SSA 2026 Session: Source Properties of Microearthquakes: Insights from Laboratory, Induced, and Natural Events

[Hilary Chang]

Dear Colleagues,

We invite you to submit an abstract to our session "Source Properties of Microearthquakes: Insights from Laboratory, Induced, and Natural Events" at the SSA 2026 Annual Meeting in Pasadena, California (April 14–18).

The submission deadline is Jan 13 (Tue), 2026, 11:59 PM Pacific Time. Please see more information on the meeting website: https://meetings.seismosoc.org/

Session summary:

Microearthquakes provide a unique perspective for exploring earthquake source mechanisms and fault dynamics. Whether recorded under controlled laboratory conditions, induced by industrial activities, or occurring naturally, their source properties, such as estimated energy release and stress drop, provide critical insights to the rupture processes. This session welcomes contributions from seismology, rock mechanics, geophysical monitoring, and numerical modeling, particularly studies that integrate multi-scale and multi-source data, including high-precision locations, waveform inversion, stress and friction experiments, and comparative analyses of induced and natural events. By combining laboratory experiments, field observations, and numerical modeling, we aim to deepen our understanding of microearthquake source physics and advance the scientific knowledge base for earthquake hazard forecasting and risk mitigation. We especially encourage submissions that uncover subtle differences in source processes or propose innovative monitoring technologies and data analysis methods.
