Here is a link for the Alaska Volcano Observatory site, which has a variety of things to see. This will pull up the Webicorder part of the site. If you click on for various volcanoes listed, you will see squiggles (there’s a nice scientific term) of various sizes. After clicking several volcanoes it seems they all had squiggles at similar locations, probably at the time of the Japan earthquake(s). There are also Web Cams for most of the volcanoes where you can see the actual volcano.
It being late, I very stupidly forgot to add the link for looking at the Alaskan volcanic seismographs and other features. Unfortunately, since it is now more than 24 hours since the main earthquake, you will have to figure out how to see an early recording.
