Talk:1992 Landers earthquake

message: Why is there not any mention of the Petrolia series of Earthquakes which also occurred in 1992. This occurred on April 25, 1992 and was a magnitude 7.1. This would make Landers the largest California earthquake to happen in a few months. Not 40 years. The Petrolia earthquake was in fact the largest to occur since the 1952 Kern County event.

message: The aftershocks section repeatedly emphasized that the Big Bear earthquake was completely unrelated to the Landers earthquake. However the reference cited said that they were related. I corrected the section to agree with the reference. Rsduhamel (talk) 08:19, 1 January 2009 (UTC)
thread_title:  Aftershocks 

message: Reports of the 1992 Landers earthquake came from 1,000 miles away in distant places like Albuquerque and Seattle, where residents find window blinds rattle in a soft motion and swimming pools mysteriously splash into the sidewalk. I believe the richter scale for this one wasn't completely accurate, whether it was M7.3 or 7.6, the quake's magnitude was strong enough to be felt or detected in 12 western US states, 15 Mexican states & 3 Canadian provinces. + 71.102.7.77 (talk) 14:15, 27 February 2010 (UTC)

message: I think an article about a specific significant earthquake should mention displacements associated with the quake and the aftershocks.  What land was moved, in what directions, and by how much? SlowJog (talk) 17:28, 14 March 2011 (UTC)

message: When the quake was first reported in the news, it was described as 7.7 or 7.8.  The rating was still changing months later.  According to this news report by the LA Times in 1993, the Landers quake was the strongest for 1992 being rated at the time at 7.6 based on "complete reports from 39 seismological stations throughout the world."    The article seems to indicate the quake is now rated a 7.3.  Does anyone know the basis for the downgrade?  It seems strange that there is a .3 downgrade after months of analysis of "complete reports from 39 seismological stations throughout the world. RonCram(talk) 17:13, 8 August 2012‎ (UTC)
:I was in San Diego when it happened, and remember it was reported as a 7.4 at some point.  See also this article https://www.latimes.com/archives/la-xpm-1992-06-29-mn-890-story.html.  As such, I too am curious when and why it got downgraded to 7.3. 131.89.195.71 (talk) 15:52, 4 October 2023 (UTC)
replies: text: Earthquake magnitudes are regularly recalculated. The 7.3 Mw is attributed to the California Integrated Seismic Network: Southern California Seismic Network (Caltech, USGS Pasadena, and Partners). Soon after the event there were a range of magnitudes quoted, but looking at the scientific papers that were published within the first few years, these mostly showed 7.3 Mw and, more recently than that, only the 7.3 value. The initial high values were probably not on the moment magnitude scale, either surface wave magnitude  or Richter magnitude , which are less accurate for larger earthquakes.

message: It reads as rather flowery, a bit like a bad newspaper article.  Can someone take a look at this?  
Generally all I do to wiki articles is vandalize them, but this is actually poorly written and not up to wiki standards.

thread_title:  Tone of page is conversational, shouldn't this read less like prose and more like an encyclopedia entry? 

message: The claim that this is the "largest in 40 years" seem to consider the 1952 Kern County earthquake the previous largest one (also magnitude 7.3).  However, the 1959 Hebgen Lake earthquake has a higher magnitude and occurred later. DHN (talk) 23:06, 26 February 2017 (UTC)
replies: text: Yeah, that's been bothering me for some time. Thanks for mentioning it. I went ahead and removed it. Dawnseeker2000 23:53, 26 February 2017 (UTC)
