The explosive activity at the volcano continues.
Small to moderate near-frequent strombolian eruptions continue to be produced, ejecting lava bombs landing inside the crater. Besides that, constant passive emissions of steam and gas ("venting") continue.
A satellite image from 16 March shows the ongoing glowing inner summit area and gas emissions hinting rise of fresh juvenile magma in the conduit.
The Volcanic Alert Level remains at Level 2. The public was reminded not to enter the restricted area within 600 m around the cone, defined by Danger Zone A on the hazard map.

Santiaguito volcano (Guatemala): glowing avalanches and vulcanian eruptions from lava dome continue

Aerial view into the Caliente lava dome while erupting (image: Diego Rizzo)
Aerial view into the Caliente lava dome while erupting (image: Diego Rizzo)

The extrusive-explosive eruption of the volcano continues at high levels.
A visible night-time glow and near-constant emissions of gas and water vapor (so-called degassing) indicate the continuing rise of fresh viscous magma accumulating into the Caliente lava dome. Pilling lava material makes the dome partially prone to collapse, which in turn develop into rolling hot weak-to-moderate avalanches in the S direction and incandescent dome blocks in the W-SW direction along a steep ravine.
The explosive activity is characterized by near-constant weak-to-moderate vulcanian-sized eruptions at roughly regular intervals of about 1 to 2 per day. Viscous, but gas-poor magma squeezes through the main conduit in search for the fastest way up to the surface and is being fragmented into grey ash-rich eruption plumes, reaching an average height of about 14,000 ft-15,000 ft (4,3 km-4,6 km).
People are advised to avoid the sticky lava flow due to the strong heat which may cause burns and other serious injuries. The current hazards are also hot avalanches that can become mobilized into hot glowing currents (pyroclastic flows).

Ash-rich explosion from Bezymianny volcano this morning (image: KVERT)

The activity at the volcano has been gradually increasing over the past few hours.
A new explosion appeared from the summit, starting early this morning, at about 06:25 local time, the local institute KVERT reported.
The eruption sent a grey ash column to nearly 13,000 ft (3,900 m) altitude that extended about 25 km towards the northeast.
Furthermore, according to the KVERT observatory, there is a likelihood of a new viscous lava block that is being squeezed out from the actively growing lava dome and appears forming a "dome on top of a dome".

Villarrica volcano (Central Chile) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 March-28 March 2023 (Continuing Activity)

The eruption at Villarrica was ongoing during 21-28 March. POVI reported that on 21 March Strombolian explosions ejected material 100 m above the crater rim. SERNAGEOMIN reported that at 0551 on 24 March a long-period earthquake was associated with low-intensity crater incandescence.
According to POVI a cone with a vent that was about 13 m in diameter had formed on the crater floor and was visible during a recent overflight. Sometimes lava fountains rose over 100 m. At 2249 on 26 March Strombolian explosions ejected incandescent material more than 110 m above the crater rim.
The Volcanic Alert level remained at Yellow (the second highest on a four-level scale) according to SERNAGEOMIN. SENAPRED maintained the Alert Level at Yellow (the middle level on a three-color scale) for the communities of Villarrica, Pucón (16 km N), Curarrehue, and Panguipulli, and SINAPRED maintained an exclusion zone of 1 km from the crater.

Stromboli volcano (Aeolian Islands, Italy) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 March-28 March 2023 (Continuing Activity)

INGV reported that both explosive and effusive activity at Stromboli occurred during 20-26 March, though inclement weather conditions prevented views on most days. Activity was centered at three vents in Area N within the upper part of the Sciara del Fuoco, and from four vents in Area C-S (South-Central Crater) on the crater terrace. Explosions at two vents in the N1 crater and one vent in the N2 crater in Area N were low to medium intensity and ejected coarse material (bombs and lapilli) 80-150 m at a rate of 6-12 explosions per hour.
Explosive activity at three active vents at the S2 sector in Area C-S ejected coarse material generally as high as 150 m above the vent at a rate of 5-7 explosions per hour; material was ejected as high as 300 m on 23 March. Sector C was characterized by occasional low-intensity explosive activity through the week and intense spattering on 22 March. No activity was recorded at sector S1.
A strong explosion at 1549 on 25 March at Area C-S and was followed by two minor explosions; the sequence lasted about three minutes.



A lava overflow event at one of the N1 vents began at 2242 on 23 March and was preceded by spattering activity in Area N. After about an hour lava flowed along the Sciara del Fuoco in the ravine that had formed in October 2022. The flow rate notably increased during 0200-0400 on 26 March and caused avalanches of material from collapses at the advancing flow front.
By that afternoon the flow was cooling down and no longer being fed. It was unknown due to weather conditions if material reached the coastline.

Santa Maria volcano (Southwestern Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 March-28 March 2023 (Continuing Activity)

INSIVUMEH reported that the Santa Maria-Santiaguito lava dome complex remained highly active during 22-28 March. On most days steady degassing from the dome produced gas plumes that drifted S and SW. Incandescence from the dome and along lava flow margins was visible most nights or early mornings.
The lava flow that extended 4.3 km down the SW flank in the San Isidro and Zanjón Seco drainages was active. Activity from the lava dome included explosions and avalanches, and small pyroclastic flows during 22-23 March. Daily weak to moderate explosions generated ash plumes up to 1 km above the crater that drifted SW and W, and avalanches traveled down multiple flanks.
