Harrat Lunayyir

Lunayyir, Harrat

Campo volcánico · Saudi Arabia · 1370 m

Lava flows radiate down desert valleys away from the center of Harrat Lunayyir, a basaltic volcanic field in NW Saudi Arabia, east of the Red Sea port of Umm Lajj. Harrat Lunayyir contains about 50 volcanic cones that were constructed along a N-S axis. Harrat Lunayyir is one of the smallest of the Holocene lava fields of Saudi Arabia, but individual flow lobes extend up to about 30 km from the center of the Harrat. One of the cones may have erupted around the 10th century CE or earlier.

Resumen geológico

Harrat Lunayyir is a basaltic volcanic field in NW Saudi Arabia, east of the Red Sea port of Umm Lajj. It contains about 50 volcanic cones that were constructed over Precambrian crystalline rocks along a N-S axis. Harrat Lunayyir is one of the smallest of the Holocene lava fields of Saudi Arabia, but individual flow lobes radiate long distances from the center of the Harrat, and flows reached the Red Sea in two places. Lava flows are basaltic to basanitic in composition, and the Holocene flows are alkali olivine basalts. One of the cones may have erupted around the 10th century CE or earlier. A seismic swarm in May 2009 was interpreted to be consistent with intrusion of an 8-km-long dike to shallow crustal levels.

Resumen de Wikipedia

Resumen en inglés

Ḥarrat Lunayyir is a lava field in northwestern Saudi Arabia. In 2009 there were swarms of small earthquakes in the area; 2289 people were evacuated from the area. Fissures opened on the surface, and the area might now be considered volcanically active.
