Sangay volcano (Ecuador): emissions of ash and lava flow continue

The effusive-explosive eruption of the volcano continues.

The lava continues to emerge onto the SE flank ravine, keep the flow active and slowly advance nearly to the base of the edifice.

Near-frequent vulcanian eruptions continue to produce ash columns releasing pyroclastic material to approx. 6,1 km (20,000 ft) elevation in the western-southwestern direction. Most of the ejected hot, juvenile and glowing material slid down along the southeastern flank in the form of incandescent avalanches.

Heavy rainfalls occurred in the area of the volcano. Nonetheless, no debris avalanches and/or lahars were detected. In addition, the flow rate has increased in the Upano river. The current hazards pose lahars (mud flows) which could also occur if heavy rainfalls remobilise the fresh ash deposits.
