SO2 plumes and Thermal Anomalies from Hawaii Eruption; May, 6th 2018
The slide shows a composite of satellite products to highlight plumes of Sulfur Dioxide and Hot spots from Lava erupting from Mt Kilauea and the new Fissures observed since May 3rd and May 4th in the Leilani areas.  The top panel shows a map of SO2 from the Tropomi sensor on the ESA Satellite Sentinel 5P for May 6th. Two main SO2 plumes are seen on the map emerging from the Kilauea crater ( Red triangle) and another source to the East is also visible. They eventually...

Credits: NASA/METI/AIST/Japan Space Systems, and U.S./Japan ASTER Science Team The eruption of Kilauea Volcano on the island of Hawaii triggered a number of gas- and lava-oozing fissures in the East Rift Zone of the volcano. The fissures and high levels of sulfur dioxide gas prompted evacuations in the area. Images taken from the Advanced...

Hazardous Landslide-dammed Lake, Pisang, Annapurna Region, Nepal
The April 25, 2015 magnitude 7.8 Gorkha earthquake in Nepal produced a landslide dam on the Marshyangdi River, 1.1 miles (1,800 meters) upstream from the village of Lower Pisang. The dam has impounded the river, produced a landslide-dammed lake extending approximately 1,722 feet (525 meters) up the river, and satellite imagery shows that the lake area is expanding with time. Landslide dams can be inherently unstable and may fail suddenly, leading to...
