Sangeang Api (Indonesia): The volcano continues to extrude a lava flow and produces a steam-and-ash plume that rises several 100 m from the crater. Seismic activity remains high.
Our correspondent Aris visited the island briefly a few days ago and shared some impressive images of the new lava flow as well as of the devastation caused by the pyroclastic flows that traveled down the volcano during the massive eruption on 30 May.

Poas (Costa Rica): (23 Jun) Phreatic explosions from the acid crater lake continue to occur at the volcano. During a field campaign on 18 June, OVSICORI scientists observed 5 eruptions during 3 hours. Some of them damaged solar panels of measuring instruments.
A strong eruption on 20 June ejected a dense plume of steam and mud up to 200m above the lake. As the pictures show, it also produced a circular base surge (fast-traveling turbulent pyroclastic flow), typical for explosive magma-water interaction.

Ubinas (Peru): Activity has been lower during the past days. Ash emissions have become less frequent and smaller.

Piton de la Fournaise (La Réunion): (23 Jun) The new eruption at the SE flank of the Dolomieu crater appears to have ended already during the night Saturday to Sunday 22 June. It had produced a series of small lava flows that traveled down to the base of the cone and remained well inside the Enclos.
It was one of the volcano's shortest and smallest eruptions in recent years, which is surprising given the relatively long interval of repose.
