thread_title:  Volunteer Day by Cabinet order? 

message: Do any of you know a good source in English which includes a plain explanation of "how an active fault inside a land plate causes an earthquake"? Kobe earthquake was of this type, so it made a term "活断層" (katsu-dansō; active fault) more famous in Japan, or  infamous, I should say. --Dumpty-Humpty (talk) 17:07, 3 May 2008 (UTC)
thread_title: Sources for "Plate tectonics"

message: When a cause of earthquakes is explained in English, the most popular one I guess is energy release around a plate boundary. Probably that's why no editor pointed out it's not the case with Kobe earthquake for this article for 2 years. --Dumpty-Humpty (talk) 17:07, 3 May 2008 (UTC)

message: ===Plural magnitude scales===
In news reports, a magnitude estimated by Japan Meteorological Agency is often described for accommodation as that on the Richter scale. However, JMA uses another scale than the Richter magnitude scale, which was the first-introduced magnitude scale in the world. --Dumpty-Humpty (talk) 02:46, 1 May 2008 (UTC)
replies: text: I read again the winding news release from JMA to know that the JMA magnitude of this earthquake was adjusted to 7.3 and it stays as the same after this revision. So I modified the expressions in the article as so.--Dumpty-Humpty (talk) 05:37, 17 January 2010 (UTC)

thread_title: Two JMA magnitudes

message: I found this article's section "Seismic Intensity" was showing confusion between magnitude and seismic intensity, so I cleared it up. Magnitude shows a size of an earthquake itself, so it does not differ by observation points. Seismic intensity is a size of tremors observed at a particular place.--Dumpty-Humpty (talk) 05:37, 17 January 2010 (UTC)
thread_title: Misunderstanding about seismic intensity

message: I've found that the largest foreshock of the four was observed at 18:28 the previous day and it measured 3.7 on the revised JMA magnitude scale by searching JMA database of felt earthquakes. As to the magnitudes of the 4 foreshocks, this paper (in Japanese) supports the expression "between 1.5 and 3.6" which I modified. However, that may be a recalculation of the data from a research center of a Kyoto University's institute, which observed the foreshocks and says the largest one was estimated at M3.3 (in Japanese). --Dumpty-Humpty (talk) 03:36, 1 May 2008 (UTC)
thread_title: Foreshocks

message: - I aggree that at this point, this article is a 'B.' there is a lot of literature on the earthquake, mostly in jp, to be fair, but surely there must be better sources in English. 
- provate efforts section: this section focusses on corporate efforts, but does not mention the contributions of ordinary citizens, which was by some acounts the most effective and numerous. Curiously enough, i gather organized crime also engaged in relief efforts, though don't have research on hand.  
- 'other effects' section:  the word 'volunteer' entered the japanese vocab at that time and the japanese NPO law was created partly in response to the growth of citizens organizations established to provide relief. remember that japan does not have a charity culture like, say the UK and historic non-profit sector like, eg.  Germany.
an imporant local institution established at the time is fm waiwai, a multi-lingual broadcaster set up to emergency information to foreign residents (esp. Vietnamese and Korean).

message: Hi! I experienced the Great Hanshin Earthquake when I was 1 year old. I almost died.
Woah. Where were you? What happened, and do you remember what it looked like?
Do you think you could tell me what happened? because it would be a great help for my geography project.
I just saw a documentary about the Kobe earthquake on Discovery. They showed pictures of the faultline visible to the naked eye. One plate higher than the other, as Kobe lies in a subduction zone. Could someone upload a photo of that? Jordskjelv 13:40, 18 February 2006 (UTC)
thread_title: Personal experience

message: "  It was the worst earthquake in Japan since the Great Kanto earthquake in 1923, which claimed 140,000 lives, and it is listed in the Guinness Book of Records as the "costliest natural disaster to befall any one country," but it is expected that this earthquake will cede that title to Hurricane Katrina for the 2007 Guinness Book of Records.  "
The Great Kanto earthquake article states that that quake did over $1 billion damage in contemporary dollars, which would probably put it over the estimated $75 billion of Katrina when adjusted for inflation.  Additionally, this article states that the Great Hanshin quake did $100 billion dollars in damage, which is far larger than Katrina's damage.  Accordingly, I am editing the article.  --172.164.108.116 02:54, 18 March 2006 (UTC)

