According to our estimates, 90% of the energy is released relatively close to the Earth's surface, at the average depth of 50 km. The bulk of the remaining 10% is associated with seismic events that take place at large depths, on average 630-640 km above the boundary between the transition zone and lower mantle. These very deep earthquakes (depth >= 350 km) significantly differ from the shallow events. Their sources, in contrast to the shallow focus events, are located inside the plate. The examination of seven seismic zones described in the present study, except for the Honsu-Kamchatka zone which accommodates both the shallow and deep M >= 7.0 earthquakes, shows that the linear distribution of the hypocenters of deep earthquakes is considerably shorter than that of the shallow earthquakes, which, in turn, determines the length of the seismic zones at depth. In the zones of the Solomon Islands and the Izu-Bonin-Mariana arc, there are no seismic events with M >= 7.0 deeper than 450 km. In the zones of Indonesia, Philippines, Tonga-Kermadec, and Chile-Peru, the mentioned length's shortening at the top of the lower mantle (660-km discontinuity) relative to the length of the zone observed close to the surface is unequivocal. The relationship between the lithospheric plates is supported by the spatial distribution of the hypocenters. The position of the foci of very deep (>= 500 km) earthquakes indicates where the descending lithospheric plates conflict with the upper boundary of the lower mantle, and where in some cases they cross it. This passage generates the compression and elongation inside the slab. A comparison of the time distribution of the shallow and deep seismic events suggests the absence of direct relationship between these two different earthquake activities. For studying the fairly uncommon deep earthquakes, important additional information was provided by the largest of the deep earthquakes, the May 24, 2013 M 8.3 event beneath the Sea of Okhotsk, in an area where significant deep earthquakes have already occurred. Based on our studies of the records provided by the Russian and Hungarian national seismological networks, we concluded that this seismic event was preceded by an earthquake swarm, which consisted of 58 M >= 5 events between May 15 and 24, 2013 in the higher part of the sinking slab east of Kamchatka within the segment of increased historical seismicity. Most probably, the interaction of two distinct active source zones took place. The aftershock activity beneath the Sea of Okhotsk was moderate: thirteen events with magnitudes above De >= 4.0 were observed by June 27, 2013. Nevertheless, the unusually small number of aftershocks determined a fault area (2.64 x 10(4) km(2)), generally similar to that in the case of the assumed shallow M 8.3 event. 2017 262475 true true true false true false RESTRICTED 2026-09-18 false 5 0 5 3 1 5 5 5 5 5 5 3 3 3 2 0 5 3 5 3 0 1 1 Folyóiratcikk Journal Article 24 4 Könyvrészlet Chapter in Book 25 1 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2018 0 3 2 3 2 2019 0 1 1 1 1 2020 0 0 0 0 0 2021 0 1 0 1 0 Q2 false false false false 2017-09-20T13:30:10.000+0000 2017-09-19T11:29:45.000+0000 Geodéziai és Geofizikai Intézet (CSFK) 2 7 1 4 0 true Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 9339676 /api/authorship/9339676 Varga, P [Varga, Péter (Geodézia és geofi...), szerző] Geodéziai és Geofizikai Intézet (CSFK) 1 0.25 true false Author 10001283 /api/author/10001283 Varga Péter (Geodézia és geofizika) Varga Péter true 10001283 true Varga P true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 26832669 true PersonAuthorship 9339677 /api/authorship/9339677 Rogozhin, EA 2 0.25 false false Rogozhin EA true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 26832668 true PersonAuthorship 9339678 /api/authorship/9339678 Sule, B [Süle, Bálint (Szeizmológia), szerző] Geodéziai és Geofizikai Intézet (CSFK) 3 0.25 false false Author 10017053 /api/author/10017053 Süle Bálint (Szeizmológia) Süle Bálint true 10017053 true Sule B true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 26832667 true PersonAuthorship 9339679 /api/authorship/9339679 Andreeva, NV 4 0.25 false true Andreeva NV true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 26832666 true PublicationIdentifier 1228263 /api/publicationidentifier/1228263 DOI: 10.1134/S1069351317030132 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true false IDENTICAL 10.1134/S1069351317030132 https://doi.org/10.1134/S1069351317030132 false 1638252 true PublicationIdentifier 1228264 /api/publicationidentifier/1228264 REAL: 63152 SwordSource 36 /api/publicationsource/36 REAL PublicationSourceType 10007 /api/publicationsourcetype/10007 Repozitórium true true true REAL REAL https://real.mtak.hu/@@@ true true 36 true RESTRICTED false NO 63152 https://real.mtak.hu/63152 false 1638861 true PublicationIdentifier 1228261 /api/publicationidentifier/1228261 WoS: 000402183400006 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true false IDENTICAL 000402183400006 https://www.webofscience.com/wos/woscc/full-record/000402183400006 false 1638251 true PublicationIdentifier 1228262 /api/publicationidentifier/1228262 Scopus: 85019728403 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true false IDENTICAL 85019728403 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85019728403 false 1638262 true Classification 10399 /api/classification/10399 Föld- és kapcsolódó környezettudományok true true Keyword 838 /api/keyword/838 TEMPERATURE true 838 true Keyword 1001132 /api/keyword/1001132 CONSTRAINTS true 1001132 true Keyword 1003006 /api/keyword/1003006 transition zone true 1003006 true Keyword 1007947 /api/keyword/1007947 AFTERSHOCKS true 1007947 true Keyword 1010075 /api/keyword/1010075 lithosphere true 1010075 true Keyword 1041458 /api/keyword/1041458 DEPTH true 1041458 true Keyword 1117793 /api/keyword/1117793 focal depth true 1117793 true Keyword 1126466 /api/keyword/1126466 BENEATH true 1126466 true Keyword 1218146 /api/keyword/1218146 Sea of Okhotsk true 1218146 true Keyword 1399705 /api/keyword/1399705 Slabs true 1399705 true Keyword 1454983 /api/keyword/1454983 earthquake swarm true 1454983 true Keyword 1454985 /api/keyword/1454985 earthquake catalog true 1454985 true Keyword 1454986 /api/keyword/1454986 shallow and deep earthquakes true 1454986 true SjrRating 10692486 /api/sjrrating/10692486 sjr:Q2 (2017) Scopus -
