Harras of Dhamar

Dhamar, Harras of

화산대지 · Yemen · 3500m

The Harras of Dhamar volcanic field is shown in this December 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 51 km across). The field contains many scoria cones and associated lava flows, with some older obsidian lava flows. Many of the cones have amphitheater-shaped craters due to flank collapse or rafting.

지질학적 요약

The lava fields surrounding the town of Dhamar are part of a volcanic field extending 80 km E that includes several stratovolcanoes and many youthful volcanic cones. Basaltic lava flows overlie older rhyolitic flows. Residents near Dhamar "spoke of a volcanic eruption that must have taken place in 1937 near the town" (von Wissmann, 1942; Rathjens and von Wissmann, 1942; cited in Neumann van Padang, 1963); this supposed activity has not been confirmed, located, or described by later work.
