"RVO reported that activity at both Manam's Southern Crater and Main Crater was low during 1-18 March although inclement weather made crater observations difficult; no noises were reported. Seismicity had slowly and erratically increased since 28 February, peaked on 13 March and remained at that level through 15 March, and then increased again through 18 March. The seismicity was characterized by small-to-moderate, sub-continuous, and continuous volcanic tremor. Discrete low-frequency earthquakes were also recorded." [less]

Eruption at Turrialba yesterday (OVSICORI-UNA)
The first eruptions occurred yesterday starting around 11 am local time, producing plumes that rose 500 m and drifted west to cause ash falls in the capital San José.
A second pulse of activity occurred from 13:38 to 14:24, with ash plumes increasing to up to 1 km height. A part of the southern crater wall was breached by one of the stronger explosions, and a new fumarole field appeared in the breach. [less]

Steam plume from Tungurahua volcano
Since 17 Feb, a gradual increase in seismic activity has been recorded, including the appearance of frequent volcano-tectonic earthquakes since 21 Feb, which reflect rock fracturing, likely caused by pressurized magma intruding into the plumbing system.
A small explosion was reported on 18 Feb, and SO2 emissions, also tell tale of fresh magma approaching the surface, were detected. Moderate inflation at the summit was measured as well. [less]

One lava flow traveled 1.6 km S down the Trinidad drainage and another traveled 600 m W down the Santa Teresa drainage. The eruption produced rumbling and train sounds audible up to 12 km away. Ash plumes rose 850-1,250 m above the crater and drifted 35 km W. Read more...
Ashfall was reported in nearby areas including Panimache (8 km SW), Morelia (9 km SW), and Santa Sofía (12 km SW). During 28 February-1 March explosions generated ash plumes that rose an average of 650 m and drifted 9-10 km W. Incandescent material was ejected 150 m above the crater, and a small lava flow (400 m long) descended the Trinidad drainage.
INSIVUMEH noted that the effusive phase had ended at 2156 on 1 March. Ash plumes from explosions rose 550-750 m and drifted 10 km W on 2 March and SW on 3 March. [less]

Explosions on 26 February ejected incandescent tephra 700 m away from the crater onto the N and NE flanks. Ashfall was noted in Domingo Arenas, San Martín Texmelucan, and Huejotzingo in the state of Puebla. The international airport in Huejotzingo suspended operations to clean up the ash. Steam, gas, and ash plumes drifted NE.
On 27 February explosions generated ash emissions and ejected incandescent tephra 300 m onto the flanks. Ashfall was reported in Huejotzingo, Domingo Arenas, Tlaltenango, San Andrés Cholula, and Puebla. During an overflight that same day, volcanologists observed dome number 55 which had grown and was filling the bottom of the inner crater. The dome was 250 m in diameter and at least 40 m thick, putting it about 60 m from the bottom of the main crater floor. The volume was an estimated 1.96 million cubic meters. The volcanologists also observed a small explosion that produced a 1.5-km-high ash plume. [less]

Volcano Special Tours: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
Photos from Kamchatka: Kamchatka in Russia's far east is one of world's remotest regions and has an almost unparalleled density of active volcanoes. Look at photos taken during our expeditions from this wonderful corner of the world!
