Researchers returning from a cruise some 250 miles off the coast of Oregon have reported seeing a volcanic eruption on the seafloor that they accurately forecast five years ago—the first successful prediction of an undersea eruption. The event took place at Axial Seamount, one of the most active and intensely studied undersea peaks in the world.

Northern New Jersey, southern Connecticut and environs are not necessarily where one would expect to explore the onetime extinction of much life on earth, and subsequent rise of dinosaurs. But it turns out to be a pretty good place to start. Underlying the exurbs are geological formations left by three giant episodes of volcanism starting around 200 million years ago, and intervening layers of sediments that built up in the interims between massive lava flows.

Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended “volcanic winters” from gigantic blowups helped kill off dinosaurs and Neanderthals...

Scientists are in the early stages of building a fiber optic network on the seafloor for observing, in real time, deep-sea hydrothermal vents---places where super-heated water and minerals spew from Earth's crust offering clues about how life on the planet may have began.

But Global Warming May Have Helped Override Some Recent Eruptions
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics—but suggest that such effects may have been masked in the 20th century by rising global temperatures
