National Floods

There were fourteen international floods reported across nine countries throughout September 2018. At least 1,628 people died and over 4.2 million people were displaced.

Internationally significant floods included:


At least 1,400 are recorded dead and 61,000 displaced after an earthquake and tsunami hit Indonesia. The tsunami which completely engulfed the island city of Palu was caused by a 7.5-magnitude earthquake which occurred near the Province of Sulawesi in central Indonesia. More than 66,000 homes were destroyed or damaged by the quake and subsequent tsunami. The disaster has caused widespread inaccessibility to essential resources such as food, clean drinking water and fuel. Survivors are struggling to find basic resources even with disaster relief being provided to the afflicted city (read more hereherehere and here).


At least 35 people have died and more than 150,000 displaced after historic rains and flooding caused by Hurricane Florence swept through the Carolinas and Virginia.  In the North Carolina city of Swanboro, more than 900 mm of rain was recorded, and 600 mm in the South Carolina city of Loris. Several rivers in North Carolina reached record levels, causing flash flooding in coastal towns such as New Bern, Belhaven and Morehead City. It was recorded on 15 September that nearly 20,000 people were housed in more than 150 shelters across North Carolina. Roads and power supplies were also cut off with approximately 800,000 people without power in North Carolina (read more hereherehereherehere and here).

North Korea

At least 76 people have died and 58,000 displaced as heavy rains and floods hit parts of North Korea. Low lying areas of the Kangwon and South Hamgyong provinces experienced severe flooding after Tropical Storm Soulik brought heavy rainfall to the region from late August. This comes after a period of drought in the region. The city of Munchon located in the Kangwon province was the most severely affected. The city’s water supply system was destroyed which left tens of thousands of people without access to safe drinking water. In addition, 10,000 houses have been destroyed throughout the country as a result of the floods (read more here and here).


More than 200 people have died and 176,000 displaced due to heavy rain and flash flooding in the states of Jigawa, Niger, Kano and Nasarawa. Heavy rains caused the Niger River and Benue River to overflow resulting in flash flooding. The impact of the flooding was perhaps worsened by the lack of proper town planning, blocked waterways and poor drainage systems. The floods swept away homes and destroyed vast areas of farmland (read more here and here).

Philippines and China

Flooding and landslides caused by Typhoon Mangkhut has resulted in the deaths of 70 people and the displacement of 2.5 million spread across the Philippines and China. The category five typhoon swept through the Philippines, bringing with it soaring wind speeds of 200 km/h, flooding and landslides. The majority of fatalities were in the Philippines. The Philippine island of Luzon was badly affected by the typhoon as vast areas of key agricultural crops such as rice and corn were destroyed. The typhoon then moved up into southern China’s Guangdong province which led to the mass evacuation of 2.4 million people. Transportation within the region was also largely cut off due to the flood waters (read more herehere and here).
