PEVOLCA in a press release admits that significant inflation has been observed since the onset of the seismic swarm, confirming that the cause of it is new magma. Although it is not certain at all that it will, an eruption should be expected to occur any time now. The most likely area is probably the El Julan coast or further south in the Las Calmas Sea.

"Infrared imagery from the Metop satellite showed a possible rising steam plume from the area of Siple on 20 June. The imagery, as interpreted by Mark Drapes, indicated that the volcano was about -22 degrees Celsius, about 6 degrees warmer that the surrounding landscape, and the base of the plume was about -55 degrees Celsius.

Mexico:
Gas and steam venting picked-up at Popocatepetl volcano in the past 24 hours. The seismic signals from a train of exhalations is visible on the enclosed seismogram beginning at 16 UTC. SO2 output from the volcano had increased the past few days. [less]

If what caused this activity is fresh magma rising from the mantle beneath El Hierro, it now has moved a few km more to the south, but still remains at relatively great depth (20 km). Whether it remains there or continues to move, and perhaps rise towards the surface = cause an eruption, is speculation. [less]

The tremor, a low-frequency ground vibration, is thought to be caused by moving magma. It had been strong yesterday and correlated well with a southward propagation of earthquake locations, suggesting that magma at about 20 km depth flew from underneath the El Golfo area towards the EL Julan (south) coast, in a similar way as before the Oct 2011 eruption, but became blocked there, and did not reach the southern rift zone near La Restinga.
After the cease of tremor in the afternoon, earthquakes still continued at high rate, marking a record figure with over 180 quakes larger than M2 yesterday alone, and more than 150 quakes larger than M1.5 so far today. [less]

Frequent eruptions also occurred from the western vent, with typical ejection heights of 50-100 m, and occasionally up to about 200 m. A third vent in the central crater and rarely a vent at the extreme western end of the crater erupted occasionally as well. [less]

The hypocenter of the seismicity is still relatively deep (around 20 km) though since the volcano has already generated a channel for magma to ascend during the previous eruption in 2011-12, the timeline for rise and eruption of any "new" magma may be much shorter.
[less]

At this point, a new eruption in the near future at or near the previous submarine vent near La Restinga is a real possibility. [less]

So far, there were about 35 quakes mostly around magnitude 2, including 3 at magnitude 3.0-3.1. [less]

23 June 6:30 pm (ET): The Fires of Pele - Hawai'i [less]

Plumes drifted SE on 2 June and NW during 6-15 June. Ash fell in areas downwind between Yassa (WSW) and Baliau (NNW), and Warisi (ESE). Incandescent material was ejected from the crater, and roaring and rumbling noises were noted.
Pyroclastic flows on 16 June (at 0700, 0720, 0722, and 0729) channeled into the SE valley. The last pyroclastic flow was perhaps the largest as it reached the lowest elevation, 300-400 m above sea level, but was far from populated areas. Ash plumes from the pyroclastic flows drifted WSW and WNW; ash fell in Bogia (22 km SSW, on the mainland). Emissions from Main Crater were milder and mostly characterized by white and bluish plumes. Light gray plumes were noted during 2 and 8-9 June. Fluctuating incandescence was intermittently observed and ash fell in the NW part of the island. [less]

Interestingly, a 6.0 magnitude earthquake at 14 km depth occurred in the Aleutians 1200 km to the west from Cleveland 6 hours earlier, but this might be simple coincidence. [less]

Meanwhile the lava lake within Halema‘uma‘u remains at a high level, causing loud cracking and booming sounds sometimes audible from the Jaggar Overlook! At night, glow from this newest crater on the volcano is brighter than ever before in this eruption phase! This is due to continued high pressure on the volcano, also manifesting with an increased rate of extension visible in the summit GPS line over the past 3 weeks. All in all, a great time to visit Kīlauea! [less]

Until now, there were 22 quakes last night and 7 today, including 3 larger than magnitude 2. The depth of the new quakes is around 17.5 km, significantly shallower than during the swarm last week. [less]

Today you may visit the most interesting parts and items of the petrified forest of Lesbos already in one of the best international museum of fossil trees in the village Sigri on western Lesbos island. The natural heritage of the petrified forest of Sigri belongs also to the international UNESCO-Geoparks.

The Indonesian Volcanological Survey recommends a safety zone of 3 km radius around the volcano. [less]

During 6-7 June explosions produced ash plumes that rose 200-500 m above the crater and drifted N, and 12 km S and SW. Lava flows on the SE flank were about 800-900 m long in the Las Lajas drainage, 600 m long in the El Jute drainage, and 250 m long on the SW flank, and produced blocks that rolled and reached vegetated areas. The explosions were accompanied by rumbling sounds and shock waves that were detected in areas 10 km away, including Panimaché and Morelia (~8 km SW).
During 10-11 June an ash plume rose 1.5 km above the crater and drifted 15 km W and NW. Ashfall was reported in Panimaché I and II, Sangre de Cristo (8 km WSW), Yepocápa, and other villages nearby. Lava flows traveled 1.6 km down Taniluyá drainage, 1 km down the Ceniza drainage, and 1.5 km down Las Lajas. Pyroclastic flows descended Las Lajas. [less]

The last eruptions of Tavurvur were in August 2011. [less]

Meanwhile, pressure is still high across other parts of the volcano, with small lava flows and a lava pond increasingly present within Pu‘u ‘Ō‘ō crater (not directly accessible, but glow can be seen from a distance with clear weather), and the summit lava lake within Halema‘uma‘u still at high levels and producing strong glow visible from the Jaggar Overlook after dark. Within this newest crater but still out of sight, there have been spillovers of the lava lake as it continues to overtop its previous high-level banks! [less]

The recent reports from USGS and INSIVUMEH summarize the activity during the past days:
On 1 June, hot lahars traveled down the Las Lajas and El Jute drainages valley on the SE flank, carrying blocks of up to 2 m in diameter. [less]

There is little known about the eruptive history of the volcano except that it most likely has erupted during the past 10,000 years and can be considered an active volcano. Any reawakening would thus mark its first historic eruption, something that would remind what has happened at Chaitén volcano in 2008. [less]

Since the last lateral eruption in March 2007, Stromboli has been in a heightened state of activity overall during most of the past years, indicating that magma levels inside the conduit are relatively high. The question is when again the magma finds its way out through a fissure on the flank on Sciara del Fuoco to produce another effusive eruption with a new lava flow. [less]

-- new activity --- [less]

This possibly indicates that magma is still sometimes moving under the volcano, but unless the intensity of earthquake swarms increases a lot, it is not likely that a new eruption is in the making. [less]

Dduring 21-27 May, people from the village of Maliku noted steaming from the volcano that created white plumes rising 50-150 m above the crater.
A steep increase in seismic activity was recorded on 25 May and CVGHM raised the Alert Level to 3 (on a scale of 1-4) on 28 May. [less]
