How Greece Santorini's Cliff Towns Survived 20,000 Earthquakes on a Volcano

The Santorini earthquake swarm of 2025 shook the island more than 20,000 times in four weeks. Its towns sit on a volcano's rim, on cliffs up to 300 meters high. Every lifeline climbs that cliff or crosses the sea: the rockfall-prone road from Athinios port, the Fira cable car, desalinated water and a new undersea power cable. Then scientists tracked magma moving near the Kolumbo volcano. 0:00 20,000 Earthquakes in Four Weeks 0:35 Towns on the Rim of a Volcano 2:44 Pumice Cliffs and the 1956 Quake 5:17 Rockfalls, the Port and the Cable Car 7:48 Water, Power and the Sensors 10:47 February 2025: State of Emergency 12:46 What Was Moving Under the Sea 14:10 February 10: The Magnitude 5.3 Test 15:53 New Rules on the Cliff Edge Key facts: - Strongest quake: magnitude 5.3 (Feb 10, 2025) - More than 10,000 people left in days - Schools closed 4 weeks; reopened March 4, 2025 We break down the world's hardest engineering projects, step by step, with every number sourced.
