8.9 (updated 8.7) QUAKE off the coast of Sumatra! Oh my......

reply to post by detachedindividual

This event is still unfolding, lets just hope the worst is already behind us...

Kinda! its hearsay at the moment as the scientists are working overtime to figure it all out,

Its does happen but rarely,.

Well, earthquakes above 8.0 usually only happen once per year.

I think now we're safe for the rest of the year of 2012.

If another quake above 8.0 happens in the next months, that will be definetely NOT normal.

I agree Asala, so many people here with such a vast array of knowledge, apparently, but so few of them are prepared to put their money where their mouths are!

Basically if you have nothing to add to the thread why even bother reading it?

Give people like Puterman and Asala the respect that is their due!

I read the threads but seldom say anything because I know that there are much wiser people than myself whose opinion I appreciate!

Thanks to all out there who have added anything, no matter how small, of value to this thread!

You sell yourself short..you must have an opinion and if stated, you may make the so called 'experts' here scratch their head and go jeez, this person has got a valid point... IMHO

AFP: At least three tsunamis of up to 80 centimetres (31 inches) have hit Indonesia's coast after the Sumatra earthquake. "Our tide gauges and buoys recorded small tsunamis," said Kristiawan of Indonesia's Meteorology and Geophysics Agency.He said the highest was in Meulaboh in western Aceh, "measuring 80 centimetres", and other smaller ones were recorded in nearby coastal regions.

Let's hope that this doesn't get any worse for these people!

Looks like many of them have seen the waves from the first quake come in and are heading back to lower ground. There is still a risk from the second quake - let's hope there are no more aftershocks that produce more.

Japan had the 9.2 Earthquake last year, followed by numerous 8+ "Aftershocks."

Aftershocks

Bull#, they were more earthquakes.

Anyway, the point is, there was the 9.2 in Japan followed by numerous 8.0s last year.

Global CMT has the big shock at just 8.0. So the aftershock was probably in the 7.6 range.

PS.PSI (one of the few stations we have access to in Sumatra) went out after the large aftershock. So we are blind at Toba now...

Another station is still working on the south side of Sumatra. That 8.0 clipped PS.PSI completely. I pulled the helicorder data. They need a more robust station there, capable of actually HANDLING the massive quakes they get....not to mention if Toba should decide to act up...

Thank you! I think! Hehe!

I find earthquakes and volcanoes fascinating, have done since I was a child and saw the movie "Krakatoa, East of Java", but when I was at school we did no studies in either of those directions.

It is only since I discovered the amazing world of ATS that I have rekindled my desire to really learn more about both subjects and as such I am a child at a kindergarten going on 54!

ps. Just to add that I am at work and ATS is at this stage my only link to what is happening out there, so thank you all! And especially to Westcoast who authored this thread!

If anyone interested, here is a live stream from NDTV India. (commercials and all)

www.ndtv.com

Also I found a twitter account that seems to be pretty good. twitter.com/mpoppel

I'm thankful there is no wide spread destruction. From watching the live stream it seems the tsunami fear is coming from the amount of aftershocks breaking something loose on the sea floor.

OiO

Just read..... Ache wave was downgraded to 80cm.... how ever anyone could mistake a .8 metre wave for a 5 metre one is beyond my understanding. Nevertheless it will most likely still cause severe damage to the area.

Looks like things are scaling back.

India has ended its Tsunami alert. USGS is downgrading its area of Tsunami risk to affect a smaller region.

It's great that nothing major has actually happened, but it does make me wonder how long it'll be before people refuse to heed warnings.
It's Human nature to become bored with those crying wolf, and the vast majority of those killed in Japan last year knew what happened in 2004.

I guess it's Human nature to take risks or believe that you are somehow immortal, or more in-tune with the planet than others. I think we just underestimate nature far too much.

Thankfully this earthquake was caused by a horizontal slip, which means it won't displace much water.

The problem is if the earthquake was caused by a vertical slip. Those are the ones that displace huge amounts of water like what happened in 2004.

My thoughts are with everyone in that area. Let's hope no one was harmed, but a quake this big in these regions is almost certain to have taken lives...

Can you show me a SINGLE aftershock of the Japan quake that had a magnitude above 8.0

I'm challenging you.

I bet you won't find any...

Thank you for confirming what I said.

Right at the side of "Great 8 and higher " I'm seeing the number 1 (one).

Just like I said...

Japan experienced over 1000 aftershocks since the earthquake, with about 60 registering over magnitude 6.0 Mw and at least three over 7.0 Mw. A magnitude 7.7 Mw and a 7.9 Mw quake occurred on 11 March and the third one struck offshore on 7 April with a disputed magnitude. Its epicenter was underwater, 66 km (41 mi) off the coast of Sendai. The Japan Meteorological Agency assigned a magnitude of 7.4 MJMA, while the U.S. Geological Survey lowered it to 7.1 Mw. At least four people were killed, and electricity was cut off across much of northern Japan including the loss of external power to Higashidori Nuclear Power Plant and Rokkasho Reprocessing Plant. Four days later on 11 April, another strong magnitude 6.6 Mw aftershock struck Fukushima, causing additional damage and killing a total of three people.
As of 16 Mar 2012 aftershocks continued, totaling 1887 events over magnitude 4.0; a regularly updated map showing all shocks of magnitude 4.5 and above near or off the east coast of Honshu in the last seven days showed over 20 events

I have had a look, but as of yet can't find a source (Only looking in wikipedia so far, not reliable). However, I remember hearing at the time on the news that they were all 8+, then downgraded.

I feel very sorry for these poor people.

All of you living in an earthquake zone I know its easy to put it aside just as those of us livining around hurricane zones, but when you read of something like this happening, doesn't it just creep into the back of your mind. I hope evrybody is prepared for what may happen.

Since the main quake off Japan's northeastern coast, hundreds of magnitude 5 aftershocks and dozens of magnitude 6 aftershocks have struck the island of Honshu, Japan's largest and home to 100 million people. The largest aftershock was a magnitude 7.9 that struck less than an hour after the main shock.
