Some Asteroids and Meteorites Formed Less Than 2 Million Years After Solar System’s Birth

In a new study, a research team used advanced geochemical dating and analysis techniques to reveal that some asteroids and meteorites, such as Ryugu and Ivuna, originate from celestial bodies that formed less than 2 million years after the beginning of the solar system. This coincides with a period when the solar system was forming its first generation of planetesimals, the building blocks of planets. 

California Earthquakes and What the Next ‘Big One’ Could Look Like

At the August Davis Science Café, Michael Oskin led a conversation titled “Earthquakes in California: What Might the Next ‘Big One’ Be Like?” Through field observations, high-resolution topography and various geochronological techniques, Oskin is studying the relatively recent geological record to better understand the tectonic processes and crustal deformations surrounding earthquakes.

Why Earthquake Science Matters

In this video, UC Davis observational seismologist Amanda Thomas discusses the causes of the Venezuela doublet, why earthquake science matters and how Thomas’ research is helping us learn more about the tectonic shifts beneath our feet.
