In Italy, a powerful 6.6-magnitude earthquake toppled centuries-old churches and crumbled Roman walls but did not cause any deaths. It was Italy’s most powerful quake since 1980. A series of foreshocks earlier in the week forced the evacuation of thousands of at-risk residents, likely saving many lives. Thousands remain homeless, and a leading seismologist warned that more earthquakes could continue along central Italy’s fault system for weeks to come.
