LONDON (AP) — Residents of a fishing town in southwestern Iceland left their homes Saturday after increasing concern about a potential volcanic eruption caused civil defense authorities to declare a state of emergency in the region. The town of 3,400 is on the Reykjanes Peninsula, about 50 kilometers (31 miles) southwest of the capital, Reykjavik. Authorities also raised their aviation alert to orange, indicating an increased risk of a volcanic eruption. Concern about a possible eruption increased in the early hours of Thursday when a magnitude 4.8 earthquake hit the area, forcing the internationally known Blue Lagoon geothermal resort to close temporarily. The magma corridor is about 10 kilometers (6.2 miles) long and spreading, he said.

CNN —Iceland has declared a state of emergency, with police officials urging residents to evacuate the coastal town of Grindavík following an intense wave of earthquakes in the southwest of the country linked to a possible volcanic eruption. In statements Friday, Iceland’s Civil Protection Agency said a magma tunnel that is forming could reach Grindavík. Its progress is being closely monitored,” the Civil Protection Agency said. But we also want to reiterate that this is not an emergency evacuation, there is plenty of time to prepare, secure things and drive out of town calmly,” the Civil Protection Agency said. We faced that together, we will face this together and we will not lose heart,” the Civil Protection Agency added.

An ongoing volcanic eruption has created a tiny island near Iwoto. AdvertisementAdvertisementJapan has a new tiny island thanks to an ongoing eruption from an underwater volcano. The 328-foot-wide island emerged in the Ogasawara Island chain, about half a mile from Iwoto (formerly known as Iwo Jima). Those who want to marvel at the rare sight should do so quickly, as the island may not last very long, Usui told the AP. Similar volcanic islands appeared in the area in 1904, 1914, and 1986 but have all since been washed away, said Fukashi Maeno, an associate professor at Tokyo University's earthquake research institute, per The Guardian.

HUSAVIK, Iceland (AP) — The Blue Lagoon geothermal spa — one of Iceland’s biggest tourist attractions — closed temporarily as a swarm of earthquakes put the island nation’s most populated region on alert for a possible volcanic eruption. “People thought a volcanic eruption was about to happen.”The area around Mount Thorbjorn on the Reykjanes Peninsula has been shaken by hundreds of small earthquakes every day for more than two weeks due to a buildup of volcanic magma some 5 kilometers (3.1 miles) underground. The Reykjanes Peninsula on Iceland’s southwestern coast is includes a volcanic system that has erupted three times since 2021, after being dormant for 800 years. At Grindavík, a fishing town of 3,400 people, residents have experienced a series of seismic episodes since the Reykjanes Peninsula began to rumble three years ago.

The most dangerous volcanic threat in Italy right now is one you’ve probably never heard of: Campi Flegrei, or the Phlegraean Fields. The last major eruption of Campi Flegrei was in 1538, and it created a new mountain in the bay. So far in 2023 Campi Flegrei has recorded more than 3,450 earthquakes, 1,118 of which occurred in August alone. There are two hypotheses as to what could be causing the current increase in seismic activity at Campi Flegrei, according to De Natale. Vesuvius and the Campi Flegrei area.

Tokyo CNN —The world’s newest island has risen from the sea off the coast of the Japanese island of Iwo Jima in the Pacific Ocean. Japan’s Meteorological Agency (JMA) told CNN the unnamed island was formed by an undersea volcanic eruption. The photos show a small eruption sending a dark cloud of ash above the tiny island, which is now part of the Ogasawara Island chain. The island sits about 1,200 kilometers (750 miles) south of mainland Japan and a kilometer from Iwo Jima, the island that saw some of the fiercest battles of World War II in the Pacific. US Marines fought tens of thousands of Japanese garrisoned there in a battle that killed more than 7,000 Americans and 22,000 Japanese troops.

The theory, called the giant-impact hypothesis, explains many fundamental features of the moon and Earth. And many scientists assumed any debris Theia left behind on Earth was blended in the fiery cauldron of our planet’s interior. They were already aware that there are two massive, distinct blobs that are embedded deep within the Earth. That’s when he learned new details about Theia, the mysterious projectile that presumably struck Earth billions of years ago. And, as a trained geophysicist, he knew of those mysterious blobs hidden in Earth’s mantle.

This alien planet, Theia, was thought to have completely disappeared in the collision. AdvertisementAdvertisementAs well as shedding new light on the inner workings of our planet, scientists hope they will one day have access to these slabs of alien rock to reveal, once and for all, how our moon formed. The assumption has long been that Theia melded into moon, the Earth's mantle, and its core, in effect disappearing completely. Previous theories have suggested this core-mantle boundary could be made up of bits of ancient ocean floors. The problem is that the core-mantle boundary is very far from the surface — about 1,800 miles.

