Eruptive activity at Mexico's Volcan de Colima in 2014 began with continued Vulcanian explosions that had started in January 2013 after 18 months of calm. Rockfall frequency was constant until early March, declined steadily through June 2014, increased again between July and September, and then tapered off once again through the end of the year. Explosion frequency also declined in March to a very low level by September, although the largest explosions (and pyroclastic flows they generated) occurred in the last quarter of 2014. Thirteen major lahars were recorded from two monitoring stations during the June through September rainy season; no damage was reported from these events. Three lava flows generating significant thermal anomalies formed on the WNW and SW flanks in September and November. By the end of 2014, the dome created in early 2013 had been destroyed by numerous explosive events. Information for this report comes primarily from geoscientists at the Colima Volcano Observatory and the Faculty of Science of Colima University, and also from the Washington Volcanic Advisory Center (VAAC), and the University of Hawaii MODVOLC thermal alert system.
