- It’s that time of year again – cast your ballot for the 2012 Pliny for Volcanic Event of the Year:
- How combining GPS sensors with seismometers can speed up identification of large/dangerous earthquakes, and emergency response.
- Very cool video of seismic waves from nearby earthquakes rippling across dense seismic array in CA.
- Rates of microseismicity on creeping part of Sand Andreas Fault waxes and wanes in synchrony with a neighbouring fault.
This story is part of the excellent AGU Fall Meeting coverage on their GeoSpace blog, featuring write-ups by a herd of science communication grad student. Good stuff.
- Want to know what GRAIL has discovered about Moon’s structure & geological history? Read Emily Lakdawalla’s brilliant post.
- GRAIL will apparently end with an eeeeeek-BOOM! Looking forward to seeing the final surface-skimming gravity data.
- A river of hydrocarbons flowing on Titan.
- Evidence for a key step in the evolution of photosynthetic organisms found in 2.4 billion year-old South African rocks.
- New Nature Geoscience paper suggests Permian extinction may have been a one-two (flood basalt-impact?) punch. Paleomagnetic data suggest that flood basalt eruptions are quite pulsed, but two extinction waves affecting different species=different causes?
- New Nature paper suggesting Ediacara are terrestrial lichens rather than enigmatic marine beasties. But hold on: Brian Switek explains that neither theory nor author are new.
- UK Environment Advisor’s talk on climate change, over at the Volcan01010 blog:
- Hard to really grasp scale of calving ice in this clip from Breaking Ice, up at the Guardian.

- Good article: River in retreat – Mississippi faces shipping freeze as water levels drop.
- Chicago River has become invasive species super highway – can it be blocked? and soon?
- BBC report suggests some faltering progress at Doha climate talks, but emphasis is on ‘faltering’.
- Good analysis at Earth Magazine by Michael Webber: near-term future of US natural gas production, consumption and prices.
- Is UK shale gas viable? Some good points here, but calling proponents ‘frack-heads’ hardly a cue for rational debate.
- Invasive cheatgrass fans US wildfires
- Mountains are geological sculptures: tectonics provides the blank stone block, but rivers & landslides do the carving. Good stuff from Metageologist.
- A very nice video demo of how smooth plate motions turn into jerky earthquake ruptures from GNS Science:
- It’s not just Mars: robotic rovers are helping explore the icy wastes of our own planet.
- Ionian Sea may be 220 Ma oceanic crust, oldest known. Note: based on magnetic anomaly modelling, not direct dating.
- Understanding the geological structure of the UK has just become easier: new 3D geology map resources from the British Geological Survey.
- Dave Petley has some spectacular images of a railway in W Canada completely buried under a rockslide:
- She wanted to study geology & was told, “You should be learning to cook.” That didn’t stop Dr. Ursula Marvin
- Why We Let the School Shootings Continue: ‘Children will continue to pay for a freedom their elders enjoy.’

- Nice summary by Liz Neely on some of the ways Twitter was used to enhance the AGU 2012 Fall Meeting experience:
- And as Top 10s go, this is a good one: Top 10 reasons to love the AGU conference (and yes, the free beer is mentioned).
- Oman is certainly different, although I found it a little more friendly than this writer did.
