Normal seismic activity with numerous tiny earthquakes continues to occur at the southern and western parts of the caldera as well as under Mammoth mountain. There are no signs of a possible eruption in a near future.
Sunday, Mar 31, 2013
Some felt earthquakes have occurred recently along the southern boundary of Long Valley Caldera, the latest a 3.8 magnitude quakes yesterday. This is not unusual for the volcanic system and does not mean any volcanic eruption should be expected in a near future. The alert status remains green (normal).
