UETN Tech Summit

The University of Utah Seismograph stations operates a network of 230+ stations in and around Utah and Yellowstone National Park.   As an organization, we're responsible to the State of Utah and the US Geological Survey to monitor for, locate and analyze earthquakes in these regions.   To accomplish our mission, we rely heavily on UETN for data flow. We work with many technologies and have a variety of operational tasks we focus on: * Data from our stations is sent over a variety of means including radio, microwave and fiber to one of our regional acquisition nodes.   Most of these nodes are located at Universities in Utah (USU, UVU, DSU, USUE, U of U).   Data then flows to our processing systems at the University of Utah and our hot backup site at Richfield. * Since we're always-on, our disaster recovery plans include our hot backup site at Richfield that is continuously processing data, as well as sending our data to the National Earthquake Information Center (NEIC) in Golden, CO. * We use Raspberry Pi computers  at individual stations to bridge 1990's-era serial technology to modern networking and provide a capability to buffer data in the event of a network outage.   * We also use Raspberry Pi computers at several mountain-top locations in Utah and Yellowstone to capture & buffer data. * We generate about 2-4TB of continuous data per year, which we maintain in a long-term archive.  We also have some big data projects that can generate 10+TB of data in just a couple of weeks. * We use common network monitoring systems like MRTG and Nagios to check on the health of our network.
