Severe cooling from volcanic sulfates - not warming - was the primary trigger of a mass extinction event 201.6 million years ...

A second vent, immediately downslope of the first, erupted a pahoehoe lava flow that advanced to the northeast toward Hilo. By January 1881, the northeast flow was estimated to be about 18 miles ...

The mucky gunge resembled a certain type of lava referred to as ... It's just like pahoehoe, except that's molten rock. But again, it's a cooling skin that forms before hot material bursts ...

We called it getting our “lava legs.” But before long, strength and muscle memory overtook uncertainty, and we were jumping over crevasses 4 feet wide and 20 feet deep. Sections of pahoehoe—rippling ...

Centuries of eruptions on the Big Island have created hidden networks of passages beneath volcanoes. In December 2016 a large lava delta formed by Kilauea volcano sank into the sea, exposing the ...

Scientists have been observing this lava lake for decades. It sits over the magma reservoirs under Io's surface. The cooling lava at the center of the lake is ringed by possibly molten magma around ...

By the time the Hawaiian Volcano Observatory geologists arrived, the liquid lava had cooled enough to a solid but was still "hot to the touch," the US Geological Survey described in the YouTube ...

that formed in between eruptions and contain volcanic ash (left) that had been trapped between lava flows. They also located zircon within thick basalt flows where lava would have cooled more slowly.

“possibly starting with some unsuccessful wall-building in the Kukuau area of Hilo to control the advance of a Mauna Loa pahoehoe flow in 1881, and in Puna to control Kilauea lava flows in 1955 ...

One of the characteristics of lava stone countertops are small cracks or fissures on the glaze surface, often referred to as crazing. It’s produced during the cooling process after the slab has been ...

Water cooling systems appeal to people who push the envelope and build personal computers with the fastest chips, because water cooling is very efficient. They also eliminate large, noisy fans.

The Federal Reserve’s preferred inflation gauge showed price pressures cooled last month, rising 2.1% in September from a year earlier. The personal-consumption expenditures price index ...
