“We needed to know how far and how fast the event could travel”

Brienz has just been evacuated for the second time. The decision is based, among other things, on thousands of simulations that ETH professor Jordan Aaron has produced using a computer model he developed. In an interview with ETH News, he explains why this model was used.

Scientists explore the complexity of rocks within the Earth's crust

A team of EPFL scientists has provided insight into the mechanisms at work in geothermal reservoirs located deep underground, known as supercritical reservoirs. Through a combination of computer simulations and lab experiments, they showed that rocks located between five and eight kilometers deep in the Earth’s crust are also permeable to fluids.

Planets contain more water than thought

Most of a planet’s water is generally not on its surface but hidden deep in its interior. This affects the potential habitability of distant worlds, as shown by model calculations of researchers at ETH Zurich and Princeton University.

Millions of years for plants to recover from global warming

Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term climate effects of disturbed natural ecosystems - its implications both in geological history and for today.

New class of Mars quakes reveals daily meteorite strikes

An international team of researchers combine orbital imagery with seismological data from NASA’s Mars InSight lander to derive a new impact rate for meteorite strikes on Mars. Seismology also offers a new tool for determining the density of Mars’ craters and the age of different regions of a planet.

Detecting storms thanks to GPS

Researchers at ETH Zurich have succeeded in detecting heavy precipitation events directly with GPS data. The results of their study could significantly improve meteorological monitoring and forecasting.
