Japan’s largest volcano lies hidden. It can be found, if you know where to look, by starting from the southern island of Kyushu. Find the active volcano Sakurajima. (We will come back to it later. But this is not that volcano.) Sakurajima lies in-between two bays, the twin calderas Aira and Ata: follow the bay…
It began 2 April 1991, 35 years ago this month. Hidden targets There are many volcanoes in the world. At any one time, perhaps 20 volcanoes may be erupting. Over a full year, on average around 50 volcanoes erupt. Some of these may erupt several times – as Kilauea has done episodically in spectacular fashion,…
Wouldn’t it be nice to be able to forecast major eruptions? So far, the opportunity has been lacking. VEI-7 eruptions are rare: we have not seen one since Tambora in April 1815. To make a right forecast, the event needs to happen! Part of the forecast is recognising that the mountain is a volcano. Tambora…
1 million people visit Vesuvius each year. It is a big number which involves a lot of people struggling up the steep and dusty path to the rim. Rather more people visit the more accessible archaeological monument to Vesuvius that is Pompeii: counting those as well brings the total to 2.5 million. It makes it…
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…
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…

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…
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…
Think of one thing that has interested you for as long as you can remember, or at least for so long the level of factual knowledge you have of it is almost ridiculously vast. That one thing that always brightens up your day when you hear or read something about it, no matter how busy…
