Her 50 simulations used variables spanning realistic values for the depth of the slip, and had randomly placed hypocenters and sticky points. (sciencedaily.com)
Yong Zhang from the GFZ German Research Centre for Geosciences and the China Earthquake Administration and colleagues begin this process by confirming a new hypocenter for Lushan. (sciencedaily.com)
Sato et al. (p. 1395, published online 19 May) describe the huge displacements from ocean bottom transponders — previously placed directly above the earthquake's hypocenter — communicating with Global Positioning System (GPS) receivers aboard a ship. (science.sciencemag.org)
