09.06.2017 | OASIS data hub launched, offering flood data for the Danube river catchment

How can a community be enabled to protect against future floods or insurers calculate flood losses? Data sets are needed. These data are now provided by the OASIS community with the OASIS data hub. With the participation of the GFZ section Hydrology the data hub was officially launched last Monday in London.

08.05.2017 | Improving embankment dam safety – A satellite supported feasibility study

Embankment dams are built to form water reservoirs, to supply hydro power stations or for flood control. Depending on the volume of water stored the dams are exposed to enormous hydraulic pressure. Due to this, about ten severe damages occur globally within a decade. An international team of three scientists from Iran and Germany with the participation of Mahdi Motagh, GFZ section Remote Sensing, now demonstrated how the monitoring of embankment dams can be improved by satellite data, at the example of the Masjed-Soleyman dam in Iran.

24.04.2017 | Forecasting magma movement through the crust

Assessing the hazard of volcanic eruptions requires knowledge on where exactly eruptive fissure will be located. Scientists from the Institut des Sciences de la Terre, France, and the GFZ have developed a method to forecast how fast a volcanic dike propagates through the crust and in which direction it will grow. Their study, published in the Journal of Geophysical Research: Solid Earth, was now distinguished as a “research spotlight” by the news platform EOS of the American Geophysical Union AGU. Like this, EOS honors “the best accepted articles” that were published in an AGU journal.

18.04.2017 | Diamonds log their travel to the depth

Microscopic inclusions have tremendous internal pressure – and witnessed an eventful past | Recently, a team from the Hebrew University Jerusalem and from the GFZ studied nanometer-sized inclusions in diamonds. Like a logbook, they record the travel of the diamonds to the base of the transition zone above the lower Earth´s mantle over millions of years. Now, this story is told by the team around the first author Oded Navon, Hebrew University Jerusalem, in the journal Earth and Planetary Science Letters.

05.04.2017 | Megathrust earthquakes trigger themselves – Mechanisms behind earthquake cycles at Chiles plate boundary discovered

When a phase of relative seismic quiescence of decades to centuries is followed by a short phase of strong seismic activity of several days or years, scientists refer to it as a megathrust earthquake cycle. A team of five GFZ scientists, a Chilean colleague, and first author Daniel Melnick from the University of Potsdam investigated the mechanisms behind these mega earthquake cycles at the Chilean plate boundary. The results, published in the scientific journal Geophysical Research Letters, are now distinguished as “research spotlight” by the news platform EOS of the American Geophysical Union AGU. Like this, EOS honors “the best accepted articles” that were published in an AGU journal.

14.03.2017 | A major man-made environmental disaster 1,800 years ago

Water withdrawal for irrigation led to low levels or even desiccation for lake Lop Nur in western China. It was probably the cause for the decline of Loulan Kingdom.

21.02.2017 | The heat of the Upper Rhine Graben as a future energy supplier?

Under what conditions does the underground serve as a supplier for geothermal energy? Within the EU funded project IMAGE „Integrated Methods for Advanced Geothermal Exploration“, the PhD student Jessica Freymark investigates the characteristics of the Upper Rhine Graben and its potential as a supplier for geothermal energy. Together with colleagues from the GFZ, the RWTH Aachen, the TU Darmstadt, and the Hessian Agency for Nature Conservation, Environment and Geology, she now has published her results in Tectonophysics.
