Tupungatito volcano (image: 24horas.cl)
A volcanic-tectonic earthquake of magnitude 3.2 Richter occurred under the volcano yesterday. The epicenter was at 8.2 km depth 25 kilometers northwest of the main crater. This might announce a period of unrest at the volcano. ... [more]
Activity at the Caliente lava dome remains essentially unchanged. Some explosions produced ash plumes of up to 500 m height and the eastern blocky lava flow remains weakly active.
Tue, 18 Aug 2015, 14:39
Activity has decreased during the past days. INSIVUMEH reported only few and relatively weak explosions occurred during yesterday.
Tue, 18 Aug 2015, 14:38
Weak strombolian activity continues inside the Mackenney crater and produces small plumes of gas and light ash. Glow is visible at night.
Tue, 18 Aug 2015, 14:26
Activity has actually decreased and been relatively low at the volcano during the past days. However, the risk of a major eruption remains according to the Japan Meteorological Agency who maintains alert level 4 (preparation for evacuation).
Tue, 18 Aug 2015, 14:15
Thermal signal from Karangetang volcano (MIROVA)
Thermal signals from the volcano have been increasing over the past days, suggesting that the lava output at the summit crater has increased. This could again again to dangerous pyroclastic flows if the lava dome or lava flows become unstable on the steep upper flanks of the volcano. Such flows can easily reach inhabited areas. ...more
During the past months (at least since May) the volcano has been constantly active with a weakly alimented lava flow on the upper southern flank, which has been generating frequent incandescent rock falls. It decreased during July, but a new phase of more violent activity might be in the making now and could make new evacuations necessary. Alert level of the volcano remains at 3 (out of 4). [less]

Mon, 17 Aug 2015, 12:22
No new explosions of significant size have occurred at the volcano during the past 48 hours. Seismic activity remains elevated and suggests that smaller ash emissions continue, however. ...more
Whether this is only a pause before another, possibly more violent phase of the eruption or already an end of this episode is too early to say. Ecuador's ministry of civil protection maintains yellow alert for the communities of Francisco, Rumipamba, San Ramón, Mancheno, José Guango Bajo, and San Agustín del Callo (Mulaló). [less]

Seismic signal of Sakurajima's SKRB station on 15 Aug (V-NET)
Sakurajima (Kyushu, Japan): Japanese volcanologist monitoring the volcano warned that a larger eruption could occur in the near future. The alert level of the volcano was raised to the second highest, 4 out of 5, meaning that preparations for evacuations of nearby areas (within a few km from the Showa crater) are in progress. ...more
The alert was based on a strong swarm of shallow volcanic earthquakes located beneath the Showa crater. The seismic swarm started around 7 am on 15 Aug (local time), and peaked with almost 180 quakes per hour around noon. It gradually waned, but continues with weaker intensity until now. ...

Eruption from Cotopaxi on 14 Aug (photo: Daniel Salazar / twitter)
The volcano started to erupt, for the first time after more than 70 years, on 14 Aug with a series of 6 very strong explosions. The volcano last erupted in 1940 and possibly 1942. A major hazard of glacier-clad Cotopaxi's eruptions are melt-water floods that can turn in to devastating lahars and threaten an area with approx. 300,000 inhabitants. ...more
The first explosion on 14 Aug occurred at 10:50 local time with an ash plume that rose approx. 8000 meters above the summit crater. During the same day, it was followed by 5 more explosions of similar or smaller size. Some of the explosions produced pyroclastic flows. The volcano calmed down a bit during yesterday, but had another explosion in the afternoon. [less]

Raung's summit caldera on 14 Aug 2015
Activity has strongly decreased at the volcano. When we visited Raung during 14-15 August, we observed pulsating, often near-continous ash emissions that produced plumes of several hundred meters. They often consisted of dark jets of ash, presumably from phreatomagmatic activity inside the conduit. ...more
This activity originated from the lower, southwestern vent of the large, double-crater new cinder cone in the eastern part of the caldera. The larger vent to the NE was almost entirely inactive, except two small, very weakly active effusive vents on its inner walls. Occasionally, glowing lava blocks were pushed out from these. The recent lava flow was no longer active. Like a giant pancake, it has completely covered the caldera floor surrounding the large cinder cone. [less]

Seismicity at San Miguel since the beginning of 2015 (MARN)
Yesterday (13 Aug), a new ash emission occurred from the volcano, the first eruptive activity since early this year. Light ash fall occurred in areas up to 10 km west of the volcano in the small towns of San Jorge, Las Moritas and Piedrita. ...more
The volcano, however, had remained in state of unrest during the past months, with both elevated seismic and SO2 degassing activity. In particular, seismicity started to rise again in July this year. A peak occurred on 12 August, a day before the eruption. The volcano remains in institutional orange alert, maintained since December 2013. [less]

After the collapse of the lava dome on 11 July, activity had been almost exclusively effusive and produced a new lava flow on the southern flank. This activity gradually ceased in late July, to be now replaced by the arrival of probably fresher and more gas-rich magma, hence more capable to produce explosions from the summit crater. The exclusion zone of 8 km radius around the volcano remains in place. It is extended to 12 km in the area of the Monte Grande valley to the south. [less]

After less than 3 days, the eruption already ended Sunday morning. The volcano observatory reported that tremor and lava effusion ceased abruptly at 11:15. However, a new eruptive phase in the near future cannot be ruled out. ...more
The access to the Enclos remains closed. Attached is a series of photos, taken on the first evening of the eruption by local resident Paul Dérand (thank you!).

The vertical cliff face of Palea Kameni's east side. Probably around 1457-58 AD, a part of the island broke off, exposing the concentrically fractured interior of the lava dome that forms the island which appeared in the caldera in 197 BC.

To address the huge challenge of navigating these sites on various platforms, Tom - as a distraction from the excessive heat during the past days here in in Athens - programmed a new menu, which hopefully should make it easier for you, dear visitor. To use it, just click or press on the 3-bar button right next to the logo. [less]

Volcano San Pedro at Atitlan Caldera Lake, view from Panajachel, Guatemala
These volcanoes are active in some way. Some have warnings and others are currently erupting. There are usually less than 10 volcanoes erupting simultaneously at any given time on the ring of fire. There are currently at least 36 erupting today and 32 more with warnings or minor activity. That is unprecedented. The bible refers to the sign of the last days as a woman in labor. When a woman's labor is coming to and end and the baby's head is crowning as it is born, they call that the ring of fire. Irony or God thinking ahead... You be the judge. As in Joel 2:30
  And I will shew wonders in the heavens, and in the earth, blood, fire, and pillars of smoke.
 the volcanoes are increasing in frequency and strength, like the birth pains of a woman. Jesus is coming people. Are you covered in the blood? God bless you and may Jesus keep you.
