Siayan is one of the Batanes Islands. Also known as Ditarem Island in the native language,[1] the island is about 1/2 mile to 3/4 miles in diameter and lies about 5 miles (8 km) north-northeastward of Itbayat Island. The closest island is Mavulis Island which is about 1Template:Frac miles north-northeastward of Siayan. There are several detached rocks off Siayan's northeast side, rendering the channel between it and Mabudis unsafe for larger vessels.[2]

Siayan has an elevation of 538 ft (164 m) and is listed as an inactive volcano[3] by the Philippine Institute of Volcanology and Seismology.
