The application of matching pursuit spectral blueing in post-stack seismic frequency enhancement

Scientific Reports
The calculation of the spectral blueing operator in the traditional spectral blueing method has singularity, which leads to poor performance in post-stack seimic frequency expansion. To this end, a frequency spreading technique based on matching pursuit (

Seismic images of the megathrust rupture during the 25th October 2010 Pagai earthquake, SW Sumatra: Frontal rupture and large tsunami

The Mentawai segment of the Sumatra subduction zone is locked and likely to produce a large earthquake in the near future. A part of this locked zone ruptured on 12 September 2007 producing twin earthquakes of Mw = 8.5 and 7.9.

Seismic structure of the continental margin of French Guiana: implications for the rifting and early spreading of the equatorial Atlantic [PDF]

, 2007
Recent studies of passive continental margins suggest that the rifting process produces a variety of structural styles. The along-strike continuity of these rifted margins is punctuated by significant lateral offsets, known as transform margins.

Longitudinal combined seismic mitigation systems and optimal control for long span triple-tower suspension bridges

Advances in Bridge Engineering
Compared with the two-tower suspension bridge, the seismic response of the middle tower is crucial for the seismic design of triple-tower suspension bridges. A finite element model was developed for a suspension bridge.
