Talk:Subduction tectonics of the Philippines

What does this mean? This isn't the right answer to my question

Message from Charles

1. The preview image can be a bit bigger so that the audience can grab the key concept more conveniently. 2. The first sentence of the introduction can simply answer the question of "what is the subduction tectonics of the Philippines" 3. More terms bluelinked with the subsections in the wiki page can be added to create more linkage between the precise introduction and the following contents. 4. The images of the cross-sections are exceptionally well as they simply and precisely describe the shear partitioning mechanism and the subduction process.--Charlespsml (talk) 14:35, 25 November 2019 (UTC)

Message from Alex

1. I think it is not necessary to mention the author's names when you write the content as the citation has already helped you to do this work.
2. Is there any method to add a citation for GeoMapApp figures?
3. For "Palawan–Central Philippines collision zone", it is possible to describe each collision zones simply (e.g. geology).
4. The content of this page is doing exceptionally well since the contents mostly clear, concise and simple. It is suitable for geology beginners to read and able to develop their geological interest about Philippines tectonics.

Message from Tommy

1. I think it would be great to explain the mechanism leading to northward and southward migration of the trench from Bicol.

2. May I know why continental suturing leads to break-off of plate Y and subsequent subduction of plate Z?

3. You mentioned Philippines is one of the most hazard-prone regions on Earth. It would be great to include a particular geohazard case study to show why it is important to study this subduction system.Makhkugeo (talk) 05:50, 16 October 2019 (UTC)

Comment from Graeme

I would like to see references for the two sections "East-dipping subduction zones" and "West-dipping subduction zones". If references they would then permit an article to get into WP:DYK. ALso for the lead map, please make the writing on the trench labels bigger, some are just readable in the thumbnail, but others are not. Graeme Bartlett (talk) 04:00, 19 October 2019 (UTC)

Message from Helen

1. It will be better if you could enlarge Fig. 3 so that the readers can read the words and symbols more clearly.

2. Fig. 6 presents a very clear mechanism of the spontaneous initiated subduction but it will be good if the materials on Plate X are annotated.

3. Sub-titles can be added for the different hypotheses of Philippine Trench Formation.HelenHYW (talk) 05:39, 21 October 2019 (UTC)

Comment by Ariel

1. It would be great if the "volcanoes of the Philippines" figure could be simplified into simple outline of the Philippine and triangles representing the volcanoes only.

2. It would be great to add a simple geological map showing the spacial relationship of the components you have mentioned, e.g. the trenches, microcontinental blocks, etc. Hkgeo4869 (talk) 05:57, 22 October 2019 (UTC)

3.For the subduction initiation mechanism section, the paragraphs could simplified into annotation and caption for the diagrams. Hkgeo4869 (talk) 06:01, 22 October 2019 (UTC)

Comment from Abraham

Improvement 1

I think the citation should be placed after a full stop or comma. I am not so sure but this is what I saw in other well-developed wiki pages.

Improvement 2

It would be great if the color scheme of the illustration of the shear partitioning mechanism is not that strong.

Improvement 3

The size of the bathymetric profile might be enlarged a bit.

Well done

The overview diagram with the coordinates is very nice. The thickness of the lines is perfect. It looks very clear.

• I'll be claiming this for review and hope to finish within the next few days, but for now, I was wondering if a better hook could be presented here. Right now, it's a little dry and basically discusses a fact instead of highlighting something interesting about the topic. Narutolovehinata5 ^tccsdnew 05:26, 12 December 2019 (UTC)

• There is still an unresolved deletion nomination of the lead image. This DN needs to close before hook can be promoted. -- P 1 9 9  ✉ 16:03, 16 December 2019 (UTC)

• I think this can go forward without the image. --evrik ^(talk) 20:28, 18 December 2019 (UTC)

• Alt1 that four ophiolite belts are recognised in the subduction tectonics of the Philippines?
• Alt2 that ophiolitic belts in the subduction tectonics of the Philippines become progressively younger from east to west?