They wanted to investigate the rocks that may contain insights about the contents locked within Earth’s core and mantle, the mostly solid layer of Earth’s interior located beneath its surface. Helium inherited from the solar nebula likely became locked in Earth’s core as the planet formed, making the core a reservoir of noble gases. “So, the helium we measured in these rocks would have escaped the core perhaps 100 million years ago or possibly much earlier.”Helium leaking from Earth’s core doesn’t affect our planet or have any negative implications, he said. If so, have fluxes of these elements from the core over (Earth’s) history influenced planetary evolution? I am excited to investigate links between helium and other light elements,” Horton said.

ROME, Oct 5 (Reuters) - The Italian government is planning for a possible mass evacuation of tens of thousands of people who live around the Campi Flegrei super volcano near Naples, officials said on Thursday. The caldera is dotted with 24 craters and is a much bigger volcano than the nearby Vesuvius, which destroyed the ancient Roman city of Pompeii in 79 AD. Civil Protection Minister Nello Musumeci said this week evacuations would only be triggered in case of "extreme necessity". One of its biggest eruptions took place 39,000 years ago and might have led to the extinction of Neanderthal man, researchers say.

ROME, Sept 27 (Reuters) - A leading volcanologist has warned that mass evacuations might be needed in a town close to Naples, which sits on a so-called Super Volcano that has been hit by hundreds of small earthquakes in recent weeks. Campi Flegrei sits across the bay of Naples from Pompeii, where thousands were incinerated by Mount Vesuvius in 79 AD. However, it is a much bigger volcano than Vesuvius and if it ever exploded at full force could kill millions. Speaking in a personal capacity, De Natale said the last time Campi Flegrei suffered a similar burst of earthquakes in the 1980s, some 40,000 people were temporarily evacuated from nearby Pozzuoli. The Campi Flegrei caldera has a diameter of about 12-15 km (7.5-9.3 miles) and last erupted in 1538.

☆ New research may offer clue in search for rare pink diamonds
▼ + stars: | 2023-09-19 | by ( Katie Hunt | ) edition.cnn.com time to read: +4 min

CNN —Pink diamonds are extremely rare and coveted — a now-closed mine in Australia has been the source of 90% of the colored gemstones. The Argyle diamond mine is located in the remote Kimberley region in the far northeast of Western Australia. At Argyle, this process occurred around 1.8 billion years ago when Western Australia and Northern Australia collided, turning the once-colorless diamonds pink hundreds of miles below Earth’s crust. Pink diamonds from the Argyle diamond mine were formed when an ancient supercontinent was breaking up into fragments, according to a new study. This chain of events, according to the study, suggested that the junctures of ancient continents may be important for finding pink diamonds — and may guide exploration for other deposits.

Kilauea, Hawaii’s most active volcano, erupted for the second time in three months on Sunday afternoon, according to the Hawaiian Volcano Observatory, which said there was no immediate danger to residents. The observatory raised alert levels for Kilauea to a warning from a watch just under an hour before the eruption began. Livestreamed footage showed fissures at the base of the volcano’s main crater, Halemaʻumaʻu, generating lava flows on its surface floor. Kilauea, in Hawaii Volcanoes National Park on Hawaii’s Big Island, last erupted in June, and the observatory had been closely monitoring it for another possible eruption since August. Increasingly frequent earthquakes, swelling of ground during the past few weeks and pools of magma flowing upward over the past 24 hours were all signs of an imminent eruption, according to the observatory.

These eruptions have baffled scientists as they happen more often after continents break up. "The pattern of diamond eruptions is cyclical, mimicking the rhythm of the supercontinents, which assemble and break up in a repeated pattern over time," Gernon said. In fact, scientists found that most kimberlite volcanoes occurred 20 to 30 million years after the tectonic breakup of Earth's continents. But instead, it tends to appear in "a sweet spot in the interior of continents where diamonds form," Gernon said.

In the test, Fervo drilled down drilled down to 7,700 feet and then turned to drill another 3,250 feet horizontally, and internal temperatures reached roughly 375 degrees Fahrenheit. In the United States, geothermal energy supplies only 0.4% of electricity right now. Instead of relying on naturally occurring conditions, Fervo is using drilling technology developed by the oil and gas industry with hydraulic fracturing to create reservoirs in rocks deep underground. "By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world," Tim Latimer, the CEO of Fervo Energy, said in a written statement.
