| Abstract | Mt. Hood, in north-central Oregon, has experienced 13 M ≥ 3.0 earthquakes since 1980. 1812 earthquakes that range in magnitude from -1.1 to 4.5 have been recorded in the region during the same time frame. This paper analyzes four of the larger earthquakes to provide moment tensor solutions and relocated depths. Moment tensor analysis reveals that the larger earthquakes are located on dominantly right-lateral, steeply dipping, normal faults that strike NW-SE. An analysis of the Mt. Hood earthquake catalog reveals a sinusoidal pattern to seismicity that repeats approximately every 8-10 years. This cyclical pattern persists when the data set is constrained to view only magnitude 1+ and 2+ events. |
