Aftershocks of the Sendai earthquake
On a map of global earthquake activity, Japan rather stands out right now: a pulsing boil of seismic activity that all but drowns out the shaking in the rest of the world. As of a few hours ago (5pm Central … Continue reading
Shaking in Christchurch boosted by seismic lensing?
Even taking into account how close the rupture point of Tuesday’s earthquake was to Christchurch, the intensity of the shaking – and the amount of damage that the city suffered as a consequence – seems to be very high for … Continue reading

Why are we getting an extensional earthquake at a convergent plate boundary? Continue reading
Yellowstone: what lies beneath
The best evidence yet that the Yellowstone hotspot is the result of a mantle plume – one that had to burn through a subducting slab to get to the surface. Continue reading
