Quantifying Seismic Source Parameter Uncertainties

We use data from a small aperture array in southern California to quantify variations in source parameter estimates at closely spaced stations (distances ranging from ∼7 to 350 m) to provide constraints on parameter uncertainties. Many studies do not consider uncertainties in these estimates even though they can be significant and have important implications for studies of earthquake source phy...

An Intelligent System for Seismic Source Localization

In a stationary sensor situation, locating signals arriving from different directions can be achieved by using multiple sensors placed at different locations. Different methods for locating seismic signals using an array of seismometers have been examined. Matched field processing is a method for source localization whereby model fields are calculated and compared to measured data.

A Biological Model for Directional Sensing of Seismic Vibration

There are many applications for a compact device that is capable of indicating the direction of propagation of substrate vibration. In order to develop effective devices for this purpose, it can be helpful to examine biological systems that have evolved specialized sensory systems for finding a vibration source. We are studying an insect model of vibration localization that provides an approach...
