Hi All,

Even this year's Fall AGU Conference is being changed by the Alaska earthquakes. Papers are being accepted to 11/13 for those who wish to make presentations on this event.

Here's the data from the AGU Site:

Late-Breaking Seismology Session! The October-November 2002 Earthquake Sequence on the Denali Fault, Alaska

The Denali fault is perhaps the most significant crustal fault in Alaska. It is seismically active, has a record of Holocene offset, and arcs through Alaska, slicing the rugged Alaska Range and bounding the precipitous north face of Mt. McKinley, the highest peak in North America. An Mw 6.7 earthquake on the Denali fault on 23 October 2002 was followed by an Mw 7.9 earthquake on the same fault on 3 November 2002. The latter earthquake is one of the largest strike-slip earthquakes ever to strike the United States. Prior to this sequence, the largest historical earthquake on or near the Denali fault occurred in 1912. The seismic behavior of the Denali fault, like the northern and southern segments of the San Andreas fault in California, is characterized by infrequent large earthquakes. This session will present preliminary findings on the earthquake seismology, aftershocks, deformation, and geologic effects of the earthquake. The session also welcomes contributions that relate to historical seismicity, deformation, and paleoseismology of this part of the fault. This session is cosponsored by the Geodesy and Tectonophysics sections.
