中文摘要
本研究利用现代波形反演技术, 为了确定所有的震源参数和旅行时间, 大到中等规模的地震发生在200 在过去的25年里,Kuril-堪察加俯冲带的地壳厚度增加了2.5km。 所得到的数据将用于反演三维结构, 上地幔,并研究应力方向在 俯冲板片 我们的目标是解决这样一个问题, 板块在670公里的边界处停止或穿过进入 下地幔是影响地球模型的重要问题 动力学和地幔的化学分层。
英文摘要
This research is to use modern techniques of waveform inversion to determine both source parameters and travel times for all large to moderate-sized earthquakes that occurred deeper than 200 km in the Kuril-Kamchatka subduction zone in the past 25 years. The resultant data will be used to invert for 3-D structure in the upper mantle and to investigate the stress directions in the subducting slab. The goal is to address the question of whether the slab stops at the 670 km boundary or passes through into the lower mantle, a significant question affecting models of earth dynamics and the chemical layering of the mantle.
