San Pedro Bay

The Port of Long Beach, in cooperation with the Port of Los Angeles and the Corps of Engineers, has been working on the development of a Master Plan for the San Pedro Bay area. This Master Plan, nicknamed the "2020 Plan", is intended to project the Port's land and channel requirements through the year 2020. Any landfill expansion program would be implemented in phases throughout the life of the Master Plan. The initial phases of such a plan would greatly limit the ability of the Port to revise the future configuration of landfill phases, making it important for the Port to determine a final landfill configuration before implementing the early phases. In developing the 2020 Plan, the Port projected a need for approximately 2,600 acres of additional land. In attempting to turn this 2,600 acre figure into a landfill scheme, the controlling agencies had to take a number of factors into consideration, including (1) water quality and tidal circulation; (2) potential ship motion problems; (3) additional berths required for future development; (4) land and waterside transportation corridors required; (5) availability of dredge material for creating the land; (6) available areas for creating landfills; (7) efficiency of land usage in various configurations; (8) types of ships anticipated to use the new landfills; (9) types of terminals anticipated to be located on the new landfills. The Port of Long Beach developed two basic schemes which addressed the requirements listed above. In either case, the landfill configuration for the Port of Los Angeles remained the same. The first scheme (called the island scheme, Figure 1) had the advantage of more closely matching the proposed Port of Los Angeles development. Water quality and tidal circulation would be improved with this scheme. The second scheme (called the horseshoe scheme, Figure 2) created a channel on the Long Beach side which did not match the orientation of the channel on the Los Angeles side. This channel was better protected from wave forces than the island scheme, where ships would have to be berthed along the exposed southerly boundary.

Energy Amplification

Abstract We have investigated energy amplification observed within Greater Los Angeles basin by analyzing regional waveforms recorded from several Nevada Test Site (NTS) nuclear explosions. Although the stations are located nearly at the same azimuth (distances ranging from 350 to 400 km), the seismograms recorded in Compton (the central part of the basin), Long Beach (the southern edge of the basin), and downtown Los Angeles are remarkably different, even for a common explosion. Following the onset of Lg waves, the Long Beach sites have recorded surface waves for more than 100 sec. From one explosion, the sites within downtown Los Angeles have recorded seismograms with strong 3-sec surface waves. These waves are not observed on the seismograms recorded in the neighboring hard-rock site California Institute of Technology (CIT) station. Thus, they must have been generated by local wave guides. Numerically, we modeled these 3-sec waves by convolving the CIT seismogram with the response of a sedimentary strata dipping gently (about 6°) from CIT toward downtown. We also examined the irregular basin effect by analyzing the variation of cumulative temporal energy across the basin relative to the energy recorded at CIT from the same explosion. Variation up to a factor of 30 was observed. To model the energy variation that is caused by extended surface waves in the Long Beach area, we used numerically simulated site transfer functions (STF) from a NNE-SSW oriented two-dimensional basin structure extending from Montebello to Palos Verdes that included low-velocity sedimentary material in the uppermost layers. These STFs were convolved with the CIT seismogram recorded from the MAST explosion. To simulate elongated duration of surface waves, we introduced in the upper sedimentary structure some discontinuous microbasin structures of varying size, each microbasin delaying the seismic waves propagating through them. Consequently, the surface-reflected phases through these structures are delayed and reflected into the upper medium by the underlying interfaces. This mechanism helps delayed energy to appear at a later time and result in a longer time duration at sites located at southern edge of the basin.

Insight Into

In this talk, delivered at the 2014 California State University, Long Beach, symposium celebrating the 75th anniversary of the publication of Ask the Dust, Cooper recounts the story of how he came to discover a remarkable letter, to that point unknown, written by John Fante in 1933. Addressed to fellow Italian American writer Jo Pagano, who like Fante had ventured west from Colorado to seek writing success in Los Angeles, the letter provides insight into the crippling doubts and frustrations that burdened the young Fante even as it reveals his deep-seated confidence that he would one day write a great novel. Published here for the first time, this letter prefigures another remarkable Fante letter, the one written in 1938 that is now known as the Prologue to Ask the Dust.
