摘　　要：通过对2006年5月27日印度尼西亚日惹6.4级地震灾情调查和评估,得出此次地震灾情分布具有以下特征:(1)尽管日惹地震震级较小,但形成的灾害却很严重,地震形成了2个重灾区,即班图尔(Bantul)重灾区和克拉特恩(Klaten)重灾区;(2)建筑物结构不合理、建筑物质量和材质差,建筑物抗震性能差,灾区场地环境不良,加之灾区人口密度大和地震发生在凌晨等,是此次小震大灾的主要原因;(3)对地震构造背景以及与默拉皮火山(Merapi Volcano)相关性进行了初步研究,提出此次地震与火山活动密切相关。Through investigation and disaster assessment of Ms 6.4 Yogyakarta Earthquake of Indonesia happened on May 27, 2006, we find that： 1） even with a relatively small magnitude, this earthquake produces the serious damages in two areas, i.e. Bantul and Klaten. 2） there are several main factors contributing to the severe damages, including unreasonable structure of building, low quality of building materials, inadequate earthquake-resistance ability of structure, high populated areas and earthquake occurring at night time This paper also studies the relationship between tectonic background of the earthquake and Merapi volcano activity, putting forward a close relationship of those two.
