  "account": "ANSA reported on 14 Jul 2025 that Ferrovie dello Stato's infrastructure company Rete Ferroviaria Italiana had activated Italy's first seismic early-warning system. It is on the Rome-Naples high-speed line. It was developed with the Physics Department of the University of Naples Federico II. Technical support came from the Railway Technical Research Institute of the Japanese railways. A network of latest-generation sensors detects the earliest seismic waves. Within seconds it automatically activates safety protocols to slow or stop trains. euronews (15 Jul 2025) added that the system comprises about 20 seismic stations along 200 km, on the surface and in deep boreholes. They are linked by an SDH fiber network. An advanced software intelligence instantly analyzes the data and assesses the quake's danger, per euronews. The system had been operational since 3 May 2025. In the following weeks it was tested by a magnitude 4.4 earthquake. During it, trains on the Rome-Naples line were stopped preventively. Neither article gives the date of that earthquake. ANSA does not mention artificial intelligence. The OECD AI Incidents Monitor lists the system as AI-powered and a protective response.",

            "account": "ANSA reported on 14 Jul 2025 that Ferrovie dello Stato's infrastructure company Rete Ferroviaria Italiana had activated Italy's first seismic early-warning system. It is on the Rome-Naples high-speed line. It was developed with the Physics Department of the University of Naples Federico II. Technical support came from the Railway Technical Research Institute of the Japanese railways. A network of latest-generation sensors detects the earliest seismic waves. Within seconds it automatically activates safety protocols to slow or stop trains. euronews (15 Jul 2025) added that the system comprises about 20 seismic stations along 200 km, on the surface and in deep boreholes. They are linked by an SDH fiber network. An advanced software intelligence instantly analyzes the data and assesses the quake's danger, per euronews. The system had been operational since 3 May 2025. In the following weeks it was tested by a magnitude 4.4 earthquake. During it, trains on the Rome-Naples line were stopped preventively. Neither article gives the date of that earthquake. ANSA does not mention artificial intelligence. The OECD AI Incidents Monitor lists the system as AI-powered and a protective response.",
