Ground shaking caused by the sudden release of accumulated strain by an abrupt shift of rock along a fracture in the earth or by volcanic or magmatic activity, or other sudden stress changes in the earth.
An automated system for rapidly estimating the shaking distribution, number of people and settlements exposed to severe shaking, and range of possible fatalities and economic losses. A color-coded alert suggests levels of appropriate response.
