Hi Bryan

I use 4.5Hz Geophone to detect local and regional earthquakes, at this
moment i don't have a long period seismonitor. This geophone can, if the
condsions are good, you can detect earthquakes down to ~2.4ML at the
range of ~200 km. The frequancy of a local earthquake is from 2Hz to
60Hz, problay higer if you can recorod it. The problem is however that
above 4Hz there is alot of noise. Both from nature and human traffic.

You can check my recordings at the psn webpage.

They are the one with the name "Hvammstangi".
