地面微地震监测采集到的微地震信号通常能量微弱，信噪比低，如何提高微震数据的信噪比是数据处理的难题.Shearlet变换是一种新型的多尺度几何分析方法，具有敏感的方向性和较强的稀疏表示特性，能起到很好的随机噪声压制效果.由于地面微震数据的有效信号大多被淹没在噪声中，基于传统阈值的Shearlet变换（the traditional threshold-based Shearlet transform...

In this paper we are introducing analytical 3D views as a means for effective and understandable information delivery, using virtual
globes and the third dimension as an additional information carri...
Scientific overview and historical context of the 1811-1812 New Madrid earthquake sequence
New Madrid earthquakes intraplate historic
2015/9/14
The central and eastern United States has experienced only 5 historic earthquakes with Mw 7.0, four during the New Madrid sequence of 1811-1812: three principal mainshocks and the so-called 玠awn after...
The 11 May 2011 earthquake at Lorca (SE Spain) viewed in a structural-tectonic context
earthquake at Lorca structural-tectonic context
2014/12/31
The Lorca earthquake of 11 May 2011 in the Betic Cordillera of SE Spain occurred almost exactly on the Alhama de Murcia fault, a marked fault that forms part of a NE-SW trending belt of faults and thr...
Anomalous width variation of rarefactive ion acoustic solitary waves in the context of auroral plasmas
rarefactive ion acoustic solitary waves context of auroral plasmas
2009/11/11
The presence of dynamic, large amplitude solitary waves in the auroral regions of space is well known. Since their velocities are of the order of the ion acoustic speed, they may well be considered as...
Fluid-driven seismicity in a stable tectonic context: The Remiremont fault zone, Vosges, France
Fluid-driven seismicity in a stable tectonic context The Remiremont fault zone Vosges France
2014/4/15
Some relocated seismic events, which have small magnitudes(ML < 4.8), are found to align along a 40 km-long fault zone flanking the southern Vosges Massif to the west. It joins to the south with the e...
