網友的斷句有問題，你可能是把 Sunday off 連在一塊看作固定搭配了，是吧！其實，這里的Sunday 與 off 是分屬兩個意群的，閱讀時可在 Sunday 后面稍作停頓——Sunday 與前面的 around7:00 a.m. 是一個意群，意思是“星期天早上七點”，off the west coast of... 是指“在……西岸附近”。

全段大意：昨天，40年來最為強烈的地震引發了沖擊亞洲沿海地帶的海嘯，導致印度尼西亞、印度、泰國、馬來西亞與至少其他四個國家6500多人死亡。漁民、游客、酒店、住房和汽車都被這次里氏9.0級的強震所引發的巨浪卷走。周日上午7點左右，印尼蘇門答臘島西海岸發生海底地震。僅在那個區域，就有至少1870人喪生。
