The Northeastern part of the present-day Qinghai-Tibet region had a higher elevation than the Southwestern part until the earliest Miocene, i.e., circa 23 million years ago. Thereafter, two phases (12-8 and 5 million years ago) of intensive differential tectonic uplifting led to a significant geomorphologic reversal, resulting in the Southwest/Northeast tilting of the Qinghai-Tibet Plateau as seen today.

 | Death Valley may be known by its three superlatives: hottest, driest, and lowest - as in temperature, rainfall, and elevation in the United States. But it was the flow of water through the National Park that attracted Boston College Asst. Prof. of Geology and Geophysics Noah P. Snyder to the desert of eastern California. ...> Full Article |
Earthquakes occurring at the edges of tectonic plates can trigger events at a distance and much later in time, according to a team of researchers reporting in today's (Jan. 31) issue of Nature. These doublet earthquakes may hold an underestimated hazard, but may also shed light on earthquake dynamics.

 | A reversal of tectonic plate motion between Acapulco and Mexico City in the last half of 2006 probably didn't ease seismic strain in the region or the specter of a major earthquake anticipated there in the coming decades, says a University of Colorado at Boulder professor. ...> Full Article |
 | Perhaps it was just a matter of sympathy, but tremors rippled the landscape of Vancouver Island, the westernmost part of British Columbia, in 2002 during a major Alaskan earthquake. Geoscientists at the University of Washington have found clear evidence that the two events were related. ...> Full Article |
