Tectonics in action Over the weekend, there was a magnitude 8.8 earthquake in Chile. There have been over 150 aftershocks magnitude 5.0 or greater, including 8 of magnitude 6.0 or greater.1 The quake originated 35km below the surface of the Earth.2 If you would like to help, check this link: http://www.astro.cornell.edu/~babs/howtohelpchile/howtohelpchile.html 1 http://earthquake.usgs.gov/earthquakes/eqinthenews/2010/us2010tfan/#summary 2 http://earthquake.usgs.gov/earthquakes/eqinthenews/2010/us2010tfan/#details
