Seismic waves

Here's an XKCD by Randall Munroe on a geology theme that is a rather fascinating observation. Clicking on the image will make it larger and easier to read. Go to this actual webcomic, hover over the image, and there will be an additional message in the "title-text" . This one says
 The USGS operates a really neat email/SMS earthquake notification service (earthquake.usgs.gov/ens/) that allows fine-grained control of notifications.
Here's the updated link to the USGS service mentioned in the title-text: https://sslearthquake.usgs.gov/ens/
