Video of a big lahar coming off Mt Semeru, Indonesia today, just a couple of days after its massive eruption. You can see it flowing down a channel, exactly what these paths are designed for to protect villages. The lahar travelled 13 kilometres from the summit of Java's highest mountain A lahar is a fast-moving mix of ash, rock, and water. Indonesians call it “banjir lahar dingin,” often translated as “cold lava flood,” even though it’s not lava, just volcanic debris in motion. It was caused by moderate-to-high rainfall around Mount Semeru.

🇮🇩 Massive lahar coming off Mt. Semeru, Indonesia today... A lahar is a fast‑moving debris‑ and water‑filled flow (volcanic material) that travels down the slopes of a volcano - essentially a “volcanic mudflow.” The timing can vary widely - from days to weeks, even months or years after the eruption - depending on how quickly rain or other water sources remobilize the loose material.

🇮🇩 Another lahar today from Mount Semeru. As you can see in the video, it can look like cement or carry huge boulders. It also kicks up ash which can cause breathing difficulties and poor visibility.

Mt. Semeru in Indonesia HAS NOT erupted again. What you're seeing is another lahar. A lahar is a volcanic mudflow that can occur when rainwater mixes with deposits of hot volcanic material from a previous eruption, in this case, the major eruption on November 19th. Because these deposits are still hot, the contact with rainwater can sometimes trigger secondary explosions. In short, there is no new eruption, just a dangerous lahar caused by rain interacting with still-hot volcanic deposits.

You don't believe in Mudfloods? Houses buried in Indonesia. With just one event, the material expelled by Mount Semeru Volcano made a lot disappear, so, imagine a cataclysm across the entire world.
