 * a (prose, spelling, and grammar): b (MoS for lead, layout, word choice, fiction, and lists):
 * 1) It is factually accurate and verifiable.
 * a (reference section): b (citations to reliable sources):  c (OR):  d (copyvio and plagiarism):
 * 1) It is broad in its coverage.
 * a (major aspects): b (focused):
 * 1) It follows the neutral point of view policy.
 * Fair representation without bias:
 * 1) It is stable.

 * a (images are tagged and non-free content have non-free use rationales): b (appropriate use with suitable captions):
 * 1) Overall:
 * Pass/Fail:
 * The article is not too far from reaching GA status but there are a few issues that needs to be addressed before passing. I believe the nominator is capable of improving it further. I have highlighted the issues which needs to be addressed below. Dora the Axe-plorer (explore) 08:06, 9 September 2022 (UTC)

 * The reference Bernard et al. 1997, McNeill et al. 2005 & McNeill et al. 2007 makes no mention of "Egion fault" which is used in the article. I assume you are referring to the "Aigion fault". Is there a reason for the rename? Dora the Axe-plorer (explore) 05:25, 9 September 2022 (UTC)


 * Other studies refer to it by Egion fault, such as Koukouvelas 1998 and Koukouvelas & Doutsos 1996, and even the Egio fault, such as Lekkas et al 1998. Most sources do appear to reference it as Aigion, so I will change the fault name to Aigion. SamBroGaming (talk) 06:01, 9 September 2022 (UTC)
 * Fixed SamBroGaming (talk) 06:03, 9 September 2022 (UTC)


 * There is a large discrepancy in the range of magnitude, I'm talking about the scale here;  6.1–6.6 is an incredibly huge discrepancy. I see you referenced Masood's Nature article to obtain the lowest figure. Can you be so sure the 6.1 in question is measured with the  scale? I'm not sure where 6.6  came from, I assume it's a typo from the USGS event page figure. Dora the Axe-plorer (explore) 05:25, 9 September 2022 (UTC)


 * I must have made a typo as I looked through my references and could not find the 6.6. Fixed in the article now SamBroGaming (talk) 05:46, 9 September 2022 (UTC)
 * The Nature article gave "magnitude 6.1" but is that 6.1? Dora the Axe-plorer (explore) 05:50, 9 September 2022 (UTC)
 * It seems like that magnitude subtype wasn't specified. Remove it unless you can find a figure that provides the subtype. Dora the Axe-plorer (explore) 05:54, 9 September 2022 (UTC)
 * I have removed Masood's paper in nature entirely SamBroGaming (talk) 00:46, 10 September 2022 (UTC)


 * The article provides multiple magnitude and range of depths; can this be standardized by using the ISC-GEM's earthquake catalog (6.5, 15 km depth, 38.408°N 22.278°E)? Most GA articles use the ISC-GEM as their data is considered final. The  and  figures can be mentioned in the article body but for the sake of presentation, remove them from the infobox. Dora the Axe-plorer (explore) 05:25, 9 September 2022 (UTC)


 * I feel like they are presented quite neatly in the infobox but they feel a bit much in the main text. Could I perhaps remove them from the text instead of the infobox? As for the depth, various studies have come up with different depths and I feel that specific scientific studies on the event take precedence over an agency's estimate. SamBroGaming (talk) 05:47, 9 September 2022 (UTC)
 * The infobox shouldn't be cluttered with that many info. Spare the details for the body text. The Ms and Mw figures are frequently referenced in scientific lit. so you may limit to just mentioning these in the article while excluding ML (which has only been featured in one study). Adding too many magnitude figures also causes excessive referencing which doesn't look great. Dora the Axe-plorer (explore) 06:09, 9 September 2022 (UTC)
 * Alright, will remove from infobox and explain better in text. I will remove the Masood citation, however Tselentis 1996 has it as 6.2 as well, so that should still hold up. SamBroGaming (talk) 06:23, 9 September 2022 (UTC)
 * Fixed magnitude, unsure what to do about depth SamBroGaming (talk) 06:26, 9 September 2022 (UTC)
 * If you prefer these scientific studies' results, you will have to use their info consistently and as a whole. These agencies and studies determine the seismological parameters through different methods so results would vary. Nick picking these info wouldn't be wise. Currently you have included a range of focal depths based on multiple studies, that means you have to also include different values into the same parameter if they were also defined in the citations. Eg; if a specific paper's depth was used, follow the epicenter coord given in that paper. Likewise if you gave multiple depths, you have to give multiple coordinates. This is why I advice using the ISC-GEM catalog and I see no evidence that results of a scientific study is superior over that. Dora the Axe-plorer (explore) 07:49, 9 September 2022 (UTC)
 * Is there any way to incorporate the epicenter location of the studies into the article to fit these guidelines then? I see no reason to completely disregard research papers focusing on the event just because it is more convenient to have a single central source. I feel it would defeat the point of being a good article if I relied solely on the ISC-GEM catalogue for this reason. Please tell me if I can go about it some other way.