thread_title: A very good source on the quake

message: Sorry, but that paragraph has got to go. Someone with some expertise, please help here. Weren't they about the same size? And wasn't the epicenter of the Northridge Quake directly under the city? Wasn't the epicenter of the Hanshin Quake in the bay somewhere? InFairness 22:56, 4 April 2007 (UTC)
replies: text: Northridge was a magnitude 6.7, and Kobe was 7.3. The paragraph states that they were "similar" strength earthquakes and questions why there was more damage in Kobe. This makes no sense because the two earthquakes were not similar strength at all, because the Richter scale is logarithmic. The energy released by the Kobe earthquake was 8 times greater than the Northridge earthquake. (Difference in magnitude is 0.6, so factor of extra energy released = (10^0.6)^1.5   See: http://en.wikipedia.org/wiki/Richter_magnitude_scale For this reason, I have decided to remove the paragraph comparing to the Northridge earthquake, because the two earthquakes were not similar at all. 31.208.65.156 (talk) 00:12, 15 August 2014 (UTC)

thread_title:  Bad source 

message: I remember that following this earthquake there occurred a worldwide shortage of computer chips.   This was apparently because the factory making most of the world's production was located in Kobe, and had been put out of action for a very long period.   A black market in computer chips developed, and burglars began stealing chips to order.  I remember coming into the office (in London UK) once day, to see all the PCs lying on the floor, with CPU boxes opened and microchips stolen - everything else including hard disk memory was intact, as the thieves had a sense of decorum. The bosses were then forced to buy back chips on the black market in order to get the office back into operation again.   16 July 2007
[Nov 2009] I remember this too ... as I recall, the factory in question was making not chips, but rather most of the world's supply the black plastic outer material used for packaging and "bond out" in the business. I was living in the UK myself at the time, and retail prices of (legitimately sourced!) DRAM chips rose sharply and stayed at around GBP 30 per MByte for at least 18 months afterwards, rather than following the typical Moore's Law curve.  —Preceding unsigned comment added by 208.123.82.30 (talk) 23:28, 6 November 2009 (UTC)

thread_title: Kobe earthquake and Sunflower in Japan

message: Under this section, there is an explanation of how the Richter Scale works, etc.  It is not really relevant to have it in the article ABOUT the Hanshin Earthquake.  It's not really information specific to it; the article should just provide a link to the article Richter Magnitude Scale.Yumehoshijima (talk) 01:44, 10 November 2008 (UTC)
replies: text: Not only is it not relivant since the measurement given is on the Japanese scale, the explination is incorrect. An increase of 1 isn't a factor 10, its aprox 31ish, and an increase of 2 is 1000.

thread_title:  Deaths in Kobe > Total Deaths ??? 

message: Also in Japanese this earthquake and the disaster are sometimes crowned with "Kobe," the name of the megacity which underwent huge damages.  is a name for the disaster, not for this earthquake, so I separated this name from "Great Hanshin Earthquake" in the article. Daishinsai means large (dai) disaster by earthquake (shinsai), i.e. earthquake calamity. NHK uses this official name approved by the then Cabinet. The placename Awaji is often omitted by other news media. --Dumpty-Humpty (talk) 05:03, 17 January 2010 (UTC)

message: I placed two tags,  and , at the top of this subsection, whose content ([ as of 2010-01-18 21:28 UTC]) is thoroughly sourceless and even does remind me of a Japanese phrase meaning 'a lie told as if one had observed the scene.' Every survivor who was actually at the scene must have been scarcely enough to help himself/herself (and his/her relatives or friends) for the first few days. It's very regrettable if the content stayed almost the same without any reliable source at least for about 18 months, as is suggested by an inter-revision difference. Here I list some points. --Dumpty-Humpty (talk) 23:40, 21 January 2010 (UTC)
replies: text: Gus lines: I removed the sentence beginning with "Ruptured gas lines ignited," which is dubious. (Does anyone know a good source in English?) Osaka Gas says in this page that the company shut off gas supply for many customers so as to prevent secondary disaster. By the time of this quake, microcomputer-controlled gas meters (designed to suspend gas supply when large tremors are detected) had prevailed to a certain extent, about 75 % according to a chart in Chapter 5 of this databook (Osaka Gas, 2009). This chart also says that quake-resistant gas pipes covered 68 % of the gas-pipe network. --Dumpty-Humpty (talk) 23:40, 21 January 2010 (UTC)

text: Wooden houses: Unreinforced structure is probably one of major causes, but does not completely explain the huge damage. I've heard that one reason why many flat houses collapsed was that the seismic wave included strong short-cycle tremors causing sympathetic vibration of low buildings: if this quake had caused powerful longer-cycle tremors around the noon, it must have led to greater causalities in taller constructions. (Actually, the two Niigata large quakes in 2004 and 2007 made high buildings sway in Tokyo, far from the hypocenters, which fortunately killed no one.) --Dumpty-Humpty (talk) 23:40, 21 January 2010 (UTC)
