SnowJapan Moderator SnowJapan.Com#4 5 Posted January 21, 2006 SnowJapan Moderator Share Posted January 21, 2006 Not sure ug - we were just wondering that too.... (It has been deleted now, but for those of you wondering what is happening, rahul posted exactly the same thing for the 4th time just a few moments ago) We've given rahul a cooling off period!

sunrise 0 Posted January 22, 2006 Share Posted January 22, 2006 I wouldn't call snow in Tokyo on the 20th a natural disaster. In fact it's been very beautiful, I had a nice time out with my camera. A few flights cancelled, trains delayed early on, nothing any different to a passing typhoon, plus some people hurting themselves cos they were walking around in the wrong shoes doesn't mount up to me as a natural disaster. I appreciate Rahul is working hard to improve his predictions, but his prediction indicated a snow disaster on the 20th. (Actually, it didn't start snowing until the 21st, in the very early morning.) SJ guys, I'm not sure if Rahul reads all the posts in this thread, so he may not have seen what you wrote. Anyway, my prediction is for a great weekend next weekend at the SJ party in Hakuba.

SnowJapan Moderator SnowJapan.Com#4 5 Posted January 22, 2006 SnowJapan Moderator Share Posted January 22, 2006 sunrise - the same post went up 4 times during the day, and as well as posting on here we did email him twice (without a response) --- there is not much more we can do if we want to avoid, er, flooding We're sure he'll be back fairly soon!

7-11 2 Posted January 22, 2006 Share Posted January 22, 2006 Yes I think we are far from having a "disaster". I made a small snowwoman today. She had - a carrot for a nose; - 2 manju for her eyes; - a bunch of Pockys for her admittedly strange nose; - 2 meron-pan for her chest She was very pretty. Link to post Share on other sites

Ocean11 0 Posted February 1, 2006 Share Posted February 1, 2006 Yep. A brief moment of acceleration in our kitchen. Bastards. Link to post Share on other sites
Mudguts 0 Posted February 2, 2006 Share Posted February 2, 2006 Woooow! That rocked In Tokyo! Who felt that one? Link to post Share on other sites
sunrise 0 Posted February 2, 2006 Share Posted February 2, 2006 A bit of a jolt, I wonder where it was centred. Link to post Share on other sites
Ocean11 0 Posted February 2, 2006 Share Posted February 2, 2006 Wonder no more This one was ours. I actually felt the direction of the shock wave move from west to east through my chair. Link to post Share on other sites
muikabochi 208 Posted February 2, 2006 Share Posted February 2, 2006 Felt that here even, just a bit. Happily, it didn't freak me out much at all. Thats a good sign. Link to post Share on other sites
HeatherLocklearRocks 1 Posted February 2, 2006 Share Posted February 2, 2006 That was a scary one, one of the strongest I've felt I think. No "aftershocks" it seems. How big do they need to be to have all those aftershocks? I remember the Niigata one seemed to on for months and month with literally hundreds.. Link to post Share on other sites
bushpig 0 Posted February 2, 2006 Share Posted February 2, 2006 I don't think it's a matter of how big, but rather whether the friction build up is all released by the first shock or not. If not, and if slippage is still happening then there will be aftershocks. Link to post Share on other sites
HeatherLocklearRocks 1 Posted February 2, 2006 Share Posted February 2, 2006 Yes I see that. Just interesting that something like yesterdays was just 1 on its own, then something admittedly considerably more powerful with hundreds of shocks going on for ages. Scary shit whatever.

tsondaboy 0 Posted February 2, 2006 Share Posted February 2, 2006 Basically you don’t get many aftershocks from this kind of events for 2 reasons. The event was pretty deep 110 km. At that depth the earth’s mantle behaves more in a plastic way rather than in a brittle sense. So basically only big movements are allowed and all the stress built up is released at once. The plastic behaviour of the mantle doesn’t permit smaller movements. Also even if there are a number of smaller aftershocks they are attenuated by the 100+ km of the earths mantle/crust lying above, so it is almost impossible to record them.

scouser 4 Posted February 3, 2006 Share Posted February 3, 2006 Felt that the other night too, I was on the 20th floor and we sure did move I can never get used to that. Link to post Share on other sites

SnowJapan Admin SnowJapan#Andrew 6 Posted February 3, 2006 SnowJapan Admin Share Posted February 3, 2006 Felt that here in Yuzawa even though it was nowhere near us (off the east coast of Ibaraki?) The room was swaying a bit and I thought to myself "was that an earthquake?", then didn't really think much more of it..... until this thread made an appearance at the top of the list and I check out the quake website and sure enough it was. Even though nothing was registered for Yuzawa. After the Chuetsu I think I have ultra- sensitive powers about these things, unfortunately Link to post Share on other sites
muikabochi 208 Posted February 3, 2006 Share Posted February 3, 2006 A big one does that to you it seems, I felt it too. Link to post Share on other sites

bushpig 0 Posted February 3, 2006 Share Posted February 3, 2006 my building here in Hiroshima was swaying for a while there, but that may have been more to do with the garlic pasta I had eaten earlier Link to post Share on other sites
sock_monkey 0 Posted February 3, 2006 Share Posted February 3, 2006 there were two earthquakes in the last couple of hours 4.8 off the coast of Sendai and a 5.8 off the coast of Chiba Link to post Share on other sites
soubriquet 0 Posted February 3, 2006 Share Posted February 3, 2006 While everyone's paying attention, I have a question for tsondaboy. These are two seismograms from different sites in Kobe, from the 1995 earthquake. The site for the left hand seismogram was on solid rock, and right hand seismogram from a site in a sedimentary basin. Clearly in a basin of saturated sediment, the intensity and duration of the event is much greater. I have seen this referred to as "amplification". Is this genuinely the case? The only mechanism I can see for "amplification" is if the P waves are reflecting back and forth off the margins of the basin, and you are getting constructive and destructive interference. Anyone?
