Was in Japan a couple of weeks ago and went to go hop in a lift and got that feeling that you get when you have been on a boat for ages and then hop in the shower and everything feels a bit wonky.
Was concerned for my saftey in the lift and everyone just piled in so figured it is just a part of life? Zen you must be used to it......

Pretty scary stuff, especially seeing how close it was to the Sumatran coast. Hope it doesn't do too much damage to property or life :(

just got told it was a 'horizontal quake" so shouldnt be to bad (from an unreliable source).... certainly hope so.

8.58pm: Witness tells Reuters agency that sea water at Simeulue Island near epicentre of quake has been receding by about 10 metres.

9:16pm: Indonesia's geophysics agency now says there has been another aftershock off Aceh of 8.1 magnitude, with the potential of a tsunami to follow.

I don't really know what to say, hope everyone is ok. Keep an eye on each other, help out if you can and keep your bravado in check.

reecen, I avoid lifts if I can. The stairs are healthier anyway.

Spongy, we're still getting tremors regularly here. Might go a week without one, then might get 2 or 3 a day. Rare to go a week or more without a shake.

After seeing what the Tsunami did to my area, I'd be pretty edgy if I was in one of those land camps right now. Stay safe everyone.

Reports from various surf resorts and charter boats in Sumatra, expats etc (stuff you wont hear on news)

Both quakes were felt all through Mentawai's from maccas resort to surf camps in playgrounds area further north.

Padang where charter boats are based also felt quake and eveyone started heading to hills.

Telo's, nias felt the quake bigger causing panic but no real damage.

Up north in Simeulue and Aceh coast felt much bigger shake as much closer to centre, charter boats there headed for deep water and some areas of coast got a small surge of half a metre or less not sure if any damage to surf camps at Simeulue or banyak islands from actual quake, there is two in Simeulue another getting built there and one in banyaks.

Only fear is once the fault line gets active, normally get a few more hopefully just small ones or type that dont cause Tsunami.

How are some of those periods recorded at those stations.. 18 minutes!!

That shows how destructive these tsunamis are if they have a bit of height to them as I would guess you could expect the sea to seemingly keep pushing inland for at least 9 minutes (probably more - due to frictional effects of the land), before slowly receding again.

Luckily this was a horizontal slip and not vertical as it could of been a lot worse.

Here's something you might find interesting Craig.

Geological and historical records of tsunami in Australia

Extract.

The maximum run-up for a palaeotsunami is +100 m
above sea level (m asl) — possibly as much as +130 m
asl (event ID number 5 in Appendix A) which is
recorded at Steamers Beach, Jervis Bay, New South
Wales (see Fig. 3 for location). This event occurred at
circa 8700–9000 BP. It is not known what process
generated this tsunami, nor where it came from. A
tsunami that is reported to have occurred at circa
6500 BP may have inundated to a distance of 10 km
inland across the Shoalhaven delta area of New South
Wales. Again, no information is available about the
cause or origin location of this event.

With regards to tsunamis caused by submarine landslides, there is some evidence and/or anecdotal reports of tsunamis occurring along the central and southern NSW coasts in years gone by - the Bulli Slide (on the steep continental shelf) being a possible source.

How about Ice shelf collapses .
A long time ago atleast 10-15 years ago , myself and mate were surfing a well known Offshore reef ( it actually now has a wave cam pointed at it these days ) . Anyway it was reasonably solid ( 4-5ft ) it can hold maybe 6-8ft . And there is usually 25m difference on where it peaks form those sizes. The inside section of the Right can tricky when it gets bigger and both of us got caught out and were just getting close to clearing the shallow inside and resuming the shortish 50-100M paddle back to the Peak .
Regardless of how big it is , off the back of the outer point of the Reef , it drops into reasonably deep water .
Anyway we got caught out by what appearred to be a second set in close succession . BUT every wave just got bigger and bigger . After about 2-3 we were copping them on the head . The 5-6th ones were reforming on us , and at a guess it had got probably a foot or two bigger on each wave . My last opportunity to guage what i could see out the back was waves breaking way outside the usual takeoff ....
We had been washed ( after about 10-12 waves ) well inside and had given up , hoping to get washed around with the natural flow back out through the Left . Only it still didn't stop and by ( guess of 15-20 waves ) we had been washed back into the
( lagoon of sorts ) a distance of atleast 400-500M's . ( The left is probably 200-300M's from shore , the far right hand side of this offshore bombie could be close to 800M's from the internal bays shore line ) . We were both shaking our heads and then had to deal with a 10-15 min struggle with a seaward current that was now trying to drag us back out around the Left . We got to shore and just shrugged it off to a Freak set , and went for a feed ......

