Etna (Sicily, Italy): The effusive eruption from the new fissure vent at the southern base of the SE crater complex continues into its 3rd week of activity with little changes since it started early on 16 March. The lava flow remains active, but at low effusion rate. It has formed a wide channel of 'a'a lava that passes between the Monte Supino and the 2002 craters (Monti Barbagallo), where it forms several overlapping branches. From 2800 m elevation, it has roofed itself over into a tube, but reappears at the surface further downslope. Its most advanced front is now at around 2300 m elevation on the SW flank. ...

Klyuchevskoy (Kamchatka): The activity of the volcano has increased during the past days, with explosive activity at the summit producing intermittent, but relatively intense steam and ash plumes. Based on satellite and webcam data, this new eruptive phase began on or shortly before 28 March. KVERT also raised the aviation alert level to yellow that day, and a day later to orange. Today, Tokyo VAAC reported a plume to 25,000 ft (7.5 km) altitude, i.e. rising about 3000 m above the summit, and drifting into NE directions. ...2 Apr: Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: VA EMISSIONS CONTINUING OBS VA DTG:02/1120Z
Fuego (Guatemala): A new paroxysm (short-but intense eruptive phase with lava fountaining), the 3rd in 2017 so far, has occurred over the weekend and ended a short time ago. Activity has gradually increased during the past days, with explosions becoming stronger and more frequent. Since 31 March, strombolian-type explosions, with ejections up to 300 m above the summit crater, have become near-constant, producing abundant rock falls mainly to the east and southeast upper flanks of the volcano. The peak phase with pulsating lava fountains and lava flows began in the morning of 1 April (local time) and lasted approx. 16 hours, before sharpy dropping after past midnight. ... [read more] ... [show less] 3 lava flows have descended the eastern, southeastern, and WSW slopes, through the Las Lajas, Taniluya, and Santa Teresa gullies, respectively, and reached a length of approx. 3,000 meters. Ash plumes rose to approx 5,000 m altitude and drifted west. Ash falls occurred in up to 80 km distance, including the area of Lake Atitlan, Chicacao, Mazatenango, Retalhuleu, El Palmar and other places.
Nevados de Chillán (Central Chile): The volcano continues to produce infrequent explosions, probably phreatic in nature, from time to time. After two weeks of quiet, new ash emissions occurred in two pulses from the volcano yesterday morning. The first one started from around 12:35 local time and lasted about 10 minutes. It was relatively intense and generated an ash plume that dispersed towards the SSE. A smaller emission occurred at 13:55 local time, but was much smaller. ... [read more] ... [show less] A hot spot at the crater has become visible on infrared camera images during the past days. This is probably caused by hot gasses escaping at this vent. Whether this means a significant change in the eruptive activity of the volcano in the near future is questionable. Hot fluids circulating inside the upper volcanic edifice (the hydrothermal system) have been disturbed by a small magma intrusion at shallow depth for some time, with varying intensity. An increase in this activity resulting in the currently observed hot gas release is not necessarily a sign or precursor of magmatic eruptions, although a further increase in activity cannot be excluded.
Erta Ale (Danakil depression, Ethiopia): The activity remains very elevated at the volcano. Since the start of the (still ongoing) flank eruption in January, a second lava lake has formed at the flank eruption site and a growing lava field is active about 2-3 km northeast of it. According to ground information and fresh high-resolution satellite imagery analyzed by Culture Volcan, the eruption continues to be significant and occurs from both the summit (lava lake in the southern pit crater) AND the fissure eruption site on the southern rift axis. ... [read more] ... [show less] The summit lava lake, which first had dropped to about 100 m depth at the beginning of the flank eruption, had again risen to 40-50 m below its rim when observed by our latest group to the area in late February. The collapsed northern crater showed a short-lived heat signal around 10 March, suggesting a brief phase of activity (lava effusion ?) there, but this seems to have ceased. The most significant activity is occurring on the southern rift at the site of the 21 Jan fissure eruption. The vents feed both a large second lava lake, approx. 175x80m wide, and a growing lava flow field to the northeast, with a width of approx. 1500 m and its most advanced from about 3500 m distance.
Ambrym volcano photos: Ambrym (Vanuatu) is one of the most active volcanoes in the world. Its vast caldera has an amazing moonscape and several active vents that contain boiling lava lakes, most famous Marum and Benbow.
