| 摘 要： | 1605年发生于海南岛北部的琼州大地震,震中烈度Ⅺ,震级73/_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

PRELIMINARY DISCUSSION ON THE 1605 QIONGZHOU EARTHQUAKE AND ITS SEISMOGENETIC STRUCTURE |
| |
| Abstract: | 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 eas |
