You Say it's Winter Already? Fall Has Just Arrived in California!

Some people say they could never live in California. The earthquakes are scary and the state will fall into the sea. The politics are too crazy. It's an urban hell. Californians are too flaky. Pick you reason. But there are things that are undeniably nice about California. Our fall season is one of them. Oh, it's true that my fair state can hardly compete with the extravaganza of

Geosciences Column: Earthquakes and depleted gas reservoirs; what comes first?

An ever growing population means the requirement for resources to fuel our modern lifestyles grows too. Be it in mining, oil/gas extraction or the improvement of renewable technologies, the boundaries of where and how we access resources are constantly being pushed. Previously inaccessible resources become viable prospects as demand increases and our technological know-how advances. Hand in hand with technological advances, comes an increased awareness of the environment and how it may be [...]

Every once in a while I need some justification for continuing my rants on earthquakes and other things.  After all, it is tough go against the Winds of Indifference by the Big Guys.  Oklahoma is going to destroy all US oil production and nobody cares.  The Bruce Deep Hole is sinking a shaft on top of a giant fault and everybody ignores it.

In a new paper, we examine the distribution of landslides from two earthquakes in New Zealand to see if hillslope preconditioning - the idea that the legacy of one trigger event can influence slope behaviour ins subsequent event - occurred. The results suggest that this might have been a factor in the area affected by both

A very popular activity in October was 'Shaken but not stirred; how earthquakes affect buildings.' This is a teacher-led demonstration of the relationship between the frequency of the shaking of the ‘ground’ and the movement of model ‘buildings’ of various heights. The activity can be used to help students to explore the effects of earthquakes in densely populated areas, and to

An earthquake felt round the world. Research shows that large earthquakes may trigger smaller earthquakes thousands of miles away. On April 11, 2012, an 8.6 magnitude earthquake in the Indian Ocean shook the Sumatran coast. Only a day later—3,900 miles (6,230 km) away—seismologists detected a set of smaller temblors rattling the eastern coast of
