Activity at Mount Etna spreading to all craters, Italy

Following an increase in Strombolian activity on February 27, 2017, Mount Etna, Europe’s largest volcano, continues erupting and it appears the activity is now spreading to all the craters at the top of the mountain. INGV reported that Strombolian activity at Etna’s New Southeast Crater (NSEC) cone had gradually intensified beginning at 16:00 UTC on February 27. Lava soon overflowed the vent, quickly traveled down the S flank, and then slowed after reaching the gently sloping terrain. The flow spread SSW, towards the old cone of Monte Frumento Supino. Frequent Strombolian explosions ejected incandescent lava fragments up to 200 m (656 feet)...

3-hour volcanic eruption in Alaska threatens villages with ash

An Alaskan volcano experienced its largest eruption to date and created a large ash cloud. For the past several months, Bogoslof Volcano has had minor eruptions, but the most recent was its strongest, sending ashes 35,000 feet above sea level. Residents of the Aleutian Islands are under ash advisory after Bogoslof Island’s volcano had its strongest recorded eruption Tuesday night. The National Weather Service warned that the fishing communities could see a trace amount of ash following the powerful eruption. This isn’t the first time the volcano has erupted. Tuesday was the 36th recorded eruption over the last three...

Major earthquake ‘Certain’ to hit Southern California

It is simply a matter of time before a major earthquake hits Southern California, according to a new study by the US Geological Survey (USGS), which examined patterns of historic quakes. The only question is how long it will be before the ‘Big One’ strikes. The study – the most extensive of its kind – examined a section of the San Andreas fault that runs along Interstate 5, near Frazier Mountain in northeast Kern County. “One of the reasons why this location is of importance is because in Southern California, the Big Bend, Carrizo, and Mojave sections of the...

2 Studies Show 347 Native Bee Species ‘Spiraling Toward Extinction’

Having taken a backseat to any number of controversies surrounding the nascent Trump administration, pollinators should be back in the headlines — again painting a tragic portent for the future of the planet’s food supply — as an analysis found 347 bee species native to North America and Hawai`i “are spiraling toward extinction.” In total, 700 bee species have been pushed to precarious footing by a web of threats, including increased pesticide use and severe habitat loss. In “Pollinators in Peril: A systematic status review of North American and Hawaiian native bees,” the Center for Biological Diversity studied 4,337...

Oroville Dam faces another risk: Earthquakes from rapid rise in water levels

The crisis over the last few weeks at Oroville Dam was about how to handle large amounts of water flowing into the lake with both of the reservoir’s spillways damaged. But there also was a seismic angle to the story. As Lake Oroville swung from being at 41% of capacity to 101% in just two months, scientists are asking whether the filling of the reservoir at the fastest rate in at least a generation can produce a damaging earthquake. No one knows for certain, but the question has been a source of debate since shortly after the nation’s tallest...
