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
"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
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. |

The Sumatra-Andaman earthquake of December 26,
2004, was one of the worst natural disasters in recent
memory, mostly on account of the devastating tsunami that
followed it. A group of geologists and geophysicists, including
scientists at the California Institute of Technology, has
delineated the full dimensions of the fault rupture that
caused the earthquake.
