Thin walls with potentially fatal consequences
06.11.15 - Given the choice between safer and cheaper construction, many housing design companies in earthquake-prone developing countries see themselves forced to save on expensive construction materials and opt for the latter. EPFL structural engineers have gathered new data on how these structures respond to earthquakes, and in which circumstances they may fail.

Analyzing Lake Geneva from the air
One year after the MIR submersibles dove into the depths of Lake Geneva, the elemo program is delivering its first scientific results. The operation will be extended with a campaign to make observations above the lake surface from a sensor-packed ultralight aircraft. The same experiments are planned above Lake Baikal in Russia.

X-rays provide insights into volcanic processes
Experiments investigate processes inside volcanic materials that determine whether a volcano will erupt violently or mildly. In the experiments, an international team of scientists used a laser-based heating system to heat small pieces of volcanic material similarly to conditions present at the beginning of a volcanic eruption.

Science of the stick-slip
Scientists have succeeded in modelling what happens when two bodies slide against each other and thereby release the pressure; a discovery that has implications for the understanding of the magnitude of earthquakes. David Kammer from EPFL has developed a digital model that explains what happens at the interface between two materials when they slide against each other; like a book on a table, rubber soles on linoleum, or - more to the point - tectonic plates.

Simulations to protect the Valais
Scientists model sediment deposits carried by the Naviscence River in the Swiss Valais canton. They are simulating possible scenarios for the future of the Zinal ski area, which could be threatened by the river.

From raindrop to flood
Scientists are starting a new field campaign in the Val Ferret. They're collecting data to study how the environment influences flood rates in mountain valleys. Predicting natural disasters in order to inform and warn populations residing in risk zones is a major challenge today. “Mathematical models exist, but they still don't take into account all the data that are needed to establish reliable predictions, such as the influence of air temperature, the formation of thermal winds or the impact of precipitation,” explains Professor Marc Parlange.
