GEO Wednesday: How earthquakes work

Lecture by François Renard, Professor of Earth Sciences at the Njord Center and the Geoscience Department at UiO.

In the Ancient Greece, earthquakes were attributed to the collapse of air bubbles in the underground, and only during the 20th century comprehensive theories that related earthquakes to the breaking of rocks and friction along tectonic faults were developed. A major challenge when studying earthquakes is that most of them nucleate at depth in the Earth and can be observed only by using surface measurements collected with seismometers, satellites or field studies of faults. In the past fifteen years, the discovery of “slow” earthquakes along major active faults has changed our view on how tectonic plates move and dissipate energy.

In this popular science presentation, François Renard will answer the following questions: What is the velocity of an earthquake? Can earthquakes be slow? Why did Mount Everest loose height in 2015? Are earthquakes predictable?

The event will be streamed live

GEO Wednesday

Once a month in the relaxed atmosphere of the Science Library geoscientists at the University of Oslo will present their research and thereby introduce geosciences to a wide audience, from first year Bachelor students to curious colleagues at the university. It is possible to ask questions after the presentations.

The talks are in Norwegian or in English.
Waffles and coffee/tea will be served.

All are welcome!
