On November 8, 2013, Super Typhoon Yolanda (international name: Haiyan) hit the Philippines. Tacloban, Leyte, and the surrounding shore of San Pedro Bay suffered the most damages. Because of strong winds brought by Yolanda, a 5–7 meter-high storm surge took place. Yolanda, as the storm surge cause, killed more than 6,000 people.
