Category:Places affected by the 2010 Chile earthquake

Category:Places affected by the 2010 Chile earthquake was deleted at Wikipedia:Categories for discussion/Log/2010 March 1 - but I don't see how consensus was achieved, and no administrator's decision comment was added to quote some policy to override the discussion that occurred. 70.29.210.242 (talk) 03:45, 15 March 2010 (UTC)

• Agreed. It was an outrageous stitch-up by a dodgy cabal. Ongoing discussion here: Wikipedia:Deletion_review/Log/2010_March_15. Ericoides (talk) 14:53, 16 March 2010 (UTC)

The category was restored and the decision was overturned. The category now needs to be repopulated. 76.66.194.32 (talk) 05:05, 24 March 2010 (UTC)

I don't think it's appropriate to add articles to the category that do not even mention the earthquake on the article itself... which someone is now adding to articles that don't mention the earthquake at all... 76.66.192.73 (talk) 05:18, 27 March 2010 (UTC)

2009 pandemic flu in the quake zone

According to Xinhua [1], there's been Mexican Flu detected in the quake zone. 76.66.192.73 (talk) 05:48, 27 March 2010 (UTC)

Its only a single case, so it doesn't seem particularly relevant. -- Eraserhead1 <talk> 08:59, 27 March 2010 (UTC)

Juan Fernandez Islands tsunami height

Hi. The tsunami height of the Juan Fernandez Islands, particularly at Robinson Crusoe Island should be included inthe tsunami arrival table, but I don't have the exact time of arrival. Initial estimates were of a 40-metre tsunami, but later reports indicated 3 metres. The Times Online source appears to be adequate as an individual ref for this height but we need an arrival time. Thanks. ~AH1^(TCU) 17:15, 28 March 2010 (UTC)

The NGDC catalogue list of run-up heights gives 5.0 m for Robinson Crusoe Island but unfortunately does not include a travel time. Mikenorton (talk) 20:43, 28 March 2010 (UTC)

29 March quake

We have an article, 2010 Biobío earthquake, for a 6.7 quake in mid-March, but there was a 6.1 on 29th March in Biobio... [2]

2010 Chili Earthquake

I question the authenticity of the top picture associated with this article. There appears to be too much of the building that remains undamaged for the building to also have split apart and tilted so wildly. There is even unbroken glass which would seem impossible for that to be in a building that underwent such an upheaval. There is also a website on the wall in front of the building, which is either coincidence or proof of a fraudulent picture.

A quick check of google images turns up many pictures of the same building from different angles. It looks entirely genuine. Mikenorton (talk) 19:44, 12 April 2010 (UTC)

Length of day alteration

This NASA nonsense about the quake shortening the length of day needs to be addressed. If every "thrust" quake shortened the day by reducing the earth's moment of inertia, the earth would indeed speed up, and tend to become more oblate, i.e., fatter, not skinnier. These NASA scientists have the earth pulling itself together by its own bootstraps. We have 1) unverifiable speculation on the length of day; 2) verifiable but unverified (non-NASA) speculation on the raising of Isla Santa Maria by two meters; 3) actual GPS measurement of Concepcion having moved 3 meters to the west. Accordingly Concepcion's sidereal time was delayed 8 milliseconds, and it would take thousands of years for the city to catch up with its former time if its day were shortened according to NASA predictions.

Some things do affect the earth's rotation against the usual deceleration, like seasonal accumulation of snow in northern latitudes. Sea level drops a few mm--more in the north than in the south, and the polar (i.e., the lithospheric, not total) diameter shrinks a tiny bit, while the earth's center of gravity shifts northward. There is both an elastic and an inelastic response in the lithosphere. These things happen on a much larger scale as the earth goes in and out of ice ages, and post glacial rebound counteracts the effect of receding ice sheets late in the melting stage.

But all in all the earth tries to stay round, and is affected primarily by gravity and rotation. As the rotation decreases over the aeons it gets rounder, but any phenomena claimed to alter the orb's moment of inertia must be assumed both to have no equal and opposite counterpart to counteract it, but to alter the geoid generally. Furthermore the repeated actions of these tectonic thrusts into the earth must be supposed to be continually accelerating the globe, so that in a world unaffected by decelerating tides we would have to postulate a continual acceleration and increased bulging due to this type of earthquake.

It all seems pretty far fetched, but it becomes easier to understand how many at NASA and NOAA tend to position themselves on the side of Catastrophic Climate Change. 64.50.104.162 (talk) 21:37, 28 April 2010 (UTC)A G Foster
