6.4 magnitude earthquake hits Taiwan
https://www.youtube.com/watch?v=6ZkbQypCqq4 0:33 well as many of you know the south coast of BC is actually part of the Cascadia subduction zone. this is where the Pacific tectonic plate, the Juan de Fuca Plate is actually trying to subduct or move underneath the North American Plate, the one we sit on. and the force of that movement is actually pushing Vancouver Island back towards the mainland only at a rate of about 7mm per year. 皆さんがよくご存知のように、ブリティッシュコロンビア州の南部はカスケード沈み込み帯に属し、ここではファンデフカプレートがわれわれの住んでいる北米プレートの下へ沈み込み、その力によってバンクーバー島は毎年七ミリのスピードで北米大陸に押されて移動しています。
