Surface-wave Attenuation and Crustal Anelasticity in Central North America By
The southeastern Missouri earthquake of October 21, 1965 generated fundamentaland higher-mode Love and Rayleigh waves which were recorded at numerous North American stations. Love-wave amplitude radiation patterns were determined and found to be consistent with theoretical patterns predicted by a fault-plane solution previously inferred from Rayleigh-wave data. The radiation patterns were used ...
متن کاملThe Basin and Range Province
The Basin and Range province is a broad, highly extended terrane embedded within the North Ameri-can western Cordillera that extends from Canada, through the western United States, and across much of Mexico. The province roughly occupies the space between the Cascade Ranges and Rocky Mountains in the north and the Sierra Nevada and the Colorado Plateau in the middle, and it engulfs the Sierra M...
متن کاملMagnitude of crustal extension across the northern Basin and Range province: constraints from paleomagnetism
The magnitude of crustal extension across the northern Basin and Range province is a matter of longstanding controversy; estimates range from 10 to 3009~,. Recently published estimates of extension across the southern Basin and Range province (36°N) are in the range of 80-100%. Thus, the larger values suggested for the northern part of the province (40°N) seem to require substantial countercloc...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Fully nonlinear inversion of fundamental mode surface waves for a global crustal model
[1] We use neural networks to find 1-dimensional marginal probability density functions (pdfs) of global crustal parameters. The information content of the full posterior and prior pdfs can quantify the extent to which a parameter is constrained by the data. We inverted fundamental mode Love and Rayleigh wave phase and group velocity maps for pdfs of crustal thickness and independently of verti...
