巴东地震 （视频）
印尼苏门答腊岛周四才发生7.8级地震，周五早上再发生7级强烈地震。
大地震已导致主要城市巴东（Padang）通讯中断，丧命者可能超过千人，数以千计灾民受困在瓦砾中。印尼副总统尤索卡拉在记者会上说，有可能1000人在地震中丧命。由于许多建筑物包括酒店、医院、学校和商店坍塌，他相信死亡人数还会上升。印尼专家表示，这次地震应是9月30日7.9级地震的余震。震区有几个人口稠密的城镇，但目前还没有伤亡报告。
印尼政府已在灾区启动了为期2个月的紧急状态。

The tapwater in all these areas is considered soft as the hardnesslevel is below 100 mg CaCO3/L. Although there is nohealth-based guideline value, soft water and low pH maycause corrosion of pipes result
