Sentinel system pictures Napa quake
C Frank0 stashed this in San Francisco
Europe's new multi-billion-euro Sentinel programme has returned its first earthquake analysis.
The EU satellite system has pictured how the Earth moved when theMagnitude 6.0 tremor hit California's wine-producing Napa region last month.
Scientists will use the figure, called an interferogram, to trace precisely the extent of the fault rupture.
In the past, this type of analysis has been very time-consuming, but the Sentinel project will now automate it.
Interferograms that once took many weeks, even months, to produce should in future come out within days of a big quake.
