Again, the seismic station in Utah.
I have never seen a chart with 3 major eqs in one day.

IS this the 3rd one in 24 hours??
This is the third major quake today.
Earthquake Ping List plus a few others just for this ping. Please FReepmail me if you would like to be added to or removed from this list.
Good grief. What’s going on over there? Is it normal to have so much activity like this in such a short period of time?
OH MY...3rd today and all seem to be rather large...bet the people are freaking out...

Earthquake Summary
The following is a release by the United States Geological Survey, National Earthquake Information Center:
An earthquake occurred about 165 km (105 miles) SSW of Padang, Sumatra, Indonesia or about 345 km (215 miles) WNW of Bengkulu, Sumatra, Indonesia or about 900 km (560 miles) WNW of JAKARTA, Java, Indonesia at 9:35 PM MDT, Sep 12, 2007 (Sep 13 at 10:35 AM local time in Indonesia).
The magnitude and location may be revised when additional data and further analysis results are available. No reports of damage or casualties have been received at this time; however, this earthquake may have caused substantial damage and casualties due to its location and size.
Looks like that country gets quite a few.
The area is a very active seismic zone but it is unusual to have this many major quakes in this short a period of time.
See a map of the Seismic History of the area here.
And a 6.5 just hit.

Agree. Prayers up for the people in the area.
Understatement.
No need for caffiene.
Is that a 4th?
These three major quakes all occurred in a period of around 16 hours.
Thanks Lokibob.
Thanks nicmarlo. Just a really bad day for that area.
I’ll never forget that picture from a few years back of all those dead, bloated bodies as far as the eye could see. Nearly 1/4 million people died from that event if I recall correctly.
If I lived there I would be absolutely terrified right about now.
From living in So. Calif. for quite awhile, I know that when there’s a large quake, there can be many large aftershocks following them...
Thank you Global for posting the info!
Yeah...looks like; I hope that, even though the epicenter’s not very deep, there’s no large loss of life...it’ll depend on the kinds of structures near there...
I’m seeing in triples! Just finished reading throught the previous two threads... Haven’t seen any pictures - wonder how much damage this is doing there...
3rd within 24 hours is very strange. Prayers for these poor people.
I was just gonna say the same thing.no pics
I live in Southern California too and went through the Northridge quake.
The term "aftershock" is not scientifically significant other than it describes an earthquake which occurs after another earthquake nearby.
Basically the movement of earth's plates is what causes an earthquake. Several earthquakes occuring in a certain period of time simply means that the plates are continuing to move.
The Northridge quake (1971?) was my “welcome” to earthquakes, after moving to CA from NY (to where I’ve returned) as a kid.
That was something.
Unbelievably sad news. Thanks for the quick work on these threads.
The 8.4 quake earlier today was 30 km deep, and both the 7.9 quake, and this 7.1 quake are both 10 km deep. All three are considered shallow. The damage is usually much greater during shallow quakes.
I know. But, if there’s not lots of skyscrapers or poorly built homes in the vicinity....they’ll have less loss of life.
Just got another email it has been revised to 7.1 but it can be revised again ya know. ; )
PADANG: A powerful earthquake shook western Indonesia for the second straight day Thursday, collapsing buildings in a coastal city and triggering tsunami alerts around the region. The jolt could also be felt in neighboring Singapore, causing high-rises to sway.ooops...don't sound too good, bd.The Pacific Tsunami Warning Center in Hawaii warned the new 7.8-magnitude quake had the potential to generate destructive waves within 1,000 kilometers (600 miles) of the epicenter. It advised authorities to take immediate action to evacuate coastal areas.
The tremor was centered 185 kilometers (115 miles) southeast of Padang in Sumatra, the island ravaged by the 2004 tsunami disaster that killed an estimated 230,000 people in a dozen nations, the U.S. Geological Survey said. It had a depth of just 10 kilometers (six miles) and triggered at least one strong aftershock, measuring magnitude 6.8.
Thousands of frightened people piled in trucks or sought shelter on higher ground.
Prayers up for the people in the area.
That is a total of 4 major (7. plus) earthquakes today.
Not counting the 5 and 6. aftershocks.
I’d be puking due to nerves at this point.
Those poor people.
The Northride quake occurred January 17, 1994. Sixty people lost their lives in the Northridge quake.

1971 San Fernando Quake
Oh, I got the names confused. It was the San Fernando quake in 1971...by 1994, I was in CO and missed that one. But, in 1992, there was a good one out in the desert, where I lived at the time. That one, I think, was in Desert Hot Springs area.
Second Earthquake Hits Indonesia []
9/13/2007 12:46:02 AM For the second straight day, a powerful earthquake rocked western Indonesia on Thursday, collapsing buildings and triggering tsunami alerts throughout the region.
The Pacific Tsunami Warning Center in Hawaii warned that Thursday’s new 7.8-magnitude quake had the potential to generate destructive waves within 600 miles of the epicenter. It advised authorities to take immediate action to evacuate coastal areas in the entire Indian Ocean area, including Indonesia, India, Sri Lanka, Thailand and the Maldives
The tremor was centered 115 miles southeast of Padang in Sumatra, the island ravaged by the 2004 tsunami disaster that killed an estimated 230,000 people in a dozen nations. The quake had a depth of just six miles and triggered at least one strong aftershock that measured magnitude 6.8.
A total of 141,000 people in the Sumatran towns of Curup and Sungaipenuh were exposed to Thursday’s quake, and the city of Padang was hit by a 3-meter tsunami.
That same area was rocked by another massive quake hours earlier that registered 8.4 in magnitude. At least 10 people have died in the quakes and dozens more have been injured., and nations as far away as Africa put coastal areas on alert.

People I know who lived here during the 1971 quake said that the 71 quake was far worse than the 1994 Northridge quake. The Northridge quake was bad enough.
All I remember about the 71 quake was thinking “it was never going to stop.” It seemed to go on “forever.”
I’m glad we weren’t right near it...at the time, I lived about 30 miles or so due east of LA.
Calling it a night here, bd.
Stay safe.
Another big quake Ping!
Thanks Nicmarlo, you too. Sleep well. :)
I am confused - how many actual quakes in the area today? Is a tsunami forecast?
Thanks for posting the story, nicmarlo.
Prayers for the people in this earthquake zone.
My earliest memory was the Tehachapi earthquake. I was three years old.
Prayers indeed. Thanks Cindy.
Thank-you so very much for the ping! :)

The Kern County quake was very big.
Historic Earthquakes
Kern County, California
1952 07 21 11:52:14 UTC
Magnitude 7.3
Fatalities: 12
This earthquake was the largest in the conterminous United States since the San Francisco shock of 1906. It claimed 12 lives and caused property damage estimated at $60 million.
...Property damage was heavy in Tehachapi, where both brick and adobe buildings were hit hard, and 9 people were killed. Three people were killed in other towns.
Although damage was severe, the total extent of damage to property did not exceed that in Long Beach in 1933. Only a few wood-frame structures were damaged seriously in this earthquake, compared to the 1933 shock in which many such structures were thrown off foundations.
