About Haylan, Jabal
Haylan, Jabal is a volcanic field rising to 1,550 meters (5,086 feet) in Yemen's Arabia-Central Asia Volcanic Regions. Its last known eruption dates to 1200 BCE, in prehistoric times. The volcano has produced 1 recorded eruption.
Geography & Climate
Haylan, Jabal is located in Yemen, within the Southwest Arabia Volcanic Province of the broader Arabia-Central Asia Volcanic Regions. Situated at 15.40° N, 45.10° E in the Northern Hemisphere, the volcano lies within a tropical climate zone. With a summit elevation of 1,550 meters above sea level, Haylan, Jabal is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Haylan, Jabal is an intraplate volcano, meaning it formed away from any plate boundary. These volcanoes are often powered by hotspots — plumes of abnormally hot mantle material rising from deep within the Earth. Hotspot volcanoes like Haylan, Jabal tend to produce effusive eruptions with lava flows that can be relatively predictable, giving nearby communities in Yemen more time to prepare. However, they can also produce explosive phases, particularly when magma interacts with groundwater. The dominant rock type is basalt / picro-basalt, 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.
Eruption History Summary
Haylan, Jabal has 1 recorded eruption in the geological database, spanning from 1200 BCE to 1200 BCE.
GVP Reference Summary
The Jabal Haylan area contains a 75-km-long chain of tuff cones and associated olivine basaltic lava flows in eastern Yemen. The chain crosses a NW-SE-trending fault extending between the highlands and desert lowlands to the east. One of the lava flows covers alluvial terraces that accumulated behind man-made dams from about 800-1200 BCE (Catalog of Active Volcanoes of the World).
