“…The history records no M 7.0 earthquake events occurred in this region and the seismic activity in this region was relatively weak not only in intensity but also in quantity in the past. A few studies have been made regarding its activity and potential seismic risks in the future [22]. However, since 2013, 7 events of magnitude from M 5.0 to M 5.9 have occurred in this region.…”

Abstract:It is well known that earthquakes are a regional event, strongly controlled by local geological structures and circumstances. Reducing the research area can reduce the influence of other irrelevant seismotectonics. A new sub regiondividing scheme, considering the seismotectonics influence, was applied for the artificial neural network (ANN) earthquake prediction model in the northeast seismic region of China (NSRC). The improved set of input parameters and prediction time duration are also discussed in this work. The new dividing scheme improved the prediction accuracy for different prediction time frames. Three different research regions were analyzed as an earthquake data source for the ANN model under different prediction time duration frames. The results show: (1) dividing the research region into smaller subregions can improve the prediction accuracies in NSRC, (2) larger research regions need shorter prediction durations to obtain better performance, (3) different areas have different sets of input parameters in NSRC, and (4) the dividing scheme, considering the seismotectonics frame of the region, yields better results.

“…The focal mechanisms of these earthquakes, GPS data (Wang et al, ), and in situ stress measurements all imply that nearly east–west compression has resulted in right‐lateral strike‐slip with a reverse slip component on the faults (Hsiao et al, ; Li et al, ; Liu et al, , ; Yin et al, ; Zhu et al, ). Studies of paleo‐earthquakes and shallow seismic profiles have also revealed significant activity of the TLFZ in the late Quaternary (Huang, Liu, & Kusky, ; Liu, Zhu, Zhai, Gu, & Liu, ; Min, Jiao, Zhou, Shen, & Chen, ; Min, Liu, Jiao, Shen, & Pan, ; Yin et al, ; Zhu et al, ). This fault has become a focus of research because of its seismicity and potential risk in the late Quaternary (Min et al, , ; Yu, ; Zhang et al, ; Zhu et al, ).…”

“…Recently, Min et al (, ) discovered the Holocene‐active segments of the YYFZ (Tonghe in Figure c, Shulan in Figure d) based on high resolution SPOT‐5 satellite images, trench excavations, sample dating and surface investigations. Holocene tectonic activity on the section of the YYFZ in Tonghe in Heilongjiang Province displaced a sedimentary layer with an age of approximately 1 730 ±30 years BP and formed a surface fault scarp that is 1–2 m high, and the segment of the YYFZ in Shulan in Jilin Province had a 14 C displacement date of 4 410 ±30 years BP, which changed the traditional viewpoint that the YYFZ had weak activity or was inactive in the late Quaternary.…”

Deformation within the Indo-Asian Collision Zone is accommodated on a complex network of faults spanning thousands of kilometers in any direction. In order to characterize faulting in the orogen for seismic hazard assessment, a new fault database was compiled, resulting in ˜1000 fault traces mapped at around 1:100,000. A block model was created simultaneously with the fault mapping to estimate robust, internally-consistent slip rates on all mapped faults. The block model inverts >3000 GNSS velocities and ˜200 Quaternary geologic slip rates. The results yield slip rates that are generally quite consistent with geologic estimates, indicating that decadal and millenial-scale deformation rates are compatible. Additionally, the great strike-slip faults of the orogen are the dominant faults of the orogen's interior, accumulating and redistributing slip from linked, subordinate fault networks in a way similar to transfer faults within a basin or thrust belt, but on much larger scale.
