摘要
地震破坏性大,地震成因争论大,地震预测一筹莫展。地震成因复杂,按成因分类,大体可分为构造地震与非构造地震两类。构造地震是当前学术界的主流观点。非构造地震种类很多,其中爆炸地震(或隐爆地震)可能是最重要的。爆炸地震理论的核心概念是地下气体爆炸,隐爆角砾岩是爆炸地震的关键证据,隐爆角砾岩(筒)即震源中心。超临界流体转变为气体,气体体积膨胀,进而冲破围岩阻力是导致爆炸的原因。按照构造地震理论,地震是很难预测的,而按照爆炸地震理论,地震是可以预测的。按照构造地震理论,减震防灾是几乎不可能的,而按照爆炸地震理论,浅源地震(<10 km)减震防灾也可能是有办法的。
Earthquakes are highly destructive phenomena,sparking considerable debate in earthquake causes and presenting significant challenges in prediction.The genesis of earthquakes is intricate and is broadly categorized into two principal types:tectonic earthquakes and non-tectonic earthquakes.Tectonic earthquakes represent the dominant perspective in the academic community.Among non-tectonic earthquakes,there are various types.One of the most significant is explosive earthquakes(also known as Cryptoexplosive Earthquake).The key of explosive earthquake theory involves underground gas explosions,with of cryptoexplosive breccia serving as diagnostic evidence for such events.The cryptoexplosive breccia(tube)is considered the Hypocenter.These explosions are triggered by the transformation of supercritical fluids into gases,which,upon expansion,overcome the resistance of the surrounding rock.Tectonic earthquake theory posits that earthquakes are inherently unpredictable,whereas explosive earthquake theory suggests that prediction may be feasible.Aligning with the principles of tectonic earthquake theory,the prediction and effective mitigation of seismic disasters remain a formidable challenge.Conversely,the theory of explosive earthquakes proposes that it may be possible to develop strategies for mitigating and preventing shallow seismic events(<10 km).
