piroklasztáráradások
Piroklasztáráradások, also known as pyroclastic flows, are fast-moving currents of hot gas and volcanic debris that are extremely dangerous. They are formed during explosive volcanic eruptions when the volcano expels a mixture of hot ash, gas, and rock fragments. These flows are a combination of solid particles and gases, and they travel down the slopes of a volcano at very high speeds, often exceeding 100 kilometers per hour. The temperature within a pyroclastic flow can range from 200 to 700 degrees Celsius, making anything caught in their path susceptible to ignition and destruction.
The composition and behavior of pyroclastic flows can vary. They can be dense and ground-hugging, or more
