Geothermal Energy Research Sheds Light on Induced Earthquakes

In the pursuit of a carbon-free economy, the focus on geothermal energy extraction is intensifying. Energy producers worldwide are eagerly seeking safer methods to tap into the potential of deep underground geothermal energy. At the forefront of this effort is EPFL associate professor Brice Lecampion, leading...

AI predicts future fault slip in laboratory earthquakes

In laboratory earthquakes, an artificial intelligence approach borrowed from natural language processing much like language translation and autofill for text on your smartphone can predict future fault friction and the next failure time with high resolution. The technique, which applies AI to the fault's...

Phase transitions in olivine may be the cause of deep seismic faulting

Deep-focus earthquakes are earthquakes that occur at depths of several hundred kilometers in the mantle. Such earthquakes can cause serious disasters, such as the 1994 Bolivian earthquake, which occurred at a depth of 638 kilometers and had a magnitude of 8.3. The cause of deep-focus...

Tortoise and her egg found in new Pompeii excavations

Archaeologists in Pompeii discovered the remains of a pregnant tortoise that sought refuge in the ruins of a home destroyed by an earthquake in 62 AD, only to be covered by volcanic ash and rock 17 years later when Mount Vesuvius erupted. The 14-centimeter-long (5.5-inch-long)...

Earthquake modelers unite to compare and improve code

Movement along faults in Earth's crust can be sudden and jarring. It can occur more gradually over thousands of years. Any kind of movement along a fault might affect the stresses and other factors that contribute to subsequent movements. Scientists have developed computational physics-based models that...

Volcanoes at fault if the Earth slips

The 2016 Kumamoto earthquakes shocked the inhabitants of the western island of Kyushu. It caused hundreds of casualties and serious damage to vital infrastructure. The epicenter of the quake was traced to the Futagawa fault in a region neighboring Mount Aso which is an active volcano in...
