Overview

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.

Volcanic Hazards & Risk Assessment

Primary Hazards

  • Pyroclastic flows

Regional Volcanic Activity
The Western Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

The small island of Mare (left-center) lies between Tidore (top-center) and Moti (bottom-center) volcanoes in this NASA Landsat image (with north to the top). Mare is one of a chain of volcanic islands off the western coast of Halmahera Island (right). The 2 x 3 km island is elongated in a NE-SW direction, and a large breached crater is located off the SW tip of the island.
