Talk:Nabro Volcano

recent earth quakes and volcano activity
Dear wikipedians,

The volcano region was recently shaken by few earth quakes. According to USGS reports Event ID are 1.usc00045f9, 2.usc00045p7, 3.usc00045vg, 4.usc00045xc are possible to trigger the volcano activity. Any one get valuable information about the event, please update it. Thanks in advance. Gnuismail (talk) 21:29, 12 June 2011 (UTC)
 * Sources are very scarce for unknown reasons and public reports will likely be hard to come by. Additionally, the media is getting confused with the nearby Dubbi Volcano (despite satellite images clearly showing it's Nabro) and stating that Dubbi erupted. Hopefully they'll figure it out soon.

geology?
Could someone improve the English of this section? Can't understand it at all. — Preceding unsigned comment added by 69.72.27.186 (talk) 08:39, 25 June 2011 (UTC)

Introduction- the big picture
Could someone with a good atlas or broadband connection put in the introduction: how far from the coast of the Red Sea? how far from Djibouti and Asmara (or someplace nearby in Ethiopia)?69.72.27.186 (talk) 09:01, 25 June 2011 (UTC)

Merge needed
Since this volcano has not erupted in eons, and there are few, if any, humans affected on the ground (and zero who will ever see these articles) the 2011 Nabro eruption should be merged into this article. Additionally, both articles are very short and both cover exactly the same material to almost the same level of detail. Any objections? Speciate (talk) 22:11, 28 June 2011 (UTC)


 * And a second minor objection that the 'two smaller eruptions' reported in afambo and sireru areas are presumably not from Nabro. So I'd suggest more information is needed before making the merge. But if you're feeling enthusiastic there is enough space on the Nabro page for now I guess, depends how long it lasts. If the eruption continues for a year or so then just having the 'headlines' in the nabro page with may well prove to be tidier.EdwardLane (talk)


 * Agree with Speciate about merging the 2011 Nabro eruption into this article. I don't understand the reasoning of the person above me, saying there is no hurry to merge because things are still ongoing. It should be the other way around. When this eruption began, details should have been posted on the volcano page and - if and when it becomes a major event or too much for the Nabro page - then a new page should be made for it. The result is now that we have a tiny Nabro article and a longer eruption article, which should be cleaned up. Michael5046 (talk) 13:51, 2 July 2011 (UTC)


 * Sorry I forgot to sign the earlier comment (now fixed). My reasoning (perhaps I'll admit flawed reasoning) was that there really ought to be a fair bit more info in the nabro article about the nabro volcano in it's own right.
 * The eruption in 2011 is in itself an interesting event given the hitherto 'extinct' nature of the volcano, and given that the eruption already has an amount of stuff on it that does not really pertain to nabro - air traffic disruption, casualty figures etc, I'd have thought those ought to be in an article about the 2011 eruption, with a link to that (setting a system in place for any subsequent eruptions) from the main nabro article.
 * You may be correct that the 'recentism' of wikipedia means that any pre holocene information about Nabro will probably never get written, and there may be no future eruptions. So yes it's probably fine if you want to merge all the stuff in without losing any significant content. I'm still not clear (due to the lack of sources I can find on the web) whether the sireru/seriru and afambo eruptions are actually from nabro (in which case including them in the 'nabro' article might be misleading - perhaps under the Bidu volcanic complex?) - the names/geography of the region seem to be 'not well defined'.

General eruptive history stuff VEI 7
This looks like a good overview and seems to suggest that Nabro/Mallahle complex had a VEI 6 (or even 7?!!) eruption sometime in the quaternary period.

"A very large eruption or eruptions in the past is evidenced by the presence of extensive ignimbrites, which the authors believe are ‘associated with collapses of both Nabro and Mallahle that formed the present day calderas’ (103). The age of these ignimbrites is unknown, but their spectral characteristics and state of preservation suggest their creation in a single eruptive sequence. The present-day ignimbrites cover an area of ~600 square kilometres, with a bulk volume tentatively estimated at 20 cubic kilometres. Prior to erosion of course a much greater bulk must have been present: the combined ignimbrite outcrop today lies within a 30 km radius of Mallahle, and the authors propose that if there was originally a single ignimbrite sheet extending this distance with a mean thickness of 40 m, the eruption magnitude may have exceeded 100 cubic kilometres (bulk volume)"

OK this article looks to flesh out a bunch more geology for Nabro and the perhaps surprising lack of magmatic connection to the adjacent Mallahle EdwardLane (talk) 21:18, 23 December 2015 (UTC)
