Mission Trails Regional Park Seismic Station

The most unique station we have recently added to our network is at Mission Trails Regional Park in San Diego (station code MTRP). The exhibit is located at the Mission Trails Interpretative Center, a museum at the Mission Trails Regional Park within the City of San Diego. The museum foundation purchased their own strong motion sensor (a KMI Etna system) and a workstation with dual-monitors for a real-time display in their Visitor Center. The public unveiling of the exhibit was held on Thursday, February 7, 2002, at 11:00 a.m. in the Visitor & Interpretive Center. Joe Morse, President of Mission Trails Regional Park Foundation, was Master of Ceremonies for the event with the City of San Diego Mayor Dick Murphy and Council Member Jim Madaffer participating in the ceremony. The collaborative efforts of staff and researchers from IGPP and SDSU were highlighted in this ceremony.

The interactive display allows visitors to view the waveforms generated by jumping up and down

Attendance at the museum is approximately 60,000 per year and the Center is a popular field trip destination for K-12 school groups. The educational component on earthquakes and seismology that this display produces is highly relevant in Southern California and San Diego. The communities served by the Center are less than 100 km west of the Elsinore and the San Jacinto faults, both of which are seismically active strands of the right-lateral strike-slip San Andreas fault system that defines the Pacific/North American plate boundary in this area (click to see map). Several other less active faults fall within the city of San Diego or lie just offshore. Earthquakes large enough to be felt first-hand by people occur several times per year with damaging events occurring on the order of every ten to twenty years, usually from large events at regional distances. Consequently, the need for awareness of earthquake causes and potential ha

View of the interactive display case

The MTRP strong motion sensor is located under the display, allowing people to jump, stamp feet, and otherwise create seismic waves that appear almost immediately on a computer monitor. An event map, updated in real-time, is also displayed with a choice of local, regional, and worldwide views of recent earthquake locations. During periods of little museum activity, which is at least 14 hours per day, the sensor records useful low noise data that are merged in real-time with ANZA seismic network data for scientific analysis. We have a data exchange with Mission Trails so they can display the regional events and real-time event locations from the ANZA network, and the ANZA network gained a new urban San Diego real-time strong motion station. This is, to our knowledge, the first case of a museum seismology display being used simultaneously as an active station in a real-time seismic network. We are currently discussing two similar implementations in other urban museum settings in San Diego county
