Volcanic activity worldwide 13 Jul 2023: Fuego volcano, Popocatépetl, Merapi, Reykjanes, Reventador…

Map of today’s active volcanoes

Eldey (Reykjanes Ridge, Iceland): Icelandic authorities have closed the access to the eruption area, partially because of dangerous levels of gas measured, partially because of some risk-taking individuals who tried to get very close to the vents, putting themselves at (avoidable) unreasonably great risk of accidents.

Fréttastofu bárust myndir af ferðamönnum sem gengu á hrauninu upp að gígnum. Gosstöðvum hefur verið lokað til laugardags, bæði vegna veðurs og hegðun fólks. Gígbarmar gætu brostið og hraunkvika streymt fram að fólki sem hættir sér nærri gosinu. Myndina tók Mateusz Krasucki. pic.twitter.com/idctyZ3ly3

…13 Jul:
The effusive rift eruption near Litli-Hrútur north of Fagradalsfjall volcano continues with little changes at relatively low intensity.
A small section of the original eruptive fissure remains active and produces small fountains from a growing spatter rampart and feeds a slowly increasing lava flow field.
The area is accessible via a 10 km one-way trail from the southern coastal road.

Fagradalsfjall (Reykjanes Peninsula, Iceland): Icelandic authorities have closed the access to the eruption area, partially because of dangerous levels of gas measured, partially because of some risk-taking individuals who tried to get very close to the vents, putting themselves at (avoidable) unreasonably great risk of accidents.

…13 Jul:
Overwhelming footage of the eruption onset was released.
A drone captured a ground opening immediately after the new magma batch erupted onto the surface associated with abundant SO2 emissions and glowing ejecta being thrown several meters in various directions.

This is hands down one of the rarest volcano footage I’ve ever seen and possibly the first and only drone shot in the world showing a volcanic fissure opening up in real time. This was captured in Iceland two days ago by Jakob Vegerfors – shared with his permission. pic.twitter.com/PWbGtgC1G4

Ebeko (Paramushir Island): The explosive eruption at the volcano continues.
The volcano continues to produce minor, sometimes powerful vulcanian-type eruptions accompanied by ash plumes with an average altitude of 10,000 ft (3,048 m) as took place today.

The spewed ash was spread to the east-southeast of the volcano.

Sakurajima (Kyushu, Japan): (13 Jul) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20230713/0428Z FL070 EXTD E OBS VA DTG:13/0420Z

Mayon (Luzon Island, Philippines): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20230713/2004Z VA CLD UNKNOWN REPORTED OBS VA DTG:13/2000Z

Merapi (Central Java, Indonesia): (13 Jul) The eruption at the volcano continues at relatively intense levels. Maga rising to the summit crater accumulates as a dome that overspills the half-open summit crater to the southern and southeastern flanks, generating frequent incandescent avalanches and turbulent hot pyroclastic flows.
In the past 24 hours, the volcano produced 16 avalanches that reached up to 1,800 m length on the southern slope, traveling mainly through the Bebeng river, according to a local newspaper citing information from the Centre for Volcanology and Geological Hazard Mitigation (PVMBG).

Shishaldin (Aleutian Islands, Alaska): (13 Jul) Highly elevated temperatures continue to be detected in the inner summit crater of the volcano, the AVO reported.
A night-time glow was detected through a surveillance camera last night associated with SO2 emissions.

Periods of amplitude volcanic tremor have increased over the past 24 hours.
These observations might suggest a presence of magma beneath the crater, which led scientists to rise the alert level for the volcano to Orange, immediately after rising the alert to Yellow yesterday.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 and is moving at 20 kts in W direction.
The full report is as follows: ONGOING VA EMS, REMNANT VA to 21000 ft (6400 m)

Fuego (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: VA EMS OBS to 15000 ft (4600 m)

Nevado del Ruiz (Colombia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 .
The full report is as follows: NEW VA EMS to 21000 ft (6400 m)

Sangay (Ecuador): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: NO VA EMS

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 .
The full report is as follows: VA EMS OBS to 14000 ft (4300 m)

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 23000 ft (7000 m) altitude or flight level 230 and is moving at 15 kts in E direction.
The full report is as follows: SPORADIC EMISSIONS to 23000 ft (7000 m)

Villarrica (Central Chile): The activity of the volcano continues at stable levels.
The latest images from local observers depict beautiful night-time glowing steam and gas emissions confirming active small lava ponds within the summit crater characterized by a delicate equilibrium between incoming and consumption of magma and even passive emissions of ash. The thermal anomaly in the inner summit vent is identified in the latest Sentinel-2 satellite image.

Piton de la Fournaise (La Réunion): The effusive flank eruption at the volcano continues without significant changes over the past few days.
The steep-sided spatter cone, already formed above the main SE fissure vent, continues to be built by ejecting hot, juvenile and plastic lava clots, throwing them onto the volcano’s slopes.

Emissions of lava have been feeding mostly the upper part of the Grandes Pentes flank at 1500 meters altitude over the last night. Since 7 July, the lava flow field has widened by 180 meters and thickened, primarily at its northern section. The lava flow front remains about 1.8 km from the main road and appears to stopped or at least waned its advance. Most lava continues to travel directly into lava tubes, occurring in the vicinity of the cinder cone, and essentially remains hidden from view.
The latest lava flow discharge rate is estimated to be about 1 and 13.5 m3/s over the past 24 hours using the HOTVOLCC platform. The total lava flow volume is estimated at approx. 6 (± 3) million m3 so far.
