Two forces conspired to create the disaster. Record snowfall had blanketed the Gran Sasso d'Italia massif in the days preceding 18 January, loading the slopes above Rigopiano with enormous volumes of snow. Then, on the morning of the avalanche, a series of earthquakes shook the region -- tremors from the same seismic sequence that had devastated Amatrice five months earlier. Whether the earthquakes directly triggered the avalanche or merely destabilized already-precarious snowpack remains debated, but the timing was unmistakable. The 28 guests and 12 employees at the Hotel Rigopiano, a mountain retreat in the municipality of Farindola in Abruzzo, found themselves caught between geological forces converging from above and below.

The avalanche largely destroyed the hotel, burying it under at least four meters of snow. Two people survived because they happened to be standing outside when the wall of snow hit. Inside, nine others clung to life in air pockets created by loft spaces that had not fully collapsed. These survivors were located around noon on 20 January -- more than 30 hours after the avalanche struck -- and the last were pulled free after 58 hours, having sustained themselves by eating frozen snow. Five adults and four children emerged alive from the wreckage. Ten of the eleven survivors suffered injuries related to hypothermia; the eleventh required surgery for a compression injury to his arm. On 23 January, rescuers found three puppies alive beneath the debris, briefly raising hopes that more human survivors might be found. None were.

Criticism mounted swiftly over the emergency response. A survivor who remained outside the buried hotel called for help immediately, but alleged that authorities initially refused to believe an avalanche had actually struck. Quintino Marcella, a restaurant owner in Silvi who received the survivor's desperate call, said he contacted authorities repeatedly and was not taken seriously. The rescue workers' base camp was established roughly 10 kilometers from the hotel. Emergency services, civil protection teams, alpine rescue units, and volunteers -- including asylum seekers -- eventually converged on the site, using drones, body-heat sensors, and phone signal tracking to locate victims. Autopsies later revealed that nearly all 29 victims had died instantly from the impact itself, not from hypothermia in the days of waiting.

Prosecutors launched both a manslaughter investigation into the delayed emergency response and a separate inquiry into whether the hotel had been built on the path of previous avalanches. A trial beginning in 2019 concluded in February 2023 with five convictions. The mayor of Farindola, Ilario Lacchetta, received the longest sentence -- two years and eight months -- for failing to order the hotel's evacuation, though he was acquitted on 25 other charges. The hotel's former manager and an engineer who had approved its balconies and canopies were also found guilty. The former prefect of Pescara and the former provincial president were acquitted. Victims' relatives, who had waited six years for justice, protested the verdicts in the courtroom.

On 18 January 2018, exactly one year after the disaster, a day of remembrance was held at the ruins of the Hotel Rigopiano. Victims' relatives, local residents, and representatives of emergency services gathered to read prayers and poems and lay flowers. Photos of the 29 people who died were displayed alongside the words "Never Again" -- a phrase that carried both grief and accusation. The disaster was the deadliest avalanche in Italy since the White Friday avalanches of 1916 and the worst in all of Europe since the 1999 Galtur avalanche in Austria. It left behind questions that the trial only partially answered: how a hotel in a known avalanche corridor operated without adequate warning systems, and how an entire afternoon of earthquakes and panicked guests was not enough to trigger an evacuation.
