Mt. Fitzherbert
« March 2008 | Main | May 2008 »
RECENT OBSERVATIONS: One earthquake was located by the Pacific Northwest Seismograph Network over the last week, and other monitoring data showed no changes. Appreciable snowfall on Wednesday and Thursday re-established the 20-plus-foot-deep snow drift in front of the webcam at the U.S. Forest Service's Johnston Ridge Observatory, blocking views of the crater. Forecasted warmer weather should cause the drift to shrink some over the next several days.
RECENT OBSERVATIONS: Monitoring data from field sites showed no change during the past week--the volcano remains quiet. Recent increases in seismicity on some crater instruments is caused by increased glacier movement during periods of warm weather rather than by volcanism.
