In a commentary in the Aug. 21 issue of Nature, Harry Green, Distinguished Professor of Geology and Geophysics in the Institute of Geophysics and Planetary Physics and the department of earth sciences at UC Riverside, explains that two large, deep earthquakes (depth > 300 km below the surface of the earth) that occurred in Aug. 2002 in the Tonga subduction zone were causally related.
The Tonga subduction zone is approximately beneath the Fiji Islands in the Pacific Ocean. The two earthquakes were 300 km apart from each other and the difference in their depth was 65 km. Their magnitudes were 7.6 and 7.7.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
