Estella Atekwana | Women in Leadership

From Comstock's Magazine: Estella Atekwana, dean of the UC Davis College of Letters and Science, grew up in Cameroon in Central Africa, where the measure of success was limited to those deemed to have prestigious careers. “We equated success with the medical doctor down the street, or an engineer or a lawyer,” she says. In high school, Atekwana took a geology class that expanded her horizons and ignited her interest in studying the Earth. But the teacher discouraged her from staying in the class because she was a young woman. She viewed it as a challenge and remained, finishing at the top of the class.

Evidence for Shared Earthquakes Between San Andreas and San Jacinto Faults | Alba Rodríguez Padilla

From UC Davis News: "The San Andreas and San Jacinto faults have ruptured simultaneously at least three times in the past 2,000 years, most recently in 1812, according to a new study by geologists at the University of California, Davis, and San Diego State University. The work was published Dec. 7 in the journal Geology. Large earthquakes involving multiple faults increase the threat of strong ground shaking. However, each of these faults on their own can generate a large-magnitude (7.5 or above) earthquake, said Alba Rodríguez Padilla, a graduate student at UC Davis and first author on the paper."

Kari Cooper | Putting Science Into Practice: Preparing for Volcanic Eruptions

From UC Davis Letters and Science: "Coordinating the emergency response to an erupting volcano is an all-hands-on-deck affair that leaves little time for extra work, such as answering boatloads of inquiries from researchers who want to collect rock samples. On the other hand, science done during eruptions provides essential data for understanding and forecasting future volcanic flare-ups. To help balance these interests, scientists like Kari Cooper, professor of earth and planetary sciences at UC Davis, are exploring how to prioritize public safety while maximizing the limited time and access for collecting data and samples."

Qing-zhu Yin | Dwarf Planet Vesta Is a Window to the Early Solar System

Qing-Zhu Yin is a study co-author. From the Egghead blog: The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent papers involving UC Davis scientists use data from meteorites derived from Vesta to resolve the "missing mantle problem" and push back our knowledge of the solar system to just a couple of million years after it began to form. The papers were published in Nature Communications Sept. 14 and Nature Astronomy Sept. 30.

Magali Billen | Deepest earthquake ever detected struck 467 miles beneath Japan

Magali Billen comments on the deepest earthquake ever detected, described recently in the journal Geophysical Research Letters. From National Geographic: "One spring evening six years ago, hundreds of miles underground, our planet began to rumble from a series of peculiar earthquakes. Most of Earth's temblors strike within a few dozen miles of the surface, but these quakes stirred at depths where temperatures and pressures grow so intense that rocks tend to bend rather than break."

Isabel Montañez | The Climate Archive of Caves

From UC Davis Unfold Podcast: ‘Nature Tells Its Story, Part 2’. "California boasts hundreds of caves, many of them hidden in the Sierra Nevada foothills. These caves hold much more than beautiful icicle-like stalactites and stalagmites. Trapped inside the stalagmites are tiny droplets of fossilized precipitation from climates long ago. In “Nature Tells Its Story, Part 2” of Unfold, UC Davis researchers discuss how these water droplets provide a “climate archive” that may help us predict future shifts in rain, snow and drought." In this episode: Isabel Montañez, distinguished professor, UC Davis Department of Earth and Planetary Sciences and Barbara Wortham, doctoral student, UC Davis Department of Earth and Planetary Sciences.

Tessa Hill | Hard Times for Hard Shells

From AAS: "Having a conversation about wildfires may be an unusual way to help educate people about climate change in our oceans. But for Northern California-based marine scientist and AAAS Fellow Tessa Hill, Ph.D., both topics are urgent and closely related. Deadly, fast-moving wildfires have touched nearly everyone in the region. And the fires’ link to climate change provides a non-threatening way for her to engage with her community about heat waves, both on land and in the oceans."

David Gold | NSF CAREER Award

David Gold has been granted a prestigious 5-year NSF "Early Career" award to continue his research on the interpretation of chemical biomarkers in the rock record: "An Evolutionary Framework for the Molecular Fossil Record". This grant supports David's continued use of genetics to identify what groups of living organisms have the ability to make various biomarkers that are used to trace the history of evolution, source rocks for petroleum, and pollution sources. David will also use the genetic data, calibrated to the rock record, to help pin when in the past each group gained the ability to make specific biomarkers. Early Career grants include a strong outreach component, and David will be developing courses to train early career geologists to use genetic tools for their own research. He will also be developing a mentoring program for promising Native American scholars, a group that has been historically harmed by geoscientists through land and resource theft.
