Data from: Seismicity Migration from Fluid Injection: Laboratory Experiments and Numerical Models Illuminate Volume-Driven versus Pressure-Diffusion-Driven Migrations
Song, Jun Young; Liu, Lingfu; Arson, Chloé; McLaskey, Gregory C. (2025-12-23)
These files contain data supporting all results reported in Song et al. We found: Fluid injection into the subsurface can induce seismicity by reactivating shear rupture, which typically produces larger earthquake magnitudes than tensile rupture. In laboratory shear rupture experiments, pressurization of the entire fault is often limited because large unconfined samples allow fluid to leak at free surfaces. In this study, we investigated shear fault reactivation by directly injecting fluid into a PMMA fault (760 mm long, 76 mm high) formed as the interface between two separate PMMA blocks. To prevent leakage in the 76 mm dimension, we made a low permeability barrier by coating the outer edges of the fault with Teflon tape. Fluid pressure then extended along the 760 mm dimension, resulting in the migration of seismicity away from the injection well. Changes in injection rate and fluid viscosity revealed two mechanisms: (1) slow injection rate or low-viscosity fluid caused seismicity migration governed by pressure diffusion, and (2) fast injection rate or high-viscosity fluid caused seismicity migration proportional to injected volume. Simulations with a 2D poroelastic model showed that seismicity migrated with the fluid pressure front in the volume-driven regime, whereas fluid pressure advanced well ahead of seismicity in the pressurediffusion-driven regime. These results highlight that Teflon tape effectively sealed faults and controlled fluid flow, and that injection rate and fluid viscosity have a strong impact on fault slip and induced seismicity.
Data from: Fully Contained Laboratory Earthquakes: The Effect of Asperity Aspect Ratio and Free Surfaces
Cebry, Sara Beth L.; Song, Jun Young; McLaskey, Gregory C. (2025-12-23)
These files contain data supporting all results reported in Cebry et al. We found: Corner frequency (fc) and seismic moment (M0) are key parameters derived from seismic signals that are used to characterize
earthquake stress drop, rupture area, and slip. These parameters are also affected by fault geometry and boundary conditions. However, the systematic study of these effects in laboratory settings has been
challenging. This study presents laboratory earthquake experiments that examine how rupture dynamics are influenced by (1) the aspect ratio of rectangular PMMA velocity-weakening (VW) asperities
surrounded by the Teflon velocity-strengthening (VS) patches, and (2) whether the sides of a VW asperity are confined with VS patches or are free surfaces. We found that increasing confinement by
reducing free surfaces or increasing the VW asperity aspect ratio stabilizes fault slip, so that higher normal stress is required to transition from aseismic to seismic slip. Increased confinement and high
aspect ratios also reduced M0 and increased fc, both of which were determined from the radiated seismic waves. M0 and fc were primarily controlled by the shorter dimension of the VW asperity. Analysis
of high-frequency acoustic emission signals revealed that ruptures on high-aspect-ratio VW asperities propagated more unidirectionally, whereas ruptures on square VW asperities were more complex. Further, the high-aspect-ratio asperities were more likely to be eroded by surrounding VS regions while lowaspect-ratio asperities were more likely to rupture into the VS surroundings. These results demonstrate that both the confinement from surrounding stable areas and the geometry of the seismogenic patch can affect rupture nucleation, propagation, and seismic source characteristics.
Free vs. Paid Listings: How Hotels Can Optimize Google Hotel Finder
Wang, Frances; Larson, Jeff; Anderson, Christopher (2025-12-23)
This experiment shows exactly when Google Hotel Finder’s free organic link is enough and when paying for sponsored placement delivers real returns for hotels. Paid visibility meaningfully increases total demand, shifts more bookings into the direct channel, and boosts revenue when availability is high and impressions are low. But when the hotel is already getting strong exposure or inventory is tight, paid ads produce little incremental benefit. The result: a clear, evidence-based playbook for when to activate and pause paid participation on Google Hotel Finder.
