With the tagline, “It’s natural science from the inside out”, the USGS has made available a series of podcasts they are calling Corecasts. Each podcasts is relatively short (ranging from two to fifteen minutes in length) and addresses a range of topics such as “When is an Earthquake not an Earthquake?”, “Polar Bear Research”, and a series of podcasts dedicated to Earth Sciences week. The series also includes a monthly roundup covering the previous month’s hazards from around the world. You can sign up to receive an email alerting you whenever a new corecast is posted to the site or subscribe to a feed via RSS or iTunes.
