There has been a collapse — call emergency services!
'Crollo' = KROL-loh. Double l. From 'crollare' (to collapse). 'Soccorsi' = sok-KOR-see (plural of soccorso).
Reporting a building collapse, structural failure or earthquake aftermath to emergency services.
'C'è stato un crollo' uses the passato prossimo of 'esserci' (there has been). 'Crollo' (collapse) is the technical term for any structural failure. Italy is one of Europe's most seismically active countries — the INGV (National Institute of Geophysics and Volcanology) monitors seismic activity. After an earthquake, Italian civil protection (Protezione Civile) coordinates emergency response.
L'edificio si sta sgretolando — evacuate!
The building is crumbling — evacuate!
'Sgretolarsi' = to crumble/fall apart gradually.
Ci sono persone sotto le macerie.
There are people under the rubble.
Critical information for rescue services — help them prioritise.
Ho sentito un'esplosione e poi il crollo.

Important detail for emergency responders — may indicate gas explosion.
Italy's Dipartimento della Protezione Civile coordinates national responses to natural disasters. Major recent collapses include L'Aquila (2009, 308 deaths) and Amatrice (2016, 299 deaths). INGV issues real-time seismic alerts and Italy has a nationwide earthquake early-warning research programme. The Protezione Civile app provides real-time alerts.
