New study explains how continents leave their roots behind

In some areas of the seafloor, a tectonic mystery lies buried deep underground. The ocean floor contains some of the newest rock on Earth, but underneath these young oceanic plates are large swatches of much older continents that have been dislocated from their continental plates and overtaken by the younger, denser oceanic plate. Researchers have been puzzled by this phenomenon for some time: how does a continental plate leave some of itself behind?

Sol 1830: We’ve got the power

With apologies to Montgomery Scott, ‘we do not have the power…,’ but we will, as today was about keeping our state of charge up in preparation for possible CheMin activities in a near-future plan.

Sol 1815 – 1816: Stopping to Smell the Rocks

Planning for Curiosity this morning was a bit like reading a great mystery novel. There were several twists and turns along the way…

Sols 1811-1814: Mars of Many Colors

The focus of the weekend plan fro Curiosity was on carefully documenting the changes in stratigraphy as we leave the Murray bedrock. Fortunately, we are privy to a bevy of interesting targets and contrasting colors.

Computer earthquake prediction in lab shows promise

By listening to the acoustic signal emitted by a laboratory-created earthquake, a computer science approach using machine learning can predict the time remaining before the fault fails. Not only does the work have potential significance to earthquake forecasting, but the approach is far-reaching, applicable to potentially all failure scenarios, including avalanches and other events.

The science before (and during) the storm – Part 2

Caught in the Storm By Robert Emberson Sampling landslides in the field varies in difficulty; some are high up on hillslopes or in the headwaters of steep catchments, while others tumble into easily accessed river valleys. When planning for such sampling, we had mainly anticipated that the weather would not be the biggest obstacle, but that’s what transpired for a major portion of our fieldwork in central Taiwan. The typical …
