Once a month or so, the geoblogosphere gets together to throw a blog carnival called the Accretionary Wedge. It's a fun bit of geological goodness, filled with excellent science writing all revolving around a common theme.
A probe sweeps through space. Roughly 4.5 million kilometers (2.6 million miles) away, you sit and watch images of another world appear. You notice a mottled surface, and on its horizon, jetting an incredible 260km (162mi) above its surface, a plume.
Right, we'll be back to Mount St. Helens soon, but we're going to take a few side trips first. Don't worry - it's all related. And there's a place in Oregon, not too far south of St.

The mountain boomed. Steam and ash soared to 3,962 meters (13,000 feet), announcing the end to a two-week lull. At the top of Shoestring Glacier, an opening steamed.
Thursday 26th July saw the launch of SciLogs.com, a new English language science blog network. SciLogs.com, the brand-new home for Nature Network bloggers, forms part of the SciLogs international collection of blogs which already exist in German, Spanish and Dutch.

There's more to an eruptive sequence than explosions. And there are times when a distinct lack of explosions are more troubling than endless ash columns.
What do you do when the volcano whose beauty you've admired for so long suddenly wakes with a shiver and blows a plume of steam and ash into the sky?
