About Mare
Mare is a stratovolcano rising to 308 meters (1,011 feet) in Indonesia's Western Pacific Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Mare is located in Indonesia, within the Halmahera Volcanic Arc of the broader Western Pacific Volcanic Regions. Situated at 0.57° N, 127.40° E in the Northern Hemisphere, the volcano lies within a tropical climate zone. At just 308 meters above sea level, Mare is a relatively low-elevation volcanic feature. Despite its modest height, it remains an active geological formation with the same underlying magmatic processes as its taller counterparts. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Mare sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Indonesia near Mare, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is andesite / basaltic andesite, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
GVP Reference Summary
The small volcanic island of Mare, immediately south of Tidore, was mapped as Holocene in age by Apandi and Sudana (1980). The 2 x 3 km island, part of a chain of volcanic islands off the western coast of Halmahera Island, is elongated in a NE-SW direction. A large breached crater at the andesitic volcano is located off the SW tip of the island.

Frequently Asked Questions About Mare
Is Mare an active volcano?+
Mare is classified as active based on credible evidence of past eruptions. Although its last known eruption was in prehistoric times, volcanologists consider it capable of erupting again.
How high is Mare?+
Mare has a summit elevation of 308 meters (1,011 feet) above sea level. At 308 meters, it is a relatively low-elevation volcano.
What type of volcano is Mare?+
Mare is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Mare located?+
Mare is located in Indonesia, in the Western Pacific Volcanic Regions. More specifically, it lies within the Halmahera Volcanic Arc. Its exact coordinates are 0.570° latitude, 127.400° longitude.
Is it safe to visit Mare?+
Mare can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. Indonesia may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
