  The ongoing seismic unrest beneath the volcano, starting exactly one year ago, has paused. The activity has returned to typical background levels during May this year as it has been showing signs of decreasing trend, including ground deformation. The unrest and shallow earthquakes have likely been driven by a combination of several factors such as magma movement, fault slipping and/or hydrothermal system. The activity found ceased for now. Seismic activity summary About 1750 shallow earthquake events have been measured beneath the center of Lake Taupō since May 2022. The largest earthquake to date occurred on 30 November 2022 with a magnitude M 5.7 at about 9 km below the lake surface. 4 quakes during the period were recorded with magnitudes of 4 or more. The activity can be divided into 5 sections: A. 1 Jan 2022 – 30 April 2022: Pre-unrest. This shows a normal level of earthquake activity B. 1 May – 15 September 2022: Initial period of heightened earthquakes C. 16 September – 29...

 

 

  The volcano showed a dramatic activity today. A strong, dilute pyroclastic flow (gravity-driven mass flow) appeared to descend over the southeastern flank in early this morning. The reason for this torrent is not clear yet, but from previous observations at the volcano, it might come from continuous glowing rock falls on the southern slope and its sudden accumulation and destabilization culminating into pyroclastic density currents as happened today. Pyroclastic flows are deadly, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes. Near-frequent vulcanian eruptions continue to produce ash columns releasing pyroclastic material to approx. 5,8 km-6,1 km (19,000 ft-20,000ft) in the western-northwestern direction. Satellite-based measurements of SO2 concentrations were detected in plumes of about 759 tonnes on 1 March. According to MIROVA Detection System, a high thermal anomaly (497 MW) was detected in satelli...

 

 

 

  The explosive eruption continues at the volcano's summit crater. A vigorous phreatic eruption took place at 14:34 local time on 25 May. The blast was strong enough to generate dark black pumice-and-ash flows caused by an eruption plume collapse. White phoenix clouds - towering wall of cloud rising above pyroclastic torrent - rose about 3 km above the crater and drifted NW. Phreatic explosions form when the ejecta consist solely of old country rock, indicating interaction between water and heated conduit-rocks rather than magma itself. No ashfall has been reported in nearby villages. Such events are nothing unusual on the volcano and occur from time to time, but rarely more frequently than every few months or so.

  The Northern Mariana Islands Volcano Observatory reported an elevated eruptive activity at the undersea volcano. Pressure recordings monitored increased values in underwater on 21 May at 10:10 PM. This follows a plume of discoloured sea water observed above the volcano area on 22 May at 10:43 AM local time. Therefore, the alert level for the volcano is being raised to "Yellow."

The volcano continues at highly elevated levels. The activity has been picking up in the early morning yesterday as a short-term lava-fountaining eruptive episode took place from the summit vent. From the available webcam imagery, lava jets onset appeared to start at about 05:22 local time by an impressive lava fountain of up to perhaps a hundred meters above the crater, following nearly 6-minute continuous bursting fountaining accompanied by ejecting incandescent lava bombs. The eruptive episode calmed down at approx. 05:28 local time. Dense grey ash emissions continued during the eruption and darkened the sky above Puebla town. It seems there have been more episodes like this, and it could be a beginning of a new series of paroxysms. Seismic records registered 1389 minutes of volcano-tectonic tremor and 5 ongoing emissions of water vapor, gas and ash over the past 24 hours. The crater area of the volcano remains closed for climbing as the risk of being caught in sudden explosions is ...

 

 

 

  The effusive eruption at the volcano continues and remains essentially unchanged at elevated levels. The Observatoire Volcanologique de Goma (OVG) reported that the lava continues to keep the flow active on the western flank and slowly advances towards the volcano's edifice. The night-time glow and near-constant emissions are being visible from Goma city. The current activity poses no danger for population so far.
