A massive surge of water from the Yom River, originating from Wang Chin district in Phrae province, has inundated homes in the northern districts of Sukhothai.
Flood barriers collapsed at multiple points on August 26.
Aerial images reveal numerous breaches in the dikes and riverbanks, allowing the Yom River, with its water level at 11 meters, to inundate the area with tremendous force.
Flash floods and mudslides across Thailand brought by monsoon rains have killed 22 people and injured 19, authorities said on Monday.
Severe flooding persists in five northern provinces, such as Chiang Rai, Sukhothai and Prae, while there is a high risk of waters rising in areas near the Chao Phraya River, including the capital, Bangkok, though levels are still manageable.
