Mapping Ground Displacement from the California Earthquakes
The Map Room
This interferogram shows the ground displacement caused by last week’s earthquakes in southern California. Produced by NASA’s Jet Propulsion Laboratory, it’s based on synthetic aperture radar (SAR) images from JAXA’s ALOS-2 satellite taken both before (16 April 2018) and after (8 July 2019) the earthquakes.
OSM Coverage & Population Density
Maps Mania
Disaster Ninja is a map of global population density correlated to OpenStreetMap density. It shows the number of OpenStreetMap objects mapped compared to the local population density. The map can therefore be used to quickly identify populated locations around the world which have not been fully mapped on OSM.

The change in the way this freshwater is stored has had a measurable effect on water availability in the small villages that populate the downstream region.
