Staff and researchers at the Broadband Seismic Data Collection Center are involved in many research projects, primarily related to seismology.

Anza Network Deployment

A network consisting of 22 stations has been deployed in Southern California over the last 20 years. The stations are located either within, or adjacent to, the San Jacinto Fault Zone - a seismically active region. The stations record seismicity in real-time, sending the information to our relay station at Toro Peak by line-of-sight telemetry. The data packets are then sent to our servers housed at SIO and stored in our real-time databases. Researchers use this real-time streaming data source to try and better understand seismicity in active regions.

Tien Shan Network Deployment

The Tien Shan network is composed of the KNET , Kaznet and GHENGIS digital broadband stations and together they contribute to the Central Asia Bulletin. We are currently processing seismic data from this very active region. The data collected will help our researchers better understand eathquake focal mechanisms.

BBArray / Parkfield

A broadband array was deployed at the Parkfield fault zone, California to facilitate seismic imaging of the San Andreas fault zone. The specific goals of the project are to address the following:

Where exactly is the seismogenic zone in relation to the surface trace of the San Andreas fault?
What is the relation between the properties of the rocks in the borehole and the fault zone as a whole, and what are the implications of these properties for earthquake generation?

Microearthquake relocation studies

Relocation of microearthquakes, using seismic waveform cross-correlation, reveals organized patterns of fault sub-structure. These patterns lead us to ask questions regarding fault complexity, similarity and the triggering mechanisms between microearthquakes.

Static Coulomb stress change analysis

Estimates of the static Coulomb stress changes resulting from one earthquake at the site of a subsequent earthquake can be inaccurate by as much as two orders of magnitude when the uncertainties in fault parameters (strike, dip, and rake) are large (> 30 degrees).

Visualization of seismicity

Traditionally seismologists look at 2-D X-Y plots of a timeseries of the displacement of a seismometer in the North-South, East-West and Up-Down [X-Y-Z] directions. The 3-D nature of the data is ideal for stereo visualization. WiggleView is a program developed at the Electronic Visualization Laboratory at the University of Illinois at Chicago in consultation with seismologists in the Broadband Seismic Data Collection Center that lets you see the simultaneous recording of three channels of seismic data in response to an event.
