Japan won’t stop shaking. One month after the March 11 earthquake and tsunami, the nation rode out yet another powerful aftershock Monday, the second in four days. This one rattled buildings in Tokyo and briefly cut power to the damaged nuclear plant in Fukushima.

 

With soldiers still looking for the bodies of thousands of people who vanished in the killer wave a month ago, Japan is coping with the painful reality that it sits in a seismic bull’s-eye.

A new calculation by American and Japanese scientists has concluded that the March 11 event may have heightened the stress on faults bracketing the ruptured segment of the Japan Trench.

“There’s quite a bit of real estate on which stress has increased, by our calculations,” said U.S. Geological Survey geophysicist Ross Stein. “The possibility of getting large, Read more…

Christchurch torn by entirely new fault

A new threat of landslides has emerged near to the epicentre of the quake, where boulders loosened by the tremor have already killed two and crushed homes. An aerial survey by scientists found no surface trace of the fault, which is centred southeast of Christchurch. But the expedition found worrying evidence of slips on the crest of the Port Hills, and above Lyttelton, Rapaki and Sumner. Geologists would place monitoring stakes in the hills to measure whether the landslides were creeping towards populated areas.

Early investigations have suggested that the shallow earthquake was an aftershock of the September quake in Darfield, but did not come from the same faultline. GNS Science natural hazards platform manager Kelvin Barryman said tests indicated it occurred on a “blind” or unknown Read more…
