Abstract
This paper describes an application of distributions (e.g. spectrograms) to the interpretation of continuous data streams from seismic array stations. Such data representations can be used to construct an analyst in- terface for the purpose of screening large quantities of data. Three types of distributions are considered: spectrograms (energy vs. frequency and time), bearing and slowness distributions (energy vs. direction or slowness and time). The main seismic interpretation functions of detection, wave identification and association, location, and event classification can be performed from a visual inspection of an appropriate combination of distributions and trace displays. A system based on data "visualization" should have high throughput and perform well in a nuclear test ban treaty verification role.
