AOGS Session: Advances in Understanding Induced Earthquakes

[ZI, Jinping]

Dear colleagues,

We invite you to submit abstracts to induced sessions at the Asia Oceania Geosciences Society(AOGS) 2026 Annual Meeting in Fukuoka , Japan (August 2–7). The abstract deadline is 23 January (UTC+8) and the submission portal is https://www.asiaoceania.org/AOGS2026/Home

Session details:

Over the past two decades, the rapid growth of subsurface industrial activities—such as fluid injection and extraction, mining, reservoir impoundment, geothermal energy production, and CO₂ sequestration—has triggered a wide spectrum of earthquakes worldwide. These induced seismic events, ranging from microseismicity to moderate and occasionally damaging earthquakes, have drawn increasing attention from both the scientific community and society due to their implications for public safety, energy sustainability, and seismic hazard mitigation. At the same time, they offer unique opportunities to investigate earthquake nucleation, fault reactivation, and the coupling between fluid, stress, and rock properties under conditions where human operations provide known perturbations.

This session aims to unite researchers across seismology, geodesy, geology, geomechanics, hydrology, and engineering disciplines to discuss the latest advances in understanding the physics and impacts of induced earthquakes. We welcome contributions that integrate observational, experimental, and modeling approaches to illuminate the mechanisms, evolution, and hazard implications of induced seismicity.

We invite studies including, but not limited to:

1) Triggering physics and fault mechanics of induced earthquakes, including pore pressure diffusion, poroelastic stress, and aseismic slip coupling.

2) High-resolution seismic and geodetic observations using dense arrays, borehole sensors, and satellite data to resolve spatiotemporal fault activation.

3) Numerical and laboratory modeling of coupled hydro-mechanical processes and fault stability.

4) Comparative analyses among fluid injection, extraction, mining, and reservoir-induced settings to identify universal versus site-specific behaviors.

5) Risk assessment and mitigation strategies, such as real-time monitoring, traffic-light systems, and physics-based hazard forecasting.

By fostering multidisciplinary dialogue, this session seeks to advance the fundamental understanding of fault activation driven by human activities and to promote science-informed frameworks for safer and more sustainable subsurface resource development.
