Geology field crews on the ground near the Kīlauea's fissure 8 midday on June 19, 2018 observed a still-vigorous channelized lava flow being fed by lava fountains at the vent. Standing waves are visible within the channel. Cascades/rapids are visible near the base of the cone, which is an estimated 50 m (164 ft) high. The maximum flow velocity in the channel is 7.7 m/s (17 mph). During the morning overflight, several small overflows could be seen along the channel margins. The flow of lava is more rapid in the center of the channel and decreases in speed toward the margins where friction with the channel walls increases. The lava flow forks as it nears the ocean, creating two ocean entry points.

PAHOA, HAWAII (HawaiiNewsNow) -In lower Puna, seven weeks after eruptions started, a bizarre new normal has set in.

The lava keeps coming, as vigorous as ever. Thousands of evacuees remain in limbo. And the devastation to homes and farms and neighborhoods grows.

On Thursday, fissure no. 8 — by far the most active so far — continued to create tall fountains of lava and was feeding a channelized flow headed toward the sea.

U.S. Geological Survey scientists said the channel was flowing at up to 17 mph in places and creating "rapids" at the base of a lava cone — now 164 feet high — that sits where there used to be homes and roads and yards in Leilani Estates.

Off Kapoho, lava continues to enter the sea, creating new land and plumes of laze — haze and shards of glass.

The delta off Kapoho has grown to a stunning 380 acres since Wednesday, according to officials, while Halemaumau Crater at Kilauea's summit has doubled in size since eruptions began in early May.

And three other fissures were also producing spatter, albeit not quite as profusely.

Another jarring sight: Lava "bergs" as big as vans can be seen in the rivers of lava.

Thomas Mason, who evacuated from his home in Leilani Estates with his wife, said the ongoing eruptions have everyone in "wait and see" mode.

The Masons moved from Maui in November and started building their retirement home on Kupono Street in February. They were just about ready for drywall when the first fissure opened up on Mohala Street on May 3.

Twenty-three additional fissures later, their home is now in an area that's been classified as uninhabitable. Although their house is unfinished, it's still standing. But it's completely inaccessible.

Like so many others, the Masons don't have insurance. And their situation underscores the complexities of a disaster whose end is nowhere in sight.

Since eruptions started May 3, at least 598 homes have been confirmed destroyed. Authorities fear the true figure is upwards of 700.

Geeze, the volume of stuff coming out from the Earth in that Hawaiian eruption is just amazing; and no sign of slowing down! I guess the Big Island is going to get a bit bigger.

Hawaiian Volcano Observatory reports that Fissure 8 continues to be very active and is feeding a lava channel to the ocean at Kapoho. The flow is expanding south along the shoreline. Gas emissions from the fissure eruption and laze at the ocean entry continue to be very high. Currently, there is no immediate threat, but persons near the active flow should be prepared and heed warnings from Civil Defense.
Due to frequent earthquakes, residents in the Volcano area are advised to monitor utility connections of gas, electricity, and water after earthquakes.

Ongoing eruptions have created more than 400 acres of new land on the Big Island
PAHOA, HAWAII (HawaiiNewsNow) Wednesday, June 27th 2018, 6:18 am CEDT Video's Pics
Meanwhile, officials also haven't been able to say how many of the destroyed homes were primary residences.
The eruptions started May 3, and U.S. Geological Survey scientists say lava now covers more than 6,100 acres on the Big Island and lava flowing off Kapoho has created at least 405 acres of new land.

The lava is also now flowing into an area offshore where the water is at least 200 feet deep.
And, scientists say, the lava flow front at the coast has broadened southward and is now nearly 2 miles wide.

During an overflight Tuesday morning, geologists observed lava entering on the southern portion of the flow front — primarily through the open channel.

And in lower Puna, fountains of lava from fissure no. 8 continue to build a spatter cone. It's now 180 feet tall at its highest point.
At Kilauea's summit, some 25 miles away, seismic activity also continues.

