We present the results of statistical simulation for the seismicity within the zone of interaction among the Amur, Eurasian, and Sea of Okhotsk plates where our seismological analysis revealed the Ole kma-Stanovoi seismic area, the Tan Lu zone, and the northern Sakhalin-Japan island arc. We discuss the spatial irregularities in the seismicity maxima distribution in annual cycles. It was found that when considered in clusters that are ordered over longitude, the seismicity maxima form long chains of anomalies. It is shown that the mean migration rate of seismicity maxima does not vary throughout the east-west trending Olekma-Stanovoi and the Tukuringra-Dzhagdy seismic zones that travel from the north-south eastern framing of the Amur plate as far as the east-west Tukuringra-Dzhagdy seismic zone. We determined the period of spatial synchronization of seismicity in annual cycles. Considered in the framework of a wave model that is assumed for the dynamics of seismicity, we show that the seismic activity in annual cycles can be initiated due to the modulation of seismicity by an external periodic force loading.

“…Landslide is a serious natural disaster, which often causes huge economic losses, even casualties. 1,2 To monitor landslides, it is necessary to obtain the parameters such as the surface crack displacement and inclination angle of landslide, [3][4][5] especially its internal parameters such as stress and deep displacement, which can better reflect the actual characteristics of the landslide. 6 The emergence of wireless electromagnetic wave communication technologies, such as wireless sensor networks (WSNs) and the Internet of Things (IoT), provides good solutions for ground landslide parameters monitoring.…”

This article introduces a magnetic induction communication transceiver MI-S125-III, which can be buried in a landslide body and can be used to transmit the internal characteristic parameters of landslide mass (such as inclination angle). The device is based on the Manchester code, and the working frequency is 125 kHz. Its data transmission distance can reach 5.28 m in the soil. We built a physical landslide model, in which three MI-S125-III nodes with a tilting sensor were embedded, and the angle monitoring curve was obtained by human triggering. The angle monitoring curve can reflect the sliding process, indicating that MI-S125-III can be used for landslide monitoring and early warning in the future.

Abstract:The interaction between the Amur, Pacific and Eurasian tectonic plates initiates seismic activity at the plate margins as well as in the plate periphery, as evidenced by intracontinental earthquakes. In the Amur plate, the dynamics of intercontinental seismicity is controlled by deformation wave fronts comprising a regular pattern of equidistant zones [Sherman, 2013]. According to [Trofimenko et al., 2015a[Trofimenko et al., , 2015b, maximum values of seismic activity in the range of magnitudes 2≤M≤4 also form a sequence of spatial cells in the form of seismic clusters from the east (Sakhalin -Sakh) to the west (the western boundary of the Baikal rift zone -BRZ ) (Fig. 1). One of the main characteristics of the seismic process is seismic activity migration given as sequential activation of seismogenic structures within the seismically active zones and on the global scale [Vikulin et al., 2012;Khain, Khalilov, 2008]. Direct observations show that crust deformation migrates from the Japan-Kuril-Kamchatka subduction zone towards the continent, and the estimated migration rates range from 10 to 140 km per year (e.g. [Ishii et al., 1978;Kasahara, 1979;Harada et al., 2003;Yoshioka et al., 2015]). In the Baikal and Amur regions (107-140°E), the fronts of deformation waves migrate at a rate of 5-20 km per year [Sherman, 2007[Sherman, , 2013. Considering the order of magnitude, this rate is comparable to the rates of crust deformation migration from the Japan-Kuril-Kamchatka zone (10-100 km per year). Our studies show that the sequential activation of the seismic clusters in the northeastern segment of the Amur plate (Sakh -TanLu -Al-St) occurs at a rate of 1000 km per year [Trofimenko et al., 2015a] (Fig. 1). In the meridional tectonic structures, the shifting chains of maximum seismicity values are sequentially replaced by minimum values (i.e. inversion zones). Based on the spatial cycles with the phase shift of the maximum seismic activity values at the rate of 1000 km per year, it is possible to represent the dynamics of seismicity in the form of a process initiated by long-period stress waves/deformations. According to [Mogi, 1968;Kasahara, 1979;Malamud, Nikolaevskii, 1989;Saprygin et al., 1997;Harada et al., 2003;Bykov, 2005Bykov, , 2014Sherman, 2007Sherman, , 2013Sherman, , 2014Milyukov et al., 2013], slow deformation waves of the global and regional scale are generated at the margins of lithospheric plates. Under this concept, the migration rate of seismic activity and the spatial extent of seismic cycles can be identified as the velocity and length of deformation waves. Using the data on seismicity of the most active region of the Baikal rift zone -the northwestern segment of the Amur plate, we have studied the periodic components of seismicity along the entire northern boundary of the Amur plate. An indirect evidence of the existence of deformation waves is the migration of anomalies of geophysical fields and its correlation with the migration of seismic activity. The space-time anomalies of the magnet...
