. The principal investigator of the ANF is Dr. Frank Vernon. The facility has developed a series o
online tools
to allow researchers and the general public to interact with data collected from over four hundred broadband

stations across the United States. These four hundred stations make up the Transportable Array component of the

project. Analysts review automated event detections and produce event bulletins including seismic phase picks which are distributed through the IRIS DMC. The ANF component of the USArray experiment is funded by the
