Volcán de Colima is one of the most active volcanoes in Mexico. Because of its eruptive style, which reaches from lava extrusion (mainly as a dome within the crater) interspersed by Vulcanian explosions to dome destroying Plinian eruptions accompanied by pyroclastic flows, it possesses a major thread to local population. Up to now, reliable forecasting of possibly hazardous events is impossible because we still lack some pieces of the puzzle. To better understand this volcano's activity, we set up a Doppler radar monitoring station: A ground based remote sensing tool to measure the amount and velocity of volcanic particles. The Doppler radar was continuously observing the crater for more than one year, day and night. Using statistical analysis of time intervals between eruptions, we found that, despite a significant increase in activity between the years 2014 and 2015, the underlying processes leading to eruptions possibly remained the same. The best fitting probability distribution is a log-logistic distribution, which indicates that two competing processes influence the timing of eruptions.
