Misc. edit

merge with pryroclastic rock

also the redirect from TEFRA should be changed since this is an acronym for Tax Equity and Fiscal Responsibility Act of 1982

Created TEFRA as redirect for you, if you're gonna use an acronym then cap it. Removed irrelevant see also link, why would anyone type in tephra looking for that? Vsmith 23:23, 12 January 2007 (UTC)Reply

non-silica rich tephra edit

Since when is tephra only a product of high silica magmas? I'm sure explosive eruptions can occur when basaltic magma makes contact with water during a submarine eruption. Black Tusk (talk) 04:40, 6 November 2008 (UTC)Reply

Etymology section #3? edit

Usually we tend to put etymology within the overview or directly after it. I don't think I've ever seen it so far down. Warmest Regards, :)—thecurran Speak your mind my past 15:16, 7 December 2015 (UTC)Reply

Following the eruption 19 March at 20:45 at a location called Geldingadalur, in a valley 4.7km inland from the southern coast of the Reykjanes peninsula Iceland. I wanted to ask the same question. What is the etymology of 'TEPHRA'? — Preceding unsigned comment added by Myrddin55 (talkcontribs) 10:27, 20 March 2021 (UTC)Reply

Added New Sections edit

Hi everyone,

I expanded the lead. I added 3 sections titled: 1)Environmental Impacts, 2)Disciplines and the Fossil Record, and 3) Volcanoes (it describes a couple of famous volcanoes from each continent). Feel free to expand the sections. Mikabella95 (talk) 23:35, 6 May 2020 (UTC)Reply

Central America (part of North America) not mentioned edit

Central American volcanoes are not mention, although they have played an important part in world history. The 540 Ilopango eruption contributed to the declines of the eastern Roman Empire and the Sassanid Empire and to the Arab conquests of the 7th century.
