You guys are derailing from the OP, this is about the new EQ around Indonesia not about Japan.

On another note:
All Tsunami warnings have been cancelled but local authorities are keeping their internal warnings in place for the time being! (-- that's what my local news is reporting --)

Can anyone confirm this further?

2007 had a total of 4 Earthquakes ranging above 8.0


Maybe above 8.0 is an average...some years you have none...and some years you have 4!

Anyway...that horse has been beaten enough!

Let's get back to the quake at hand!


I prefer to finish this debate first as i am sick of being told that i am lazy and wrong on certain things when i am capable enough to research. Glontra said that only one 8.0 happnes annually. 2007 had 4.

But yes, we should move on from that discussion.

5:21pm who's time..
my, hope everyone has time to get out of the way of this...


Obviously moving this slowly (about 35mi or 50km/hour) they have plenty of time to evacuate, no need to push & shove. Strange, I always thought they moved faster.

Your reckoning is incorrect... you are using just the amount of weeks so far this year... the average is A YEAR or 52 weeks. You could have just 1 in the first fifteen weeks of a year and ALL the rest to make up the average for the year in the last 37 weeks or the complete opposite. That is why it is called and average.

As of this very moment...HLN is still reporting a tsunami alert...but I think someone said that that alert was canceled few posts back in the thread!

HLN is a bit slow reporting too...so I don't know!

You say you are capable..so do it and prove everyone wrong but you and you'll sleep soundly and be the winner...

So has the Earth's axis shift from this one shortening the day yet again like Japan and Chile's
earthquakes did ?
Or was this 'quake not strong enough to cause a shift ?

I provided a link on the previous page. It is about the current state of earthquakes with 7.0 being the avg, with 8.0 being frequent.

I'm not sure if a horizontal slip is capable of that, my guess would be that it did nothing to the earth's axis.

Ok Kennvideo, here goes!

This is the type of post that I find irritating. Had this person read the ENTIRE thread they too would know that 20-30cms of water is enough to lift and move a car.

80cm and "is not so bad. Move along"

It may only be 80cm as it approaches shore but the height is not neccessarily the devastating factor, the weight of water behind the wave is, according to me, what matters and then it's not only the water as it pushes forward but the suction effect as it moves back into the ocean that has an even worse effect on an area which is probably already rubble filled!

This is not just a small wave that will break and recede, the build up of water behind the "head" of the wave could push this kilometres inland!

still alot better then the welcome he gets when he is at home. my thoughts go out to those in india. SKy news just reeported the tsunami warning has been lifted too. thankfully.

The frequency of earthquakes near the Pacific ring of fire has been a bit odd over the past 50 Years...

Bingo!!! It's the motion of the ocean inland..

Thanks for the guess

I've got no idea if both can cause a shift but your thought makes sense.
Direction should make the difference.

Of course this is on the Ring of Fire and subject to volcano's, active and dormant. There is also the tectonic plate structure there in the region. Notice that the plate is relatively small and circular in this region and it appears that the plate coming from India's area is exerting a easterly push.

I would not be surprised if this complete area is at some point in the future submerged by tectonic activity. It's logical that the region would have severe quakes, and that an 8.0 might be equivalent to a 4.0 on the United States western boundaries, rather it might be considered the expected average size. Hopefully evacuations will be successful in the event that there is a tsunami, Lord knows they have had more than their share of disaster there. I guess the civilized world only began really taking not since Krakatoa blew in the recent past. I would expect that more and larger earthquakes are in store for the region, after all it's in probably in the worst of all plate and volcano areas. Look at Japan..... and off the coast, complete areas submerged, the discoveries of ancient foundations, walls and the apparent city.

We'll be praying their spared any more calamity.

Actually I can see the entire plate subducting as its rolled around by the much much larger plates

Looking at the mechanics of the two different types of faults in the Japan/Chile vs. the one today in Indonesia, it is easy to see why the thrust fault would generate a larger, more devastating tsunami:



Source .pdf

The strike slip (or transform) fault is a horizontal movement wherein most of the motion leaves the two side of the fault at the same relative height to one another they were at prior to the movement.

The thrust fault generates a significant difference in vertical change, thus allowing for a greater volume of water to be moved.

That being the case, I could also see how a megathrust quake could have a larger impact on the rotational motion of the earth whereas even a large strike slip quake would not have as much of a vertical component.

how many weeks am i supposed to use???

if U want an AVERAGE, up to now,
how else can U do it???



PS here is the official tsunami report, of levels etc for THIS event...

see: ptwc.weather.gov...

i personally dont think so...

18 x mag 6+ is actually low... on average...


there are about 5 x MAG 5s E/Qs per day,
2 x mag 6 per week,
and one 7 per month,
and 1 x mag 8 per year...on average...

so we are in the 15th week of the year,
there should have been 30 mag 6s ( by my reckoning)
not 18.././

check out last year, ( which was bigger than average)
and the year before...

same place U got your figures from...
i think U will find there were more then, than this year...

I don't think your trying to be rude, but like I said, I was just expressing my opinion/observation. I'm not an expert and I'm not going to look up past years just to crunch numbers so I can prove someone wrong. Thank you for the extra info.

Why is it, that people on ATS always have to one up or prove everyone wrong? You can never just share or discuss anything on this board without being corrected. Explains why I usually only read and never post. I think I'll be going back to that.

Found this that explains a bit about our "guesses":


Q
The shift in the planet's axis and rotational speed that you've calculated for the Japan earthquake is different than for other huge quakes, like last year's in Chile and the 2004 Sumatran quake that spawned the enormous tsunami in South Asia. Why is that?

A
There are three factors that are important in this. One, of course is the size. If everything else is the same, then the larger the earthquake, the larger its impact on the Earth's rotation. Location is also important. If the earthquake occurs on the equator, then it's going to have a bigger effect than if it occurs at the north or south poles. If you move mass up or down at the north or south pole, it has no effect on the spin of the Earth at all. And then, the details of how the fault slipped during the earthquake—the dip angle of the fault and in what direction the slip occurred—is also important. Vertical motion is much more effective in changing the length of the day than horizontal motion that you get in a strike-slip fault. A thrust fault like [what caused] the Japanese earthquake has vertical motion; it is more effective in changing the length of the day than, say, an earthquake we'd get on the San Andreas here in California.


Source - Earth Axis Rotational Speed

Another source:

Only thrust earthquakes, with their inward motion, can shorten Earth days. Other types of earthquakes, such as horizontal strike-slip quakes, in which two plates slide horizontally past one another, don't affect Earth's rotation.
