The shaking started at around 3:30 am pst, and have continued throughout this evening. Frequency and intensity seem to be increasing.. Read more: thecount.com...
Intensive monitoring has been ongoing near Mammoth Lakes since 1980, when four earthquakes of at least magnitude 6 struck in a two-day period. David P. Hill, chief of the monitoring efforts, said this week that one reassuring finding is that the cataclysmic eruptions of the past, such as the collapse of the 10-by-20-mile Long Valley caldera 760,000 years ago, are not a prospect now. That eruption was 2,000 times greater than the Mt. St. Helens eruption of 1980. Scientists now believe, Hill said, that an eruption near Mammoth Lakes is not likely to approach even Mt. St. Helens in size.
