A tale of two lovers, Popocatepetl and Iztaccihuatl by Amber L. Madden-Nadeau
Popocatepetl – more colloquially known as “Popo” – means “smoking mountain” and is an active volcano just 60 km from Mexico City (Figure 1) with 20 million people living within this catchment area. It stands right next to Iztaccihuatl or “Izta”, an extinct volcano with multiple peaks. Iztaccihuatl means “white woman”, with many believing that this volcano looks like a sleeping woman. At 5636m and 5230m, Popo and Izta are the second and third highest peaks in Mexico, respectively.

Eruption update 07:40 UTC : Seismic and infrasound signals indicate that this event was very similar to the event from earlier today at 14:30 UTC. The duration of the event was less than 2 minutes, and seismicity and infrasound returned to low levels following the explosion. A small steam-rich volcanic cloud is visible in satellite data, rising no more than 10,000 ft asl.

Pavlov volcano, Alaska, USA
Increase in alert status van green to yellow
Update 23:21 UTC: Volcanic Activity Summary: Over the past several days, there has been an increase in low-frequency earthquake activity at Pavlof. Such increases are sometimes seen prior to eruptive episodes, however in other cases they decline without eruptive activity. In addition, several short duration tremor-bursts have been observed today, and AVO received a pilot report of a possible ash cloud this afternoon. Infrasound data from local instruments on Pavlof and from a more distant network in Sand Point do not show any evidence of significant explosive activity. Precursory activity prior to eruptions of Pavlof are always very subtle, thus, on the basis of these observations we are increasing the Aviation Color Code to Yellow and the Alert Level to Advisory.
Remarks: Pavlof Volcano is a snow- and ice-covered stratovolcano located on the southwestern end of the Alaska Peninsula about 953 km (592 mi) southwest of Anchorage. The volcano is about 7 km (4.4 mi) in diameter and has active vents on the north and east sides close to the summit. With over 40 historic eruptions, it is one of the most consistently active volcanoes in the Aleutian arc. Eruptive activity is generally characterized by sporadic Strombolian lava fountaining continuing for a several-month period. Ash plumes as high as 49,000 ft ASL have been generated by past eruptions of Pavlof, and during the March 2016 eruption, ash plumes as high as 40,000 feet above sea level were generated and the ash was tracked in satellite data as distant as eastern Canada. The nearest community, Cold Bay, is located 60 km (37 miles) to the southwest of Pavlof.

Science - A drone boat to Investigate Acidic Crater Lakes
A novel aquatic drone ventured into highly acidic waters to test the feasibility of remotely exploring and surveying hazardous volcanic lakes.
In 1986, Lake Nyos in Cameroon exploded, jetting water more than 100 meters into the air as roughly 1.2 cubic kilometers of carbon dioxide suddenly belched from the waters. This enormous wave of gas smothered the surrounding countryside, killing more than 1700 people.
The deadly eruption focused attention on the dangers posed by active volcanic crater lakes and the importance of monitoring such lakes for changes in volume and other factors. About 35 such lakes dot the Earth, but monitoring active volcanic lakes can be problematic, especially when they undergo frequent eruptions of steam and other gases. These eruptions can make them too dangerous for human inspection by inflatable boat or raft.
However, the recent burgeoning interest in autonomous aerial drones presents researchers with an opportunity. So we asked ourselves, Could a small, inexpensive, and easily transportable autonomous boat, equipped with sonar, do the job? Read the full article here

Bogoslov volcano, Alaska, USA
Eruption update 15:21 UTC: A short duration explosive event occurred at Bogoslof volcano at 14:30 UTC on June 7 (6:30 am AKDT). Seismic signals indicate that this event was slightly larger than a similar explosion detected at Bogoslof yesterday morning The duration of the event was about 2 minutes, and seismicity returned to low levels following the explosion. No volcanic cloud has been seen in satellite data as of 14:30 UTC. Due to the brevity of the event, the Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH.

