Weh Island
Sumatra Region
Weh Island, also known locally as Pulau Weh or Sabang, is a small active volcanic island located northwest of Sumatra in Indonesia. Covering approximately 122 square kilometers, the island was once connected to the Sumatran mainland but became separated due to a volcanic eruption in the Pleistocene era. It is characterized by mountainous terrain with its highest peak, Cot Kulam, reaching 617 meters. The island's ecosystem is notable for its rich marine biodiversity, including coral reefs that support a large variety of fish species and rare fauna such as the threatened toad species Duttaphrynus valhallae. The Indonesian government has designated 60 square kilometers of the island and surrounding sea as a wildlife protection area. Weh Island is also known for underwater fumaroles near Sabang city and at Gapang Beach, which are popular diving sites. The economy has diversified from traditional agriculture and fishing to include construction, trade, and services, with Sabang city serving as a free trade zone and important port. The island is accessible by ferry from Banda Aceh and served by Maimun Saleh Airport, enhancing its connectivity for tourism and commerce.

History
Weh Island was originally part of the Sumatran mainland but became an island following a volcanic eruption in the Pleistocene era, which led to the partial collapse of its volcanic peak.
Historically, Sabang city developed as a strategic port in the late 19th century, initially serving as a coal station for the Dutch Royal Navy and later expanding to handle commercial shipping.
In 2000, Sabang was declared a Free Trade Zone and Free Port by the Indonesian government to leverage its position near the Malacca Strait, a major international shipping route.
The island was affected by the 2004 Andaman Sea earthquake and tsunami, though the impact was relatively limited compared to other areas.
