After super typhoon Yolanda (Haiyan), people in Tacloban had to find shelter wherever they could. Many people moved into the spaces under and around the new fish market building. As far as I understand the history, this entire area used to consist of squatter housing. Then the people who lived there were moved out to make room for this new fish market. With their homes destroyed and the market also damaged and not functioning, people now moved back into the market area.
