Seismometers such as this one installed near Mount 
Spurr volcano (on skyline in background) provide the Alaska 
Volcano Observatory with a continuous, radio-telemetered 
record of volcanic earthquakes. These data are used to 
monitor the state of activity at the volcano and are 
critical to the ability of the Observatory to issue timely 
warnings of eruptions. View is to the north. Photograph by
