One of the most active volcanos in Iceland erupted in January after 10 years of repose. Hekla, located in southern Iceland (63.98°N, 19.70°W), erupted on January 17, according to reports from the Smithsonian Institution's Global Volcanism Network. The following account is from the GVN Bulletin, December 1990. (Local time = UT)
On January 17 an eruption ejected tephra columns and fed numerous fluid lava flows from fissure vents. Local farmers noticed strong sulfurous smells around 1200–1300, 4–5 hours before the eruption began. Instruments, however, gave less than 40 minutes warning of the eruption.
