Papua New Guinea's volatile Ulawun volcano erupted early on Tuesday, sending a column of red lava shooting up into the sky and forcing the evacuation of recently returned residents.

Mount Ulawun, situated on the remote Bismarck Archipelago chain, displaced between 7 000 and 13 000 people from their homes when it last erupted in June.

Seismic activity started at midday on Monday before the volcano erupted at about 04:30 on Tuesday, according to Rabaul Volcano Observatory assistant director Ima Itikarai.

"It was noiseless and in the dark just before dawn; the eruption was visible (with) a distinct shard (of) red incandescent glow shooting up less than 100m from the base," he told AFP.

One resident of Kagoshima was "completely covered with ash" after Japan's Sakurajima volcano erupted

Volcanic ash has rained down on a city after Japan's Sakurajima erupted and belched a massive column of ash two miles into the sky.

People in Kagoshima - five miles away from the volcano - posted photos on social media showing their ash-covered clothing or cars, and the particles falling in the streets.

One resident tweeted: "Sakurajima's ashes!!! Because I forgot my umbrella, I was completely covered with ash. The second photo is an ash-covered bag."

Sakurajima, of the most active volcanoes in the world, erupted at about 4pm local time.

Yellowstone's Steamboat Geyser breaks yearly eruption record

Steamboat geyser
Yellowstone National Park's Steamboat geyser is breaking records with 34 eruptions so far this year as of early September.

The famous attraction is the world's tallest active geyser and has broken its own record for the most eruptions set last year at 32, according to the National Park Service, and there's still months to go before the end of the year.

Steamboat's eruptions are unpredictable, the Park Service said, and over the years have been sporadic, with active years in 1982 - 1983 after being dormant for 50 years, quiet years throughout the 1990s and 2000s, and other years of dormancy marked by a single eruption.

"One thing is known, Steamboat Geyser's future eruptions will continue to be unpredictable, officials said on the Park Service's website.

Orange alert as Villarrica volcano rumbles in southern Chile

Villarrica in Chile

Villarrica in Chile
Rumbling at Villarrica, one of South America's most active volcanoes, has been worrying residents and prompted authorities to declare an orange alert this week.

Authorities in the south of Chile are rehearsing evacuation plans amid concern that the volcano could potentially erupt within "days or weeks."

Villarrica, near the popular tourist resort of Pucon around 750km south of the capital Santiago, was upgraded to an orange alert after it began rumbling and hurling lava into the air late on Tuesday.

The orange alert by the National Geology and Mining Service (SERNAGEOMIN) implies a "significant" increase in activity.

Ubinas volcano erupts
The most active volcano in Peru - Ubinas, erupted three times for a day. This happened yesterday, Wednesday, Sep 4. According to the local Institute of Geophysics, cited by AFP, the explosion produced an ash column that reached a height of about 2,500 meters above the top of the massif.

"Three new eruptions of the volcano have been registered, characterized by the disposal of solid and fine ash," Hernando Tavera, director of the Institute, told the agency.

Stromboli volcano in Italy erupts for 2nd time in a week

Stromboli volcano

Stromboli volcano
The Stromboli volcano, located on an island of the same name in the Tyrrhenian Sea in the south of Italy, had erupted for the second time this week.

Island residents said that around 10:45 p.m. (20:45 GMT) on Friday, a strong explosion was heard, after which the volcano spewed a column of ash and dust. Two smaller blasts were heard later on the same day.

Lava is actively flowing down the volcano's western slope. Witnesses say the lava can be seen several miles away from the volcano.

Adapt 2030 Ice Age Report: Fishy VEI-5 Shiveleuch eruption, too many excuses why it didn't happen

Shiveluch volcano eruption
VAAC and the US volcano monitoring agencies stepped back from a 70,000 ash ejecta call from the Shiveleuch Volcano down to 23,000 feet. Fishy that, because the Kamchatka Peninsula is one of the most watched areas on the planet with infrared to look for launches of tiny underground projectiles, but an eruption is so misjudged by 3X. Then spaceweather.com comes our for two days with an article explaining why sunsets are purple for two stratospheric level eruptions, but don't look at Shiveluch, its the other two. Finally the error was blamed on conversion from English to Metric height measurements, even though these Asian / US agencies have been working together for 50+ years, but get this one eruption wrong.

Winter is Coming Cycles of Change Presentation: A comprehensive PDF slide presentation with accompanying MP3 narration of the slides by David DuByne, author of Climate Revolution. Over an hour of detailed explanation and documentation of the rapidly approaching periods of life-changing cold we will soon experience and how it will reduce global crop yields leading to a prolonged economic contraction.

Climate Revolution: A 'Must Read' for understanding our Sun driven climate as we progress deeper into the new Eddy Grand Solar Minimum. Weather extremes leading to Global food scarcity and high food prices are here now, and this book describes the expected changes, how to survive & thrive during future challenging times with practical preparations.

Powerful volcanic eruptions are creating purple skies

Two major eruptions this summer have caused a stunning atmospheric reaction which have left the sunsets looking purple in certain quarters of the globe. The first of two eruptions came on July 22 when the Raikoke volcano, located in the Kuril Islands in Russia's Sakhalin Oblast region, erupted.

The volcano, which had remained dormant for more than a century before the latest explosion, blasted a mass of ash and volcanic debris ten miles into the sky, reaching a layer of the atmosphere known as the stratosphere.

Just under two weeks later, the Ulawun volcano in New Guinea erupted, sending ash nine miles into the sky and causing 15,000 people to evacuate.


Comment: Less than a week ago an eruption at Kamchatka volcano (Shiveluch) in Russia fired ash 70,000 ft (21.3 km) into the stratosphere.


Sulfuric gas from both of these eruptions reached the stratosphere, which is why skies in some parts of the world turned oddly purple as the Sun started to set.

This is because fine volcanic aerosols in the stratosphere cause blue light particles to scatter.

When the scattered blue particles combine with the normal red hue of a sunset, it makes an eerie purple glow.
