# Talk:Kīlauea

So an editor here is calling this a new eruption when in reality its the resumption of the summit eruption since HVO didn't declare the eruption after it paused in May over
Am i right or wrong HavocPlayz (talk) 11:54, 30 September 2021 (UTC)

I think you are wrong. The USGS HVO uses the rule set by the Smithsonian Global Volcanism Program that any volcanic activity that occurs more than 90 days after the end of a previous eruption is regarded as a new eruption, see, for example, https://www.usgs.gov/center-news/volcano-watch-ninety-days-no-lava-a-milestone-k-lauea-s-2018-eruption and https://volcano.si.edu/gvp_currenteruptions.cfm. The previous eruption of Kilauea ended in late May 2021, see https://www.usgs.gov/volcanoes/kilauea/recent-eruption?qt-science_support_page_related_con=0#qt-science_support_page_related_con . Therefore, activity after late August 2021 is a new eruption, see e.g.
https://volcanoes.usgs.gov/hans2/index/notice/DOI-USGS-HVO-2021-08-31T13:29:29-07:00 and https://volcanoes.usgs.gov/hans2/index/notice/DOI-USGS-HVO-2021-09-29T18:28:16-07:00 . It is not yet listed as a new eruption by the Smithsonian GVP because their database of eruptions is currently as of 19 August 2021, see https://volcano.si.edu/ and their most recent weekly activity report https://volcano.si.edu/reports_weekly.cfm covers the period to 28 September 2021, the day before the new eruption started at Kilauea.

I thought the rule was like 5 months but it was a vague memory.thx for the clarification HavocPlayz (talk) 16:29, 30 September 2021 (UTC)

As USGS states: Kīlauea volcano has been erupting from a single vent in the western wall of Halemaʻumaʻu crater. As of this morning, December 5, 2021, the rate of eruption continues to be very low and any activity is difficult to view given the current weather. All recent lava activity has been confined within Halemaʻumaʻu crater in Hawai‘i Volcanoes National Park.
Summit Observations: Lava effusion from the western vent decreased significantly Friday afternoon, accompanied by a decrease in volcanic tremor. Both remain low this morning. A minor deflationary tilt signal recorded on summit tiltmeters that began on Friday afternoon has stabilized and there was little change in tilt over the past 24 hours. The most recent measurement of Sulfur dioxide (SO2) emission rates on November 29, 2021 was approximately 1200 tonnes per day obtained. However, continuous instrument measurements indicate that SO2 emission rates have decreased with the change in eruption rate. Earthquake activity remains below background.
@Aoi: Although it's too early to tell if it's too early to know if it's just a pause or if the eruption is over, the earthquakes remained deep, but at a similarly low rate, I believe the eruption will come to an end. I don't know much.
I think the link would help: see here. More at Volcano Updates.

I don't know much either. There was deflation at the summit on Friday was replaced by inflationary tilt within the last 24 hours or so, but the eruption hasn't resumed so there's that. However, the update states that this is the "fourth such pause since the eruption began on September 29 and a return to earlier rates of eruption is possible." We don't even mention the other three pauses in the article. That said, I think it would be fine to mention the pause in the article itself, but I don't think we should add or change a date in the infobox unless something more definitive comes out of USGS. I believe during the December 2020 eruption, we waited until USGS issued a volcanic activity notice stating "Kilauea is no longer erupting"[1] before changing infobox dates.

The vent has reactivated is again supplying lava to the lake. The pause wasn't noted outside of the daily VNS reports by USGS and it wasn't widely covered by other sources, so I no longer think we need to address it in the text now that the eruption has resumed.

### 2023
Seeing as the latest summit eruption has ceased as of March 7, nearly two weeks ago, I have briefly noted this fact with an AP-sourced update to the article body, lede and infobox. This information will be helpful to those wishing to visit and view active lava, which is currently not possible, and other readers seeking accurate information as to the status of the volcano. It may be a pause, or the end of the eruption, but either way, this fact should be included in the article, in my view. Cheers! Jusdafax (talk) 13:39, 19 March 2023 (UTC)

Since the summit again active is after a three month pause, I have created a 2023 subsection. Jusdafax (talk) 03:29, 8 June 2023 (UTC)
I have now updated the 2023 subsection, article lede and infobox to note the latest pause in the eruption. Jusdafax (talk) 18:41, 20 June 2023 (UTC)

@LightandDark2000: I removed some of the links you re-added to the article for the following reasons:

Live webcam of Halema`uma`u Crater -- I removed because the link is obsolete. The link redirects to the main HVO webcam page.
Littoral lava fountains at ocean entry 18 and 21 Aug 2008 -- I removed because it doesn't link to a video of "littoral lava fountains at ocean entry 18 and 21 Aug 2008". It links to a YouTube user profile page. Even if it did link to a specific video, I don't see adding anything useful to the article as I believe the HVO website already contains a number of videos of littoral lava fountains.
Kilauea Visitor Center -- I removed per WP:ELPOINTS, item #3 try to avoid separate links to multiple pages in the same website, as the main NPS HAVO page is already linked. (Also, strictly speaking, this article is about Kilauea the volcano, not Kilauea the park.)
Hawaiian Volcano Observatory's Kīlauea eruption update website (updated daily) -- I removed per WP:ELPOINTS, item #3 try to avoid separate links to multiple pages in the same website, as the main HVO Kilauea page is already linked, and that page contains a quick and easy-to-find link to the eruption update page.

The Hawaiian Volcano Observatory's website now characterizes the January 2023-March 2023 activity within Halemaʻumaʻu as a separate eruption from the September 2021-December 2022 activity. See this summary of the recent summit activity. Similarly, on this page, HVO notes that the activity that began on January 5, 2023, occurred from different vents in a different part of Halemaʻumaʻu as the 2021-2022 activity (specifically, the more recent eruption vents were on the eastern part of the crater while the earlier eruption was from vents in the western part of the crater). Aoi (青い) (talk) 01:01, 12 May 2023 (UTC)

However, in contrast, the Global Volcanism Program classifies the March 2023 activity as a second episode of the September 2021 eruption, rather than a separate eruption: [2]. Aoi (青い) (talk) 22:04, 17 May 2023 (UTC)

Just found this on the USGS website, there was a recent update this morning stating that a new eruption has occurred. Can someone smart update this page? 137.119.67.217 (talk) 15:21, 7 June 2023 (UTC)

Thanks to Aoi for reflecting this in the info box, mad respect 137.119.67.217 (talk) 15:28, 7 June 2023 (UTC)

In this diff, I removed the following statement from the lead: 

In connection with the 2018 lower Puna eruption the Hawaiian Volcano Observatory predicted that a catastrophic collapse was "extremely unlikely".
I removed it because (1) there is no other discussion of a "catastrophic collapse" in the lead so it really wouldn't be clear to a casual reader what the context of such a collapse would be, and (2) expanding the lead to include the necessary context seemed to me to be WP:UNDUE.
Perhaps this statement and the reference could be integrated into the body somewhere, but it wasn't clear to me exactly where it would go. There is a short statement on the Hilina fault system in the article, but the section does not go into the "catastrophic landslide" theories that have circulated on social media. If I recall correctly, there used to be some discussion of this in the article but, if this is true, the discussion was removed at some point. Aoi (青い) (talk) 20:29, 3 June 2024 (UTC)
