Passive Seismic Tomography is an exploration technique that has been successfully applied for years in solving difficult exploration problems. Exploiting local microseismic events as seismic sources and dense microseismic networks as receivers, this methodology comprises significant numbers of continuous records that have to be thoroughly examined, in order to extract all useful information. In this scope, an integrated technique was developed for the automated analysis of microseismic events. The specific strategy consists of a detection algorithm, which involves two different options, according to the quality of the recorded data, as well as an automatic picker, based on the statistical characteristics of the seismic signals. Both automatic detection and picking procedures are followed by corrections, based on the geometry of the seismic network, aiming in reducing detection's false alarm rate and avoiding false P-and S-arrival time estimations. The performance and effectiveness of the proposed methodology is evaluated using real seismic data, recorded during a passive seismic tomography survey in Delvina, SW Albania.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
