For the past two weeks NASA scientists and satellite data analysts have been working every day producing maps and damage assessments that can be used by disaster managers battling the Woolsey Fire near Los Angeles and the Camp Fire in Northern California. The agency-wide effort also deployed a research aircraft over the Woolsey Fire on Nov. 15 to identify burned areas at risk of mudslides in advance of winter rains expected in the area.
In the aftermath of Hurricane Florence, which struck the Carolinas on Sept. 14 causing widespread damage, NASA quickly deployed a sophisticated airborne radar to give disaster response agencies a much-needed view of floodwaters that continued to threaten the region.
Extreme winter rains in January 2018 following the Thomas Fire in Ventura and Santa Barbara Counties caused severe debris flows, resulting in significant loss of life and considerable property damage in the town on Montecito, just east of Santa Barbara. NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) airborne radar platform detected changes caused by the debris flows between two images acquired on Nov. 2, 2017, and Feb. 5, 2018. An enhanced image pair (top left) shows disturbed areas in orange.
New Orleans and surrounding areas continue to sink at highly variable rates due to a combination of natural geologic and human-induced processes, finds a new NASA/university study using NASA airborne radar.