On Monday, a 5.3-magnitude quake rattled the summit following an explosion at Halemaumau Crater. It was the latest significant quake at the summit.

Unprecedented. Staggering. Profound. That's how scientists describe the last 2 months at Kilauea's summit

KILAUEA VOLCANO, BIG ISLAND (HawaiiNewsNow) - Hawaii Volcanoes National Park closed 49 days ago amid ongoing eruptions at Kilauea's summit. And in that time, the landscape of the park and at the summit have changed dramatically.

Hawaiian Volcano Observatory geologists estimate that Halemaumau Crater has doubled in size over the last two months and dropped a staggering 1,000 feet.

"This is a profound sequence of events here at Kilauea, unprecedented really in modern times," said Tina Neal, observatory scientist-in-charge.

Scientists say amid ongoing explosive eruptions at the summit, the amount of change that has taken place at Halemaumau is staggering. The crater’s volume has been increasing at a rate of more than 10 million cubic meters every day.

"Even after only one week has passed, the scale of change is really breathtaking," said Kyle Anderson, U.S. Geological Survey research geophysicist. "We’re used to looking at changes on the order of centimeters over years. Here the scale of change is tens of feet per day in some cases."

Special Report No. 3
The Reventador Volcano
Emission and fall of ash in the provinces of Pichincha and Napo
July 2, 2018
Today, July 2, 2018, a fall of fine white volcanic ash was reported in
the sector of Cayambe and in the town of Juan Montalvo. The ash comes from the volcano El
Reventador, which is in eruption since November 2002, with a characterized activity
emissions and continuous explosions since 2012. The internal and external activity of the volcano
keeps high, as in the previous days and weeks. The volcanic ash alert center
Washington VAAC reported a cloud of ash that reached 6.7 km high s.n.m. (3 km about
the level of the crater) today at 11h30 local time. This ash cloud is associated with a
explosion occurred at 11h16 local time (Figure 1). Due to the height of this emission,
together with the high speed (5-8 m / s) and the wind direction (west), the ash
reached the mentioned sector.
In case of being in an ash fall zone, it is recommended to take the measurements of
adequate caution. The IG-EPN maintains its surveillance and will report any change
significant in the activity of the volcano.

L’attività vulcanica della Terra sta aumentando? No, è tutto nella norma
13 luglio 2018:pinocchio:
Given the intense media coverage of recent eruptions, one may have the perception that global volcanic activity is increasing. There are many people who "social networks" ask if it is indeed so and if these events are related to each other. Another very frequent question concerns a hypothetical relationship between volcanic activity and earthquake activity on a world scale, in particular because the latter, in the current year, is - until now - lower than in previous years. There is no shortage of "do-it-yourself experts" and their numerous followers, who say that yes, volcanic activity is increasing, and that often do not hesitate to accuse "official scientists" of concealing or falsifying the truth.

In fact, all the information necessary to understand the meaning of the current volcanism on Earth is available on the net. To get a general idea of the volcanic activity trend over time, it is necessary to consult different sources, which are almost exclusively in English, and above all it is necessary to verify that they are reliable (Figure 2).

By consulting reliable sites, it turns out that the current volcanic activity is completely normal. At any moment around 20 volcanoes are in operation all over the world, some for many years, decades, or, like Stromboli, for centuries. Others awaken briefly and then return to a state of quiet, and still others enter a new period of activity that can go on for a more or less long time. Since they occur in remote and uninhabited areas of the planet, many of these eruptions do not enter the sphere of media interest and therefore the general public does not know about it. When, by chance, one or more eruptions have a strong and sudden impact on populated or tourist areas, the media attention becomes very high. Subsequently, on the long wave of the notoriety of the eruptions of strong media impact, other eruptions, often harmless but well observed, succeed for a certain period to make their appearance in the "mainstream media", precisely because at that moment there is a vivo public interest. However, if before there were no events with a strong impact, such as those of Kīlauea and the Volcán de Fuego, minor events would escape the attention of the media and therefore of the masses. In fact, during the first half of 2018 there were already more than 40 volcanoes in the world that recorded an eruptive activity. Very few of these have made headlines, partly because, fortunately, only a few eruptions have caused significant damage.

