Bringing historical seismic reports and modern seismic risk maps into alignment, and a roundup of stories from our newsletter, ScienceAdviser

First on the show this week, a roundup of stories with our newsletter editor, Christie Wilcox. Wilcox talks with host Sarah Crespi about the oldest ice ever found, how well conservation efforts seem to be working, and repelling mosquitoes with our skin microbes.

Next on this episode, evaluating seismic hazard maps. In a Science Advances paper this week, Leah Salditch, a geoscience peril adviser at risk and reinsurance company Guy Carpenter, compared modern seismic risk map predictions with descriptions of past quakes. The analysis found a mismatch: Reported shaking in the past tended to be stronger than modern models would have predicted. She talks with Crespi about where this bias comes from and how to fix it.

This week’s episode was produced with help from Podigy.
