Friedemann Freund — The Future of forecasting Earthquakes
Friedemann Freund doesn't shrink from taking on the really big problems. His research has elucidated such important phenomena as the fact that rocks under stress behave like batteries that can produce currents deep within the crust of the Earth. These are not piddling currents, either - they can be hundreds of thousand amperes, maybe as large as several million of amperes, sufficient to be measured above ground, and perhaps even from orbit. Understanding this phenomenon and exploiting it could lead to a breakthrough in earthquake forecasting.

In the days leading up to some recent moderate-sized earthquakes, instruments nearby have picked up brief low-frequency pulses in Earth’s magnetic field. A few scientists have proposed that such pulses, which seemed to become stronger and more frequent just before the earthquakes occurred, could serve as an early warning sign for impending seismic activity. Now, a team has come up with a model for how these magnetic pulses might be generated, though some critics say they may have a humanmade origin.

NAPA, Calif. (KGO) — There’s been a lot of talk this week about the need for an early earthquake warning system. The USGS is working on one that could offer a second or so of notice. A Bay Area scientist who works for NASA is working on a different system that he says could warn you about a quake days before it happens. For cities like Napa and Vallejo, which are facing possibly billions of dollars in damage, those extra days could make a world of difference.

Animals may sense chemical changes in groundwater that occur when an earthquake is about to strike. This, scientists say, could be the cause of bizarre earthquake-associated animal behaviour. Researchers began to investigate these chemical effects after seeing a colony of toads abandon its pond in L’Aquila, Italy, in 2009 – days before a quake. They suggest that animal behaviour could be incorporated into earthquake forecasting.

Rare flashes of light that are sometimes seen around earthquakes are not caused by birds, or planes, or UFOs—all of which had been previously used to explain the phenomena known as earthquake lights. Instead, the lights are caused by electrical properties of certain rocks in specific settings, report scientists in a new paper.

A new catalogue of earthquake lights — mysterious glows sometimes reported before or during seismic shaking — finds that they happen most often in geological rift environments, where the ground is pulling apart. The work is the latest to tackle the enigmatic lights, which have been described by eyewitnesses for centuries but are yet to be fully explained by scientists.
