As a result, several communities were partially buried, causing fatalities and significant damage. An eruption and dome collapse occurred near the summit on 4 December 2021, which produced a notable ash plume and pyroclastic flows, the latter of which generated major lahars (BGVN 47:01). The current eruption has been ongoing since April 2014 and has more recently consisted of explosions, ash plumes, lava flows, pyroclastic flows, lahars, and dome collapse. Eruptions have been characterized by Vulcanian and Strombolian explosions, lava flows, pyroclastic flows, lava domes, and lahars. Hundreds of eruptive events occurred during the 19th and 20th centuries, including nearly continuous activity since 1967.
