![]() ![]() Kitts and Nevis pledged $1 million in disaster relief. Neighboring countries have stepped up to offer aid and financial support. Countries have offered to help but Covid-19 is complicating evacuation efforts. It goes without saying that scores of flights to and from the region, including Barbados, Dominica, St. Lucia, 47 miles away, have been warned of poor air quality and harmful gases. Residents of Barbados, 124 miles away, have been told to stay indoors, while those living on St. Emergency personnel have likened the landscape to a "battle zone." White ash has covered homes across the island. Transportation remains treacherous because the smoke is so thick. Water and food supplies have been cut off in some areas, forcing the government to drill for water and set up distribution points. While no fatalities or injuries have yet been reported, experts are comparing the magnitude of this event's destruction to La Soufrière's eruption in 1902, which was the country's most catastrophic and killed more than 1,000 people.įorests, farms, homes, and livestock have been destroyed. The program is also investigating satellite-based rainfall estimates to determine potential connections with recent heavy rainfall in the region, and monitoring “hot spots” with the NASA/NOAA Suomi-NPP satellite’s Visible Infrared Imaging Radiometer Suite (VIIRS) to monitor for potential further volcanic activity.This eruption is one of the worst in St. The Earth Observatory of Singapore, supported by NASA’s Advanced Rapid Imaging and Analysis ( ARIA) program and the NASA ROSES A.37 research project “ Global Rapid Damage Mapping System with Spaceborne SAR Data, has provided Damage Proxy Maps (DPM’s) of the region to aid in identifying the location of ash, PDC’s, and regions damaged or destroyed by the volcanic activity. The program is supporting stakeholders from the USGS Volcano Disasters Assistance Program ( VDAP), who are coordinating with local disaster response agencies in Indonesia. The NASA Earth Applied Sciences Disasters program area has activated efforts to monitor the eruption and provide Earth-observing data and analysis in support of risk reduction and recovery for the eruption.

The map was derived from synthetic aperture radar (SAR) data acquired by ESA Copernicus Sentinel-1 satellite observations from before (Aug. The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this Damage Proxy Map (DPM) depicting areas that were likely damaged by pyroclastic flows and lahars in Eastern Java, Indonesia due to the eruption of Semeru volcano starting on Dec. It is also notable that satellite observations did not detect the significant sulfur dioxide emissions that typically accompany a volcanic eruption, which further reinforces the dome collapse theory. This dome collapse triggered pyroclastic density currents (PDC’s) - dangerous and fast-moving avalanches of hot ash, gas and debris – which combined with recent heavy rainfall to produce hot lahars (mudflows) that caused much of the destruction. However, based on initial observations of the conditions around the eruption, researchers from Michigan Technical University have speculated that this recent destructive eruption was caused by dome collapse event rather than a conventional explosive eruption. 7.Īs part of the “ Ring of Fire” and one of Indonesia’s most active volcanoes, Semeru has experienced volcanic activity throughout 2021. About 2,000 people were evacuated from the region, and media reports indicate the deaths of 34 people as of Tuesday Dec. Semeru volcano in Indonesia violently erupted, triggering a series of deadly pyroclastic flows and blanketing nearby villages with ash and debris.
