Regional mapping of the crustal structure in southern California from receiver functions
[1] Lateral variations of the crustal structure in southern California are determined from receiver function (RF) studies using data from the Southern California Seismic Network broadband stations and Los Angeles Regional Seismic Experiment surveys. The results include crustal thickness estimates at the stations themselves, and where possible, cross sections are drawn. The large-scale Moho dept...
متن کاملCrustal Thickness Variations in Southern California from Los Angeles Region Seismic Experiment Passive Phase Teleseismic Travel Times
The goal of the 1993 Los Angeles Region Seismic Experiment (LARSE93) passive phase was to collect waveform data from local and distant earthquakes to study lower crust and upper mantle structural features in southern California, particularly under the San Gabriel Mountains and San Andreas fault. During LARSE93, approximately 88 stations were deployed in a 175-km-long, linear array across the Lo...
متن کاملDormancy and germination response of Galbanum seeds (Ferula gummosa) under different hormonal pre-treatments and cold stratification
Extended Abstract Introduction: Galbanum is one of the most important native medicinal plants in Iran, and nowadays the use of its products and derivatives has become widespread in various industries. Thus, the excessive harvest of this species within its natural habitats has increased. Therefore, the species is enlisted as prone to extinction. Due to the lack of information about germination ...
متن کاملINVESTIGATION OF SEED GERMINATION CHARACTERISTICS AND RECOVERY OF GERRMINATION IN THE HALOXYLON APHYLLUM UNDER DIFFERENT TEMPERATURE AND SALINITY CONDITIONS
Haloxylon aphyllum is one of the most important species in sandy and saline areas in deserts, and some ecophysiology characters for viability in unfavorable condition have evaluated in this species. Seed germination is the critical stages in life cycle for species survival. In this study investigated salinity and temperature stresses on percentage and velocity of germination using six salinity ...
متن کاملAs the raven flies: using genetic data to infer the history of invasive common raven (Corvus corax) populations in the Mojave Desert.
Common raven (Corvus corax) populations in Mojave Desert regions of southern California and Nevada have increased dramatically over the past five decades. This growth has been attributed to increased human development in the region, as ravens have a commensal relationship with humans and feed extensively at landfills and on road-killed wildlife. Ravens, as a partially subsidized predator, also ...
