Installing Broadband Seismometers on the Islands Placing the seismometer in a vault | Emilie Hooft Toomey about to install a seismometer in a vault, San Cristobal, 1999 |
Emilie Hooft Toomey prepares to lower a Streckheisen, STS-2 into a vault. The STS-2 is a broadband, three component seismometer that records ground motion over a wide range of frequences (<0.01 to 50 Hz). These seismometers provide high quality recordings of both local and teleseismic earthquakes. They were installed in September of 1999 and will be recovered in the fall of 2002.