Bogoslov volcano, Alaska, USA
Update 08:02 UTC: Low amplitude seismic tremor from Bogoslof Volcano was detected in seismic data beginning at about 20:29, June 5 UTC (12:29 AKST) and has since decreased to background levels. A USF&WS vessel in the vicinity reported vigorous steaming and a "white plume" rising several thousand feet above sea level. This cloud was too small to be observed in satellite images. Earlier today, a short duration explosive event occurred at Bogoslof (15:50 UTC, June 5) and produced a small volcanic cloud that was observed by a pilot. These events are near the lower level of detection threshold based on current monitoring capabilities and reinforce the hazard that continues to exist in the vicinity of Bogolsof volcano

Update 16:46 UTC: A short duration explosive event occurred at Bogoslof volcano at 15:50 UTC on June 5 (7:50 am AKDT) and produced a small volcanic cloud that was observed by a pilot. Winds are transporting the cloud towards the south at an estimated altitude of 20,000 ft asl. The duration of the event was less than 2 minutes, and seismicity returned to low levels following the explosion.
Due to the brevity of the event, the Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH.

Mount St Helens, USA (Philippa)
Historic image of the day (via @USGSVolcanoes): scientists collecting samples of pumice following the 1980 eruption of Mount St Helens.

Pumice is a glassy, vesiculated (i.e. filled with holes) form of lava, which is so light that it can float on water. It is the volcanic equivalent of the foam from a newly-opened champagne bottle, i.e. the gas-rich froth formed at the top of a magma-filled conduit just prior to and at the start of an explosive eruption.

Collecting samples, like in this photo, and using powerful microscopes to analyse the size and shape of the holes in the pumice provides clues from previous eruptions that will help us to better understand conditions in volcanic conduits prior to future eruptions.

Kilauea volcano, Hawaii, USA (Philippa)
Capturing fresh samples of lava on a weekly basis for geo-chemical analysis in the lab is just one of the many ways that scientists at the US Geological Surveys (USGS) Hawaiian Volcano Observatory (HVO) monitor changes in the continuing eruptive behaviour at Kilauea volcano. The lava sample has to be quenched immediately in water in order to try and preserve its eruptive chemical composition as best as possible. What cannot be appreciated from this video is the prickly feeling on skin of the immense heat and the eye-wateringly pungent smell of the gases (fluorines and chlorines) being emitted by this lava.

Using Film to Reduce Risk on Volcanoes
by Holly Davison (and Anna Hicks)
For people to cope with environmental hazards, they need to understand threats – a key step that can lead to behavior change. A recent paper by Anna Hicks et al., published in the International Journal for Disaster Risk Reduction, describes the importance of communicating glacier hazards and other risks. The authors made videos and then assessed their effectiveness for risk communication in volcanically-active communities. The films were used to communicate findings from the Strengthening Resilience in Volcanic Areas (STREVA1) project, led by the University of East Anglia in the UK, in order to apply effective volcanic risk assessments.

Poas | Costa Rica
OVSICORI-UNA reported that tremor amplitude at Poás fluctuated between low and high levels during 23-30 May, often corresponding to the vigor of emissions of water vapor, magmatic gases, and material from fumarolic vents. During 25-26 May ashfall was reported in some communities around the volcano. Low magnitude volcano-tectonic earthquakes and small phreatic eruptions were recorded sporadically during 27-30 May.

Rincon de la Vieja | Costa Rica
OVSICORI-UNA reported that a small hydrothermal explosion occurred at 1020 on 23 May in Rincón de la Vieja's crater lake, producing a small lahar that traveled down the N flank of the crater.

Sheveluch | Central Kamchatka (Russia)
KVERT reported that during 23-25 May powerful explosions at Sheveluch generated ash plumes that rose 8 km (26,200 ft) a.s.l. and drifted 715 km in different directions. At 0830 on 25 May explosions generated ash plumes that rose 9-10 km (29,500-32,800 ft) a.s.l. and drifted 16 km NE. The Aviation Color Code (ACC) was raised to Red (the highest color on a four-color scale). Around 30 minutes later the ash plume was identified in satellite images drifting 45 km ENE. Strong steam-and-gas emissions rose from the lava dome. The ACC was lowered to Orange. Within the next hour the ash plume drifted 82 km E.

The phenomena can be compared with liquefaction as shallow underground layers are getting liquid by the strong shaking. When the pressure builds up, the mud tries to find an exit and the Pakistan coast seems to be the ideal environment to produce these strange beauties. Often they disappear in only a couple of days or weeks. The biggest ones are, for the time they exists, the most talked about excursion for tourists.
