Title: Temporal Characteristics of Earthquakes * Colloquium on Complex and Biological Systems

Time: Fri, Nov 28, 2014, 10:15am

Place: bldg 28, room 0.108

The earthquake structure is generally thought hierarchical. The earthquakes at the first level are mainshocks which trigger many earthquakes named aftershocks at the second level. Each aftershock also triggers its aftershocks at the lower level.
The statistical properties, such as distribution and correlation, of some attributes of the earthquake, like magnitude and waiting time or distance between two successive earthquakes, are essentially important for understanding the earthquake process, modeling the process, and hazard assessment. There proposed some empirical laws to describe the distributions of these attributes, particularly those of aftershocks. Also, many researchers studied the correlation of these attributes of earthquakes. Although aftershocks can be well profiled, many properties of mainshocks are still unclear.
In this talk, I'll first briefly introduce these empirical laws and some existing results. Then I'll focus on a specific problem, i.e. is the distribution of mainshocks waiting time exponential or power-law? In traditional view, it should be exponential. However, recent study shows some evidences to claim that it is power-law. Our study found that these evidences, however, are not enough to support the power-law-distribution argument.
