The Raikoke Volcano on the Kuril Islands in the Western Pacific Ocean erupted around 4:00am local time on June 22nd, 2019. The NASA Disasters Team has activated Tier 1 response for this event and is working with stakeholders at the Alaska Volcano Observatory and the Anchorage Volcanic Ash Advisory Center (VAAC) to provide S02 mass estimates, plume trajectory models, and other satellite data products in support of the event. Since volcanic ash contains fragments of volcanic glass which melts a lower...

The Southern and Central United States have been drenched by rainstorm after rainstorm in the spring of 2019, leading to widespread flooding. Across the continental United States, river gauges at 404 locations were above flood stage on May 29, with the vast majority along the Missouri, Mississippi, and Arkansas rivers and their tributaries. The problem was most acute in late May along the Arkansas River. As of May 29, the National Weather Service reported flooding at 22 gauges along the river in Kansas, Oklahoma, and Arkansas, not including nearby tributaries and lakes. Major flooding was...

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image at 5:22 a.m. Universal Time (10:52 a.m. India Standard Time) on May 1, 2019
Tropical Storm Fani formed in the Northern Indian Ocean over the weekend of April 27 and 28.  The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image at 5:22 a.m. Universal Time (10:52 a.m. India Standard Time) on May 1, 2019. Around the time of the image, the storm had sustained winds of 105 knots (120 miles/190 kilometers per hour). That’s the equivalent of a category 3 storm on the Saffir-Simpson wind scale.

Tropical Cyclone Kenneth made landfall in Northern Mozambique on Thursday April 25, after striking the Island Nation of Comoros earlier in the day. Currently, the death toll in Comoros stands at 4, while Mozambique has had 38 confirmed fatalities. TC Kenneth is a very slow moving storm, dumping extreme amounts of rain over Northern Mozambique. Pemba has already received 22 inches of rain, and up to 20 more inches of rain is possible in the next 5 days. More than 35,000 homes in northernmost Cabo Delgado were partially or fully destroyed by Kenneth. More than 18,000 people have been...

Rivers have reached historic water levels in 41 locations across the Midwest. This devastating flooding that has killed at least three people, forced evacuations in multiple states, breached dams and levees, destroyed roads and bridges, damaged thousands of homes and flooded portions of Offutt Air Force Base. Floodwaters are also threatening a nuclear power plant, and forced the evacuation of a National Weather Service Office on Friday. Continuing snow melt and expected spring rainfall will only extend the length of time that areas are flooded....

Officials report that over 215 people have been killed so far by the effects of this storm, but the expected death toll is over 1,000. Flooding and storm damage have isolated many cities and villages, making it difficult for responders to reach the impacted areas and fully understand the impacts of the storm.  Suomi NPP VIIRS image of Cyclone...
