Caltech Today: Tracking
Earth Changes with Satellite Images
For the past two decades, radar images from satellites have
dominated the field of geophysical monitoring for natural
hazards like earthquakes, volcanoes, or landslides. These
images reveal small perturbations precisely, but large changes
from events like big earthquake ruptures or fast-moving glaciers
remained difficult to assess from afar, until now.

 Caltech Today: Earthquake
Season in the Himalayan Front
Scientists have long searched for what triggers earthquakes,
even suggesting that tides or weather play a role. Recent
research spearheaded by Jean-Philippe Avouac, professor of
geology and director of the Tectonics Observatory at Caltech,
shows that in the Himalayan mountains, at least, there is
indeed an earthquake season. It's winter.

PADANG, Indonesia: Experts warn 'big one' may yet hit Indonesia (pdf)
"No one can say whether it will be in 30 seconds or
30 years," he [Kerry Sieh] said. "But what happened
the other day, I think is quite possibly a sequence of smaller
earthquakes leading up to the bigger one."

STRAITS TIMES: Singapore
Monster Quake Could Hit Soon (pdf)
The earthquakes off Sumatra could portend a monster quake,
and it could hit soon. Caltech's Kerry Sieh says the Mentawai
patch, an area of strong resistence just southwest of Padang
Sumatra, is "close to no longer being able to stand
the strain" of continuing pressure buildup.

Mysteries: What Happens Inside an Earthquake?(pdf)
"...when faults do move, something is missing -- there
is little to no evidence of the extremely high levels of
friction and melting that would be expected to follow above
ground when two giant rocks slid against each other. "There
are many reasons to believe that something exotic is happening," said
Caltech geophysicist Tom Heaton..."
