Joint full waveform inversion and source localization of virtual and actual passive source seismic data [PDF]
Scientific ReportsFull waveform inversion (FWI) using passive seismic data offers potential advantages for obtaining deep subsurface structural information. However, its application depends on a reliable background model and accurate source locations. Here, we introduce a

Gas slug ascent through changes in conduit diameter : Laboratory insights into a volcano-seismic source process in low-viscosity magmas. [PDF]
, 2006 Seismic signals generated during the flow and degassing of low-viscosity magmas include long-period (LP) and very-long-period (VLP) events, whose sources are often attributed to dynamic fluid processes within the conduit.We present the results of ...

The trigger mechanism of low-frequency earthquakes on Montserrat. [PDF]
, 2006 A careful analysis of low-frequency seismic events on Soufrie`ere Hills volcano, Montserrat, points to a source mechanism that is non-destructive, repetitive, and has a stationary source location.

Seismic anisotropy in siliciclastic reservoir rocks [PDF]
, 2006 The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements
