One of the challenges for assessing earthquake hazards in the Caribbean is that most of the tectonic plate is below sea level and "we can only access the active faults where they are exposed on the islands,” she adds. This is in sharp contrast with the San Andreas Fault in California, where monitoring equipment is in place on both sides of the plate boundary along its entire length.
“Accurate assessment of earthquake probability requires a lot of data, which we just don’t have at this time for the Caribbean,” Cooke explains. “Of course the effective mitigation of earthquake hazards doesn’t just depend on assessment of earthquake probability. Good building code and disaster plans are also needed by all communities living in areas of active faulting.”
Cooke and colleagues in her UMass Amherst lab are among only a handful in the world who use a more accurate and sensitive wet clay box rather than sand box for fault modeling. While sand is easier to work with at the outset, it does not “remember” a fault cut as accurately. Clay is more like real Earth in expressing discrete slips along a fault line.
Cooke says anything we can do before an earthquake strikes to better understand how a fault is behaving, how it’s accumulating stress and how it might relieve that stress in a quake will help us understand the physics of the fault better and help prevent losses. She uses both numerical models in the computer and analog models in the clay in order to better understand tectonic systems.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