• I propose Alt1 and Alt2 which may not be so dry. On the topic of the image we are not using it in DYK, and I argue that it is not an infringement. I don't think the nominator looked at the images involved. Just confused the credit. Graeme Bartlett (talk) 11:14, 22 December 2019 (UTC)

The issue now is that ALT1 and ALT2 sound a bit too technical. Maybe the wording could be revised to make them more layman-friendly? Narutolovehinata5 ^tccsdnew 10:43, 23 December 2019 (UTC)

• Should we explain what ophiolite means in the hook? Graeme Bartlett (talk) 23:51, 30 December 2019 (UTC)

Since ophiolite is linked in the hooks, it can be optional. The issue for me here is more that mentioning that these belts exist or that they're getting younger isn't really eye-catching and still feels dry. I think it might be a better idea to try a hook that doesn't involve the ophiolite stuff as it just might be too technical. Narutolovehinata5 ^tccsdnew 00:25, 31 December 2019 (UTC)

• Alt3 that two microcontinents are colliding near the Philippines in a process called subduction? --evrik ^(talk) 05:34, 31 December 2019 (UTC)
• @Narutolovehinata5: --evrik ^(talk) 05:34, 31 December 2019 (UTC)

It sounds okay, but it's unspectacular. Perhaps we can try something as to how the plate tectonics are a factor as to why the region has many volcanoes? Narutolovehinata5 ^tccsdnew 09:03, 5 January 2020 (UTC)

Do the microcontinents also have more hooky names, like "Palawia"? We could probably drop "in a process called subduction". Or describe it:

• Alt4 ... that as the Palawan microcontinent sinks into the planet's mantle, its molten remnants erupt from many volcanoes in the Philippines?
• Alt5 ... that extensive disturbances in the crust supporting the Philippines make it one of the most geologically hazardous regions on Earth?
• Alt6 ... that the Philippines are one of the most geologically hazardous regions on the planet?

(I do think we need to qualify the hazard; parts of Yemen are a lot less safe...) HLHJ (talk) 04:59, 11 January 2020 (UTC)

I think that the alt4-6 would be OK factually, but the reviewer will have to figure out where the article supports those statements! Graeme Bartlett (talk) 04:17, 12 January 2020 (UTC)

ALT5 and ALT6 appear to be mentioned in the lede (with citations, although they seem to be paywalled for me), so it might be good enough for DYK purposes. Considering current events, the timing of this nomination is probably proper. Narutolovehinata5 ^tccsdnew 00:13, 13 January 2020 (UTC)

Note scale. You must be breathing the 2020 Taal Volcano eruption, Narutolovehinata5, when you can't see it; hope it's not too unpleasant, and best wishes for your wellbeing. HLHJ (talk) 19:11, 15 January 2020 (UTC)

• @HLHJ: I'm in Manila right now and won't come home until the weekend, so I was able to avoid the worst. It was really scary though since I could see the plume from my house, and the expressways were full of ash. Narutolovehinata5 ^tccsdnew 00:22, 16 January 2020 (UTC)
  • Nice timing, I hope you've dodged it all. A pyrocumulus punching through the stratopause is spectacular, but from a caldera diameter away... Having your house closed should have reduced the amount of nasties settling inside, too, and the ash corrosion to your cloth, mild steel, and such. HLHJ (talk) 04:03, 16 January 2020 (UTC)
• When CTRL+F-ing, it seems the first ref for the hook (in the lead of the article) only says "All of these trenches are recognized as earthquake generation regions and are natural hazards to the country," and the second ref doesn't use the word "hazard" or "danger" and upon reading doesn't mention potential risks at all   User:Dunkleosteus77 |push to talk  03:37, 18 January 2020 (UTC)
  • Alack, I didn't check the source. It doesn't seem implausible, and if it isn't in the source in some phrasing it may be citable elsewhere; a global geological hazard map, for instance. HLHJ (talk) 05:27, 24 January 2020 (UTC)

• Graeme Bartlett, can you please look into Dunkleosteus77's concerns regarding that hook sourcing? Many thanks. BlueMoonset (talk) 06:11, 28 January 2020‎ (UTC)

• Apologies, Graeme Bartlett; I forgot to sign the previous post (belatedly doing so now with the correct timestamp). The ping should go through this time. BlueMoonset (talk) 17:46, 2 February 2020 (UTC)

• The second ping worked. This bit of the hook "most geologically hazardous regions on Earth" sounds interesting, but when I search for that, I find Nepal, Iran, Kuril Islands, and this very page. So perhaps it is writing to sound senational. so how about this variant?

• alt7... that extensive disturbances in the crust supporting the Philippines produce many hazardous volcanoes and earthquakes?

Text supporting this from the first ref also supports alt4 and this alt7: "Tectonic setting of a composite terrane: A review of the Philippine island arc system":

“ Several arc systems associated with the different surrounding trench systems are found in the Philippines. Interest in these volcanic arcs is brought about by their

associated mineralization, geothermal energy potential, and related natural hazards.