Looking at the data for the last two centuries (Figure 3), we note that the number of eruptions reported per year has increased after events of particular impact, both in terms of damage and human victims, and media, such as those of Krakatau in Indonesia (1883) and the Montagne Pelée in the Caribbean (1902), while during the two world wars, reports of eruptions have strongly decreased. The beginning of a systematic cataloging of active volcanoes (Catalog of Active Volcanoes of the World, CAVW, since 1955) and subsequently also the creation of regular publications on volcanic activity (Bulletin of Volcanic Eruptions, since 1960, and the reports of the Global Volcanism Project of the Smithsonian Institution, since 1975) have led to a clear increase in the number of reported eruptions, which however has eased in the 80s and 90s of the last century. Figure 3 shows, however, a further increase at the beginning of the current century, which can be ascribed to the advent of the Internet and the "social media", which allow an immediate and widespread dissemination of information, even by non- experts who have the opportunity to observe and document volcanic events, especially in remote areas, which otherwise would escape the attention of the scientific world.

The most significant datum contained in Figure 3 is, however, that on the major eruptions - events therefore with perceptible effects on more extensive areas and with a high probability of being noticed even in more remote regions. The reports of such events show a very regular trend in the last two centuries, showing that in reality volcanic activity is not at all increasing, but rather that it is our knowledge and our perception that have changed. Returning, then, to the current media attention caused by the eruptions of the Kilauea and the Volcan de Fuego, we can say that this is an attention designed to ease drastically as soon as the media will have other news to deal with, with the immediate consequence that the number of eruptions that will be noticed by the general public will come back down.

Another Volcano? Jupiter Probe Sees Hotspot on Roiling Moon Io (Photo)
Space.com Senior Writer | July 16, 2018 11:26am E
NASA's Jupiter-orbiting Juno spacecraft may have just boosted the already-impressive volcano tally on the gas giant's lava-spewing moon Io.

Juno's Jovian InfraRed Auroral Mapper instrument, or JIRAM, detected a sizable "hotspot" near Io's south pole on Dec. 16, 2017, during one of the probe's close Jupiter flybys. Juno was about 290,000 miles (470,000 kilometers) away from Io at the time, NASA officials said.

"The new Io hotspot JIRAM picked up is about 200 miles (300 kilometers) from the nearest previously mapped hotspot," Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome, said in a statement. [Amazing Photos: Jupiter's Volcanic Moon Io]

"We are not ruling out movement or modification of a previously discovered hotspot, but it is difficult to imagine one could travel such a distance and still be considered the same feature," Mura added.

Io is the most volcanically active body in the solar system, with its insides roiled and churned by Jupiter's powerful gravity and the tugs of its fellow Galilean satellites, Callisto, Ganymede and Europa. Thanks to the efforts of ground-based telescopes and NASA probes such as the Jupiter-orbiting Galileo and the Saturn-studying Cassini, astronomers have already mapped about 150 volcanoes on the moon, some of which blast lava 250 miles (400 km) out into space.

So, confirming a new Io volcano wouldn't come as much of a shock. Indeed, according to NASA officials, about 250 additional volcanoes likely await discovery on Io, which is the fourth-largest moon in the solar system. (With a diameter of about 2,260 miles, or 3,640 km, Io is slightly larger than Earth's moon.)

The $1.1 billion Juno mission arrived in orbit around Jupiter on July 4, 2016. The spacecraft loops around the gas giant on a highly elliptical path, making close flybys like the Dec. 16 encounter every 53 days. During these passes, Juno studies Jupiter's composition, structure, and gravitational and magnetic fields, looking for clues about the huge planet's formation and evolution (and also collecting a wealth of other data, as the Io observations show).
Juno's next close science flyby of Jupiter occurs today (July 16). The mission is scheduled to run through July 2021.
