If you’ve been watching the news about Japan this week, you may be thinking more about your personal emergency preparedness.

Hawaii’s Kilauea Volcano, at Hawaii Volcanoes National Park, is putting on a show right now, folks. On Saturday, its floor dropped about 377 feet, opening up a crack from which lava spewed 80 feet into the air (with true volcanic flair, I might add). Today’s not the day to go hiking or camping at the volcano: The fissure has expanded about a third of a mile, according to the Guardian, and there’s a threat of lethal sulfur dioxide in the air.

But …

You Asked: Why do volcanoes blow their tops? — Aittreya, Tamil Nadu, India Marshall Brain Answers: There are many different types of volcanoes. Some erupt gently over many years. Others cause huge explosions – they “blow their tops.” A great deal of the difference happens because of lava viscosity. When a volcano explodes, it happens […]

Unless you’ve been making like an extremophile and hiding at the bottom of a volcano lately, you would have been hard-pressed not to learn a little bit about the Eyjafjallajökull eruption this month. It’s continuing to raise a ruckus, according to the Iceland Meteorological Office. The agency reports that booming sounds were heard in Hvolsvöllur, which is about 20 miles (32 kilometers) west of the eruption site, this week.

Surprisingly though, the impressive geological phenomena had very little impact on public health, aside from keeping Europeans with respiratory conditions on higher alert than usual.

My father-in-law is a fan of the site and loves discussing article topics with me. A couple of months back, we wound up discussing methods of tinkering with the environment and brought up the ridiculous notion of setting off nuclear weapons to counter global warming. I blogged about this a while ago. Anyway, my father-in-law recommended another strategy: set off some volcanoes.

The Mars Odyssey spacecraft has discovered a curious sight on the red planet’s northern planes: mud volcanoes spurting methane gas and sediment up to the icy surface. Think about that for a second. What do you need to have mud? And what produces methane gas? That’s right, water and animals.

This is not to say the Martian underworld is overrun with jersey cows or giant sand worms. Animals aren’t the only source of methane, but scientists theorize that the gas could indeed be due to thriving microbes several miles beneath the Martian surface. Down there, warmer temperatures could theoretically permit things like mud and life to exist.

This news, reported in a New Scientist article, comes on the heels of a recent geological study on Earth supporting the notion that ancient, subterranean extremophiles might have survived the catastrophic celestial bombardment of the Earths’ crust 3.9 billion years ago.
