Mount Unzen’s Background

Mount Unzen lies in Kyushu, a small island in Japan. It is a composite volcano, also known as a stratovolcano. It is a cluster of overlapping volcanoes instead one by itself. There have been many disastrous eruptions from this volcano, it is currently active. Its most recent eruption was in 1991. Its explosions are usually explosive. Unzen’s full name is Unzen-dake. This volcano got its name from all the hot springs around it. “Unzen” means hot springs and “–dake” means peak. Basically, Unzen-dake means hot spring mountain. This volcano is not blamed for erupting. After all, it is on the Ring of Fire.

1792…What Happened?

There was a rumbling sound in the distance. The people of Kyushu trembled in fear. Was it an earthquake? What was it? BOOOOM!! Mount Unzen erupted violently. The worst was not over. Suddenly, an earthquake shook Kyushu. The earthquake has caused an avalanche from Mount Mayuyama! It was collapsing on people! Then there was a tsunami! Kyushu was at its worst day. The whole thing was like a Rube Goldberg to destroy Kyushu. The volcanic eruption triggers an earthquake, which caused a lava dome collapse, which made a tsunami. In total, there were more than 14,000 deaths!

What Came Out?

This deadly eruption bursted with pyroclastic material. It was strong enough to create an earthquake so the type of pyroclastic material must’ve been large. According to a website, the volcano was shooting out volcanic bombs and volcanic blocks. There was (but not a lot of) volcanic ash.

Formation of Mount Unzen

Mount Unzen is super dangerous. How did it even form? This is a hard question sometimes because volcanoes form and process underground, making it difficult to predict and understand. According to Universe Today, “It is believed that this volcano originated as a result of crustal faulting which eventually formed a graben, or a depressed stretch of land typically due to tensional forces and crustal faulting.”
