How were people killed in the mountt pelee eruption?

During the Mount Pelée eruption in 1902, the city of Saint-Pierre, located on the island of Martinique, was devastated by a series of pyroclastic flows and volcanic ash clouds. These fast-moving currents of hot gas and volcanic matter surged down the mountain, reaching speeds of up to 100 km/h (62 mph) and temperatures exceeding 800°C (1,472°F). The combination of intense heat and asphyxiating gases resulted in the immediate deaths of approximately 30,000 residents, making it one of the deadliest volcanic eruptions in history. Many victims were caught unprepared, as the eruption followed a period of relative calm, leading to a tragic underestimation of the volcano's threat.
