A visit of volcanologists to Etna in the evening of August 28, 2018 allowed to control the activity summit.

The incandescence presented by the Bocca Nuova is intense, despite an activity that is not the highest; the second internal mouth of the crater, called "BN-2 / La Spagnola" is also active.

At New Southeast Crater, the "Puttusiddu" has a weak but continuous, effusive and Strombolian activity.

On the island of Manam volcano in Papua New Guinea, the situation is critical for the remaining inhabitants: more than 5,000 people have no food or drinking water since the eruption last Saturday. Cultures, coconut palms and banana trees are damaged or destroyed under the weight of ashes.

Many houses were destroyed, crumbling under the weight of ashes, reaching in places 11 cm thick.

The local government president confirms that the villages of Yassa, Madauri, Baliau, Kuluguma, Boda and Waia have been affected by the fallout of ashes, and that the village of Dangale has been flooded by a pyroclastic flow.

In Guatemala, heavy rainfall has generated lahars in Las Lajas, Honda and El Jute barrancas del Fuego.

These lahars are hot, have a sulphurous smell, and carry cement-like materials and blocks with a diameter of 50 cm to 2 meters. They remain qualified as moderate by Insivumeh and Conred.
