|Duration of observation:||2003 - 2010|
|Inferred cause of deformation:||Hydrothermal, Magmatic, Faulting/tectonics|
|Characteristics of deformation:|
Interferograms show a broad areas of uplift on the northeastern flank of Recheshnoi with peak rates of ~1 cm/yr. Superimposed upon this is a localised subsidence signal of up to 0.5 cm/yr. Uplift is modelled as a sill (horizontal disloaction) at 4 – 6 km depth and is thought to be caused by an influx of magma. The subsidence signals sharply bounded and are thought to be due to a small graben sturcture reactivated by subsidence of nearby hydrothermal features Geyser Bight and Hot Springs Cove.
