Fuego - the strombolian activity 28.07.2016 / 5:45 - INSIVUMEH

The eruptive phase began on July 28 at Fuego continued during the night and in the morning of 29 July.

The observatory OVFGO reports fountains of lava high 500 meters above the crater, which feed lava flows reaching about 3,000 meters in the ravines Santa Teresa and Las Lajas. This activity is accompanied by explosions, impacts and shock waves. The eruptive plume reaches 5,500 meters a.s.l., then moving westward over about thirty kilometers. Ash falls were reported on San Pedro Yepocapa.

The Observatory considers this eruptive phase as one of the strongest and most energetic of the 11 previous, with the risk of pyroclastic flows in the ravines, where it is advisable not to park.
