FDSN code YI (2017-2017) Operated by University of New Mexico (UNM)
Network name Mount St. Helens 3C Node Array (MSH 2017) Deployment region United States
Start date Aug. 16, 2017 End date Sept. 26, 2017
Short description

The deployment used 3-C nodes with 5-Hz geophone to record continuous passive data at Mount St. Helens for about 35 days. The array consisted of 140 nodes total. 90 were distributed along a trail that forms a ring around the volcanic edifice near tree-line, with about 600 m spacing along the trail. Additionally three compact beamforming arrays were deployed: one outside the ring of nodes and two within the summit crater inside the ring of nodes. The deployment was carried out as a collaboration between University of New Mexico (B. Schmandt), USGS CVO (W. Thelen, S. Moran), and University of Oregon (A. Thomas).
