While we are waiting for more information (and daylight) on the large Pacific eruption, here is a repost. It complements the previous post on igneousity (for which surely the ig-nobel prize was invented?). Enjoy. What’s in a name. Would lava by any other name smell as sweet? Perhaps that is not the right question: lava…
In the last decade, science has been under increasing attacks and have lost in status among the general population. Where famous scientists a century ago could rake in some serious dosh by going on lecture tours explaining their findings, today’s scientists are increasingly unknown and scorned by the general population. Instead, we see the rise…
Rock, rock, rock There are only three types of rocks. This may be surprising, seeing no two rocks are the same and geologists use a never-ending series of names for these rocks, from abelsonite to zykaite. Names are what makes geology so hard. Henrik has written about gem stones, in a highly recommended post. But…
From all of Us to all of You: A happy Christmas and a Volcanic New Year! Victoria Island Our story begins and ends in the far north of Canada. The sea between northwestern Canada and northwestern Greenland is filled by a series of ancient islands. In winter the sea is deeply frozen, and the islands…
Here is the third part of my Kilauea series that was promised, a bit more delayed than I would have wished though. Many things have happened at Kilauea since the previous part. A sill intrusion took place in the Upper Southwest Rift in August, then on September 29, about a month after the sill, lava…
It began on 24 May, 2015. Unannounced, unnoticed and unforeseen, in the middle of the night Wolf Volcano suddenly erupted. For all its fame, volcanoes on the Galapagos are not well monitored. After all, this is far from anywhere, so remote that not even the Polynesians found the islands. Its fame comes from its very…
First of all, I should clearly state that there are no current signs that an eruption at Katla is about to happen in the near future. Instead, the reason is that I was asked by one of our readers, Patricio Oliver, what would happen if the volcano erupted, especially for the inhabited areas. This is…
This post is about the Tarawera Kaharoa eruption, and shows that it happened in June 1306. But it is a long story, connecting places as far apart as Taiwan, Ecuador and the Antarctic Peninsula. Enjoy! Large volcanic eruptions throw out their ash and gas into the atmosphere and forget about the mess. They are heavy…
It was a quintessential English village, with simple houses along streets and fenced cottage gardens of precisely 100 m2 each. This is what the heart of England, the Cotswolds, looked like. Perhaps 85% of the population was local; the others were distant immigrants. The people were farmers and workers in the local flour mill. But…
“When in doubt, data shall provide the answer!” In the beginning A decade ago to the day, the first article was published here at Volcanocafé. It was not one of the memorable ones that I remember without checking, but from humble starts came many memorable articles over the years. Starting Volcanocafé was quite unexpected…
