ALT Satellite composite colour image over the city of Quito, capital of Ecuador, showing the grey colours of the urban landscape amongst the green vegetated areas of the surrounding hills, mountains and volcanoes.
ALT Screenshot of the web portal interface for displaying and downloading subsidence data across the country of Iran. Download from https://comet-subsidencedb.org/ Data is from Sentinel-1 SAR imagery processed to produce timeseries of ground deformation from 2014 to present.
ALT The Major Active Faulting of Afghanistan (red lines from the Global Earthquake Model Active Fault Database) overlaid on mosaic satellite imagery (GoogleEarth) shows the tectonics dominated by the large strike-slip faults of Herat and Chaman which run close to major population centres of Herat and Kabul (white circles).

ALT Image generated from satellite radar showing the offsets from the 2021 May Qinghai earthquake indicating where the fault rupture broke the surface and offset the ground by a couple of metres. The fault rupture is almost 160 km long, and is a single trace along most of its length except in the East where there are two strands.
ALT Satellite radar image of the ground surface offsets from the Qinghai earthquake showing the metre scale displacement of the earths surface dues to this big earthquake.
