The hidden mechanics of earthquake ignition

Researchers unveil groundbreaking insights into earthquake nucleation, showing that slow, aseismic motion is necessary and triggers seismic rupture. The study's findings also emphasize the critical role of geometric transitions in controlling nucleation dynamics.

How fractures nucleate, propagate and stop

A team of scientists discovered that fractures propagate in starts and stops, moving through materials at high speeds. The amplitude and time between jumps depend on the viscosity of the liquid injected into the rock.

Tensile cracks can shatter classical speed limits

Researchers at Hebrew University of Jerusalem discovered supershear tensile cracks that surpass classical speed limits and transition to near-supersonic velocities. These findings challenge traditional understanding of fracture mechanics, offering new avenues for studying material properties.

Cracking the problem of river growth

A new study at MIT applies the fracture mechanics theory of local symmetry to predict river network evolution. The research found that rivers grow in a direction consistent with symmetry, driven by groundwater pressure and water table height.
