## 1 Introduction  
The development of the Arctic zone of the Russian Federation (AZRF) is an important area of economic and scientific progress for the country. This is determined, first of all, by the significant reserves of minerals in the Russian Arctic. Today, the region produces oil (80% of the total volume in the country), natural gas (93%), nickel and copper (90%), diamonds and gold (33%), platinum, palladium, cobalt, tin, manganese, coal, etc. [1]. The relevance of scientific research in the Russian Arctic is growing due to climate change caused by global warming and the accelerated melting of Arctic ice [2; 3; 4; 5]. Assessment of the hazards of geodynamical nature plays a significant role in determining the strategy for the industrial development of promising regions, which undoubtedly includes the Russian Arctic [6]. The central role here belongs to seismic hazard, which is taken into account both in determining urban planning policy and in planning industrial and infrastructure network facilities. In this paper, the area of seismic hazard assessment is the eastern sector of the Russian Arctic. In its oceanic part, the Eurasian basin, the Gakkel Ridge, and the Canadian basin can be identified. They are divided by the Lomonosov and the Alfa-Mendeleev Ridges, which are separated from each other by the Makarov Basin and the small Mendeleev abyssal plain. The continental part is represented by accretion-collision structures. Among them is the Verkhoyansk Range, which frames the Siberian platform from the east. This is followed by is the Chersky Range. Further to the east, there is a series of arched ranges of Koryakia and Chukotka [7; 8] (Figure 1). Seismogenic zones in the continental part are represented by the boundary between the North American and Eurasian plates (Figure 1). The latter consists of several structures extending from the Laptev Sea and the mouth of the river Lena to the coast of Okhotsk and the Isthmus of Kamchatka. The transverse extent of seismogenic structures exceeds 1000 km. Some researchers distinguish here a collage of microplates, including the Amur, Okhotsk, and Bering plates [9]. Some authors trace here several seismogenic structures, including the Laptev Sea, Kharaulakh, Cherskiy seismotectonic zones, and the Arctic-Asian seismic belt [8,10]. Over the past two decades, a number of strong earthquakes with a magnitude \(M\geq 6.0\) have occurred in the studied region (Figure 2). Among them is the Olyutorsk earthquake on 20.04.2006 with \(M=7.6\); the earthquake on 24.06.2012 near the northeastern coast of the Kamchatka Peninsula with \(M=6.0\); two earthquakes with \(M=6.5\) and \(M=6.3\) that occurred consecutively on 30.04.2010 in the Bering Sea; Ilin-Tas (Abyi) earthquake on 14 February 2013 with \(M=6.6\); earthquake on 09.01.2020 with \(M=6.4\) near the border of Kamchatka and Chukotka [11,12,13,14], and others (Figures 1 and 2). Sufficiently detailed information about strong earthquakes in the Russian Arctic that occurred before the mid-1970s can be found in [15]. The foregoing emphasizes the existing high seismic hazard of the region and substantiates the urgency of the problem of determining areas in the eastern sector of the Arctic zone of the Russian Federation within which strong earthquakes can occur. Figure 1: The main structures of the eastern sector of the Russian Arctic. The yellow line is the boundaries of tectonic plates, the light green dotted line is the polar circle, and the red stars are the epicenters of earthquakes with \(M\geq 6.0\) that occurred over the past two decades. The white frame shows the boundaries of the studied region. A large number of scientific papers are devoted to the analysis of the seismic regime of the Arctic zone of Russia and the construction of corresponding seismic hazard maps (see, for example, [17; 18; 19; 20; 21], and others). Here it is necessary to note the systematically updated set of maps of the General Seismic Zoning (GSZ) [22; 23; 24; 25; 26] on the scale of the whole of Russia.
