Seismological and Tectonic Analyses of the Upland Earthquakes

这笔赠款将通过SGER资助急需的支持 分析和解释1988年和1990年 加州地区高地的地震序列。 的 第二个序列是非常丰富的余震和几乎大 足以触发TIP（概率增加的时间） Keilis-Borok地震预测算法 因为洛杉矶 安吉利斯盆地正处于地震活动增强期 自1986年3月以来，与1952-1985年期间相比， 重要的是及时分析这些序列。 因为 无论是小地震还是大地震， 地震活动增加，这项研究具有一定的紧迫性 在减轻城市地区的地震灾害， 洛杉矶和圣贝纳迪诺县。 这项工作具有直接 国家地震减灾计划。

This grant will fund urgently needed support through the SGER program to cover analysis and interpretation of the 1988 and 1990 sequences of earthquakes in the Upland, California, area. The second sequence was very rich in aftershocks and almost large enough to trigger a TIP (time of increased probability) in the Keilis-Borok earthquake prediction algorithm. Because the Los Angeles basin is in an episode of enhanced earthquake activity since March 1986 as comparaed to the time period 1952-1985, it is important to analyze these sequences in a timely manner. Because both small and large earthquakes are more likely during times of increased earthquake activity, this research has some urgency interms of mitigating earthquake hazards in the urban areas of Los Angeles and San Bernardino Counties. This work has direct application to the National Earthquake Hazard Reduction Program.
