     • The Los Angeles basin is a polyphase Neogene basin within the San Andreas transform system between the Pacific and North American plates. The basin was initiated in the mid-Miocene by widespread extension associated with significant strike slip and rotation of the Transverse Ranges of southern California.

   What is the Los Angeles Basin?

   • The Los Angeles Basin, into which more than 80 communities of Los Angeles County are crowded, is a trough-shaped region bounded on three sides by the Santa Monica, Santa Susana, San Gabriel, San Bernadino, and Santa Ana Mountains. On its fourth side, the county looks out over the Pacific Ocean.

   How did the Los Angeles Basin form?

   • The Los Angeles basin formation consisted of both regressions and transgressions of the west coast shoreline. This tectonic activity along with volcanic activity helped build the Los Angeles basin into what it is today. The Los Angeles Basin is considered one of the smallest petroleum basins in the world.

   What is the stretch factor of the Los Angeles Basin?

   • The basin has a stretch factor of 2.6 in the centre grading to 1.3 at the edges and is in approximate isostatic equilibrium. The Los Angeles Basin is a Miocene-age pull-apart basin that was formed by the passing of the Pacific-Juan de Fuca-North America triple junction by southern California (Nicholson et al. 1994; Ingersoll & Rumelhart 1999 ).

   Why is the LA Basin a source of rock?

   • This can cause corrosion to metallic materials, such as tanks, pipelines, and other objects that come in contact with soil. The LA basin’s sediment became source rocks when the sediments sat in cool stagnant water in very deep depths, around 1,600 feet deep, during the last marine transgression.

   Why is the LA Basin important?

   • The LA Basin has been extensively studied over the last few decades because it is a significant oil-production area (Wright 1991 ), and because it is a major concern for the seismic hazard evaluation for the area (Olsen 2000; Komatitsch et al. 2004 ).

   Written histories of the LA River typically begin when the LA basin was still an ocean, up to 10 million years ago. With seismic uplift, the ocean receded, leaving the Santa Susana, Santa Monica, and San Gabriel mountain ranges in its place. The LA River traversed the lowest passages.
