The importance of diatoms for understanding subduction zone earthquakes in Alaska (2024)
Journal Article
Summers, G., Engelhart, S., & Woodroffe, S. (2024). The importance of diatoms for understanding subduction zone earthquakes in Alaska. PAGES Magazine, 32(1), 24-25. https://doi.org/10.22498/pages.32.1.24

Great subduction-zone earthquakes (moment magnitude [Mw] >8) pose a significant threat to human populations, the environment and infrastructure, yet the spatial and temporal patterns of these hazards before the 20th century are often poorly constrain...

Taraxerol abundance as a proxy for in situ Mangrove sediment (2024)
Journal Article
Sefton, J. P., Kemp, A. C., Vane, C. H., Kim, A. W., Bernhardt, C. E., Johnson, J., & Engelhart, S. E. (2024). Taraxerol abundance as a proxy for in situ Mangrove sediment. Organic Geochemistry, 191, Article 104767. https://doi.org/10.1016/j.orggeochem.2024.104767

Mangrove sediments are valuable archives of relative sea-level change if they can be distinguished in the stratigraphic record from other organic-rich depositional environments (e.g., freshwater swamps). Proxies for establishing environment of deposi... Read More about Taraxerol abundance as a proxy for in situ Mangrove sediment.

The USGS Powell Center Cascadia earthquake hazards working group compiled published onshore and offshore paleoseismic data along the Cascadia subduction zone, spanning sites from Vancouver Island to the Mendocino triple junction. Evidence for megathr... Read More about Compiled onshore and offshore paleoseismic data along the Cascadia Subduction zone.
