Analysis of Dynamic Setting about Changbaishan Tianchi Volcano Future Eruption

Abstract:

Article Preview

Dynamic setting analysis of Tianchi Volcano future eruption is discussed by combining the analysis result of focal mechanism with that of structural geology. Analyzing anatectic earthquake focal mechanism shows that subduction of West Pacific Plate to the northeast of China makes the Tianchi Volcano region appear to press west-eastward. And analyzing focal mechanism of near-surface foci earthquake tells us that in the region, direction of the axis of the largest principal compression stress is NEE. The research result of structural geology displays that NWW faults around Tianchi is very active since Epipleistocene. Tianchi Volcano future eruption can be controlled by subduction of West Pacific Plate and strike-slip faulting along the NWW. In the end, the dynamic setting of Tianchi Volcano future eruption is put forward.
