Turkey Earthquake January 2020
On Friday January 24th, 2020 a 6.7 magnitude earthquake struck eastern Turkey. NASA's Earth Applied Sciences Disasters Program is monitoring the situation to identify potential stakeholders and determine what NASA resources and capabilities, if any, may be available to support response and recovery for the event.
Soon after the earthquake, NASA scientists reached out to colleagues in Turkey at various universities and government institutions, including the Kandilli Observatory and Earthquake Research Institute, Istanbul Technical University, and Turkish Space Agency. NASA Jet Propulsion Laboratories Advanced Rapid Imaging and Analysis (ARIA) system was automatically triggered and generated interferograms using data from ESA’s Sentinel-1 satellites.
This 6-day interval Sentinel-1 interferoram was generated using data acquired on January 22nd and 28th over descending track 123. The ground motion induced by the 6.7 magnitude earthquake is visible at the center of the image, between Kayapinar and Malatya. In this image each color cycle indicates 2 π phase change, which corresponds to about 2.8 cm displacement in the satellite line of sight.
