Mapping the invisible: how sub-daily GPS sheds light on early postseismic deformation

Chinese Academy of Sciences — Mon, 05 Aug 2024 08:05:55 EST

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.

DART Forward: Five Papers Shed New Light on Asteroids From World's First Planetary Defense Test

Johns Hopkins University Applied Physics Laboratory — Fri, 02 Aug 2024 10:05:07 EST

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.
