Dear IRIS colleagues, I recently had the fun of presenting the IRIS opportunity to a group of attendees to the CAPCUE conference (Capitol Computer Users in Education) in Sacramento, CA. I put together a Powerpoint for the presentation that summarizes the seismograph program specifically and offers other resources for Earth science teaching. If the presentation would be of use to you, you can find it at http://www.djusd.k12.ca.us/valleyoak/bstorm/professionallinks.htm, along with a resour... [more]

The October 15, 2006 M6.7 Hawaii Earthquake and Seismograms The October 15, 2005 M6.7 earthquake on the west coast of the big Island of Hawaii was an interesting event. As with many moderate to large earthquakes, it occurred suddenly and unexpectedly. Our recent memory suggests that this was an unusually large earthquake for Hawaii. It is a observed that Hawaii has many small earthquakes associated with volcanic activity, the Hawaiian hotspot and the stresses on the oceanic litho... [more]

Thanks for a great weekend! I returned and was trying to work with the seismograms and discovered that my version of Amaseis was different from the one I was working with this weekend. I looked and it is Version 1.1 but couldn’t remember if that is the latest version. So I went to the IRIS website and downloaded the latest version available, but it was the same as what I have. Where can I find the download of the latest version? With my current version I am unable to set the ... [more]

Hi, I do some rudimentary moment tensor "beachball" work with my high school freshmen, and I was wondering if there are alternative sources for moment tensor solutions. I'm waiting to see if the N. Korea nuke test, which showed up on the world seismicity map, will get a moment tensor posted. A solid color beachball would be interesting to observe, especially because I show it to them as an example of a non-tectonic seismic source. Also, do all the earthquakes in the USGS lists eventually get... [more]

I have a question for everyone. I'm new to seismology and have just gotten our AS-1 running nearly to my satisfaction. Can anyone tell me why the background vibration for a number of stations this morning picked up suddenly? At around 2:00-3:00 UTC, it picked up for 4-5 hours prior to the Kuril Islands' 6.2 event. I saw this on SUNY Binghamton, Iowa, and several other locales. I've seen this a number of times. Thanks. Michael Breed Chenango Valley High School Science Dept. 1160 Chenang... [more]

The Kuril Islands earthquake provides an opportunity to see how filter settings can effect the appearance of the helicorder record in AmaSeis. Two filters are involved, a high-pass filter and a low-pass filter. A "high-pass filter" allows frequencies higher than a set corner frequency to pass unchanged, while attenuating lower frequencies. A "low-pass filter" allows frequencies that are lower than a set corner frequency to pass unchanged, while attenuating higher frequencies. When bot... [more]
