На геофизическом семинаре ИНГГ СО РАН выступил ведущий эксперт лаборатории методов интерпретационной обработки сейсмических данных д.ф.-м.н. Борис Петрович Сибиряков. Также в подготовке презентации принял участие старший научный сотрудник лаборатории вычислительной физики горных пород д.ф.-м.н. Егор Борисович Сибиряков.

Доклад был посвящён природе землетрясений, дискретности сейсмических явлений и аномально низким скоростям волновых процессов в трещиновато-пористых геологических мегаструктурах.

– Катастрофы разного масштаба являются естественным состоянием микро- и мега структурных сред. При этом переход от одного состояния к другому может быть только дискретным (отдельные удары). Это подтверждают и натурные опыты, и сейсмологические наблюдения (афтершоки), – отметил Б.П. Сибиряков.
По словам эксперта, наблюдения периодов афтершоков позволяют оценить удельную поверхность не наблюдаемых трещин или среднее расстояние между трещинами, если скорости обычных упругих волн в среде известны. Как подчеркнул Борис Петрович, безопасность обеспечивается единичной дисперсией расстояний между трещинами.
– И уменьшение дисперсии (самоорганизация среды) и её чрезмерное увеличение ведут к катастрофам совершенно различного рода, – заключил специалист.
В обсуждении доклада приняли участие д.ф.-м.н. В.Ю. Тимофеев, к.г.-м.н. П.Г. Дядьков, к.ф.-м.н. А.А. Дучков, д.ф.-м.н. В.А. Чеверда, д.г.-м.н. Е.В. Деев, д.г.-м.н. В.Д. Суворов, к.ф.-м.н. С.С. Абраменков. В дальнейшем в ИНГГ СО РАН продолжат развивать озвученные Б.П. Сибиряковым тезисы и концепции.
