Following the final effusive period of 2016 a fairly rigourous explosive phase commenced in early January. Seven major Vulcanian explosions occurred producing pyroclastic density currents and extensive ballistic fallout, which is being studied at CIIV. The PDC with the largest run out went down La Arena reaching 4.2 km. As with previous eruptions, the main ballistic field is located to the north within the Playon. The photo shows the final event on the 3rd Feb. A PDC can be seen heading down La Arena.
