The Hunga Tonga treaty

Did you know that there is an international treaty on eruptions? In truth, there isn’t. But there is a treaty on nuclear explosions, and there are similarities between explosive volcanic eruptions and nuclear explosions. Banning eruptions would go a bit above the United Nations powers. Could a volcanic eruption appear as a nuclear test? There…

Santa Maria: volcano in denial

Before climate change denial, there was volcano denial. This is the story about a forbidden eruption, the one that was suppressed and deleted from history. It is the one that got away. Blame Iceland. This post had been up for barely one day when events in Iceland rapidly moved towards another, potentially very damaging, Reykjanes…

Tambora: making history

In between Lombok (the location of infamous Rinjani) and Flores (with the magic lakes of Kelimutu) is the island of Sumbawa. It lies in the heart of the most volcanic region of the most volcanic nation on Earth. The two largest eruptions of the last 1500 years both came from this region. Lombok has never…

The mystery eruption of 1 Rabbit

Volcanoes can erupt invisibly. A sudden, swift explosion in an isolated location may be unobserved and still have worldwide impacts. The source of the large eruption of 1809 remains unknown. We still don’t know the culprits of the volcanic climate catastrophe of 536 and 540. The link between the year without summer of 1816 and…

What Would Make a VSI 12?

Guest post by Tallis My father and I disagree on a lot of things from religion, politics, career, and more; One of the things we disagree on is the title of worst geological disaster. I believe that title goes to volcanoes while my father believes it goes to earthquakes. This is actually a fun point…

The VEI-5 millennium eruption of Hunga Tonga

It seemed to come out of nowhere. In the midst of a quiet interlude, after the hugely damaging La Palma had ended, when the hugely touristic eruption at Fagradalsfjall failed to re-appear, and the hugely underwatched eruption at Kilauea continued to be underwatched, whilst we were waiting for Reykjanes (which some had predicted to recur…

The Terraces of Tarawera

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…

Future calderas

Volcanoes erupt all the time. It may seem a quiet time to us but that is because most eruptions are small and low impact, and stay below the radar. An excellent daily overview can be found on http://lechaudrondevulcain.com/blog-spotlight-two-column/ As I write this, it lists on-going eruptions at Sinabung, Etna, Stromboli, and Sabancaya. Volcanodiscovery also lists…
