|Region:||Canada and Western USA|
|Measurement method(s):||GPS - continuous|
|Duration of observation:||2000 - present|
|Inferred cause of deformation:|
|Characteristics of deformation:|
There are three GPS receivers that make up the continuous deformation monitoring network at Coso volcanic field. These receivers are part of the 46 instruments that make up the network monitoring Long Valley Caldera. (http://earthquake.usgs.gov/monitoring/gps/LongValley/) Significant uplift at Long Valley was measured in the years 1978-1983, 1990-1995, 1996, and 1997-1998. See Long Valley Caldera for details of deformation observed.
