倒楔运动引起地震的原因分析
|
摘要
在"两堑夹一垒"楔块运动系统中,由于倒楔的运动能导致其质量变小,惯性变小,容易变动;长宽比大,横向薄弱,容易断裂;底面积大,岩浆富集,容易隐爆等原因,所以能引起地震,这是倒楔运动与地震带相关联的原因所在.
It′s considered that the movement of inverted wedge block in the graben-horst structure might cause the earth-quake because of the following reasons: The movements of inverted wedge block would lead it easier to change for its quality and inertial decreased;The movements would lead the inverted wedge block easier to fracture on account of its length to width ratio increased;It could also made the wedge block easier to explosion because of the base area enlarged and the enrichment of magma.This is the reason that the inverted wedge blocks have relations with the seismic belt.
