I dabble in volcanology a bit, kinda follow what volcanoes are doing, and even made a website about them! Personal account.

Four more volcanoes this week were unable to convince me, and other volcanologists over the past 40+ years, that they were actually active in the Holocene. Had to relegate them to Pleistocene status. It's a tephra job, but I enjoy doing it.

Global Volcanism Program | Has volcanic activity been increasing? Answers to commonly asked questions about Holocene volcanoes and their eruptions based on data from Volcanoes of the World

We are planning to update this FAQ page next year. An eruption duration graph will probably be included, so I've been working up similar plots. A better (but not perfect) timeframe is since 1960, and use months instead of days.

If official reports from your agency give a range (say 400-600), don't just say 600 to news media. Also, geologists should remember to convert 14C "years before present" numbers to calendar dates, at least for the last 2,000 years. The 1950 baseline is 75 years ago, creating confusion in the press.

"It was a dark and stormy night. Lightning flashed in the distance as the air rumbled around me." The rest is just editing.

Improved satellite imagery compared to 20 years ago clearly shows that those "dark fresh lava flows on glacial moraines" are just more recent rock avalanches on older avalanches. It's actually a 300-500 ka edifice falling apart and with a sulfur-rich hydrothermal system.

Considering all the geological research done in Colorado, why hasn't anyone done isotopic dating of the supposed Quaternary volcanics near Dotsero Crater in over 50 years? The one Holocene eruption is based on one 14C date (4,150 BP) from a 1962 MS thesis. Never confirmed by later work. Venting...

The editor part of me cringed when I read that the study had leaked out from below the lithosphere.

Definitely a common issue. Difficult to resolve when more recent research is not available. About 400 volcanoes thought to be Holocene don't have documented eruptions.

Flores Island, Indonesia, this time. Though I am skeptical of a few in Alaska.

I love solving volcano mysteries. Latest case resulted in 3 eruptions from the 1880s reclassified as geo/hydrothermal, one from 2003 discredited due to bad aviation observations (wrong volcano). Finally, no Holocene eruption evidence, so volcano age status changed. ~signed, a US government scientist

I think leaving remote cabins unlocked is fairly common. People will break in anyway if they are determined. I was canoe guiding in the northern Ontario/Manitoba area, soon after ice-out, when a few of the crew became dangerously hypothermic. Open fly-in fishing cabin was a savior. Left $$ thanks.

Very little research in the area until some nice 2018 papers. Radiometric dating puts the "bombs" source cones/lava flows at over 80,000 years old, and youngest lavas in the overall at ~50,000. Boom! One less volcano on the Holocene list. 3/3

This was 1961, in a hard to find source. Same guy as a co-author on another paper in 1964 outright stated the last eruption was 1,500 years ago. Then it was repeated by others. Small rounded basalt pieces of uncertain source in a sediment layer suddenly became a Holocene eruption. 2/

Solved another eruption mystery, untangling some geological "telephone". It started with a volcanic field paper published as an appendix in govt report about bauxite resources. Volcanic "bombs" ~2 inches long were in a coastal deposit. Shells in layers above and below gave a 500 year window. 1/

Writers trying to prove their mettle shouldn't meddle with words they don't know 100%. Especially if their editor is equally clueless.
