The Global Navigation Satellite Systems (GNSS) is a network of satellites providing positioning and timing to ground receivers, which provide a fairly precise measure of any movement.

There are several ways to measure movement of the ground due to an earthquake.

Vulnerability is the propensity to be adversely affected by a disaster. Exposure is the presence of people, ecosystems, and infrastructure in places that could be adversely affected by a disaster. Socioeconomic data help assess the exposure and vulnerability of a community to a disaster.
