An avalanche,Philippines Archives likely triggered by an earthquake, has buried a hotel in the Italian region of Abruzzo, leaving at least 30 people missing.

Rescuers have worked relentlessly to reach the four-star Hotel Rigopiano, close to Gran Sasso mountain.

A series of earthquakes hit the region Wednesday, including one with a 5.7 magnitude.

Local residents alerted emergency services after the hotel's roof partly collapsed. But rescue efforts were hindered by a snowstorm which blocked access to the hotel.

Pictures showed rescuers shovelling their way through a wall of snow, and at least one man being led through the cleared path.

Other images showed rescuers entering the hotel, with piles of snow and rubble cascading down the stairs into the entryway.

On Tuesday, before the earthquakes, the hotel had posted photos of the snowfall on its Facebook page. "It's a dream Tuesday. The snow gives us spectacular scenes," it said.
