Remotely triggered earthquakes

[1] The farther one gets from the initiating earthquake in both space and time, the more difficult it is to establish an association.

Remote earthquakes, however, are in a position to disturb this critical state, either by shifting the stresses statically, or by dynamic change caused by passing seismic waves.

[2] This event reinforced the idea of remotely triggered earthquakes, and pushed the hypothesis into the scientific mainstream.

[3] There is scientific evidence for a "long reach", mainly in the form of discrete element modelling used in the mining industry.

If rock is modeled as discrete elements in a critical state, a single disturbance can influence a wide area.
