Anafi in the context of "Folegandros"

Anydros (Greek: Άνυδρος) 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.

There were hundreds of minor earthquakes of up to magnitude 5 in an area around Anydros at the beginning of February 2025, causing concern in Santorini and causing more than half the population to leave the island. The seismic activity was attributed to tectonic plate movements rather than volcanism, and it was thought that it could last weeks.

Thira (Greek: Περιφερειακή ενότητα Θήρας) is one of the regional units of Greece. It is part of the region of South Aegean. The regional unit covers the islands of Thira (Santorini), Anafi, Folegandros, Ios, Sikinos and several smaller islands in the Aegean Sea.

Internal exile was used to punish political dissidents by various Greek governments, including the Pangalos Regime (1925–1926) and the Metaxas 4th of August Regime (1936–1941), the government during the Greek Civil War (1946–1949), and the Greek junta (1967–1974). Those targeted were typically sent to smaller, often uninhabited Greek islands. Many of these island sites operated only as prison islands, among the most notorious including Makronisos, Gyaros, and Agios Efstratios, where barracks and facilities for housing prisoners served as concentration camps. Over 100 locations across Greece were used for political exile at various times in the 20th century.
