我这样形容这次的大灾难，它在缅甸的历史上是空前的，而且带来的影响与之前几个受海啸破坏的个别国家相当。

I'd characterise it as unprecedented in the history of Myanmar and on an order of magnitude with the effect of the tsunami on individual countries.

纵观海啸预警系统的历史，其警报纯粹是建立在地震信息的基础之上，譬如对震级、位置和深度的估计。

Throughout most of the history of the tsunami warning system, the warnings were based purely on the earthquake information-our best guess for the magnitude, location and depth.

当看到此次灾难的新闻时，纽蒙正在研究日本过去的海啸。看新闻时，她的心直往下沉：长远的历史，充斥着一个个灾难。

Newman dug in to research studies of Japan's past traumas as she watched news of the disaster, and what she saw heartened her: a long history of reaching out to one another in times of loss.
