In response to the news of the catastrophe, researchers at space agencies globally, consisting of NASA, sprang into action, analyzing satellite information to better understand the occasion.
” These were effective and very big earthquakes that ruptured all the way up to the surface over a long series of fault sectors,” stated Eric Fielding, a geophysicist at NASAs Jet Propulsion Laboratory (JPL). “This created exceptionally strong shaking over a huge location that hit many cities and towns complete of people. The rupture length and magnitude of the magnitude 7.8 earthquake resembled the 1906 earthquake that ruined San Francisco.”.
The preliminary damage proxy map above programs parts of the cities of Türkoğlu, Kahramanmaraş, and Nurdaği. Dark red pixels represent locations likely to have severe damage to structures, houses, and infrastructure or changes to the landscape, while orange and yellow locations are moderately or partially damaged. Each pixel measures about 30 meters throughout (about the size of a baseball infield).
The map is obtained from information gathered by the PALSAR-2 on the Advanced Land Observing Satellite-2 ( ALOS-2) on February 8, 2023. The satellite brings a synthetic aperture radar, a sensor that sends out pulses of microwaves toward Earths surface and listens for reflections of those waves to map the landscape, including structures. By comparing the February 8 information to observations made by the same satellite prior to the earthquake (on April 7, 2021, and April 6, 2022), scientists tracked the modifications and started to determine broken areas. The ALOS-2 data were supplied by Sentinel Asia and examined by the Earth Observatory of Singapore– Remote Sensing Lab in cooperation with NASA Jet Propulsion Laboratory and Caltech.
” The map covers just the main part of the afflicted location due to the narrow, 70-kilometer swath of the ALOS-2 fine-beam information utilized, but it includes the epicenters of both the magnitude 7.8 primary earthquake and the magnitude 7.5 aftershock,” said Fielding. “Note that the time periods between the ALOS-2 acquisitions depend on a year apart, so the precision of the damage proxy map may be lower in locations of vegetation, such as in the mountains, due to seasonal variations.” Some of the areas marked as damaged in vegetated areas might not have been damaged, and some areas revealing no damage in vegetated areas might be damaged.
Members of the catastrophes program location of NASAs Earth Science Applied Sciences, in addition to their worldwide and national partners, are in the procedure of sharing the damage proxy map and the data used to generate it with companies such as the U.S. State Department, the California Seismic Safety Commission, Miyamoto Global Disaster Relief, and the World Bank. The team is likewise taking part in continuous coordination calls hosted by the U.S. Agency for International Development to examine the requirements of stakeholders in the area and provide clinical competence to support risk evaluation and recovery efforts.
” Were monitoring this event closely,” said Shanna McClain, the supervisor of the program. “In addition to mapping damage to the extent possible from satellites, were utilizing satellites to track increased landslide dangers, power blackouts, and weather condition that might position obstacles to response efforts.” As new information end up being offered, the group is publishing near real-time images and information products associated with the earthquake on its mapping portal.

The preliminary damage proxy map above shows parts of the cities of Türkoğlu, Kahramanmaraş, and Nurdaği. Dark red pixels represent areas most likely to have serious damage to buildings, homes, and facilities or modifications to the landscape, while orange and yellow locations are moderately or partly damaged. By comparing the February 8 information to observations made by the exact same satellite before the earthquake (on April 7, 2021, and April 6, 2022), scientists tracked the changes and started to determine broken locations.” The map covers only the main part of the affected location due to the narrow, 70-kilometer swath of the ALOS-2 fine-beam data utilized, but it includes the centers of both the magnitude 7.8 main earthquake and the magnitude 7.5 aftershock,” said Fielding. Some of the locations marked as damaged in vegetated areas might not have been harmed, and some locations showing no damage in vegetated areas may be damaged.

Researchers from NASA and other firms are utilizing satellites to map damage triggered by the destructive earthquake in the Republic of Türkiye.
On February 6, 2023, two earthquakes of magnitudes 7.8 and 7.5 hit southern Turkey and western Syria, leading to widespread devastation across both nations.
The preliminary earthquake stemmed from a fault line located 18 kilometers (11 miles) beneath the surface, which led to violent shaking that affected a wide radius from the center. The very first quake was followed by another powerful 7.5 magnitude earthquake 9 hours later on, as well as numerous smaller sized aftershocks.
