In Fontana this morning...4.4 I think it was. :eek: ......no injuries or damages......
that is the home of the California speedway if you didn't already know..hope the track is ok.....
 
Hope it doesn't create an occurance like there was at Martinsville with Gordon. :)
 
4.4 is just a little one, I've slept through a couple of 5.0 quakes
 
I don't think I've slept through a 5.0 unless the epicenter was 25 or so miles away. I might have slept through a 4.4 though!! :) But, then again, I've felt 2.0!! But the epicenter was quite close when I did. Just depends on how far away, how deep and whether or not it was a vertical or horizontal shake.

Now, I have a question for anyone who has lived in earthquake prone areas. I spent my teenage and early adult years out here in Southern California......then I moved back here about 8 years ago. A total of about 23 or 24 years. I've been in a number earthquakes.........mostly minor but I do remember the Sylmar quake in the late 60's (I think it was in the 6.5 range.......I wasn't here for the Northridge quake of the mid 90's). But what I wonder every time I feel one is, if the quake actually makes noise. I swear I hear a rumbling like thunder........different from the creaking and groaning of walls and rattling of dishes or windows that I also hear. I've asked a lot of people and about half say they hear it too......but the other half say they don't. I wonder if it's just something my mind hears due to the jolting and rocking I'm feeling........in other words my imagination. Or do they actually make the noise I hear. I don't hear it with quakes under the 3.0 range.
 
DEW, I think you are right. I know the Northridge quake was pretty scary.
And yes, I was in bed, and the noise woke me, not the shakin; that started after I got up to see what was making the noise. I had a 55 gallon aquarium in the living room. LOL All I could think of was, "OH NO, Don't fall over!!!!"
I was leaning in that and watching the hanging lamp over the recliner swaying wildly back and forth. Two hard jolts almost knocked me off my feet. :eek:

Yeh, I think there is a low rumbley noise too. :cool:
 
We live close to a fault line here in W. Tn. It's call the New Madrid fault. There hasn't been an major earthquake in 200 years. We have small ones all time at the race of about 2-3 hundred a year. That last major one was in 1811. It was like a 9.5 and changed the course of the Mississippi river and rang church bells im Boston Mass. Hope nothing ever happens like that again around here. :(
 
We experienced a shaker along the New Madrid Fault in the middle of the night and the noise is what woke us up (and the dog barking at the noise). I don't know the magnatitude, but it did shift the ridge we live on enough to set the house a bit off kilter. ( by that I mean squeeky doors, little cracks in the wall, nothing that couldn't be fixed easily).

We DID sleep through a tornado that swept through only a/4 mile away and ony found out when a friend called to see if we were OK at 3 or 4 AM.
 
I check that E-quake site and the Mount St Helen's site every day.
Mt St. Helen's has really quieted down. Still steaming some, but rather quiet.
Snow and icicles on the Johnston Ridge cams are pretty.

MOUNT ST. HELENS UPDATE

Current status is Volcano Advisory (Alert Level 2); aviation color code ORANGE

Growth of the new lava dome inside the crater of Mount St. Helens continues, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash. During such eruptions, episodic changes in the level of activity can occur over days to months. The eruption could also intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.


Potential ash hazards:Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim today would chiefly drift west-northwestward.


Recent observations: The volcano is shrouded in clouds this morning. New instrumentation packages installed on the dome Friday are transmitting data that will be used to more closely track movement of the north end of the new dome. Seismicity suggests that small rockfalls are occurring from the dome. Such rockfalls may generate ash plumes that drift over the crater rim.
