    There is a very large amount of energy being built up just north of Los Angles. That swath just south of the mountains has been way too quiet for the last few months.

    P.G. Sharrow, hum?
    Of additional concern, the area south of that has been very avtive, progressing north.

    That it’s also the chunk most likely to let go (most ‘due’) is also a worry:

    http://pubs.usgs.gov/gip/earthq3/when.html

    Geologic studies show that over the past 1,400 to 1,500 years large earthquakes have occurred at about 150-year intervals on the southern San Andreas fault. As the last large earthquake on the southern San Andreas occurred in 1857, that section of the fault is considered a likely location for an earthquake within the next few decades. The San Francisco Bay area has a slightly lower potential for a great earthquake, as less than 100 years have passed since the great 1906 earthquake; however, moderate-sized, potentially damaging earthquakes could occur in this area at any time.

    The ring of fire is off again…

    Several people have been injured by hot ash as Indonesia’s most volatile volanco begins to erupt.
    A reporter near Mount Merapi witnessed by to 20 people being taken away for treatment.

    Video that claims to be of the eruption:

    but looks like it’s mostly steam and clouds to me…

    The expected pattern is that we ought to have increasing quakes and volcanoes (given the prior pattern in grand minima). I’m torn between a desire to see the pattern proved again and a desire to not have the results of the proof…

    And they had a 7.7 yesterday…
