A powerful 7.7 magnitude earthquake (Center: 21.85°N, 95.95°E) struck Myanmar on Friday at 12:50 am (local time). The quake struck near Mandalay, Myanmar’s second-largest city of more than a million people. An aftershock of magnitude 6.4 (21.60°N, 95.95°E) was registered at 13:02 (local time). In response, the CBAS and IRDR initiated emergency mapping activities in the affected areas, mainly the nighttime light and synchronize thermal infrared spectrometer (TIS) data, to support the humanitarian response.

The preliminary results:

• As a result of the earthquake, the total decrease in light in the Mandalay region was 41.0%, including 110 km²  of light increase area and 1912 km²  of light decrease area. 

• The total decrease in light in the Yangon region was 40.7%, including 410 km² of light increase area and 6300 km² of light decrease area.

• The results are for reference only due to the influence of clouds and fog and the shimmering angle of view. 

• Observation of the affected area will continue.
