The seismologists and official had been on trial for not adequately warning the public about the danger of a potential earthquake prior to the L'Aquila earthquake in April 2009 that killed 309 people.

Hazardous Living: Watching Curiosity land safely was exhilarating

Sometimes humanity accomplishes something absolutely awesome. Tonight was one of those nights. We put another rover on Mars — by far the most advanced rover yet. Curiosity is now out exploring Gale Crater and much is expected of her.

Blogging on EARTH: Curious to watch Curiosity land on Mars?

Sunday night will bring excitement to households around the world, not only because of the Olympics (and the GEOlympics), but also because the Mars Science Laboratory, also known as the Curiosity rover, will touch down on the Red Planet.

Blogging on EARTH: Finding prehistoric souvenirs in Michigan

Around the Fourth of July, I usually visit my parents and participate in a geological family tradition that is pointless to the extreme and yet addictive and fun. Mom and Dad live on Lake Leelanau near Traverse City, Mich. The lake is about a dozen kilometers long and a few kilometers wide. It’s a great place for water-skiing, fishing, jet-skiing and kayaking.

Blogging on EARTH: Rarity the only reason for Venus transit fever?

If you read one or more stories leading up to yesterday’s transit of Venus across the face of the sun (or if you followed #VenusTransit on Twitter), you likely learned that the transit is akin to a solar eclipse — when the moon crosses directly between Earth and the sun, temporarily blocking part or all of the latter from our view — with the caveat that Venus only blacks out a small dot of the sun because of its distance from Earth. So what was all the fuss about? What was it about the celestial equivalent of watching a marble roll slowly across a dinner plate that brought people out in droves, from professional and amateur scientists to casual observers and families with young children?

Venus in transit to the transit

5 June 2012 - Reader Elizabeth Talley snapped an iPhone photo of an ice ring around the sun yesterday afternoon in Port Charlotte, Fla., and unexpectedly also captured this image of Venus as it heads toward this evening’s rare celestial event — a transit of the sun. The seven-hour transit, during which the planet will appear as a small black disk moving across the solar face, will begin at 6:03 p.m.

Policy in the field: What's next for tax policies and the American clean energy economy?

It takes green to be green. Renewable energy technology requires dedicated investments, whether public or private, to succeed. The costs are steep, but many consider the cause worthwhile. After all, politicians on both sides tout having diverse array of energy resources as important for national and economic security. Nonetheless, in this tight economic climate, very little is safe. Now, Congress is starting to look at federal tax policies as they affect renewable energy development.

Blogging On EARTH: Wisconsin's microquake mystery

On the list of earthquake-prone states, Wisconsin does not rank highly. Yes, occasionally, America’s Dairyland is subjected to light rumbles emanating from its neighbor to the south, Illinois. But Wisconsin is hardly where you’d expect to find much excitement, let alone fear, over the possibility of homegrown seismic activity. And yet, that's exactly what happened a few weeks ago, when hundreds of people in Clintonville, Wis. began dialing 911 with reports that their homes were being inexplicably shaken overnight by terrifying booms.

Blogging on EARTH: Congress considers severe weather policy options

It doesn’t take a geoscientist to know that severe weather impacts our lives. Tornadoes, hurricanes, windstorms, solar storms, droughts … the list goes on.
