• Magnitude 4.5 Earthquake felt in Reno and Lake Tahoe region, Nevada and California
  A magnitude 4.5 earthquake was recorded Thursday, at 1:54 AM PDT on June 3, 2004, in the Reno - Lake Tahoe region, Nevada and California. It was located at 39.334 N, 120.007 W, with a preliminary depth of 8.6 kilometers (~ 5 miles). This location is approximately 6 miles (10 km) north of Kings Beach (and the north shore of Lake Tahoe), and nearly on the Nevada - California state line. We located five minor foreshocks, with the largest being a (preliminary) magnitude 2.7 foreshock at 1:25 AM. We are recording a large number of aftershocks. The largest so far was at 4:16 AM (preliminary magnitude 1.5).
  The earthquake was felt as light to weak shaking throughout the Reno and Lake Tahoe region.



• Magnitude 2.4 Earthquake in Reno, Nevada
  A magnitude 2.4 earthquake was recorded Saturday, at 6:57 AM PDT on April 10, 2004, in Reno, Nevada. It was located at 39.507 N, 119.767 W, with a preliminary depth of 8.6 kilometers (~ 5 miles). This location is approximately under the Reno International Airport. The earthquake was felt by many residents of Reno/Sparks. No aftershocks have been located.

Max-Log solution to inverse problems

ABSTRACT: We seek a positive function whose integrated products by specified nonnegative constraint functions take given positive values. A non-linear solution to this linear inverse problem is proposed and its properties in response to increasing information or conflicting information are investigated. Our solution is based on the maximization of expected logarithms with respect to an arbitrary fully supported probability measure. This working measure plays the role of an initial guess of the solution and controls a Monte Carlo which we derive from our sequential extension of the Exponentiated Gradient (EG) algorithm of On-Line Learning theory. The approach bears superficial similarity to entropy methods but is in general different.

1/24/03 - Seminars are being given by candidates for a new position in the math department and may be of interest to the seismological community. These candidates are applying for a position focusing on PDE solutions and it is likely that geophysics students will find this new position a valuable resource. Each seminar is in room 634 of the Ansari Business Building.
