Recently the science community has developed a new way to image the ground displacement from earthquakes.  It's called  Synthetic Aperture Radar Interferometry, or InSAR for short.  In fact NASA has recently signed an agreement with the Indian Space Agency to fund the launch of a radar satellite for earthquake and climate studies.

The European Space Agency ESA has had such radar capable satellites for years.  One of these satellites, Sentinel-1, recorded and processed this image of the Napa earthquake.  The earthquake is represented by the butterfly-shaped pattern at upper right.  The San Francisco Bay can also clearly be seen.

On the behalf of those images, they can aware people about the circumstances which they can face in future.

This is the best systematic researcher and extremely supportive for proofread my essay about different quakes. After read your article I was acknowledge Earth shudders are caused by the cooling impact from the focal point of the earth and gas weights causing development of the plates or hard surfaces of shake to move to discharge the weight.

this is the first-rate systematic researcher and extraordinarily supportive for proofread my essay approximately one-of-a-kind quakes. After examine your article i used to be well known Earth shudders are as a result of the cooling effect from the point of interest of the earth and gas weights inflicting improvement of the plates or difficult surfaces of shake to transport to discharge the burden.
