Alaska Volcano

The team of explorers found the shiny golden orb when they were exploring an extinct volcano during the Seascape Alaska 5 expedition.

The eruption of the Hunga TongaHunga Ha'apai volcano was heard as far away as Alaska and shredded Tonga's undersea telecommunications cable.

Two new studies published in the journal Science have claimed the Tonga volcanic eruption to be the biggest explosion in last 140 years. It was comparable in terms of atmospheric intensity only to the Krakatau eruption, which took place in Indonesia in 1883. More than 30,000 people are believed to have died in that catastrophic event.

An Alaska volcano that has been rumbling since midsummer shot ash about 5 miles (8 km) into the sky on Sunday, triggering a warning to aviators and dusting one small fishing village, officials reported.

An Alaska volcano shot an ash cloud about 5 miles (8 km) into the sky on Tuesday, prompting flight delays and cancellations and raining volcanic particles onto at least one nearby community, officials said.

One of Alaska's most active volcanoes, a towering ice-covered cone in the Aleutian Islands, shot a cloud of ash more than 5 miles (8 km) high on Friday, triggering a warning to aviators and putting on a show that was captured in satellite imagery.

The Alaska Volcano Observatory has issued its highest level of alert for aviation after what it says was a brief eruption of a volcano on the Aleutian Islands on Tuesday.

Scientists raised the alert level for a remote Aleutian volcano on Monday after an explosion was detected on the mountain and heard by residents of a tiny village some 45 miles (72 km) away, a monitoring website said.

Strong winds on Monday pushed an ash cloud from an Alaska volcano into the heart of the state, grounding flights and limiting travel to western and northern communities off the road system.

Several US flights were canceled at two Mexican airports on Friday after ash from a nearby volcano fell in central Mexico, authorities said.

Alaska's Pavlof Volcano sent ash and steam skyward but not enough to raise the aviation threat for international air carriers.

One of Alaska's most restless volcanoes shot an ash cloud 15,000 feet (4,580 meters) into the air Friday in an ongoing eruption that is visible for miles.
