Suggested best practice for seismic monitoring and characterization of non-conventional reservoirs

General awareness of induced seismicity and gas leakage related to energy reservoir exploitation has been on the rise for several years (McGarr, 2002; Davies et al., 2013). This includes events from short-term Huid injection for reservoir simulation (Giardini, 2009; Atkinson, 2016), Long term hydrocarbon extraction (Van Thienen-Visser and...

Geodynamics of the Gulf of California from surface wave tomography

The Gulf of California, which forms part of the Pacific-North American plate boundary, is an ideal place to investigate upper mantle dynamics in a continental rifting area. With 19 seismic stations located around the gulf, the NARS-Baja experiment (2002-2008) was designed to image its crustal and mantle structure. Here we present results of a...

Reply to comment by S. Crampin on 'global anisotropic phase velocity maps for higher mode Love and Rayleigh waves'

We thank Stuart Crampin for his interest in our recent paper but respectfully disagree when he argues that our measurements are not appropriate for inferring mantle anisotropy. The approximations we made are common and perfectly acceptable for the considered frequency band. The comment ignores a large part of the literature which investigated...
