Earthquakes in Napa, Iceland and…Ohio? [Video]

Photos are everywhere today of wine bottles, and in some cases wine barrels, broken on the floors of Napa Valley, the famous wine region in California–dashed to the ground by a magnitude 6.0 earthquake that struck there early Sunday. News outlets are also filing regular reports from Iceland, where thousands of small earthquakes have occurred [...]

Italy’s Mount Etna Erupts Again [VIDEO]

A decade after a series of eruptions forced evacuations from the flanks of Mount Etna in Sicily, the volcano is acting up again. This amazing video shows the new flows: Mount Etna is an enigmatic volcano. It doesn’t fall neatly into any of the three major categories of volcanoes—the quiet rift volcanoes that occur where [...]

Obama’s Indonesia trip may be cut short by deadly volcanic eruption

Gunung Merapi, Java

President Obama’s visit to Indonesia this week will reportedly be cut a few hours short due to an ash plume from a volcanic eruption in the country. The eruption of Mount Merapi, more than 400 kilometers from Jakarta, where Obama is visiting, has killed more than 150 people since it began erupting in late October, [...]

All-out geoengineering still would not stop sea level rise

p>Mimicking volcanoes by throwing particles high into the sky. Maintaining a floating armada of mirrors in space. Burning plant and other organic waste to make charcoal and burying it—or burning it as fuel and burying the CO2 emissions. Even replanting trees. All have been mooted as potential methods of “geoengineering“—”deliberate large-scale manipulation of the planetary [...]

Is the cure (geoengineering) worse than the disease (global warming)?

mount-pinatubo

If there’s one thing more potentially contentious than the international politics of global warming (which the world has spent at least the past 20-plus years dithering about), it’s the politics of the most radical suggestion to solve it: geoengineering. After all, he who controls Earth’s thermostat may well control Earth. And what’s good for one [...]

Lasers and LiDAR systems gather data about the position and makeup of Iceland’s volcanic plumes

Eyjafjallajökull, Iceland, volcano, weather

With Europe’s airport staffers scrambling to send tens of thousands of flights into the air to make up for a week’s worth of halted traffic and stranded travelers thanks to Iceland’s Eyjafjallajökull volcano, researchers at the U.K.’s University of Reading are taking the first direct measurements of the ash plume parked over Scotland. The researchers [...]

Volcanoes killed with global warming, 200 million years ago

north-american-basalt

When Pangaea finally broke up, some 200 million years ago, the result was a lot of heat. Specifically, volcanism, as enormous flows of basalt burst to the surface, ultimately covering more than nine million square kilometers. It wasn’t just the death of a supercontinent; it was also one of Earth’s five major extinction events—and the [...]
