The destructive Qiongzhou earthquake (July, 13, 1605) which occurred in the northern part of Hainan Island is historically an event having the most severe damage in South China, and causing the land-collapse on a large scale to form a part of the sea. The present investigation gives its intensity as XI, M = 73/4- 8, h=22km± , epicenter location as N19°59', E110°28'.

The destructive Qiongzhou earthquake (July, 13, 1605) which occurred in the northern part of Hainan Island is historically an event having the most severe damage in South China, and causing the land-collapse on a large scale to form a part of the sea. The present investigation gives its intensity as XI, M = 73/4- 8, h=22km± , epicenter location as N19°59', E110°28'. The magistoseismic area is shaped like a partly inverted tablespoon with its main long axis trending NEE, but being intersected east of Mt. Qiongshan by another long axis running NNW. The principal seismogenerating fault is in NEE direction and a NNW-trending fault is across it.This earthquake took place in a tectonic junction between two sets of horsts and grabens, namely, between the NEE trending strongly uplifted Fushan-Meiting horst and the intensely depressed Str. Qiongzhou graben in N. Qiongzhou district, and in NE Qiongzhou between the NNW running -strongly uplifted Yunlong horst and the intensely depressed Dongzhai Harbour graben. It happened in a horizontal stress field with predominantly NW strike (300°±) but resulted from the strongly differential vertical move-ment in the earth's crust In short, this earthquake was induced probably by a pair of X-shaped NEE (predominantly) and NNW-running shearing faults and was the consequence of their growth, development and displacement.

1605年发生于海南岛北部的琼州大地震,震中烈度Ⅺ,震级7~3/_4—8级。极震区强烈下陷,大片陆地沉没为海。极震区长轴方向为北东东,东端向东南偏转为南南东向。该地震是在主压应力轴约为北西300°方向的水平应力场作用下,发生于强烈上升与强烈下降的现代地垒与地堑的边缘转折地带。发震断裂可能为一对X型的北东东向和北北西(以前者为主)的高角度平推正断层。

This work deals with the structure of crust and upper mantle as revealed by an experimental study along the Kangzhuang-Dachang ( 康庄一大厂) profile near Peking, China by observing converted seismic waves of earthquakes. Layered and faulted block structures are indicated. By analyzing and comparing the superficial and deeper structural features of the region, it can be found that a nearly NWW-SBB oriented strong horizontal stress field has been in action within the crust and thus given rise to the up- and downwarping structural units of the region.Hypocentral distributions of earthquakes in this region may be that west of the Gaoliying(高丽营) fault, most of the earthquake foci are located on the top and bottom surfaces of the so-called granitic layer, while east of the Gaoliying fault, they are mostly on the fault belt itself.

Fault-plane solutions of the mainshock and 17 large aftershocks are computed on the DJS-6 computer from the data of the first motions of P waves. Based on the model of finite moving source, the fracture processes and the source parameters of the mainshock and three largest aftershocks are estimated. The Mainshock occurred on a nearly vertical right-lateral strike-slip fault, striking N 30°E, with an asymmetric bilateral fracture which propagated 70 km northeastward and 45 km southwestward with an average velocity...

Fault-plane solutions of the mainshock and 17 large aftershocks are computed on the DJS-6 computer from the data of the first motions of P waves. Based on the model of finite moving source, the fracture processes and the source parameters of the mainshock and three largest aftershocks are estimated. The Mainshock occurred on a nearly vertical right-lateral strike-slip fault, striking N 30°E, with an asymmetric bilateral fracture which propagated 70 km northeastward and 45 km southwestward with an average velocity of 2.7 km/sec. Source parameters of the mainshock such as the average dislocation, seismic moment and stress-drop are estimated to be 136 cm, 1.24×1027 dyne, cm and 12 bars respectively.Most of the aftershocks with ML > 5.0 occurred near the main fault plane and along the fracture branches at both of its ends. These fracture branches are located in the dilatational quarters and make about 80° angles with the mam fault plane. On the two fracture branches, most of the major aftershocks are concentrated. A mechanical analysis of this phenomenon of fracture propagation is attempted in this paper.It is shown that for complex deformations, the fracture propagation no longer takes place along the original plane for brittle materials but deviates from it by a certain angle. The mechanical model used to calculate this deviation angle of fault yields results which agree essentially with the observation.Based on the above results, it can be inferred that the characteristics and mechanical conditions of the Tangshan earthquake as well as those of the Haicheng earthquake are quite different from those of the earthquakes occurring on some great faults which may be explained by stick-slip mechanisms. These two earthquakes are not only caused by the horizontal stress fields but also by local vertical forces induced from the movement of the underground materials. It is also worthy of note that Tangshan earthquake is different from Haicheng earthquake in that it occurs in a relatively homogeneous and brittle medium and therefore no foreshocks took place before the mainshock.
