- Svartsengi volcano update: new eruption started, lava already crossed main road
Nov 21 2024 at 1:44 am EST
The new eruptive fissure and several lava flow tongues propagating east and west (image: Almannavarnadeild ríkislögreglustjóra)A new effusive eruption commenced on the Reykljanes Peninsula last night.
Following a small earthquake swarm in late night yesterday, a new, northeast-southwest oriented eruptive fissure opened between Stóra-Skógfell and Sýlingarfell at 11:14 PM last night. The fissure length is estimated to be about 3 km.
The cluster of several vents is now erupting small lava fountains and lava flows oozing out towards the east and west. The lava has already cut the Grindavíkurveg main road and is currently closed.
According to the Icelandic Meteorological Office (IMO), the eruption appears to have reached its peak. The fissure has ceased expanding, and measurements suggest no signs of increased activity.
The eruption is notably smaller than the previous one that started on August 22, with the current lava flow rate estimated at about 1,300 m³/s, compared to roughly 2,500 m³/s during the August event.
The IMO continues: "What stands out is that seismic activity did not start increasing in the weeks leading up to this eruption, as was observed in previous events. The amount of magma that had accumulated beneath Svartsengi was similar to the amount prior to the last eruption. However, the recent trend indicates that increasingly larger volumes of magma are required to trigger the next event. This suggests that the pattern observed in earlier eruptions may be changing."
The moment the new eruption in #Iceland began....

Nov 20 2024 at 10:00 am EST
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity at Lewotobi Laki-laki remained at a high-level during 13-19 November, producing ash plumes, lava fountaining, and an advancing lava flow on the W flank, and continued to impact residents and transportation. Daily white-and-gray ash plumes rose as high as 2.5 km above the summit and drifted SW, W, and NW. According to the Darwin VAAC ash plumes rose 2.4-4.6 km (8,000-15,000 ft) a.s.l. during 13-16 November, or with maximum above-summit heights of 2.9 km on 13 November and 2.6 km during 14-16 November.
Webcam images captured during dark hours throughout the week often showed summit incandescence. A webcam image from 0013 on 15 November captured either tall lava fountaining or the explosion of incandescent material high above the summit, and incandescent material descending the upper flanks. A webcam image from 0018 on 17 November showed areas of incandescence on the distal part of the W flank lava flow.
The flow advance towards Klatanlo Village (3 km NW) based on a drone overflight later that day. According to a news article BNPB stated that residents from Klatanlo Village will not be permitted to return to their homes due to unsafe conditions and will be relocated. The village will also be prone to potential lahars.
Residents were prohibited within a radius of 7 km from the center of Laki-laki, though on 18 November the extended zone on the SW, W, and NW flanks was reduced to 8 km. Loud rumbling was reported on 19 November.
News articles noted that multiple domestic and international flights in and out of Lombok Airport were cancelled or rerouted on 13 November mainly due to ash from the 9-km-high ash plume produced on 12 November. The Komodo International Airport (313 km W), Frans Xavier Seda Airport (252 km W), H. Hasan Aroeboesman Airport (126 km WSW), and the Soa Airport (190 km W) remained closed, and tourists and residents continued to be moved to other islands by boat.
On 14 November the Gusti Ngurah Rai International Airport (840 km W) cancelled 41 domestic and international flights. As of 2000 on 15 November a total of 6,388 evacuees remained in evacuation shelters across six locations. By 18 November almost all airports had returned to normal operations; the Frans Xavier Seda Airport remained closed.

Instituto Nacional de Sismologia, Vulcanologia, Meteorologia, e Hidrologia (INSIVUMEH) reported ongoing eruptive activity at Santa Maria’s Santiaguito dome complex during 12-19 November with continuing lava extrusion at Caliente dome. Daily explosions (a few per hour) generated gas-and-ash plumes that rose as high as 900 m above the dome and drifted in several directions; cloudy weather during 17-18 November prevented visual observations, though explosions and avalanches were heard. Effusion of blocky lava and collapses of material produced block avalanches that descended the SE, S, and SW flanks.
Collapsed material produced short pyroclastic flows during 14-16 November. Incandescence was sometimes visible during dark hours from avalanches of material at the dome as well as explosions. Ashfall was reported in areas downwind during 15-16 November including San Marcos (8 km SW), Lome Linda Palajunoj (7 km SW), Las Marías (10 km S), Calaguaché (9 km S), and Belén (10 km S).
On 19 November ashfall was reported in Santa María de Jesús (5 km SE), La Muralla (8 km ENE), Zunil (10 km NE), and surrounding areas.

Nov 20 2024 at 10:00 am EST
Instituto Geofísico-Escuela Politécnica Nacional (IG-EPN) reported that an eruption at Reventador was ongoing during 12-19 November. Seismicity was characterized by 66-101 daily explosions, long-period earthquakes, harmonic tremor, and tremor associated with emissions. Daily or near-daily ash-and-gas plumes were observed in webcam images and/or satellite images rising 200-1,200 m above the crater and drifted in different directions.
Incandescent material was observed nightly descending the flanks as far as 1 km below the crater rim. Weather conditions sometimes obscured views, especially on 16 November. Secretaría de Gestión de Riesgos maintained the Alert Level at Orange (the second highest level on a four-color scale).

Nov 20 2024 at 10:00 am EST
Centro Nacional de Prevención de Desastres (CENAPRED) reported that eruptive activity continued at Popocatépetl during 12-19 November. The seismic network recorded 11-52 long-period events per day that were accompanied by steam-and-gas emissions sometimes containing minor amounts of ash. The seismic network also recorded daily tremor, characterized at high-frequency and low-to-moderate amplitude, with periods lasting four hours and 54 minutes to as long as eight hours and five minutes.
According to the Washington VAAC ash plumes were visible in webcam and satellite images during 13-16 November rising 5.8-7 km (19,000-23,000 ft) a.s.l. and drifting mostly SW, W, and NW and occasionally N and NNE. The Alert Level remained at Yellow, Phase Two (the middle level on a three-color scale) and the public was warned to stay 12 km away from the crater.
