The fear of Tsunami

When I went to help clear sludge around the house, I heard a story of that house owner's wife. The day of Tsunami was happened, he and his daughter weren't at home. When Tsunami occurred, mom was at home alone and failed to escape. The water level was up to 2m, so she held on a beam of her house. After that water level was up to 3m, she caught tatami and held on it for 2 hours. It was very cold and snowy. Rubbles, broken cars and house pieces attacked on the pillar and broke them. But she was lucky not to be hit by rubbles. If the rubbles hit her.... Can you image her fear and suffering? And we also know that there were lots of victims like her, and most of them died...
