An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Radiated Energy from the 16 October 1999 Hector Mine Earthquake: Regional and Teleseismic Estimates [PDF]
Bulletin of the Seismological Society of America, 2002 The amount of seismic energy radiated from an earthquake is a key macroscopic parameter for understanding the physics of earthquakes. To resolve the important details of the earthquake process, we require more accurate estimates of energy than are currently available.

Seismic Radiation From Simple Models of Earthquakes [PDF]
, 2006 We review some basic features of shear wave generation and energy balance for a 2D anti plane rupture. We first study the energy balance for a flat fault, and for a fault that contains a single localized kink.

Seismological Aspects of the December 2004 Great Sumatra-Andaman Earthquake [PDF]
, 2006 The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1,200–1,300 km. The seismic moment, M0, determined with a finite source model, was 6.5×1022 N-m, which corresponds to Mw=9.18.
