Microtremor Data Collection in the San Fernando Valley Basin, 2024

The San Fernando Valley Basin (SFVB) is a notable sedimentary basin located in southern California, within the greater Los Angeles region. Situated between the Santa Monica Mountains to the south and the San Gabriel Mountains to the north, the SFVB is part of the Transverse Ranges geologic province. This basin is characterized by relatively flat topography, with an elevation that ranges from sea level to approximately 1,500 feet. The SFVB is seismically active due to its proximity to the San Andreas Fault system and the presence of the Sierra Madre and Santa Susana Faults. As part of ongoing research efforts, 12 microtremor measurements have been conducted throughout the region. These measurements will add to the Shear Wave Velocity Profile Database (VSPDB).
