East Coast people, first, let me be honest: yes, we’re all giggling about your 5.8 earthquake on this coast.  And no, it isn’t fair, but you probably laugh at our occasional funnel clouds.

Second, it’s still very important to go report what you observed if you felt the earthquake; use this USGS link:

USGS: Did You Feel It?

Why? Because it helps geologists map exact earthquake soil response for specific types of seismic waves, and it helps engineers assess actual and potential damage. I makes everyone safer in the long run.

Even with itty-bitty little quakes…  (Kidding!)

The U.S. Geological Survey (USGS) is one of my favourite agencies and sources of information. They take their science seriously, publish excellent quality material, and put great effort into make the information as available, comprehensible, and interesting to the general public as possible.

Some of the tools they have added to their Earthquake Hazards Program page in recent months are just too cool. Not only can you browse by region and by magnitude for earthquakes around the world, you can also

  • subscribe to reports that will be e-mailed to you daily or weekly
  • subscribe to feeds that will display in your favourite feed reader (e.g., Firefox Live Bookmarks, FeedDemon, Google Reader)
  • download data files you can open in your spreadsheet application (e.g., Excel, Google Spreadsheet, OpenOffice Calc, Lotus Jazz)
  • download KMZ format files that will display in Google Earth!

For example, I currently subscribe to a feed that gives me the list of all earthquakes of magnitude 2.5 and above in the last 24 hours. It displays in Google Reader along with my news and blog subscriptions.

Each feed item — each individual earthquake report — leads to a page that provide data on the quake’s magnitude, type, location, depth, etc.; maps you can view on the USGS site, on Google Maps, or with Google Earth; seismograph charts, and more.  For an example, click on the image above and you’ll see the information on a magnitude 2.5 quake that took place this morning at 06:01:51 AM south of Rio Dell.

Ain’t it cool?
