The amazing show at Europe's most active volcano goes on! Read more...Following the amazingly regular pattern of paroxysms (fire-fountaining episodes) at almost identical intervals of around 35-48 hours, the 6th eruption in a row is now in full swing!
It seems to follow exactly the patterns observed during the previous events. Accompanied by increasing volcanic tremor, explosive activity from the New SE crater began to rise slowly this evening, and has now developed into tall, sustained lava fountains now reaching 500-700 m of meters in height, but still increasing!

After the extremely powerful paroxysm (lava fountaining episode) during the night 22-23 Feb, which came as the 5th in a row at very regular intervals, many people around the world are probably wondering whether the volcano will continue this remarkable series of rhythmic eruptions. Read more...If the last interval is an indicator as to when to expect a new paroxysm, it might well be in the course of the next night - something volcanologists, but also thousands of nearby residents, volcano spotters, and many more people from all over the world via webcams are certain to follow closely.
Since the end of the most recent activity, Etna has returned to intermittent mild summit activity from at least 4 of its summit vents, and volcanic tremor levels, kindly provided in real time by the National Institute of Volcanology and Geophysics (INGV) in Catania, are currently low. When this changes, be prepared for another show of fire! What we don't know from the publicly available data is whether the volcano currently inflates, which would be an indication that the volcano is about to recharge itself. This leaves us with the fun to speculate! [less]

Etna (Sicily, Italy): (23 Feb) Once more, Etna produced a very impressive show of unsurpassed fireworks at night: The - awaited - 5th lava fountaining episode (known as paroxysm) occurred late at night and turned out to be particular violent, equal or even stronger than the previous one 48 hours earlier. It was the 5th in a row during a single week's time! Read more...The events building up to the eruption were quite typical and similar to the previous paroxysms: at first, the until-then intermittent and mild strombolian activity from the New SE crater gradually picked up, starting from around 10 pm local time. At the same time, volcanic tremor started to show a steep increase, sign of magma moving upwards inside the volcano's conduits.

Yet another phase of lava fountaining, or paroxysms, is almost certainly about to start now. Volcanic tremor has started to rise sharply from low to now already high levels, and strombolian activity at the eastern vent of the New SE crater is becoming more and more intense and near-continuous. Read more...The 5th paroxysm in a row and within a single week comes after a slightly longer interval, approx. 48 hours, than the very regular roughly 35 hours intervals between each of the previous four events.
Given that the last one was very intense compared to the first three, it might not be surprising. Maybe the time to recharge or reproduce the right conditions deeper below for a new gas-rich batch of fresh magma to start rising just took a bit longer. [less]

Etna (Sicily, Italy): Last night's eruptive episode of tall lava fountains, known as paroxysm, turned out to be one of the most impressive and powerful in recent years. Not only did it produce higher fire fountains than usually, but also it lasted longer than most other paroxysms. Read more...Around 10:30 p.m. local time, volcanic tremor and strombolian activity from the New SE crater began to increase drastically. Half an hour later, a first lava flow started to descend from the eastern summit vent of the crater, and activity continued to increase, soon forming fountains of a few hundred meters tall.

Around 10:30 p.m. local time, volcanic tremor and strombolian activity from the New SE crater began to increase drastically. Half an hour later, a first lava flow started to descend from the eastern summit vent of the crater, and activity continued to increase, soon forming fountains of a few hundred meters tall.
However, instead of peaking (and decreasing) very soon, activity continued to increase and first reached its climax at around 00:30 this morning, with fire fountains reaching the incredible heights of 800-1000 m! Thanks to the near-absence of wind, a tall eruption column of over 10 km height formed with a circular umbrella cloud at the boundary between troposphere and stratosphere (see attached image by Massimo Lo Giudice on facebook) [less]

Since the end of the impressive lava flow from the summit crater, which had been active for several months, but ceased in early February this year, the volcano rested only about 2 weeks before starting its current new eruption.
Russian volcanologists reported that new cinder cones have been forming around the new flank vents. Lava flows at the surface can be seen on satellite imagery. [less]

