该来的时候就来，平时人们该干嘛干嘛。richmond地势低，都唱了好多年要海啸水淹的歌了，人口继续增加，房价还是飞涨。这种用一旦blablabla字眼的专家文章，就是耍流氓
刚刚从tofino回来，呆了一周，长滩天天大浪，不知道是不是小地震引起的，就是冲浪过瘾

richmond要海啸水淹的歌多来自野鸡新闻吧。
这是city of richmond 网站的官方对海啸风险的描述：
https://www.richmond.ca/safety/prepa...arthquakes.htm
＂Richmond is Not at Significant Risk of Tsunamis
Tsunamis are long, high ocean waves commonly generated by underwater earthquakes. The most recognized source of an underwater earthquake that may cause a tsunami capable of reaching the city of Richmond is from the Cascadia Subduction Zone located in the Pacific Ocean to the west of Vancouver Island. Vancouver Island lies as a kind of breakwater between the Pacific Ocean and Richmond, if a Pacific tsunami was generated it is estimated that waves would dissipate to around 0.5 metres in height as they reach the western shore of the Fraser delta. The City's dikes would adequately mitigate the effects of this type of event.＂
由于温哥华岛的阻隔与缓冲，大地震形成的海啸到richmond时候已经减轻到0.5米高，影响不大。
大温其实不在任何大地震带明显影响范围内，内陆的西雅图断层带(Seattle Fault)根本影响不到大温，海洋底的大地震带由于大温有温哥华岛的天然屏障保护，也对大温影响很小。
