This 7x-speed footage captures a massive pyroclastic flow racing down Indonesia’s Mount Semeru as the volcano unleashed a powerful eruption. | AccuWeather

🌋 You cannot outrun this. In Feb 2014, a massive pyroclastic flow thundered down Sinabung, Indonesia a ground-hugging avalanche of superheated ash and gas. Over 500°C. Speeds topping 100 km/h. This isn’t lava. It’s the deadliest force a volcano can unleash. No second chances.

PYROCLASTIC FLOW A pyroclastic flow is a fast-moving current of extremely hot gas, volcanic ash, and rock fragments that rushes down the slopes of a volcano during explosive eruptions. These flows can reach speeds of over 320 km/h and temperatures exceeding 1,000 °C, making them one of the most dangerous volcanic hazards. Unlike lava flows, pyroclastic flows can travel great distances, destroy everything in their path, and cause widespread devastation due to their speed, heat, and suffocating as

Pyroclastic flow observed at Semeru Volcano This sped-up (x7) footage shows a pyroclastic flow descending the slopes of Semeru. These flows consist of hot ash, gas, and fragmented rock moving rapidly under gravity. Semeru remains one of Indonesia’s most active volcanoes and is continuously monitored.
