Courtesy of SkyAlert (2 March 2016).Īsh plume heights during March 2016 were slightly lower than during February (4.0-6.1 km altitude). The lava dome at Colima photographed on 29 February 2016 was noticeably larger than when first photographed ten days earlier. They generally drifted a few tens of kilometers before dissipating, but a few were still visible as far as 200 km from the summit.įigure 122. The ash plumes rose to altitudes of 4.3-6.7 km and most commonly drifted N or E. The Washington VAAC issued multiple advisories nearly every day during the month with information based on satellite imagery, wind data, webcam images, and notices from the México City Meteorological Watch Office (MWO). ![]() Ash emissions continued at Colima at a very high rate of multiple daily events, similar to December 2015 (figure 120). Incandescent activity during explosions in January 2016 sent glowing blocks down the flanks of Colima along with spectacular lightning in the ash plumes (figure 119). ![]() Decreasing seismicity and minor landslides were reported through June 2017 with no further eruptive activity. Activity decreased during the second half of February the last ash-bearing explosion was reported on 7 March 2017. Strong ash-bearing explosions during December 2016-January 2017 sent plumes to heights of 4-6 km above the crater. A second lava flow appeared in mid-November, and advanced 1.7 km by early December. The lava flow continued to grow, reaching over 2 km in length by the end of October. On 30 September, the lava dome overflowed the crater rim, and sent a slow-moving lava flow and incandescent material down the SW flank. Activity decreased during May-September, although multiple explosions with ash plumes still took place most weeks during the period. Most of the information for this report was gathered from the Unidad Estatal de Protección Civil de Colima (UEPCC), the Centro Universitario de Estudios e Investigaciones de Vulcanologia, Universidad de Colima (CUEIV-UdC), and the Washington Volcanic Ash Advisory Center (VAAC).Ĭolima was very active from January through April 2016 with hundreds of ash emissions, and a slow-growing lava dome that was first observed on 19 February. ![]() This report covers the activity through June 2017. The eruption continued throughout 2016 until the last ash-bearing explosion was reported on 7 March 2017. Extensive activity in 2015 included near-constant ash plumes with extensive ashfall, lava flows, and pyroclastic flows (BGVN 41:01). The latest eruptive episode began in January 2013. 3850 m All times are local (unless otherwise noted)įrequent historical eruptions at México's Volcán de Colima (Volcán Fuego) date back to the 16th century and include vulcanian and phreatic explosions, lava flows, large debris avalanches, and pyroclastic flows.
