Hawaii gets new island as erupting volcanic crater continues to spew lava flow into sea

Lava flows that have been cascading into the sea have formed a brand new, small island off the coast of Hawaii after a crater at Mount Kilauea exploded with the force of a 5.2-magnitude earthquake.

Friday's crater explosion sparked a slow-moving flood of lava that destroyed hundreds of homes at Kapoho, on the Big Island. A once-scenic bay dotted with idyllic beach homes, parkland, and turquoise water used for swimming and scuba diving was quickly turned into a menacing, steaming dark pool. When the lava cooled, the sea peeled back to reveal a small island jutting out from the depths only a few meters from the mainland.

According to Hawaii News Now, the Hawaiian Volcano Observatory estimated that the island is about 20 to 30 feet in diameter. The new island formed at the northernmost part of the ocean entry and is "oozing lava similar to the lava oozing from the broad flow front along the coastline."

New tiny island of lava forms off Hawaii island

A tiny island of lava has formed north of the Kapoho ocean entry on Hawaii island.

During a Friday morning flight, a Hawaiian Volcano Observatory field crew noticed the new island oozing lava and producing a steam plume along the coastline.

HVO believes the new island could be part of the fissure 8 lava flow, which continues to flow into the ocean. It could also be a submarine tumulus that's created when slow-moving lava pushes the earth's outermost crust above sea level.

Small eruption occurs on uninhabited island south of Japan

A small eruption has been confirmed on an uninhabited island in the Pacific around 1,000 kilometers south of Tokyo, the weather agency said Thursday.

A Japan Coast Guard aircraft observed brown smoke coming out of a crater on Nishinoshima around 12:24 p.m., according to the Japan Meteorological Agency.

The island emerged in an eruption in 2013 but volcanic activity has slowed since August last year, prompting the agency to lower the alert level it issued for areas near the crater.

Given that land surface temperatures have remained steady, the agency believes the latest eruption did not lead to the release of lava.

Growing, deforming, shaking: Iceland's largest volcano Öræfajökull showing clear signs of unrest for last 18 months

Öræfajökull volcano in southeastern Iceland, the largest active volcano and the highest peak in Iceland, is showing clear signs of unrest with an inflation phase for at least a year and a half. The last eruptive episode of this volcano started in August 1727 and ended in May 1728.

The inflation is ongoing and is reflected by increased seismicity and characteristic deformation pattern, Icelandic Department of Civil Protection said July 13, after a series of meeting with scientists from The Icelandic Meteorological Office, The University of Iceland and Iceland Geosurvey.

There are no signs of a decrease in the inflation rate or the seismicity and the state of unrest persists despite a decrease in geothermal activity since last December.

The source causing the inflation is most likely injection of new magma, scientists said. The volume change since the start of the unrest is of the order of magnitude of 10 million m3 (about 0.2 m3/sec) comparable to the intrusion activity in Eyjafjallajökull some years before the eruption in 2010.


Comment: The eruption in 2010 grounded flights throughout Europe for nearly a week.


Comment: The uptick in volcanic and seismic activity all around the world point to much greater changes occurring:

Amazing photos show a BLUE volcano lighting up the skies of East Java, Indonesia

Remarkable images show dozens of tourists standing around to watch the spectacle in the western Indonesian province
Remarkable images show dozens of tourists standing around to watch the spectacle in the western Indonesian province
Jaw-dropping photos show a so-called 'blue volcano' lighting up the skies of Indonesia as mesmerised tourists watch on.

The incredible pictures show the Kawah Ijen volcano in East Java, Indonesia shooting 16-foot-high bright blue beams into the sky in a remarkable display.

According to experts the blue glow isn't actually from the lava, which is a similar colour to most other volcanoes, but from the gas emitted from the mountain.

Agung volcano in Bali explodes again sending rocks and flares of lava into the air

A volcano on the Indonesian holiday island of Bali erupted Monday, sending rocks and lava spewing into the air and unleashing a wave of panic across the island.

Residents reported hearing a loud explosion as Mount Agung flung volcanic rocks at least 2 km in the air. A sea of lava spewed from the crater, which ignited nearby vegetation.

Indonesia's National Agency for Disaster Countermeasure (BNPB) said the explosions began just after 9pm local time and that the ash column was seen as high as 2,000 meters above Mount Agung's peak.

Is there a connection between cosmic rays, earthquakes and volcanic eruptions?

cosmic rays
Scientists have detected a correlation between historic solar minima, volcanic activity, sun spots and climate change.

But taking the concept further, it does appear that cosmic impacts could trigger seismic activity causing earthquakes and volcanic eruptions.

John L Casey and his fellow authors examine the history of earth quakes during solar minimums in 'Upheaval!: Why Catastrophic Earthquakes Will Soon Strike the United States' (Casey, Choi,Tsunoda & Humlum (January 2017).
"The authors make a strong case for grand minimums being a causal factor in triggering these strong quakes."
Volcanic activity may be attributed to the increase in Galactic Cosmic Rays penetrating deep into silica rich volcanoes. Several studies have shown this correlation along with historical evidence.

Comment: Correlation clearly does not equal causation but there does appear to be a link with all these phenomena and the increasingly erratic behaviour of weather and geologic activity on our planet: Also check out SOTT radio's: Behind the Headlines: Earth changes in an electric universe: Is climate change really man-made?

After months of quiet, Mayon volcano in the Philippines erupts again

Following months of quiet, Mount Mayon erupted again on Sunday afternoon, July 1, sending white to light gray ash clouds 500 meters up the sky.

The eruption took place around 12:30 pm on Sunday. This was months after the Philippine Institute of Volcanology and Seismology (Phivolcs) lowered the volcano's alert level status from 3 to 2 in March.

Ed Laguerta, resident volcanologist of Phivolcs in Bicol, explained that Sunday's eruption was phreatic in nature.

A phreatic explosion is a steam-driven episode that occurs when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits.

Nearly 75,000 travelers have been stranded on the popular resort island after Mount Agung erupted. Volcanic ash can threaten aircraft by causing their engines to "flame out."

Thousands of travelers are stranded on the Indonesian resort island of Bali after a volcanic eruption forced authorities to shut down its main international airport in the early hours of Friday.

Nearly 450 flights have been canceled, affecting more than 75,000 passengers, and the airport will remain closed until 7 p.m. local time (1100 UTC), a spokesman for the disaster mitigation agency said. Airlines that have canceled flights include Air Asia, Jet Star, Qantas and Virgin.

Inconvenient facts about Antarctica's faux meltdown

Nearly all of the major news outlets last week ran attention-grabbing headlines uncritically reporting a supposed crisis of rapidly increasing melting of Antarctica. According to the reporting, accelerated melting of the continent's ice could raise sea level significantly and bring catastrophic coastal flooding to communities all over the world. If true, we should all be very alarmed about severe negative consequences to hundreds of millions of people.

This spate of Antarctic alarm was triggered by a study from an international team that measured ice volume and reported a dramatic increase in ice loss in recent years. This new study contradicts previous research which had consistently shown the continent steadily gaining ice volume since the beginning of the satellite era in the late 1970s.

NASA glaciologist Jay Zwally -- likely the pre-eminent expert on Antarctic ice accumulation and loss -- published a study in 2015 showing that ice loss in western Antarctica* and the Antarctic Peninsula was more than offset by significant accumulations in the rest of the continent. Both Zwally and the recent researchers were measuring the same thing, but the difference appears to be in the corrections made in adjusting for the movement of the Earth beneath the ice.
