Former good article nomineeEarthquake was a Geography and places good articles nominee, but did not meet the good article criteria at the time. There are suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

Edit request[edit]

Under Earthquake Fault Types, third paragraph, "which may break in one go are approximately 1000 km." Not sure "one go" is proper nomenclature.--165.235.122.19 (talkcontribs) 16:32, 24 December 2014‎ (UTC)

Flood induced earthquakes[edit]

I would like to add to Causes section: "Flood induced" I would like add to "Contents" section: "1.8 Flood induced" Final Text to add

Flood Induced Earthquakes[edit]

Floods may trigger a seismic zone fault failure as the flood mass moves over a fault such as the New Madrid Seismic Zone near the Mississippi River, see Flood triggering of earthquakes for details.

I'll build the "Flood triggering of earthquakes" page tomorrow.

Asteroid induced earthquakes[edit]

Would the ground motion caused by an asteroid impact (e.g., Chicxulub) be considered an "earthquake"? I ask, because the Wikipedia article on Chicxulub Crater says "colossal shock waves would have triggered global earthquakes and volcanic eruptions.[28]" — Preceding unsigned comment added by Trasmuss (talkcontribs) 22:40 23 January 2018 (UTC)

Sure, why not? Such events are not tectonically caused, but when the earth quakes does it make much difference what the cause is? Just last week bolide burst over Michigan (?), which someone reported as causing a magnitude 2 quake.
BTW, when adding a comment please 1) add it to the bottom of the discussion (clicking on the "New section" tab will do that for you), and 2) sign it with the "four tildes" (~~~~). ~ J. Johnson (JJ) (talk) 23:10, 23 January 2018 (UTC)
On the other hand!! I found https://sciencealert.com/january-2018-michigan-bolide-fireball-richter-scale-recording, quoting someone that: "The meteor did NOT cause an earthquake. It registered on the Richter scale as a measurment that would be equal to a 2.0 event." Which can lead back to the question of whether an earthquake is the quaking of the earth, whether it is magnitude 2 or magnitude 9, or a certain kind of event that causes the quaking. ~ J. Johnson (JJ) (talk) 04:10, 25 January 2018 (UTC)

@Trasmuss: I have just reverted your edit with the edit summary "Added "asteroid impacts" per note on discussion page". What is this "per note"? Where have we discussed adding this very trivial item? You asked a question, and I referred that back to "the question of whether an earthquake" is the phenomena of the earth quaking, or the event that causes it. Regardless how that might be resolved, it seems to me that "asteroid impacts" are so rare as to be trivial, not warranting mention. ~ J. Johnson (JJ) (talk) 01:42, 30 January 2018 (UTC)

Not being a geophysicist, it seems like earthquakes are a phenomenom caused by multiple types of events. But in most of our risk analyses, catastrophic rare events may have a greater impact than the cumulative effects of smaller, mundane events. I don't think one can characterize a rare catestrophic event as trivial. Todd Rasmussen (UGA) 16:15, 11 February 2018 (UTC) — Preceding unsigned comment added by Trasmuss (talkcontribs)

In first section, second paragraph, change "earthquakes manifest themselves by shaking and sometimes displacement of the ground" to "earthquakes manifest themselves by shaking and sometimes displacing the ground" as a strictly grammatical correction. DavidPera (talk) 20:41, 17 May 2018 (UTC)

A small edit[edit]

In the topic of <References>, 48 of item, is 'global' instead 'gobal'.61.158.149.231 (talk) 16:19, 3 November 2018 (UTC)

Still me[edit]

<References>'s No.55, the year of this earthquake is 1964 instead 1946, the 1946 is in the Aleutian Islands. By the way, did I correct in type there?61.158.149.231 (talk) 16:39, 3 November 2018 (UTC)

Thanks for pointing those out, both fixed now. Mikenorton (talk) 18:11, 3 November 2018 (UTC)