Lava fountain from Etna's New SE crater during the paroxysm on 20-21 Feb 2021 (image: thermal webcam INGV Catania)
A lava flow has started to descend towards the Valle del Bove and although obscured by the night, a tall ash and steam plume is rising above the summit region of the volcano. As spectacular as it looks, these eruptions pose no threat to inhabited areas, although the ash plumes can be dangerous to aircraft and the lapilli and ash falls are a (rather common) nuisance to the downwind areas around the volcano.
It is remarkable to see that tonight's paroxysm came at almost exactly the same interval as the intervals between the preceding paroxysms on 16 Feb evening, 18 Feb early morning, and 19 Feb late morning, i.e. each approx. 35 hours after the previous one. [less]

This afternoon, Etna produced a very spectacular lava-fountaining eruptive episode, known as paroxysm. Read more...
Starting from around 5 p.m. local time in the afternoon, the strombolian activity, which had been going on for the past weeks from the New SE crater intensified significantly. Shortly after, a lava overflow was observed from the eastern side of the South East crater. At 16:05 UTC (5:05 p.m. local time), a part of the eastern flank of the cone collapsed into a pyroclastic flow that traveled down the western wall of the Valle del Bove depression.
The flow, as hot material was sliding over snow, produced an ash and steam cloud that quickly dispersed from high altitude winds to the south. [less]

Laki, Iceland – The 1783-1784 fissure eruption produced a haze that engulfed most of Europe. Large quantities of aerosols emitted during the effusive fissure eruption resulted in a significant global volcanic-induced cooling episode, with climate impacts felt thousands of miles away in locations such as China and Japan. It is suggested that this eruption and the resulting crop failures/ famine triggered the French Revolution (1789-1799) (Image: A.Robock on EOS).
Volcanic eruptions are the most significant natural radiative forcing on Earth’s climate system. During large explosive eruptions, huge quantities of sulphur aerosols are injected into the atmosphere, encircling the planet. This reduces incoming solar radiation and alters the energy balance, consequently causing an overall decrease in global mean surface temperature. It produces, what is commonly termed, a ‘volcanic cooling episode’. Large tropical eruptions, such as Tambora 1815, Krakatoa 1883 and Pinatubo 1991, typically produce the greatest climatic impacts due to their equatorial location. However, high-latitude eruptions such as Laki, Iceland 1783 should not be overlooked as these can still have significant impact on global climate.

Example of Alaskan May–August temperature reconstruction using MXD method, a pronounced cold anomaly is clear following the eruption of Laki, Iceland in 1783. Lower left inset shows annual ring width increments in white spruce from Alaska with dates highlighted. MXD measures the peak density value in the latewood of each year. Note very low density in 1783 in this wood section (Image: D’Arrigo et al. 2013).

The extrusive actively lava dome continues to grow at moderate to high levels triggering the incandescent avalanches (block-and-ash flows) caused by gravitational collapse of the lava dome that traveled over the E-SE and S slopes about 500 m-1,500 m distance from the summit. Collapsing parts of the flow generated a small avalanches that lifted ash plumes (so-called phoenix clouds) as it descended the slope.

Unrest continues at the volcano. During the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) recorded a total of three (3) rockfall events most likely caused by volcanic quakes and ongoing ground deformation along the slopes of the volcano. Read more...
The slopes "inflate" due to rising of the molten magma underneath. This may also cause additional effects such as an increased release of SO2 and steam plumes.
Mayon remains at Alert Level 1, "which means that it is at an abnormal condition. Although this means that presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the 6-kilometer radius Permanent Danger Zone (PDZ) due to the perennial life-threatening dangers of rockfalls, landslides/avalanches at the middle to upper slope, sudden ash puffs and steam-driven or phreatic eruptions from the summit."

