More Than 100 Landslides Strike Turkey Following Devastating Earthquakes

NASA Earth Observatory images by Lauren Dauphin, using Landsat information from the U.S. Geological Survey. The image was taken by a member of the Expedition 68 crew. The International Space Station Program supports the lab as part of the ISS National Lab to assist astronauts take photos of Earth that will be of the greatest value to researchers and the public, and to make those images easily offered on the Internet.

Satellite image of Turkey got on February 11, 2022, by the Operational Land Imager-2 (OLI-2) on Landsat 9.

Researchers are using satellite images to find landslides following the effective earthquakes that struck in early February.
The magnitude 7.8 and 7.5 earthquakes that shook parts of Turkey and Syria on February 6, 2023, triggered prevalent damage, some of which extended beyond city locations. In the days because the earthquakes struck, lots of brand-new landslides became visible in satellite images.
The Operational Land Imager-2 (OLI-2) on Landsat 9 acquired an image (above-right) that reveals a group of small landslides along a valley east of Sarıseki, Türkiye, on February 14, 2023. The other image (left), also from OLI-2, shows the same location on February 11, 2022, about a year before the earthquakes.

Likewise on February 14, 2023, an astronaut aboard the International Space Station took a photograph (listed below) of a landslide in a canyon near İslahiye, a town in Gaziantep Province in southeastern Türkiye. İslahiye is one of several towns and cities where large numbers of houses were damaged or ruined by the earthquakes.

NASAs Earth Applied Sciences Disasters program area is tracking developments associated with the earthquakes and their after-effects and sharing maps, data, and scientific expertise with multiple stakeholders to help continuous response efforts and run the risk of evaluations.
One part of the group based at NASAs Goddard Space Flight Center determined more than 100 landslides, consisting of numerous in the valley near Sarıseki, using high-resolution data from Planet Labs. The landslide data were included in maps offered to World Central Kitchen to assist the aid group provide food and water to earthquake victims. As brand-new details ends up being offered, the group is posting maps and data products associated with the earthquake on its open-access mapping portal.
