Characterizing directivity in small (M 2.4-5) aftershocks of the Ridgecrest sequence
Shanna Chu, Annemarie S. Baltay Sundstrom, Rachel E. Abercrombie
2025, Bulletin of the Seismological Society of America (115) 1177-1188
Directivity, or the focusing of energy along the direction of an earthquake rupture, is a common property of earthquakes of all sizes and can cause increased hazard due to azimuthally dependent ground‐motion amplification. For small earthquakes, the effects of directivity are generally less pronounced due to reduced rupture size, yet...

2025, Ecosphere (15)
Fire and drought are expected to increase in frequency and severity in temperate forests due to climate change. To evaluate whether drought increases the likelihood of post-fire tree mortality, we used a large database of tree survival and mortality from 32 years of wildland fires covering four dominant western North American...
Global patterns of coseismic landslide runout mobility differ from aseismic landslide trends
Alex R. Grant, Natalie K. Culhane
2025, Engineering Geology (344)
Coseismic landslides significantly contribute to human and economic losses during and immediately following earthquakes, yet very little data on the runout of such landslides exist. While well-established behavior of aseismic (e.g., hydrologically triggered) landslide runout mobility suggests strong correlation between landslide size and mobility, limited studies of coseismic landslide runout...
