    Fine here in San Fernando Valley, but my parents and sister who live near Highland felt it pretty strong.

    I am in Temecula and it was short. Not as strong as some I have felt. My daughter decided to stay downstairs for awhile.

    I have live here all my life, 37 years and I still cannot get used to them. They freak me out every single time.

    :eek:hmy:
    I'm about 15 miles away from the epicenter and it was strong.
    Wow! It rolled and rolled for a while.
    SCARY!

    Hm. Let me look into that - I didn't feel it, but that doesn't necessarily mean much.

    (later)

    Okay, the USGS at http://quake.wr.usgs.gov/recenteqs/Quakes/ci10370141.htm is calling this a light quake, 4.5 on the scale - though there's nothing quite like being right on top of a quake to convince you that it's Armageddon Or Something Like It. The epicenter's 2 km from the San Bernardino city center, evidently. Nobody much south of Temecula seems to have reported shaking, according to the map at http://earthquake.usgs.gov/eqcenter/shakemap/sc/shake/10370141/intensity.html, but there seems to have been shaking as far west as the eastern San Fernando Valley - whew! Not to mention an assortment of smaller quakes in the last hour.

    This all happened after I went to bed.

    So I shouldn't be unnecessarily concerned about my sister-in-law near LA, right?

    Pretty sad when I get my National news on a teacher board!

    I hope you all are okay!

    Wait a minute. So those little yellow boxes mean there were tiny quakes or tremors over the last week?

    Lemon <------ not a quake expert.

    A 4.5 will shake one up, but it is, as these things go, not huge - bear in mind that the intensity scale goes up logarithmically (that is, a quake of magnitude 4 is ten times as strong as one of intensity 3). Once the quakes get up to five-plus, then they're serious.

    Alice, LA is a pretty big place, and the shake map suggests that part of the city will have felt this thing - but it would surprise me to hear of any damage within the city limits to anything that wouldn't have been damaged by a door slamming anyway.

    lemon, the red boxes are for quakes within the last hour; the blue boxes are quakes within the last 24 hours; the yellow boxes are quakes within the last week. Magnitude 3 quakes are relatively routine, unless they're right under one (there was one three or four years ago with an epicenter about ten miles from here; it sounded and felt a bit like a shotgun blast); magnitude 4 quakes get a person's attention; magnitude 5-plus to six send people scurrying for the doorways; magnitude 7 and over tend to do bad things to the utilities and the roads, though not as bad as they did before the advent of reinforced masonry.

    You're welcome.

    Sometimes I think I can't so much as raise an eyebrow without teaching.

    So happy that I moved from California last July! I remember the Northridge earthquake....ever since any earthquake that would occur at night would keep me up all night.:eek:hmy:

    I was just starting to close up the library in Irvine and I was helping a student try to figure something out w/a computer...so my mind was totally focused on something else and I didn't feel a thing! It must have been one of the really short ones.

    There was an afterschock (well there may have been several) but one strong enough that we felt in the 8 o'clock hour...I was at home then (closer to where the EQ occurred) and I didn't feel it but the rest of my family did! What's weird about all that, I am normally the one to always feel them!!

    Glad all is well with everyone in the area! :)

    The fun thing about consulting the map Dave posted in its native habitat (so to speak) is that, when you click on one of the boxes, it opens a window with information about the quake.

    The red lines are faults or fault systems, including the justly notorious San Andreas (which is, by the way, the subject of a grand stinker of a Bulwer-Lytton Award winner some years ago: set in Old California, the supposed first paragraph described a young priest in flagrante delicto with a native maiden and the, um, climax coinciding with an earth tremor, causing the terrified clergyman to exclaim, "Can this be my fault? - and his name was, of course, Andreas).

    I spoke to my sister in law. They're fine, no damage or anything.

    They lost a LOT in the '94 (??) Northridge quake. So they still get jittery when the room starts to shake. She said, as a native New Yorker, it's still the most frightening thing, one she'll never get used to.

    Alice, I don't know anyone who doesn't get jittery when the room starts to shake.

    The native is the one whose jitters stop soon after the shaking does.

    Yeah, I'm guessing my sister in law is still shaking a bit, and she's been in the LA area for a good 30 years.
