Seismology throughout the years: from blown pre-amplifiers to the internet of things — a technician’s view on seismology

An interview with Arie van Wettum In many universities, students and staff will go out into the field to deploy seismometers, collect data, and service instruments. Students get a sense of the area their data is coming from, the difficulties that are involved with deploying and recording data, and although inexperienced at the beginning, they …[Read More]

How do the ups and downs of the solid Earth influence the future of the West Antarctic ice sheet?

How do the ups and downs of the solid Earth influence the future of the West Antarctic ice sheet?

When the Antarctic ice sheet loses mass, the pressure it exerts on the underlying solid Earth decreases. As the ice sheet becomes less heavy, the Earth’s surface is not pressed down as much as before and therefore slowly rises up. In some regions, this rebound process is much faster than previously thought and could stabilise …[Read More]

What can we learn from geodynamic failure?

Artwork reading "All my faults are stress related"

In this week’s post, Mohamed Gouiza discusses the challenges of living under constant stress, paralysed by the possibility of failure and self-perceived inevitability of impending breakup. Continental rifting, of course! Oh… did you think I was talking about life as a researcher? Under tensile stress, the lithosphere stretches, the asthenosphere rises, the crust fails, and …[Read More]

Featured catchment: Water Towers of Mesopotamia: Snow feeding the cultural heritage

Importance and challenges of snow modelling in Turkey Snow and glaciers in the high mountains play a crucial role for 1.6 billion people living downstream of mountainous areas. Thus, understanding snow dynamics is crucial for downstream irrigation, hydropower, flood control etc. In eastern Anatolia, Turkey (the mean elevation is around 1140 m), much of the …[Read More]

Natural Hazards 101: The disaster cycle

Natural Hazards 101: The disaster cycle

With the Natural Hazards 101 series, we meant to bring our readers closer to the terminology often used in the field of natural hazards, but that may not be so familiar. We started defining the very concept of hazard and natural hazard. We moved then to the concept of risk, which brought us to define …[Read More]
