🏝️ Anydros

Anydros is an uninhabited Greek islet in the municipality of Santorini, which is a group of islands in the Cyclades. It is north of the island Anafi, and southwest of Amorgos. It is sometimes called Greek: Αμοργοπούλα, romanized: Amorgopoúla. The island hosts a seismometer, part of the Greek national network, installed in 2025. An earthquake fault located near Anydros was the source of the 1956 Amorgos earthquake that registered 7.6 on the Richter scale and caused widespread damage on Amorgos and the island of Santorini, where dozens died. A second 7.5 quake and a 30-meter tsunami followed.
