Volcanoes!

For the next week, starting this morning and continuing through Dec 8, volcanoes will be prominently featured on the blog.  This is largely due to a journal dedicating this month to volcanic eruptions and their impacts in deep time.  However, it won't be exclusively for that reason.  So, in honor of the week of one of the biggest, most frightening events that can take place on Earth, here's a video of an eruption of a volcano in Papua New Guinea.  Wait for the shock wave.
