Svartsengi (Reykjanes peninsula, SW Iceland): The Icelandic Meteorological Office (IMO) reported that by 23 September around 10 million cubic meters of magma had accumulated beneath Svartsengi since the last eruption within the Reykjanes volcanic system ended on 5 August. Data showed that magma was accumulating at around 4 km depth. The rate of magma accumulation was steady; model calculations based on deformation measurements indicated that by 27 September the volume may reach 11 million cubic meters, a volume that in some previous cases was followed by eruptions.
Since the likelihood of an eruption had increased, IMO raised the Volcanic Alert Level System (VAL) to 2 (on a scale of 0-3) on 25 September and concurrently a risk assessment map of the area was also updated.

A magnitude 4.8 earthquake near Pagar Alam, Lahat Regency, Sumatera Selatan, Indonesia, was reported only 8 minutes ago by Indonesia’s Meteorology, Climatology, and Geophysical Agency, considered the main national agency that monitors seismic activity in Indonesia. The earthquake occurred at a moderately shallow depth of 31. km beneath the epicenter in the afternoon on Thursday, October 23rd, 2025, at 5:37 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 4.8 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Pagar Alam (pop. 70,400) located 85 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Bengkulu (pop. 373,600) located 107 km from the epicenter, and Bengkulu (pop. 373,600) 107 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant
