Duration of observation:2003 to 2010
Characteristics of deformation:

Bathke et al. (2013) present InSAR data at Tenduruk volcano. They detected a large (~105 km2) region that underwent subsidence at the rate of ~1 cm/yr during this period. Source modeling results show that the observed signal fits best to simulations of a near-horizontal contracting sill located at around 4.5 km below the volcano summit (Bathke et al., 2013). 
The authors interpret the displacement field is the surface expression of an inherited ring fault that has been slowly reactivated during the detected recent subsidence. 
The Turkish National Commission for Volcanology and Chemistry of the Earth’s Interior and Hacettepe University undertake some monitoring in Turkey. Three volcanoes have records of historic activity – Nemrut Dagi, Ararat (Agri Dagi) and Tendürek Dagi. Of these, only Nemrut Dagi, has three seismometers dedicated to the monitoring of the volcano (Brown et al., 2015).
