Step 2: because it happened in complete silence, the sleeping inhabitants did not realize what had happened. The source says the village was moved and buried “without the least noise”[2][3].

The source draws a sharp line between avalanche types: drift avalanches are loose snow with violent air compression, while sliding avalanches are a frozen sheet thawed from below and sliding as one mass. Ice avalanches are glacier fragments breaking apart[4][5][6][7][8].
