dc.description.abstractСистематизовано параметри та механізми вогнищ сучасних землетрусів у регіоні Східної Балтії. Переважають такі типи механізмів вогнищ материкових землетрусів, як Strike-slip і Reverse. Створено узагальнену карту орієнтації максимальних горизонтальних напружень у Східно-Балтійському регіоні та на прилеглих територіях. Щоб створити цю карту, ми використали базу даних World Stress Map і додали напрямки максимальних горизонтальних напружень в Естонії. Напрямок максимальних горизонтальних напружень змінюється із півночі (Естонія) на південь (Калінінградська область РФ) від 102º–114º до 157º–166º. Ми дослідили, як глибинна геологічна структура та гравітаційні сили в різних частинах земної кори впливають на напрямок максимальних горизонтальних напружень. З’ясовано, що напрямок максимального горизонтального напруження змінювався під час перетину лише одного глибокого тектонічного розлому. Виявлено високі значення кореляції напрямку максимального горизонтального напруження із гравітаційним впливом осадового чохла (від’ємну кореляцію), усередненим різницевим гравітаційним полем і гравітаційним впливом шару земної кори до границі Конрада.
dc.description.abstractThe parameters and mechanisms of the source of modern earthquakes in the Eastern Baltic region are systematized. The predominant types of focal mechanisms of continental earthquakes are strike-slip and reverse. A generalized map of the orientation of maximum horizontal stresses in the East Baltic region and adjacent territories has been created. To create this map, we utilized the World Stress Map database and added the directions of maximum horizontal stresses in Estonia. The direction of maximum horizontal stresses changes from north (Estonia) to south (Kaliningrad region of Russian Federation) from 102º–114º to 157º–166º. The study investigated how the deep geological structure and gravitational forces in different parts of the earth's crust affect the direction of maximum horizontal stresses. It was observed that the direction of maximum horizontal stress changed when crossing only one of a deep tectonic fault. The direction of maximum horizontal stress showed the high correlation values with the gravitational effect of the sedimentary cover (negative correlation), the averaged difference gravitational field, and the gravitational effect of the crustal layer up to the Conrad boundary.