Two days later i'd red in the Paper of a Major Ice Shelf collapse off Antartica , and unconfirmed reports of " Harbour Troubles " in the states Far west ........ From memory it was a like a 1-2Km ??? ( or that could have been 10-20 ) wide iceberg that had been noted floating Nth after the fact . Might have to do a Newspaper search to confirm ?
This was also mid week , and probably no where else on that coast would've been surfable . So no other surfer that i spoke to ( not many , after the first few peoples reaction [ yeah sure !! ] ...... ) and so forth ..... anyone else remember anything weird around 2000 ???
( southern states only ) ....

Interesting story Southey, was there visible inundation of the shore and beach or was it just a big continuously growing set of waves?

Regarding the collapses of land forms, have you ever read the story about the Alaskan earthquake of 1964 with the collapsing of silt and land in Prince William Sound where the town of Valdez is situated along one of its fjords?

It's an amazing story and is summarised quickly here.. http://www.usc.edu/dept/tsunamis/alaska/1964/webpages/1964valdez.html

But basically the land fall caused a displacement of water in the protected fjord causing a tsunami which reached huge heights (67 meteres at the Valdez Inlet from one source) and rebounded back and wiped out the town.

There was a classic aerial photo taken after the event and you could see the pine forests on either side of the fjord were stripped 10's of metres up the mountainside.

@ craig .

The only shoreline that faced open ocean in those parts is close to being or is a Cliff . The lower areas are all behind the Fringing reef . Ontop of this , the area would regularly see 10-15 ft of storm swell . So while i didn't actually see any evidence of shoreline " run up " , it didn't mean that it didn't happen . Put it this way i didn't notice any signs of it , but back in those days apart from the G-land camp episode , it wasn't something as fresh in my foremind as say since the Indian Ocean tsunami , of which i experienced first hand in one of the worst hit spots in WA .
I can't be certain of the tide that day ( ice shelf collapse ) , and since we were surfing the right it must have been in the upper quarter of the tide . So although the " lagoon " as such was running /streaming back out to see , on a solid swell and outgoing tide this spot can at times feel like a "reef pass " with the amount of water returning through this deepwater path .

So i would also say , it was just like a long set of oversize " boatwakes " ( Not sure on period , the first few didn't seem further apart than the probable 15-16 sec. period swell of the day . Which is what i would presume to be the resultant of a displacement ( by Ice = a floating substance ) as opposed to a landslip like the Alaskan one which i have read an account of a while back , after it came up in discussion during the Japan Quake on WZ . So i reckon ice Tsunami would be different to EQ , or landslip or even the Krakatoa collapse . I'm sure there is heps of different wavelengths from differnet EQ subduction scenarios alone .

GW ' maybe someone to ask , especially with all his " displacement study of late "
( Kelly's probably still too busy watching / analysing the re-runs of the Bells Final ) !!! LOL .

Unfortunately like many other things " deep beneath " the human race is let to master/ know and fully understand/comprehend .

If you get time , reading up on Exmouth's history , including why the " natives " still see it as taboo/ no go zone could be interesting. Its not just because its a Cyclone magnet . Infact i reckon the Salt lakes in that area would have been helped along / replenished from time to time ....

By: "freeride76"

Maccas is set up even better now and places like pitstop hill are on high ground, but there is a fair few camps/resorts that are on Islands that have no real high ground or no strong high well designed buildings.

Has got to be a factor these days in choosing a surf camp/resort in offshore sumatra island chain?

Its also scary to think but scientist have predicted the next real big quake is predicted of Siberut in Mentawai's a Tsunumi would plow right through all the camps in playgrounds and Telescopes area, they say it could hit in next 30 seconds or 30 years, but is going to happen.

indo-dreaming commented Saturday, 14 Apr 2012 at 12:32pm

there is a fair few articles online about the prediction here is a surf related one

www.surfersvillage.com/surfing/44668/news.htm

here is a bit taken from article=

"We are wondering whether there could be another big earthquake down in the south end of the 2004 section, which could break sometime in the next few decades as well," Sieh said. The Mentawais fault line runs under the sea and any major quake is expected to rupture the ocean floor causing a tsunami.

In 2004 the quake spread a tsunami across the Indian Ocean to India and Africa. A tsunami generated from a Mentawais quake would send a wave southwest out into the empty Indian Ocean. But the wave would also hit Sumatra's densely populated coast between Padang and Bengkulu, although the Mentawais island chain would help dissipate the wave's energy before it hit shore.

I'm wondering if we're going to get another big one? We've had six 5+ magnitude tremors here (my area, northern Kanto) in the last 48 hrs. Had a good one last night, sitting in traffic at a standstill with the car rocking, thought it was windy, but it was a long slow shake lasting about 30 secs. Plus up until going to bed there were 3 or 4 little tremors.

Got shocked out of bed at 2.30 am a couple of weeks ago, that was a 7. We had a couple of weeks with barely a tremor and in the last couple of days it's seemed to have ramped up a bit.

Seems every other day the ring of fire is throwing one out there.
