Mapping Frontiers

The science of cartography has come a long way over the centuries, from the caricatured coastlines of antiquity to the highly-detailed satellite images of today. We know our terrestrial boundaries very well, and until all the polar ice melts and raises sea levels, mapmakers are busy looking elsewhere. Greg Laden explores the magma chamber beneath…

Back at the height of volcano-mania, I wrote that “Eyjafjallajökull’s ill temper been an unexpected object lesson in the complexity and interconnectedness of our environment, technology, and social networks.” Jason Goldman of The Thoughtful Animal added further dimensions in his post Intelligence, Cancer, and Eyjafjallajökull. But why stop there? Taking up that torch is Lee…

Though airplanes are starting to take off from various parts of continental Europe, UK airspace will remain locked down for at least another day. Eyjafjallajökull’s ill temper has been an unexpected object lesson in the complexity and interconnectedness of our environment, technology, and social networks. Who knew that you needed to factor glaciology and geophysics…

Generally, it takes the threat of imminent death or disaster to get earth science onto the front page of newspapers, and today is no exception. A massive plume of ash emanating from the tongue-twisting Eyjafjallajökull eruption in Iceland has thrown a wrench into much of Europe’s travel plans; the silicate particles in the ash can…

Volcanic Event of the Year

Erik Klemetti on Eruptions solicits your suggestions for the titular honor: 2009 is almost over and it has been quite a busy year, volcanically speaking. This is not to say that is was anomalously volcanic – more that many of the volcanic events captured the media’s attention. I’ll be putting together a “Volcanic Year in…

The Buzz: Step On a Crack…

When it comes to geologic phenomena, the difference between renewal and cataclysm can walk a fine line. On All of My Faults Are Stress Related, Kim Hannula elucidates the distinction between causes and triggers. Citing an article about the Zipingpu Dam that concludes that the weight of the reservoir might have triggered an earthquake, Hannula…

The Buzz: As the World Turns

As the Earth’s tectonic plates shift and grind miles below our feet, we feel the effects on the surface in the form of earthquakes and volcanic activity. As Ed Yong of Not Exactly Rocket Science and Chris Rowan of Highly Allochthonous explain, earthquakes far from tectonic plate boundaries may be aftershocks of more violent seismic…

The Buzz: Eruptive Media

This week, Eruptions’ Erik Klemetti sparked interest in the recent rumblings heard coming from Mt. Rainier in Washington State when he responded to a reader’s comment on increased seismic activity in the area over the past month. Klemetti’s response post, which reported on concrete facts surrounding the geologic events and featured a detailed graph of…
