Cerro Prieto - Centre for the Observation and Modelling of Earthquakes, Volcanoes and Tectonics

Observations of Deformation

Volcano number:	341000
Region:	Mexico and Central America
Country:	Mexico
Geodetic measurements?	Yes
Deformation observation?	Yes
Measurement method(s):	InSAR, Levelling
Duration of observation:	1994-2006 (levelling), 1993-1997 (ERS InSAR), 2003-2006 (Envisat InSAR)
Inferred cause(s) of deformation:	Hydrothermal
Characteristics of deformation:	Between 1993 and 1997, ERS InSAR data showed that the Cerro Prieto Geothermal Field was subsiding at up to 6 cm year^-1(Carnec and Fabriol 1999). Sarychikhina et al (2011) used a combination of levelling surveys and InSAR and observed a maximum subsidence rate of 9 cm year^-1between 1994 and 1997 (levelling), 12 cm year^-1 between 1997 and 2006 (levelling), and 18 cm year^-1between 2004 and 2005 (InSAR).
