|Region:||Canada and Western USA|
|Measurement method(s):||GPS - continuous|
|Duration of observation:||1995 - present|
|Inferred cause of deformation:|
|Characteristics of deformation:|
GPS receivers near the Inyo craters (also referred to as the Mono-Inyo Chain) 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.
