A 7.5-magnitude earthquake on Sept. 28 in northern Indonesia and the devastating tsunami that followed it killed more than 1,400 people and left a large trail of destruction.
This map, produced by NASA's Advanced Rapid Imaging and Analysis (ARIA) team, shows that damage. The map covers an area of about 42 by 44 miles (67 by 70 kilometers), shown by the red polygon. Each pixel measures about 33 yards (30 meters) across. The color variation from yellow to red represents increasingly more significant ground surface change, or damage likely caused by the earthquake and tsunami.
Abnormally heavy monsoon rains drenched Southeast Asia, leading to the worst flooding in the state of Kerala since 1924. The event, which started with rains on August 8, 2018, displaced over 300,000 people, led to hundreds of deaths, damaged over 50,000 houses throughout the region, and severely affected 13 of the 14 districts in Kerala. While it brought the region's most intense flooding this summer, the rain was one of many high precipitation events in Kerala this monsoon season.
Heavy seasonal rainfall has recently caused flooding in Kenya and NASA analyzed and estimated the total rainfall using data from a suite of satellites and gauges.
The heavy rainfall has resulted in the displacement of over 244,000 people. This deluge follows the severe drought that afflicted East Africa in 2017. The estimated death toll from flooding and mudslides has recently been increased to about 100 people.
NASA-NOAA’s Suomi NPP satellite passed over Tropical Cyclone Ava as it made landfall along the coast of northeastern Madagascar.
On Jan. 5 at 5:24 a.m. EST (1024 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite showed the eye of Ava over the northeastern coast near Mahavelona. Mahavelona is a town located in the district of Toamasina II, in the region of Atsinanana. The eye is about 10 nautical miles wide on satellite imagery.
NASA's Terra satellite passed over the Northwestern Pacific Ocean and found newly formed Tropical Storm Tembin in the Philippine Sea as it was nearing the southeastern Philippines.