Significant actively growing lava dome in the inner summit crater of Sinabung volcano (image: @jaimessincioco/twitter)
The extrusive actively lava dome continues to grow at moderate to high levels. This relatively intense effusive phase causes near-constant gravitational collapse of the lava dome triggering the block-and-ash flows (pyroclastic flows) that lifted ash plumes (so-called phoenix clouds) as it descended the slope.
A current volume of the growing lava dome has reached 4 million m³. [less]

The extruded lava dome is about 93 m tall, 231 m wide and 511 long and had a volume of 5.93 million cubic meters by 1 February reported by the University of the West Indies Seismic Research Centre (UWI-SRC).
On 1 February a gas measurements revealed the presence of sulfur dioxide (SO2) emissions, first since the eruption started. The absence of sulfur dioxide (SO2) emissions in the early stages of the eruption was due to the interaction of SO2 with the groundwater as SO2 dissolves in groundwater. The gas escaping suggests that the groundwater is drying up. [less]

The explosive activity of the volcano continues at elevated levels since 21 January as the alert level was raised to "orange". Read more...
The volcano generates near-constant emissions of ash, gas and steam from the summit vent that rose to estimated 14,000 ft (4,300 m) altitude. Volcanic ash is dispersed towards the east and south.
The explosive eruption of the volcano is accompanied by frequent steam glow visible from the summit crater at night. Glow suggests continued rise of fresh magma that could be rising inside the volcano's conduits. [less]

Over the last year, a series of thermal infrared images have been regularly collected by helicopter to observe the temperature of steam and gas vents as reported GNS volcanological observatory. Temperatures have shown a gradual decline since the December 2019 eruption, from over 700 °C in February 2020 to 300 °C on 21 January 2021. The gas emission temperatures are now similar to temperatures measured in July 2018. Read more...During January 2021, GNS Science continued monitoring of Whakaari/White Island by observation flights and measurement of gas emission rates, and with automatic earthquake, camera and ground deformation observations. Recent observations confirmed no evidence of recent eruptive activity, or signs of collapse in or near the active vents. There is little water ponded on the floor of the 1978/90 Crater.
Volcanic steam and gas continue to be emitted from the active vents and lava extrusions in the area that erupted in December last year. The most recent observations are some of the lowest gas emissions measured since the 2019 eruption and are now close to those observed in early-2019. [less]

Shiveluch (Kamchatka): Water is a key ingredient for fuelling explosive volcanic eruptions. Water-rich magma contains higher proportions of volatiles (gases), increasing buoyancy and therefore driving the upward movement of the magma to the surface. The increase in gases within the magma also increases the pressure, causing the explosive nature of eruptions with this magmatic composition.

New research published in Contributions to Mineralogy and Petrology has found that the world’s most active volcano, Shiveluch, located on the Kamchatka peninsula in Far Eastern Russia, contains much more water within its magma than previously suggested.
This invaluable finding could help scientists gain better insight into other volcanic plumbing systems around the world, particularly of other notoriously explosive subduction zone volcanoes, as well as helping them further understand the global water cycle.

The activity of the volcano remains stable at low levels characterized near-constant degassing from the crater. Emissions of water vapor and gases generated a white dense ash column rising several 300 m above the summit as can be seen in the video. Read more...
The small lava pond in the summit crater, first observed in Nov last year, has remained essentially unchanged.
Its currently stable condition suggests that there is a delicate equilibrium between heat and magma supply and loss (through cooling and mild emissions during degassing). [less]

The effusive eruption of the volcano continues and has remained essentially unchanged at moderate levels. Read more...The western fissure continues to supply the lava into the growing Halema‘uma‘u lava lake.
According to the Hawaiian Volcano Observatory (HVO) a north-south trending line of surficial cracks divides the boundary between the western active portion (left) and eastern stagnant portion (right) of the Halema‘uma‘u lava lake. Lake depth measurements from 28 January on both sides of the cracks (near center) indicate that the eastern portion of the lava lake is 4 m (13 ft) lower than the western portion of the lava lake. In contrast, the stagnant eastern portion is a duller gray with several smaller islands visible. North of the cracks (upper center), the top of the inactive northern vent spatter cone is nearly submerged by the rising lava lake.
