A swarm of earthquakes, many of which were felt locally, were recorded by the Mineral seismograph from April 29 to May 5, 1946. The swarms started again early in June and continued into August. The sharpest quake was of such intensity that campers in the park, thinking Lassen Peak was erupting, left the area during the night. Based on existing faults, renewed hot-spring activity, local reports on felt quakes, and S-P intervals measured on seismograph records from Shasta Dam and Mineral, the source of these shocks appears to be in the Warner Valley section of Lassen Volcanic National Park.
