muikabochi 208 Posted January 9, 2007 Share Posted January 9, 2007 Just had a fairly strong earthquake here. Quite strong. Shindo 3 or maybe 4 perhaps. Same places as Chuetsu jishin. Scary. I really hate them. Link to post Share on other sites
mina2 6 Posted January 9, 2007 Share Posted January 9, 2007 Felt that fairly strong here. I bet that brought back a lot of terrible memories for a lot of people in that area very quickly. Link to post Share on other sites
SirJibAlot 0 Posted January 9, 2007 Share Posted January 9, 2007 Yes you did, info is below. If you drop the coordinates into google earth, you can see the exact location of the epicenter. -SJA == PRELIMINARY EARTHQUAKE REPORT == Region: NEAR WEST COAST OF HONSHU, JAPAN Geographic coordinates: 37.219N, 138.858E Magnitude: 4.9 Mb Depth: 12 km Universal Time (UTC): 8 Jan 2007 09:59:35 Time near the Epicenter: 8 Jan 2007 18:59:35 Local time in your area: 8 Jan 2007 18:59:35 Location with respect to nearby cities: 79 km (49 miles) SSW (192 degrees) of Niigata, Honshu, Japan 88 km (55 miles) NE (44 degrees) of Nagano, Honshu, Japan 93 km (58 miles) N (349 degrees) of Maebashi, Honshu, Japan 190 km (118 miles) NNW (335 degrees) of TOKYO, Japan Link to post Share on other sites
Kumapix 0 Posted January 9, 2007 Share Posted January 9, 2007 yeah, I felt that in Itoigawa Link to post Share on other sites
muikabochi 208 Posted January 9, 2007 Author Share Posted January 9, 2007 No more since that one, thankfully. An unkind reminder though. Link to post Share on other sites
SnowJapan Admin SnowJapan#Andrew 6 Posted January 9, 2007 SnowJapan Admin Share Posted January 9, 2007 Yes that was not nice. I could hear it a few seconds before the house moved. That nasty rumbling noise. It brought back a lot of memories in an instant. Link to post Share on other sites
Yuki's Passion 1 Posted January 9, 2007 Share Posted January 9, 2007 It couldnt have been that strong if the cows are still standing Link to post Share on other sites
SirJibAlot 0 Posted January 10, 2007 Share Posted January 10, 2007 4.9 close by is a pretty good jolt. Not to go too far off topic....Is there any precedent of earthquakes setting off Avalanches in Japan? -SJA Link to post Share on other sites
muikabochi 208 Posted January 10, 2007 Author Share Posted January 10, 2007 ...especially when you have had pretty terrible experiences in recent years and are rather sensitive about these things... It was quite powerful. I haven't felt one that strong for probably getting on for 2 years. Some memories: http://www.snowjapanforums.com/cgi-bin/ultimatebb.cgi/topic/8/3608.html?

gamera 0 Posted January 10, 2007 Share Posted January 10, 2007 At the Chuetsu jishin roughly 2 years ago, I felt it kinda strong shakings even here in Hakuba but this time I didn't. Hope people there are not scared now. Link to post Share on other sites
taguchi 0 Posted January 10, 2007 Share Posted January 10, 2007 I saw on news they called it yoshin 余震 from 2 years ago quake and maybe more in years to come. It is one unfortunate thing about Japan I think! Link to post Share on other sites
joshnii 2 Posted January 10, 2007 Share Posted January 10, 2007 Wasn't really strong here but I hear it was a shindo 4 where you are muika. Much have been an unwelcome surprise. Link to post Share on other sites
SerreChe 2 Posted January 11, 2007 Share Posted January 11, 2007 felt that as well but thought it was pretty short. May have missed part of it. Link to post Share on other sites
muikabochi 208 Posted January 11, 2007 Author Share Posted January 11, 2007 If you were in Yuzawa you wouldn't have felt it as much. It was a 2 there. Interestingly there's a fair bit of difference between Muikamachi and Yuzawa, just 20 minutes away. When Muikamachi gets a 4, Yuzawa gets a 2. (Well in the Chuetsu jishin cases anyway). Apart from the fact that it is further away of course, it seems that Yuzawa is built on more sturdy foundations than us in the valley to the north. Link to post Share on other sites
Yuki's Passion 1 Posted January 11, 2007 Share Posted January 11, 2007 Wonder if that region is going to collapse into the sea... Link to post Share on other sites
muikabochi 208 Posted January 12, 2007 Author Share Posted January 12, 2007 Nah, we are surely 'calming down' now (he says hopefully). It's someone elses turn next. Link to post Share on other sites

gamera 0 Posted January 14, 2007 Share Posted January 14, 2007 Yep, cal. I was just going up stairs, so I didn't notice the shaking but noticed the noise. Link to post Share on other sites
charlotte 0 Posted January 16, 2007 Share Posted January 16, 2007 I didn't notice that, though I am in Nagano here. Are there often ones in Hakuba? Link to post Share on other sites
muikabochi 208 Posted January 16, 2007 Author Share Posted January 16, 2007 Interesting how the tremors get spread. This one from this morning particularly interesting... goes way up north. Link to post Share on other sites
tsondaboy 0 Posted January 17, 2007 Share Posted January 17, 2007 Not that strange though if you consider the fact that the hypocenter was at 170 km, which would place it on top of the subducting Pacific plate. The plate is in contact only with the North-eastern part of the Japanese arc, so thats why you get that strange looking northwards spread on the intensity map. Link to post Share on other sites
muikabochi 208 Posted January 17, 2007 Author Share Posted January 17, 2007 Interesting tsondaboy, thanks. Link to post Share on other sites
SirJibAlot 0 Posted January 18, 2007 Share Posted January 18, 2007 I was surpried that I didn't feel it while in Niigata that eve, but when I saw the depth - I figured it was on the Pacific plate - however it's location seems to put it on the transform fault where the Euro, Philippine, and Pacific plates merge. I would have thought more shaking to the south, but perhaps you are right - it was the pacific plate at such a depth. Full report below... == PRELIMINARY EARTHQUAKE REPORT == Region: NEAR S. COAST OF HONSHU, JAPAN Geographic coordinates: 34.877N, 138.667E Magnitude: 5.9 Mw Depth: 168 km Universal Time (UTC): 15 Jan 2007 18:17:59 Time near the Epicenter: 16 Jan 2007 03:17:59 Local time in your area: 16 Jan 2007 03:17:59 Location with respect to nearby cities: 27 km (17 miles) ESE (116 degrees) of Shizuoka, Honshu, Japan 90 km (56 miles) ENE (77 degrees) of Hamamatsu, Honshu, Japan 92 km (57 miles) S (174 degrees) of Kofu, Honshu, Japan 132 km (82 miles) SW (229 degrees) of TOKYO, Japan Link to post Share on other sites
tsondaboy 0 Posted January 18, 2007 Share Posted January 18, 2007 The subducting Philipine plate base in that area is at about 70 km depth. Also the Pacific plate is not in contact either with the Philipine or the Eurasian plate, but is subducting inside the upper mantle at about 150 km depth. So basically it could have happened only on the Pacific plate at that depth. Link to post Share on other sites
SirJibAlot 0 Posted January 19, 2007 Share Posted January 19, 2007 Damn, I thought I knew a lot about earthquakes (being from California), but you are on it! I need to study the plate techtonics of Japan a little more closely - we should go boarding sometime.... Link to post Share on other sites
