I felt it in central San Diego, the worst earthquake i've felt here so far (since 1998). There was no damage, but the whole house shook fairly violently for about 40 seconds. - Monz ( talk) 23:47, 4 April 2010 (UTC)
I know the event was felt in CA, but is the "California earthquake" template appropriate, or should it be removed? I am thinking it does not apply here so I will remove it. Please add it back if there is precedent to do so. 72.220.169.176 ( talk) 00:15, 5 April 2010 (UTC)
The following paragraph was reverted out of the article:
In addition the above aftershocks, there were more than 25 earthquakes of magnitude 3.0 or greater in southern California and northern Baja California in the two hours immediately following the main earthquake (see map below and right). Seven of these earthquakes were of magnitude 4.0 or greater. The majority of them were centered on an area about 40 miles to the northwest of the main earthquake. The rest were scattered over a wide area of the southern California desert, as much as 100 miles from the main earthquake. Seismologists have not yet announced what relationship, if any, these earthquakes have to the main earthquake.
The explanation was "Removed paragraph with no source. If a citable source refers to the 40 earthquakes we can cite it."
Citing the source ([ [2]]) is problematic because it is a dynamic map that will no-longer have the information after one week. Instead, I uploaded a snapshot of the map and referred to it. Does anybody have a suggestion on how to include this information in the article? There is no caption pointing out how many of the 137 earthquakes on the map are of what magnitude. You have to look at the map and the legend and count for yourself. Rsduhamel ( talk) 03:21, 5 April 2010 (UTC)
Thanks but that source is nothing more than a reporter making original research of his own. The USGS has made no statement that I can find on the activity other than the main earthquake and aftershocks in the immediate area of the epicenter. The reporter must have counted squares on the map.
For what it's worth, here are some facts that I cant weave into the article because I just don't have time to dig around through my library or the web to cite sources. Pointing to maps and other graphics automatically generated by the USGS will be considered OR. The epicenter is where the earthquake begins, not necessarily the location of greatest shaking. The greatest shaking for this quake extends for over approximately 60 miles to the northwest from the epicenter along the Laguna Salada Fault into the US. The shaking was severe to violent (USGS terminology). Only distance from heavily populated areas prevented major loss of life. Now, here's some real OR. Most of the aftershock activity (but not the largest aftershocks) is centered on an area 50 miles from the epicenter, near the US-Mexico border. I'm going to stick my amateur neck way out and predict that there was a surface rupture along the Laguna Salida Fault. I say this for these reasons: Major quake, shallow, severe shaking over a long part of a fault and the area is known for surface ruptures from relatively small quakes. This quake was stronger than the 1940 Imperial Valley quake, which produced horizontal displacement of up to 10 feet. I'll be keeping an eye out for reports. 68.7.140.136 ( talk) 12:45, 5 April 2010 (UTC)
This article could really use a beachball diagram ( focal mechanism). Hamsterlopithecus ( talk) 13:49, 6 April 2010 (UTC)
I just noticed that the USGS has updated the map and list of earthquakes ( http://quake.wr.usgs.gov/recenteqs/Maps/116-33_frames.htm). They now show that the main shock was followed by a magnitude 6.6 aftershock 30 seconds later, 46 miles to the northwest of the main shock. This was a major earthquake in its own right. I can't add this to the article because extracting the information from the map and/or the list would be original research. Rsduhamel ( talk) 20:00, 7 April 2010 (UTC)
It was definitely there. Wish I had saved the page just because. It's gone now. For what it's worth. They showed a 5.1 right at the El Centro airport 1/2 hour after the main shock. Then it was gone, then it was back, then it was gone for good. I guess they are still figuring this one out. Rsduhamel ( talk) 23:30, 7 April 2010 (UTC)
It appears that the quake has been officially named the Sierra El Mayor earthquake. See this page:
Rsduhamel ( talk) 22:27, 8 April 2010 (UTC)
I moved it back, the earthquake is better world know as the prior name, also added this sentace (a.k.a. 2010 Sierra El Mayor earthquake, 2010 Easter earthquake). Not so sure about the last one, if so, 2010 Pascua earthquake will be added as "aka" name.-- Jcmenal ( talk) 00:48, 9 April 2010 (UTC)
The earth moved again today at about 10:30 am. It felt more like an aftershock, there were separate shocks. It felt the same as in Easter (6.9 here in Tijuana), with the difference being that it lasted less than 20 seconds. 201.160.231.1 ( talk) 00:55, 23 May 2010 (UTC)
The 2010 Ocotillo earthquake is a stub describing one of the aftershocks, which is unlikely to be expanded any further. I think that some of the information in that article should be moved here and a redirect placed to this article. Mikenorton ( talk) 21:09, 17 June 2010 (UTC)

We have three choices for intensity information; all supplied by the USGS:
One thing that supports the selection of VII (Very strong): There are videos that show the intensity of shaking from this event. In my personal experience living in California and working with these articles, I would agree that what they show aligns with intensity VII and not intensity IX. Also, the effects of the shock would probably be a bit more dramatic if the intensity truly reached Violent. Dawnseeker2000 00:26, 31 January 2020 (UTC)
