Earthquake and earthquake induced disasters caused huge economic loss and casualty. Earthquake disasters are becoming the mainly part of catastrophes recently. Although earthquake can not be predicted exactly until now, we can get the magnitude and location for a certain earthquake event quickly after it happened based on the earthquake monitoring network and quick response for a disaster event can effectively reduce casualty and economic loss. In 2005, we started to develop a Global Earthquake Disaster Alert System (GEDAS) for international relief affairs to response quickly for earthquake disaster. This paper describes the application of global scale data, such as VMAP0, Geocover, Landscan etc., in GEDAS.
