The new seismometers used were sensitive to seismic waves with periods from 0 . 03 to 1 second . the precision of epicentre determination was improved to within 10 kilometres and ground motions down to one nanometre could also be detected 03秒至1秒的震动最为灵敏，震央定位精确度提升至十公里以内，并可以测量振幅小至一纳米的地壳震动。
At the same time , the hong kong observatory also began to keep a record of locally felt tremors reported by the people of hong kong . the seismometer used was of the long - period type , sensitive to seismic waves with periods around 15 seconds and was suitable for detecting distant earthquakes 天文台总部使用的地震仪属于长周期地震仪，对震动周期约15秒的震动最敏感，适合监测远处发生的地震，结合其他国家的地震站数据可以测定强烈地震的震央位置。
The southwest coast of sumatra , indonesia , was rocked by an 8 . 4 magnitude earthquake on wednesday night , and a 7 . 8 - magnitude tremor thursday morning . the quakes , centered near the coastal cities of bengkulu and padang , prompted tsunami warnings , and sent thousands of people fleeing from their homes in fear 印尼苏门答腊岛西南岸周三晚上发生规模8 . 4的地震，周四早上再度发生规模7 . 8的地震，地震震央接近明古鲁市及巴东市外海附近，也发布海啸警报。
Athens on september 7th at 2 : 56 p . m . local time , a strong earthquake of magnitude 5 . 9 on the richter scale occurred in the north of athens , the capital city of greece . the center of the earthquake was in the north suburban area of athens . this was the most severe earthquake to occur in athens in decades , causing injury and death to more than five hundred people , destroying many buildings and leaving thousands of people homeless 希腊首都雅典北部9月7日在当地时间下午二时五十六分左右发生芮氏规模五点九级的强烈地震，震央位于雅典北部郊区，这是雅典数十年来最严重的地震，至少造成五百多人伤亡及许多建筑被毁，导致几千人无家可归。
