Mt. Fuego eruption
  It is one of Central America’s most active volcanos. Volcán de Fuego puffs continuously without notice by nearby communities, punctuated by episodes with explosive activity, huge ash plumes, and lava flows. The Guatemalan volcano is at it again, beginning its latest bout of unruly behavior on January 31, 2018. On the next day, the Operational Land Imager (OLI) on Landsat 8 captured these natural-color images of the eruption. Ash in a volcanic plume typically appears brown or gray, while steam appears white. You can see a wider view of the volcano here. Fuego is located about 70 kilometers (40 miles) west of Guatemala City. According to the Coordinadora Nacional para la Reducción de Desastres (CONRED), the plume reached an altitude of 6,500 meters (21,300) feet above sea level and was carried 40 kilometers (25 miles) to the west and southwest by the winds. Falling ash affected tens of thousands of people, primarily in the provinces of Escuintla and Chimaltenango. Lava from two active conduits flowed through four ravines, leading officials to preemptively close National Route 14 to vehicles.

A groundbreaking new study by researchers at Old Dominion University and the NASA Jet Propulsion Laboratory (JPL) challenges decades of conventional wisdom about the sinking of land in southeastern Virginia. That land in Hampton Roads is sinking is not in question. But David Bekaert, radar scientist at JPL, and Ben Hamlington, assistant professor of ocean, earth and atmospheric sciences at ODU, have gathered data suggesting that land subsidence is occurring at substantially different levels in different parts of the region.

NASA’s satellite instruments are often the first to detect wildfires burning in remote regions, and the locations of new fires are sent directly to land managers worldwide within hours of the satellite overpass. Together, NASA instruments, including a number built and managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, detect actively burning fires, track the transport of smoke from fires, provide information for fire management, and map the extent of changes to ecosystems, based on the extent and severity of burn scars.

Water is coming. Where will it hit first and hardest? That’s something residents can see for themselves using an interactive flood prediction map devised by the Virginia Institute of Marine Science and validated by data collected by hundreds of citizen-scientists during last fall’s king tide tracking event.

Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on January 9. NASA calculated the amount of rain fall between January 8 and 10, 2018 and calculated the potential for landslides.

This workshop will identify challenges and gaps in the incorporation of remote sensing and modeling into coastal hazards decision-making, and will assist NASA to build capacity for research and disaster response related to individual and cascading coastal hazards.

Murray, who is based at Langley Research Center, keeps an eye on them all because natural catastrophes are his job. He’s an associate manager of NASA’s disasters program. In its fiscal year ending Sept. 30, the agency responded to 106 disastrous events worldwide, providing data and images from its network of satellites and aircraft. That information has been used for everything from positioning power restoration crews in the wake of hurricanes to crafting no-fly zones after volcanic eruptions. “If there’s a major event anywhere, we’re providing something to somebody,” Murray said.

NASA announced Sept 26 that Old Dominion University researcher Ben Hamlington will serve as the agency's Sea Level Change Team (SLCT) for the next three years. The new SLCT consists of eight members selected from 20 research proposals. Hamlington's research proposal, "Identifying, Quantifying and Projecting Decadal Sea Level Change" was chosen from five proposals to lead the team. According to NASA, the program is intended to integrate research to improve the accuracy of sea level rise estimates and communicate those results in a simplified manner to the scientific community and general public.

A team of NASA scientists is using a high-altitude aircraft and a sophisticated imaging spectrometer to study environmental impacts caused by the devastating Southern California wildfires. NASA’s ER-2, based at Armstrong Flight Research Center in Palmdale, California, flies as high as 70,000 feet (21,300 meters), almost twice as high as a commercial airliner. NASA uses the unique perspective of the ER-2 for science research missions over much of the world. This month, the aircraft has been flying locally over California, testing early versions of science instruments that may one day be launched into space on board a satellite to observe our home planet Earth.

GPM IMERG rainfall accumulation 1/8/18 - 1/10/18
GPM IMERG rainfall accumulation 1/8/18 - 1/10/18 . Winter rains falling on recently burned ground triggered deadly mudslides near Santa Barbara, California on the 9th of January. This rainfall analysis was constructed using NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data. Precipitation data acquired from satellites in the GPM Constellation during the period from January 8-10, 2018 were used in this rainfall accumulation map. This analysis shows the heavy rainfall that occurred over California during the past three days. The heaviest rainfall in this analysis is shown over the Sacramento Valley where over 8 inches (203 mm) were indicated. Southern California had heavy rainfall but the effects of the drenching rain was magnified by the bare soil left by last months wild fires. A rainfall total of 5 inches (127 mm) was reported in Ventura County.
