Etna continues to present an activity at northeast and Bocca Nuova craters this July 30, 2018.
Its prolonged, powerful and very noisy gas emissions are accompanied by ejections of incandescent slags and bombs from a small mouth on the northeast crater floor. The bombs fall back into the enclosure of the crater.
Strombolian activity also continues at Bocca Nuova, which is strongly degassing.

In Fuego / Guatemala, heavy rain and thunderstorms generated lahars on 29 and 30 July in Taniluya, Ceniza, El Jute and Las Lajas barrancas.
The lahars carry an abundant fine and pasty material, mixed with blocks of 2 to 3 meters in diameter, branches and trunks of trees; because of the presence of hot materials from the recent eruption, steam released, and a smell of sulfur; they generate, as they pass, vibrations recorded by the seismographs.
Due to the persistence of the rains, it is likely that lahars also affect the Seca barranca and the Rio Mineral , tributaries of the Rio Pantaleon.

In Kilauea, the situation is unchanged from previous days.
Sea entries are active on a 2 km wide front centered on the now-buried site of Ahalanui Beach Park. The south side of the stream did not show any progress and remains 175 meters from the Pohoiki boat ramp. The western edge of the melt is steaming and may be leaking lava
