Balancing Act: Can Precariously Perched Boulders Signal New York’s Earthquake Risk?

Long ago, melting glaciers dropped giant boulders onto surfaces in the New York City exurbs, and many seem to remain in their original, delicately balanced positions. Can they be used to judge the maximum sizes of past earthquakes?

Looking for the Origin of Slow Earthquakes in the Guerrero Gap

We are underway on our 48-day long expedition offshore of the west coast of Mexico near Acapulco, where the young Cocos oceanic plate dives beneath the North American plate.

Tea Gardens to the Rescue

We switched to deploying our equipment for imaging faults and the structure beneath the surface to tea gardens to get away from power lines and buried the cables to protect them from gnawing foxes.

Dealing With Rain and Rats

As we continued our geophysical measurements, we had to deal with heavy rains, flooding fields, and rats and foxes biting our cables. Many cables were broken soon after sunset, ruining the measurements.

Fieldwork in Bangladesh During the End of Ramadan and Eid Festival

We have come to in Bangladesh in the pre-monsoon heat to better image the active faults beneath the surface using electromagnetic instruments. We are using the fallow fields from the just-harvested rice crop for our sites.

A Slow-Motion Section of the San Andreas Fault May Not Be So Harmless After All

The central section of the great fault spanning California, thought to be creeping along harmlessly at the moment, has experienced big quakes in the past, says a new study.

Return of the R/V Pelican to Ocho Rios, Jamaica

The expedition discovered stresses along an underwater plate boundary and a record of historic and pre-historic earthquakes, which will shed light on the geohazard risks for Jamaica and Haiti.
