I’m cheating on the USGS site with a new nerdy website.
Make that two.
I’ve been spending the last few weeks watching and reading all about Eyjafjallajökull, the volcano in Iceland that erupted in April. I’ve been checking out the Eruptions blog (http://scienceblogs.com/eruptions/) and the webcams for the volcano (http://eldgos.mila.is/eyjafjallajokull-fra-hvolsvelli/). The Eruptions blog is filled with comments every day from volcano-watchers and researchers around the world. I get sucked into their threads. It’s such nerdy fun.
The volcano is rumbling a lot right at this moment. Webcam shows huge plume of ash and there have been many earthquakes in the last hour or so (I think). Yeah – I can see those too here: http://en.vedur.is/earthquakes-and-volcanism/earthquakes/.
If it’s any consolation, I still check the USGS site every day also. Arkansas – you just had a 2.5 earthquake!

Funny nothing shows up on the standard USGS site for Iceland which has now had 60 quakes today! I got hooked on the volcano too http://ahrcanum.wordpress.com/2010/05/10/50-earthquakes-under-iceland-volcanos-today/ There is a tab at the top w more data but haven’t had a chance to update it in awhile so you may want to the home page and go back thru older posts for some cool links to follow.
The USGS site only shows worldwide earthquakes that are over 4.5 in magnitude. It looks like the Iceland earthquakes today are all under 3.0.
It was strange for me to see sooo many aftershocks after the Baja California quake in April. I wondered why there seemed to be so many more than normal after a 7+ earthquake. Then I realized that the aftershocks were in California, and I never see the aftershocks under 4.5 for the rest of the world.
