Observations of Deformation

Volcano number:300230
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:1992 to 2003; 2008 to 2010
Characteristics of deformation:

The eruption at Kizimen volcano began around mid-November of 2010, and finished on December 9th 2012. There is no ground-based deformation monitoring network on Kizimen volcano due to its remoteness, persistently inclement weather, and difficult logistics.
More than 6 cm of surface displacement in the satellite’s line-of-sight (LOS) direction is mapped from multi-temporal InSAR images acquired from 2008 to 2010 (Ji et al., 2013). The authors “preferred explanation is that a magma-filled dike intruded beneath volcano, causing a broad pattern of surface deformation and eventually triggering the eruption that began in mid-November 2010”.
The authors model the deformation with “20 cm of opening of a nearly vertical dike […] The model dike is approximately 14 km long, 10 km high, centered 13 km beneath Kizimen, and strikes NE–SW. Time-series analysis of multi-temporal interferograms indicates that (1) intrusion started sometime between late 2008 and July 2009, (2) continued at a nearly constant rate, and (3) resulted in a volume expansion of 3.2 × 107 m3 by September 2010, i.e., about two months before the onset of the 2010 eruption”.
