Observations of Deformation

Volcano number:321030
Country:United States
Geodetic measurements?Yes
Deformation observation?No
Measurement method(s):GPS - continuous, GPS - campaign, Tiltmeter, EDM
Duration of observation:1980 - 1984, 2006 - present
Characteristics of deformation:

In 1980-1984 the U.S Geological Survey established and remeasured a trilateration network of 7 stations at Rainier, using EDM and dry tilt (Dzurisin et al. 1983). No observations of deformation were made (Chadwick et al. 1985).
In 2006 – 2008, 5 continuous GPS receivers were installed of which 5 are still operational (CVO website) (http://earthquake.usgs.gov/monitoring/gps/Pacific_Northwest/). Measurements of a 12 station campaign GPS network were also made in 2008 (http://earthquake.usgs.gov/monitoring/gps/Rainier/) and a tiltmeter is located on the north west flank of the volcano.
