For the last seven decades, Earth has been operating in unprecedented ways, leading many researchers to argue that we have entered a new geological epoch known as the Anthropocene.“While it may not have been formally accepted onto the geological time scale, the Anthropocene is real and its effects have drastically and irrevocably changed the living conditions on our planet,” said Julia Adeney Thomas, a professor of history at the University of Notre Dame.

A pioneering study has unlocked new insights into the immediate behavior of the Earth's crust following earthquakes. By applying sub-daily Global Positioning System (GPS) solutions, researchers have precisely measured the spatial and temporal evolution of early afterslip following the 2010 Mw 8.8 Maule earthquake. This innovative approach represents a significant advancement in seismic analysis, providing a more accurate and rapid depiction of ground deformations that are crucial for assessing seismic hazards and understanding fault line activities.

In the months that followed NASA’s Double Asteroid Redirection Test (DART) mission, which sent a spacecraft to intentionally collide with an asteroid moonlet, the science team verified that kinetic impact was a viable deflection technique, proving one effective method of preventing future asteroid strikes on Earth.Since then, researchers have continued studying data collected from the successful experiment, focusing specifically on surface features of the binary asteroid system, composed of moonlet Dimorphos and parent asteroid Didymos.
