Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Recent Innovations in Geophone Array Seismology

The availability of geophone systems that allow continuous recording of seismic signals has opened up many new directions and applications in seismology research. Compared to broadband sensors, these geophone systems are generally cheaper and easier to deploy. These systems can be rapidly deployed (e.g., important for aftershock studies) and have a minimal environmental impact (e.g., important in sensitive areas). The low cost and ease of deployment also allows these instruments to be deployed in very large numbers, as large N arrays, which can reduce or eliminate spatial aliasing by recording a well-sampled wavefield. These geophones typically have a corner frequency of 5-Hz or 10-Hz and can record single or 3-component data. As a result, they are ideal for crustal-scale, high-resolution imaging studies using both active and passive sources.

In this session, we invite abstracts that are related to geophone array, full wavefield, or large N seismology, broadly defined. Studies can include, but are not limited to, instrument/sensor development, ambient noise tomography, active-source and earthquake seismology, and microseismicity, aftershock, and other environmental seismic signal monitoring. We particularly encourage abstracts that are related to the IRIS Oklahoma community full-wavefield experiment.

Session description:

The devastating mega-tsunamis of the past decade (Indian Ocean 2004, Chile 2010, Japan 2011) have triggered a large wave of research focused on this kind of natural disaster. A number of new tools from computational sciences were introduced into the community and today the simulation based knowledge creation has accelerated into a new level of capabilities for near-realistic complex simulations. This session aims to display the state of the art in today’s complex modeling capabilities in simulating realistic source mechanisms and tsunami coupling by combining novel mathematical equation sets, advanced simulation techniques and scientific computing tools to solve high fidelity modeling problems. 3D physics based rupture models for earthquake-induced tsunami events represent one such example, where it is possible to simulate realistic dynamic ruptures, including the earth crust displacements, seismic wave release and dispersion for realistic geometrical set-ups. Modeling of failure mechanism due to slope instability and induced submarine landslide dynamics adopted for tsunami modeling purposes reveals more complex volume emplacement processes than traditional block sources. Source mechanisms related to volcanic activity, such as pyroclastic flows entering the water, and underwater explosions call for yet another type of advanced modeling techniques like two-phase flow techniques. These lead to better coupling results for the interaction of solids and fluids in the excitation of tsunami waves. The list of examples could be extended. An important question is how to incorporate such complex sources in probabilistic tsunami hazard assessment (PTHA) in order to give societies proper guidelines for future planning and mitigation measures. We invite abstracts that present such an example: a new simulation strategy, a novel equation set, a high-performance computational tool, an advanced numerical method for realistic complex tsunami source interaction, as well as studies assessing the sensitivity of the modeled tsunami impact to the complexity and accuracy of the source model, or examples of PTHA considering complex source models.
