French earthquakes March 20, 2019

lt’s not at the USGS. :/--5.33.0.77 (talk) 15:39, 20 March 2019 (UTC)

Edit: lt’s at the USGS, but at a lower magnitude, and deeper.--5.33.60.109 (talk) 18:53, 16 July 2019 (UTC)

SMay 6, 2019 Papua New Guinea earthquake s

130+ houses and a school destroyed, but no casualties? Really?--5.33.0.17 (talk) 23:12, 9 May 2019 (UTC)

I need help!

Could you guys help me. I'm trying to add a recent earthquake that struck Panama.

I have everything except the multiple separate boxes.

If you could respond or fix it for me I would be rally happy.

She-Hulka

Thank you for whoever helped me

l think that l have had (a) problem(s) adding new earthquake(s), too. You forgot to sign your comment.--193.163.223.192 (talk) 23:35, 13 May 2019 (UTC)

Aftershocks

How often do earthquakes not have after- or foreshocks? The May 6, 2019 Papua New Guinea had no after- or foreshocks, may be worth to write that.--5.33.0.37 (talk) 01:29, 13 May 2019 (UTC)

Only a relatively small proportion of earthquakes have foreshocks. As to aftershocks, they are far less common with intermediate and deep earthquakes, compared to shallow earthquakes (<100 km) - see here, page 238. That information should probably go in our aftershock article. Mikenorton (talk) 17:41, 27 May 2019 (UTC)

As an example, an earthquake with a depth of 99.99 km is not a shallow earthquake.--5.33.15.80 (talk) 08:07, 28 May 2019 (UTC)

The paper that I linked to above says that only 5% of earthquakes deeper than 100 km have aftershocks, which is why I quoted that number. The normal cut-off for shallow earthquakes is 70 km, so that would mean that any earthquake with a hypocentral depth of 69.99 km would be regarded as shallow-focus. Mikenorton (talk) 08:28, 28 May 2019 (UTC)

69.99 km deep is pretty deep.--83.75.197.251 (talk) 16:51, 31 May 2019 (UTC)

It's all comparative - the normally accepted ranges are 0–70 km (shallow) 70–300 km (intermediate) >300 km (deep) - the deepest known earthquake was more than 700 km down. Compared to 700 km, 69.99 km is shallow. Mikenorton (talk) 17:16, 31 May 2019 (UTC)

The deepest earthquakes may have been 888.0 km deep.--83.75.197.251 (talk) 18:24, 31 May 2019 (UTC)

Edit summaries

Hardly any of the edits to this list are using edit summaries - MysteryMrHandsome, Lorent33, Osowix, Dwianto08, José A. VEN, She-Hulka - this means you. You should always use edit summaries, no matter how trivial the edit seems to you, because it helps other editors who watch this page have some idea what's going on. Mikenorton (talk) 10:16, 1 June 2019 (UTC)

Okay sir, noted and thanks for telling. MysteryHandsome (talk) 10:18, 1 June 2019 (UTC)MysteryHandsomeMysteryHandsome

Thanks to all that are now using edit summaries. Mikenorton (talk) 12:31, 1 June 2019 (UTC)

Ridgecrest earthquake date?

the Ridgecrest earthquake mainshock happened on July 5 at 8:12 (ish) pm PST, so should we put the 5th or 6th? I think we should put the 5th since that was the date in the area where the earthquake happened. FlappyBird73 (talk) 19:48, 7 July 2019 (UTC)

As the lead section says "All dates are listed according to UTC time". Mikenorton (talk) 22:09, 7 July 2019 (UTC)

oh I didn't notice that, sorry. Thanks! FlappyBird73 (talk) 16:04, 8 July 2019 (UTC)

l do not think that California currently follows the pacific standard time.--83.73.253.26 (talk) 22:08, 8 July 2019 (UTC)

New earthquake in Iran

M 5.1 earthquake 28km SE of Masjed Soleyman Iran🇮🇷 kills one. Dorah the Axe-plorer (talk) 10:05, 8 July 2019 (UTC)

lt is not at the USGS, so the question is, did it happen?--83.73.253.26 (talk) 22:46, 8 July 2019 (UTC)

Sorting columns

They do not sort correctly.130.228.22.187 (talk) 23:04, 23 July 2019 (UTC)

Which columns are you referring to - all the ones that I've tried (not exhaustive) seem to sort properly. Mikenorton (talk) 00:14, 24 July 2019 (UTC)

’By magnitude’-->Magnitude, depth and date. There may be errors in/with all the columns in that section. Also, sorting columns do/does(?) not work on any Wikipedia article and/or page in mobile view. 130.228.22.187 (talk) 14:15, 28 July 2019 (UTC)

OK, that's fixed now - a few of the parameters had been added not using number or date sorting templates. I have no idea why mobile view does not support sorting. Mikenorton (talk) 07:47, 1 August 2019 (UTC)

South Hutchinson, Kansas earthquakes

There were 2 very similarly-sized earthquakes there, with 2 days in between.--83.74.89.97 (talk) 21:58, 31 August 2019 (UTC)

Sao Tome & Principe earthquake

I don't think that being the largest in an arbitrarily defined western Africa (see Western Africa, which doesn't include the epicentral area) makes it notable enough for inclusion. Mikenorton (talk) 13:16, 20 December 2019 (UTC)

Mikenorton (& @Lorent33: since this might be relevant to you?) well I think perhaps this is a good time to discuss exactly what the "notable for other reasons" descriptor is, then. I don't think at any point over the last several years that this earthquake list group(?) has been upkept that a single earthquake under 6th magnitude with no casualties or notable damage has been included once. Surely if we can go for several years on end without including a single earthquake "notable for other reasons" then that descriptor shouldn't be included there? Or at the very least, clarified to include what exactly counts as "notable for other reasons" when clearly it's otherwise quite rigidly defined what makes an earthquake qualify to the list otherwise. exoplanetaryscience (talk) 19:14, 20 December 2019 (UTC)

It's not spelt out. I think that if there is a consensus of editors that an earthquake is sufficiently notable (for whatever reason) then it would be included. I opened a discussion here for the purpose of checking on consensus, rather than just reverting. Mikenorton (talk) 12:15, 21 December 2019 (UTC)
