Deep, slow-slip action may direct largest earthquakes and their tsunamis
Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia -- Vancouver Island, Canada, to northern California -- are some of the most severe natural disasters in the world. Now a team of geoscientists thinks the key to understanding some of these destructive events may lie in the deep, gradual slow-slip behaviors beneath the subduction zones. This information might help in planning for future earthquakes in the area. (2020-12-21)

New fault zone measurements could help us to understand subduction earthquake
University of Tsukuba researchers have conducted detailed structural analyses of a fault zone in central Japan to identify the specific conditions that lead to devastating earthquake. The seismic slip processes that were inferred based on the measurements may be applicable to other subduction zones, such as those below the oceans. The gathered data could be applied in future attempts to describe or model the subduction earthquakes that lead to ground shaking and tsunami risk. (2020-10-30)

Deep magma facilitates the movement of tectonic plates
A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists from the LGL-TPE (CNRS/ENS de Lyon/UCBL1) have recently discovered. Their new model takes into account not only the velocity of seismic waves but also the way in which they are attenuated by the medium they pass through. The velocity of tectonic plates near the surface is thus directly correlated with the quantity of magma present. (2020-10-21)

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view is too simplistic. Their results solve a key problem facing the geosciences - and raise some new questions. (2020-10-21)

Turbulent era sparked leap in human behavior, adaptability 320,000 years ago
The first analysis of a sedimentary drill core representing 1 million years of environmental history in the East African Rift Valley shows that at the same time early humans were abandoning old tools in favor of more sophisticated technology and broadening their trade, their landscape was experiencing frequent fluctuations in vegetation and water supply that made resources less reliably available. The findings suggest that instability in their landscape was a key driver of human adaptability. (2020-10-21)

How rain can move mountains
Scientists have long thought that rainfall has a dramatic effect on the evolution of mountainous landscapes, but the reasons for how and why have been elusive. This seemingly logical concept has never been quantitatively demonstrated until now, thanks to a new technique that captures precisely how even the mightiest of mountain ranges -- the Himalaya -- bends to the will of raindrops.

Making bones is less difficult than was previously thought
The way in which bone formation occurs needs to be redefined. This was revealed by Radboud university medical center researchers and their colleagues in a publication in Nature Communications. It turns out that bone formation does not require complex biomolecules in collagen at all. This means that the production of bone substitutes and biomaterials is less complicated than was previously thought. (2020-10-08)

Magnetic field with the edge!
This study overturns a dominant six-decade old notion that the giant magnetic field in a high intensity laser produced plasma evolves from the nanometre scale. Instead the field actually originates at macroscopic scales defined by the boundaries of the electron beam that is propagating in the plasma. This could alter our understanding of magnetic fields in astrophysics and laser fusion and may help in designing next generation high energy particle sources for imaging and therapies. (2020-09-14)
