| 摘 要： | 2009年4月6日发生的意大利拉奎拉Mw6.3地震造成了地表的严重破坏,为了解地震引起的地表变化情况,本文利用ALOS/PALSAR影像数据,采用二轨差分干涉测量技术提取了该次地震的地表同震形变场。通过分析可知:地表在西北-东南方向上发生错动,形变主要发生在40×30 km的范围内,西南部出现了沿视线方向的下降,东北部出现了沿视线方向的抬升,最大值分别为0.337 m和0.122 m。结果表明,获得的同震形变场与地震地质调查的结果一致。 |

| Abstract: | The Mw6.3 L＇Aquila earthquake that occurred on 6 April 2009 caused serious surface damage.To measure the ground deformation induced by the earthquake,this paper use the ALOS/PALSAR data and the Two-Pass differential interferometry to estimate the co-seismic deformation.The analysis show that the ground surface dislocated along the Northwest and Southeast direction,mainly within an area of 40×30 km,while in the Southwest and Northeast part significant subsidence and uplift occurred,with the maximum of 0.337 and 0.122 m.The results are consistent with that from geological investigation. |
| Keywords: | DInSAR L'Aquila earthquake PALSAR co-seismic deformation |