All of these trenches are recognized as earthquake generation regions and are natural hazards to the country

In general, the Philippines is made up of the aseismic Palawan microcontinental block and the seismically-active Philippine Mobile Belt characterized by earthquakes and active volcanoes

No photo is used in this nomination, but the charts used in the article are properly licensed. QPQ requirement is complete. Article has one maintenance tag, and I have a few questions on sourcing and citations below. Multiple hooks are suggested. I will look over each one and post here shortly. Flibirigit (talk) 23:59, 16 February 2020 (UTC)

Outstanding questions

•  Done In the section "Palawan–Central Philippines collision zone", it appears that the introductory sentence and the three listed items may not be cited. Can either of the citations in the subsequent sentences cover these?
•  Done In the section "Volcanic arcs", there is a [clarification needed] tag to resolve.
• In the same section as above, I am unsure of the source of the final sentence in the paragraph. Maybe it's the previous citation?
•  Done There are a few paragraphs that do not end in a citation. While this is not a DYK failure, it is not clear what it the source of the ending sentences. Please see the sections "Late Oligocene – Early Miocene" and "Formation of Philippine Trench".
•  Done In the section "Tectonic hazards in the Philippines", there is no citation in the first subsection, "Volcanoes".
•  Done The use of diagrams is very thorough and adequate. I am curious if any consideration was given for photo of physical features such as volcanoes, trenches, et cetera. This is not a DYK criteria, but a general question.
•  Done Usually when multiple citations appear, they are in numerical order, such as [1][2][3]. This is not a DYK criteria, but a general suggestion.

I will post comments on the hooks shortly. Flibirigit (talk) 23:59, 16 February 2020 (UTC)

Hook comments

• I agree with the above comments that ALT0, ALT1 and ALT2 are too dry and technical to be appealing to a broad audience. I have struck those hooks. I will analyze the remaining proposed hooks ALT3 to ALT7. Flibirigit (talk) 00:28, 17 February 2020 (UTC)
• ALT3 would be interesting to a broad audience, and is factually correct. I do not see where it is explicity cited in the article though. The final sentence of the section "Palawan Microcontinental Block" is the only place in the article where I can find microcontents and subduction mention in the same sentence, but its not a great match to cite ALT3. The caption for the first image used in the article implies what is mentioned in the hook, but there is no citation in the caption. Flibirigit (talk) 00:48, 17 February 2020 (UTC)
• ALT4 is somewhat interesting, and might appeal to a broad audience. It seems factually correct, but I cannot find any statement in the article that says X leads to Y with respect to the Palawan microcontinent and volcanoes. This could be revisited once the sourcing is more clear in the "Volcanoes" section as mentioned in the questions above. Flibirigit (talk) 01:00, 17 February 2020 (UTC)
• ALT5 is interesting and would appeal to a broad audience. The hook uses the word "disturbances" which does not appear in the article, nor is defined. Citations for the hook are behind a paywall, and would be accepted by AGF. Flibirigit (talk) 01:55, 17 February 2020 (UTC)
• ALT6 is interesting and would appeal to a broad audience, and is the best hooks suggested. My only concern here is the wording "most geologically hazardous regions on the planet" in the hook, versus "one of the most hazard-prone regions on Earth, which is frequently affected by volcanic activities, earthquakes and tsunami" in the introduction. It would be best to use more similar wording, specifically the word "geologically". Citations for the hook are behind a paywall, and would be accepted by AGF. Flibirigit (talk) 01:55, 17 February 2020 (UTC)
• ALT7 is interesting and would appeal to a broad audience. I cannot find any statement in the article that says X leads to Y with respect to "extensive disturbances in the crust supporting the Philippines" and "produce many hazardous volcanoes and earthquakes" The hook uses the word "disturbances" which does not appear in the article, nor is defined. This could be revisited once the sourcing is more clear in the "Volcanoes" section as mentioned in the questions above. Flibirigit (talk) 01:55, 17 February 2020 (UTC)
  • I have added references and a clarification. For selection of diagrams I suppose you can ask Karen here: user talk:LkwkarenHKU — there probably are photos of volcanoes available. As for trenches, any photo would be a black rectangle, as it is dark down there! I suspect very little photography in the ocean trenches — but really I don't know what's available. Graeme Bartlett (talk) 11:43, 17 February 2020 (UTC)
    • Thanks for the updates. Just one question remains outstanding for sourcing. I did not see any changes which addressed the hook comments listed above. Flibirigit (talk) 23:19, 17 February 2020 (UTC)
      • I have added text to the last sentence in the lead to cover alt7. Note the previous discussion that I was not going to try to prove the other hooks, as some are not factually correct. Graeme Bartlett (talk) 04:56, 24 February 2020 (UTC)
        • ALT7 is now properly cited, mentioned inline, and verified with the sources. A question still remain on the sourcing in the section "Volcanic arcs". Specifically the sentence, "Dating arc-derived rocks can constrain the timing for trench formation along with the tectonic evolution in Cenozoic". Cheers.
