Update 8 Nov 2024 As commented below, NASA has produced a new image and image slider showing the ash cloud from the eruption: https://earthobservatory.nasa.gov/images/153549/mount-lewotobi-laki-laki-spews-ash The lava flow running east is the one produced in January-March. The blacker ash covers around 20km>sup>2 in this image. That suggests a volume of 0.01 to 0.001 km3: no more…
Indonesia is a country of volcanoes. An impressive amount of subduction-related volcanoes. The country features four different volcanic arcs, chains of volcanoes above subducting oceanic plates. The most important one is the Sunda Arc, home to way too many famous volcanoes like Toba, Krakatau, Galunggung, Merapi, Semeru, Bromo, Kawah Ijen, Batur, Agung, Rinjani, or Tambora.…
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…
As has been noted here, little is known about people living near volcanoes which had a VEI-7 eruption. But we do know something about Tambora. The slope of Tambora, on the Sangar peninsula of the island of Sumbawa, was home to the Kingdom of Tambora. The kingdom had been mainly located some distance from the…
Carl This post was written by Carl in 2012, during an eruption of Soputan. Some updates have been done and some hindsight has been added. Some volcanoes just can’t catch a break. Imagine for a little while that you are a bona fidé supervolcano. You are the largest of your type on the planet, you…
Morn came and went – and came, and brought no day Lord Byron, Darkness, 1816 The world has changed. It is not something we normally notice – change is slow and memory surprisingly selective. Nothing has altered but everything’s changed, as the song says, paraphrasing Jean-Paul Sartre. We have little idea of how our parents…
In Part 1 and Part II we went over the current state of Krakatau and its history over the 300 years before the Big One. Now it is time to find out what caused the Big Bang, whether it is a recurrent offence, and to try our hand at the big question: why is such…
In part I, we discussed the geology and current state of Krakatau. Now it is time to look at events before the Big Eruption. Was it hiding in the shadows, or did it make its intentions clear to all? History For centuries before its destruction, Krakatau was a familiar landmark. At least some of the…
Links to Part II and Part III. Other Krakatau posts: Krakatoa: a blast from the past Krakatoa skies: when the Sun turned blue The rise and fall of Anak Krakatau All eruptions have history. Volcanoes may sometimes appear to erupt out of the blue; the mountain may not even have been recognized as a volcano,…
Let’s start with a question. Which country do you think has the most frequent volcanic eruptions? Before you read on (or peek below for the answer), take a minute to think about it. You can probably guess that Australia is not a front runner. In fact, only two or three countries readily come to mind.…
