Earthworms?[edit]

Someone added a bunch of uncited nonsense about earthworms fleeing their burrows. I am going to revert it unless someone can cite this. MikeJPalmer (talk) 09:27, 18 February 2009 (UTC)[reply]

A lengthy report on the Haicheng earthquake is available in Bulletin of the Seismological Society of America, v 96, pp 757-795. The authors- all Chinese- reviewed the recently declassified data surrounding this important earthquake and earthquake prediction, and put it in the context of modern Chinese history. They examined reports on peculiar animal behavior, among many other precursory phenomena. One minor example: some people reported that mice were unafraid of people in a period between foreshocks and mainshock. 136.177.30.205 (talk) 20:38, 28 January 2010 (UTC)StephenCHarmsen[reply]

Yes, StephenCHarmsen, the article you mention is the authoritative source. I inserted a ref to it, and modified the text to reflect what is in that article.MaxWyss (talk) 07:31, 15 April 2011 (UTC)MaxWyss[reply]

11-23 Revisions[edit]

Hello! As part of my Wikipedia Student Editing Project, I have made the following contributions to this article: 1. I rewrote the first paragraph, as the information was found to be plagiarized from another site. 2. I added a bit of description for this earthquake's classification, 7.3, on the Richter Scale to give average readers a more wordly understanding of the practical meaning of this scientific term. 3. I added hyperlinks to the following Wikipedia articles for further reading: earthquake, 7.3 (richter classification), infrastructure, property, groundwater, and soil. 4. I added two pieces of additional content to this article, each with a scientific reference (currently sources 6 and 7 in the article's bibliography). The first contribution can be found in the second paragraph, "A low-level alert was triggered by regional increases in seismicity (later recognized as foreshocks). Both authorities and citizens were finally placed on high alert and an evacuation order was issued due to an increase in foreshocks." This information elaborates on the warning signs scientists used to predict this earthquake before it occurred. The second contribution can be found in the final paragraph, and it explains the usefulness of this one earthquake's successful prediction to the scientific community and what it could mean for the future of earthquake predictions. --Daniel Ducote (talk) 07:47, 23 November 2015 (UTC)[reply]

Needs rewriting, based on a review of the literature[edit]

While this earthquake is considered very notable, and warrants a suitable article, I find this article to be quite deficient. At present it presents a very shallow, uncritical bare-bones account, based on a handful of websites (some now "404") that only echo the authoritative sources. (The one significant source, Wang et al. 2006, is also inadequately cited.) I am going to add some tags, but this article really needs to be rewritten, based on a review of the literature. For anyone that is interested (and has the time, which I don't) I can recommend some sources. I suggest starting with the pertinent sources at Earthquake prediction. ♦ J.

Earthquake prediction scrutiny: Last paragraph[edit]

The last paragraph in Natural occurrences and earthquake prediction (§Earthquake prediction scrutiny) refers to the 1976 Tangshan Earthquake in a somewhat convoluted manner. Munchyhunch (talk) 00:01, 12 February 2023 (UTC)[reply]
