Nevado del Ruiz volcano (Colombia): possible explosive eruption (pilot report)
Tuesday Feb 23, 2016 11:54 AM | DOOR: T
This morning, a pilot reported to The Colombian Geologic Service an ash plume from the volcano to 22,000 ft (6.7 km) altitude, which would indicate a moderate explosive activity at the volcano took place.
Whether or not this is the case is unclear at the moment, as sometimes weather clouds are being mistaken as ash plumes, in particular if the observation is at night (as in this case).
On the other hand, mild ash emissions from Nevado del Ruiz have been occurring intermittently during the past months and a somewhat larger emission as reported this morning would not come as a surprise.
