Taal eruption update

In my previous article I wrote that Taal most likely would not continue to erupt for a long period of time, based on the previous history of the volcano. Obviously Taal decided to go for something not recorded in the historic annals. It is therefore time to take a deeper look at what is going…

Taal Update – Ongoing Intrusion

Guest post from Héctor (DustDevil). There will be a further update either later today or tomorrow as events have changed since Héctor wrote this post. The Main Crater of Taal seems to have calmed down, doesn’t it? However fissures are breaking the ground apart, the river dries, Lake Taal falls and strong earthquakes keep coming.…

Taal in Eruption

This will probably become one of the most famous wedding pictures in history. I fear that this accidental picture will create a fashion and that people will try to recreate it at ever more dangerous volcanoes. In this case it was accidental, this wedding was most likely planned for weeks, if not months, prior to…

Ross at Ambrym

Re-posted, from January 24, 2014 Our dear Mike Ross is currently (that was written 5 years ago – editor) at the volcano on Ambrym Island in Vanuatu photographing a documentary. Apparently Ambrym means “Here are yams” in the local tongue. The volcano is a large shield volcano constructed by alternating layers of pyroclastic deposits and…

The Gentle Giant of Africa

Unless you are more interested in volcanoes than is technically healthy, it is likely that you have missed out a lot on the classic Monty Python skit ‘The twin peaks of Kilimanjaro’. Most people laugh at it since they believe that there is only one peak, but for us with an un-checked interest in volcanoes,…

The Woolly Mammoth-Sized Eruption Poll – One Year On

It’s been one year, yes one whole year of DNA damage and telomere shortening, since the last poll and we’re all still waiting to see who’s going to go first. We’ve seen activity increase in some areas and decline in others. Will that have swayed your opinion or will you stick to your previous vote…

Lava Lakes – The Great Equilibrium Machine

A while ago Jesper Sandberg asked a question about if Grimsvötn could sprout forth a lava lake. I somewhat sloppily answered that I did not think that it was possible. Jesper then asked why not, and I got somewhat flustered since I did not have a ready answer. I promised to come back with a…

Strong tremor signal detected at Grimsvötn

At 19.03 local time the automatic SIL-system in Iceland picked up a strong tremor signal. When this type of tremor signal is visible in Iceland it is normally associated with either a large jökulhlaup (rapid glacial melt outflow) that can become larger than the output of the Amazon River, or it is associated with an…

Holohraun Five Years Later

A guest post from Salting I visited Iceland many times in the past to meet friends and take a day off on my way between Europa and US. In summer 2011 I made an extra-long stop and visited a glacier to better understand the forces that shaped the coastline around my Swedish home island. Trekking…

Was Puyehue Cordón-Caulle really a VEI-5?

That the question even exist is a bit of an oddity in modern volcanology, after all we have known amply how to take ejecta-depth measurements to create Isopac-maps since 1956, more about that below. The reason that this question has prevailed is that there are anomalies in the numbers proven for the eruption, compared to…
