Deployments of Seismometer Arrays for HVSR and MAM Data Collection at Tarzana Clubhouse (CE 24103) and LA VAMC Brentwood (NP 638)

The Nweke Research Group conducted field testing  to collect data for Horizontal to Vertical Spectral Ration (HVSR) and Microtremor Array Method (MAM). The field tests were conducted at two locations: (1) Nearby the Tarzana Clubhouse (Network/Station code = CE/24103) which recorded large amplifications in ground shaking during the 1994 Mw 6.7 Northridge Earthquake; and (2) … Read More
