摘要
本文从物质分异的角度出发并利用现代小震活动资料,讨论了东南沿海地震带历史大震震源区及其附近,今后一段历史时期内是否有大震(M≥0)震源区大震重复性和大震减震作用问题。结果表明,这些历史震源区目前还处在减震阶段,今后一段时间只能以小震或中强地震的活动特点来显示这一弱化区。
In a material differentiation point of view and from the data of recent small seismic shochs, this paper deals with the recurrence and attenuation of major earthquakes (M≥7) in the focal zones in Southeast China coastal seismic belt. It indicates that these historical focal zones are still in an attenuation stage. These seismic attenuation zones are characterized only by small or moderately strong earthquakes in a relatively long period to come.
