Cropped satellite image of HispaniolaNASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar, aboard a modified NASA Gulfstream III aircraft, will study geologic processes in Hispaniola following the Haiti earthquake. NASA’s flights will help scientists better assess the geophysical processes associated with earthquakes along large faults and better understand the risks, said Paul Lundgren of the Jet Propulsion Laboratory in Pasadena, California, the principal investigator for the Hispaniola overflights.

GEO establishes Haiti supersite

Image of full GEO logoThe Group on Earth Observations GEO established a supersite in response to the fatal Haiti earthquake from January 12 (http://supersites.unavco.org/haiti.php). Satellite data from different sensors and various derivates are collected and provided on this website including SAR data, topography data, visible and infrared imagery, GPS data, surface deformation and seismic data. This effort has been made possible by the contribution of national space agencies and data providers worldwide such as NASA, ESA, JAXA, DLR, USGS and others.

Image of a C-17 Globemaster III delivering humanitarian aid to Haiti via parachute drops. The earthquake in Haiti, a human tragedy on the ground, has brought requests to remote sensing and geosciences experts from humanitarian relief agencies for help in mapping the disaster. This article, originally published 19 January 2010 by Der Standard, quotes Earthzine Deputy Editor Christoph Aubrecht, who is a remote sensing and geoinformation scientist at the AIT Austrian Institute of Technology working on geospatial issues of disaster management. Aubrecht translated and adapted this article for Earthzine.
