Overview

The 2 x 4 km island of Serua is the emergent summit of a volcano rising 3,600 m above the Banda Sea floor. A truncated central cone surrounded by an old crater wall is capped by the Gunung Wuarlapna lava dome. This andesitic volcano, also known as Legatala, lies near the center of the Banda arc and has had many eruptions recorded since the 17th century.

Volcanic Hazards & Risk Assessment

Primary Hazards

  • Pyroclastic flows
  • Lava flows
  • Volcanic bombs and ballistics

Regional Volcanic Activity
The Sunda-Banda 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, 2 x 4 km island of Serua, seen here from the north, is elongated in a NE-SW direction. An unvegetated lava dome forms the summit of the volcano, which rises 3600 m above the Banda Sea floor. The 641-m-high truncated central cone is surrounded by an old somma wall. Serua, also known as Legatala, is one of the most active of the Banda Sea volcanoes, with many eruptions recorded since the 17th century.
