Earthquake Swarms – Bay Area – Trouble Brewing?

posted by Jack

Could this be the precursor to the big one? I sincerely hope not, but we know the San Andreas could let go anytime. I’m posting this in the hopes that folks will take reasonable precautions as best they can if the worst should happen.

“Looking in that general region, I’m counting 55 quakes just in the last week,” said Amy Vaughan, a geophysicist with the Geological Survey.

A series of small earthquakes shook the area around Danville, including one with a 3.3 magnitude.

A cluster of small earthquakes continued to shake the Danville area into Friday afternoon, measuring as strong as magnitude 3.5, slowing BART trains, but causing no significant damage, authorities said.

As of 1 p.m., the U.S. Geological Survey had reported 16 quakes in the area, with five of them above magnitude 2.5. The 3.5-magnitude temblor happened at 12:19 p.m. Friday near Diablo, a wealthy community northeast of Danville.

And this by Martin Nascimento,

“When BART receives reports of earthquakes, it stops trains until it can get information from the Geological Survey.

If the magnitude is lower than 3.0, trains can start running under automatic controls. If it’s higher than 3.0, operators run trains at low speeds, under manual control, for about five minutes while conducting visual track inspections.”

A 2.8 earthquake at 12:21 p.m. caused BART to halt trains briefly, transit officials said. A 5:53 a.m. quake also led to a 10-minute delay that affected the morning commute.

The quake cluster mostly consisted of shakers too small to feel, but a 3.3-magnitude event struck at 5:28 a.m. about 1 mile northwest of Danville, according to the Geological Survey. In the hours before, quakes of 2.8 and 2.7 shook the area.

    Off topic.

    FYI – Mark Levin’s show “Life, Liberty and Levin” begins on Fox News tonight at 7pm and repeats at 10pm. It will be a weekly Sunday night show.

    Watched a bit of it and the one thing I liked was the calm debate, no one jumped on the others comments or talked over them in the segment I watched.

    I am so sick and tired of the narrators (on any political show) allowing guests to yell and argue. Also it is bothering when narrators inject themselves over the guest, you can be passionate about something, but without respect for the others, it just turns into a unbridled yelling match. And the whole point of the interview is lost and becomes a waste of veiwing time.

    If Levin continues with this (his) type of format, he will have my viewership .

      He commented on his radio show that the format would be calm Levin and not the bombastic one.

      His libertarian economist was interesting as was hearing about their long relationship. Levin presents himself as a hardcore conservative and I found their respect for each other note worthy.

      There are certain commentators I won’t watch any more. I’m not wasting my time listening to them repeat for the millionth time bloviating about themselves. Nor will I watch shows where individuals constantly talk over and constantly interrupt. Juan Williams is the worst with his higher pitched voice is able to drown out others. And his remarks are so uninformed he’s an embarrassment to himself and his party. Watch Brit Hume shake his head and roll his eyes at William’s remarks. It’s hilarious.

      Anyway, I’m looking forward to seeing more of his shows and like his low key format.
