These soft wave like sculptural elements are frozen in time at various points along the highly populated Rose Canyon fault, which has a slip-rate of 1.1 mm/year. This fault has sustained at least one late Holocene rupture, with the date of the earthquake estimated to be after AD 1450. Some geophysicists have hypothesized that a concentrated earthquake involving the Rose Canyon, Oceanside, and Newport–Inglewood faults could result in an earthquake up to magnitude 7.6.
