Galtür: la tormenta perfecta

On February 23, 1999, a catastrophic avalanche struck the village of Galtur, killing 31 people. This event was caused by a combination of weather conditions, including a mild January that created a weak snow crust, and heavy snowfalls influenced by Atlantic and Arctic air masses. The avalanche doubled in volume as it descended, carrying 300,000 tons of snow at 300 km/h. This rare event highlights the powerful impact of atmospheric conditions on natural disasters.
