This month A Green Space – A Green Earth focus on disaster mitigation and early warnings and how space based Earth observations contributes to safe-guard lives and property.
New satellite techniques such as InSAR complement GPS in unraveling in fine details crustal movements of the Earth. ESA's GOCE gravity measurements from space will add knowledge to our understanding of sub-surface movements leading up to earthquakes. Through observing Earth from space before, during and after earthquakes we improve disaster mitigation and early warnings.

Haiti Earthquake & Earthquake Science in "The Ring of Fire". (see 2d video in playlist) We take a closer look at the science of Haiti earthquake of 12th February 2009 - as well as other earthquakes. For the first time here on GSGE we interview leading experts;
Prof. Timothy Dixon from Geodesy Lab at University of Miami: published an article already back in 1998 revealing the risks of earthquakes in Haiti. He works with both Paul Mann from University of Texas who in 2008 confirmed that the risks were eminent, and Eric Calais, Purdue University who manages the GPS network that monitor tectonic plate movements in Haiti. These three groups have sent geodesists with GPS equipment, while also maintaining a blog. See below.
Ass. Prof. William Hammond from University of Nevada in Reno: Explains how they use GPS to monitor plate movements - and earthquake swarms.
Dr. Amir Kaynia from the International Centre for Geohazards in Oslo, Norway: Talks about the difference between predictions and early warning and discuss other geohazards connected to earthquakes.
