Near Islands Aleutian Earthquake with MW = 7.8 on July 17, 2017: I. Extended Rupture along the Commander Block of the Aleutian Island Arc from Observations in Kamchatka

Variability in the Statistical Properties of Continuous Seismic Records on a Network of Stations and Strong Earthquakes: A Case Study from the Kamchatka Peninsula, 2011–2021

“…The Near Islands Aleutian earthquake (No. 3 in Table 3), with a rupture length of 500 km [23], occurred on July 17, 2017, also in the "dangerous" range of latitudes 54-58 N.…”

“…Using this approach, the features of the spatiotemporal distribution and coherent behavior of seismic noise statistics were found in connection with the preparation of local earthquakes with magnitudes of 7-8. 1), earthquake epicenters with Mw = 7.2-8.3, and tectonic plate boundaries: 1-seismic stations with codes indicated: blue designates coastal stations, and white designates continental stations; 2-earthquake epicenters; 3-areas of earthquake sources according to [20][21][22][23][24]; 4-boundaries of the northern, central, and southern groups of stations (from top to bottom); 5northwestern and northeastern boundaries of the considered area of the Pacific Oceanic Plate (PA); 6-boundary of the North American continental plate (NA) with PA and small lithospheric plates Beringia (BE) and Okhotsk (OK) [25,26]. White arrows indicate the direction of PA movement; numbers-the speed of TO movement [27].…”

Global Induced Stress Field From Large Earthquakes Since 1900 and Chained Earthquake Occurrence

“…Large earthquakes over the previous 100 years lowered the stress levels over most regions along the Japan Trench and Nankai Trough. There are seismic gaps in the eastern Nankai Trough, northern Kuril Trench, and western Aleutian Trench, such as the Commander gap and Tokai gap (Chebrov et al., 2019; Geller, 2011; MacInnes et al., 2016) (Figure 23).…”
