Lokon-Empung

Observations of Deformation

Volcano number:266100
Region:
Country:Indonesia
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR, GPS - continuous
Duration of observation:2009 - 2011
Inferred cause(s) of deformation:Magmatic
Characteristics of deformation:

Displacement rate of Lokon GPS observation points in the period of 2009 – 2011 ranged from 1.1 to 7 cm a year. Strain patterns that occur in the areas are compression surrounding Tompaluan crater and extension in the eastern slope. Location of the pressure source for August 2009 – March 2011 measurement was at a depth of 1800 m beneath Tompaluan crater. Deformation in the Lokon Volcano is characteristized by the compression zone in the summit and crater area caused by magma activity raised into the surface from a shallow magma source which is accompanied by a high release of volcanic gases. Accumulated pressure release and deformation rate as measured in the Lokon Volcano remain low. Reference 1
