Los Humeros

Volcano number:341093
Region:Mexico and Central America
Geodetic measurements?Yes
Deformation observation?No
Measurement method(s):InSAR
Duration of observation:2003-2007 (Envisat InSAR), 2007-2010 (ALOS InSAR)
Inferred cause of deformation:
Characteristics of deformation:

No deformation was observed at Los Humeros in a regional ALOS survey of Mexican volcanoes (Chaussard et al., 2013). An Envisat survey of the geothermal field at Los Humeros observed that atmospheric phase contributions dominate the interferograms and mask any deformation signal (Carrasco-Núñez et al., 2015).
