scientists issue indonesia earthquake warning, stress changes signal risk increase

The above article which appeared in Nature, posses a need for active information on the risk of major earthquakes. Research indicates that a Big earthquake can cause other areas to react (to stress changes) in what is known as remote triggered seismicity. Maybe the Ulster Team can issue the same sort of calculations for other parts of the world whereat a Big earthquake has occurred in the last 5 years and the risk these areas are subject to...

After what has happened (8.7 earthquake) this thread is awesome.

Actually there is no valid scientific reason to assert that a Big Earthquake, B.E.,(Magn > 8.0 Mw) has released all the accumulated stress from a certain area. Most of the B.E.´s are ussually followed by one Major Earthquake M.E., (Magn> 7.0) and several Strong Earthquakes, sometimes in the one or two weeks following the main event, sometimes, years afterwards.
Because of the few, (one) M.E. that followed such a massive B.E. as the 9.0 Mw Sumatra event of 2004 12 26, one could expect worst was to follow... Now we can still wait for more M.E.´s to ad to the total sum of stress release.

On the other hand, this is not always so, as the earth has its own timing, which is very, very slow for us, accelerated humans. Like one second for us is a day or a year for the earth.

There is one interesting lead that is being followed right now. That is, after the Big Sumatra earthquake, there was several volcanoes around the world which fumed their chorus. Off the Ecuador Coast there was a swarm which produced more than forty earthquakes so far, including four strong earthquakes in only seven days. Apart from that, way east in the amazon and matto grosso, two moderate earthquakes showed, maybe, the extent of the shock, since these are locations which seldom have any seismic activity.

All the above would, in fact, erase the "chaos" theory of non relationship in between seismic events and show the opposite way, that of all seismic activity is related to another.
