Cracking Los Angeles
Article Abstract:
Los Angeles is caught between the converging tectonic plates of North American and the Pacific, and beneath it there are many faults of differing shapes and sizes. It is complicated to define the motions along such faults and the forces that are released in earthquakes. Walls and colleagues have estimated such motions and seismic risk, concluding that the strike-slip fault beneath Los Angeles could be more dangerous than previously thought.

Seismic imaging of hotspot-related crustal underplating beneath the Marquesas Islands
Article Abstract:
Seismic refraction experiments conducted on the Marquesas Island hot spot reveals a high-velocity material at the lower crustal region of the 15-17 kilometer-thick crust. The seismic velocities suggest the presence of crustal underplating, which is either made of only intrusive or a combination of intrusive and preformed rocks. The amount of this high-velocity material is double that of the erupted volcanic material.