 * Under Impact header, line 5, can you clarify on what "the sea moved 2–3 m (6 ft 7 in – 9 ft 10 in) closer to land" means? Is it describing a long-term effect ie. land subsidence, or a temporary one like a tsunami? Dora the Axe-plorer (explore) 05:25, 9 September 2022 (UTC)
 * You did this after asking, so thank you. SamBroGaming (talk) 05:50, 11 September 2022 (UTC)


 * The paper says "In Erateini, the sea advanced inland for 2 3 m., in areas covered by fluvial and coastal deposits; no such a case was observed where alpine rock outcropped." I was not very sure how to interpret this, so perhaps you could help me phrase it better in the article. SamBroGaming (talk) 05:50, 9 September 2022 (UTC)
 * It's under the header Coastline changes so clarify that this observation is an example of coastal changes which occurred after the earthquake. The paper (Koukouvelas 1998) has a number of interesting details not mentioned in the article. A lot of the details have been left out and summarized. It would be nice to give further elaboration. Dora the Axe-plorer (explore) 06:20, 9 September 2022 (UTC)
 * Fixed the coastal changes thing, will add more details when I have more time this week. SamBroGaming (talk) 06:30, 9 September 2022 (UTC)
 * I've reworded it a bit. There are more examples given so take the time to include those as well. Dora the Axe-plorer (explore) 06:48, 9 September 2022 (UTC)
 * A lot of sources aren't used to their full extent. The Nature article is one of these; it's about a legal dispute between seismologists over earthquake prediction regarding the event. This earlier Nature article provides some additional info. Dora the Axe-plorer (explore) 07:05, 9 September 2022 (UTC)
 * I can add a controversy section over the controversy surrounding the lack of prediction over the earthquake as well. SamBroGaming (talk) 22:59, 10 September 2022 (UTC)
 * Done SamBroGaming (talk) 05:49, 11 September 2022 (UTC)


 * Response section is sufficiently well written. Dora the Axe-plorer (explore) 05:25, 9 September 2022 (UTC)


 * A bit more pressing is the article's claim on the scientific aspects of the earthquake. The article says that the earthquake "may have taken place along the Aigion fault". I find none of the references supporting this. Koukouvelas 1998 says the earthquake reactivated the fault and generated a surface rupture for 7.2 km. However, McNeill 2007 said that "no historic earthquakes are confirmed on the Aigion fault". Furthermore supported by another paper (it's not used in the article FYI): "In 1995, a magnitude 6.2 earthquake occurred 15 km NNE of Aigion, on a very low dip normal fault. Seismological, GPS and SAR data show that the earthquake is not located on the Aigion fault, but that it caused small coseismic ruptures along the fault". Can you rewrite this part—it appears the Aigion fault isn't the source of the earthquake, however these sources mention a "low-angle normal fault" so stick to that. Dora the Axe-plorer (explore) 07:29, 9 September 2022 (UTC)
 * You are correct in this, and I will fix that portion. It was the large aftershock that took place along the Aigion fault, and I will change the article to reflect that. SamBroGaming (talk) 23:01, 10 September 2022 (UTC)
 * Koukouvelas 1998 actually does say it takes place on the Egion fault. SamBroGaming (talk) 23:22, 10 September 2022 (UTC)
 * Bernard 1997 et al also mentions the possibility of an aigion fault partial rupture; "The very high ground acceleration in Aigion (0.5 g peak acceleration record on the NOA accelerometer) may indeed have induced the observed slip in the shallow part of the Aigion fault" SamBroGaming (talk) 01:30, 11 September 2022 (UTC)
 * @SamBroGaming From my understanding of that quoted source, the strong ground motion caused slip to occur on the fault at a superficial level. Something on the lines of triggered slip perhaps? Dora the Axe-plorer (explore) 01:44, 11 September 2022 (UTC)
 * Fixed SamBroGaming (talk) 05:49, 11 September 2022 (UTC)

Alright, so I believe I have completed everything you have asked for me to fix here. Please let me know if I have missed any of your suggestions, or if more needs to be done to get this article to good article status. Thanks, SamBroGaming (talk) 05:51, 11 September 2022 (UTC)


 * The article is well-researched and an improvement from previously. I've made additional clean ups and copyediting. Reference Lekkas 1998 can be used to further expand to broaden the article coverage in a slightly in-depth manner. After that, I can pass the article. Dora the Axe-plorer (explore) 08:13, 11 September 2022 (UTC)
 * I have added to it as best as I could. SamBroGaming (talk) 08:37, 11 September 2022 (UTC)
