Typhoon Lionrock

Infrares satellite loop of Lionrock making landfall in Tōhoku region on August 30

Upon making landfall on August 30, Lionrock brought very heavy rainfall, including 13.46 inches (342 mm) at Mount Nukabira, in Hokkaidō Prefecture, and 8.78 inches (223 mm) in Orito in Iwate Prefecture. In addition, a maximum wind gust of 69 mph (111 km/h) was recorded in Ishinomaki, and a 66 mph (106 km/h) wind gust was measured in Onagawa.[12] Lionrock killed a total of 22 people across Japan, including 19 people in the town of Iwaizumi in Iwate Prefecture.[18] Nine people drowned in a nursing home in Iwaizumi after a river burst its banks. In addition, there were at least three fatalities on the northern Japanese island Hokkaidō.[19] Damage due to flooding were standing at JP¥282 billion (US$2.74 billion).[20]

On 31 August, the storm hit Primorsky Krai. Heavy rainfall caused floods in several areas with 300 houses flooded in rural areas. Local rivers overflowed, several bridges were destroyed or damaged and several highways were affected by floods. A dam failure along the Pavlovka river caused floods in the Shumny and Antonovka villages. More than 1,000 inhabitants were evacuated and several evacuation camps were established in all affected areas, mostly in schools.[21] The storm also caused power disruptions.[22] 12,000 rescue workers were also deployed in the area.[23]

The southern part of the Sakhalin was also affected. Several cars were struck by fallen trees and electricity was shut down in some houses. Heavy rain flooded Makarovsky and caused a landslide which blocked a highway and a railway. Two trains on the Yuzhno-Sakhalinsk-Nogliki line were cancelled and one of them, No. 604, was stopped in Poronaysk.[24] In Vakhrushev, one of the cargo trains derailed. Hours later, the incident was fixed and its operations returned to normal. However, one fatality was reported during the incident.[25] In addition, two EMERCOM officers (the chief of the Primorsky Krai department and his driver) died when their KAMAZ truck fell into the Pavlovka River.[26] Lionrock was the worst typhoon to hit the Primorsky Krai region in 40 years, with total damage exceeds ₽7 billion (US$107 million).[27]

A total of 464,900 ha (1,149,000 acres) of agricultural land were impacted in China, including 53,500 hectares (132,000 acres) of crops which were destroyed due to floods. Damages in China are estimated to be CN¥7.21 billion (US$1.08 billion); most of which was inflicted on the agricultural sector.[28]

The extratropical remnants of Lionrock over Northeast China and Russia on August 31

Lionrock interacted with a low pressure area over China to drop heavy rainfall in North Korea, mostly in North Hamgyong Province,[16] considered by the state media Korean Central News Agency to be the "heaviest downpour since 1945".[29] Over a two-day period, Kyonghung County recorded 320 mm (13 in) of rainfall. This caused flooding along the Tumen River and its tributaries,[16] inundating about 16,000 ha (40,000 acres) of farmlands just weeks ahead of the harvest,[30] of which 10,145 ha (25,070 acres) were wrecked.[16]

The floods from Lionrock caused "a disaster beyond anything experienced by local officials", according to a local UNICEF representative, and were described as "a very major and complex disaster" by Chris Staines, head of the Red Cross Society of the Democratic People's Republic of Korea.[30] The affected area had poor infrastructure and deforestation on hills, exasperating the floods' impacts.[31] Entire villages were washed away, carrying away families' entire possessions.[32] Three people trapped in floodwaters were rescued by two Chinese rescue boats.[33] Over 35,500 houses were damaged, of which around 25,000 were destroyed,[34] forcing 107,000 people from their homes;[31] many of these people sheltered on higher grounds or in public buildings.[16] Floods from Lionrock damaged another 8,700 non-residential buildings, including schools and public buildings.[34] In Ryanggang Province, the heavy rains caused a five-story building to collapse, killing 34 people.[17] In Hoeryong city, over 104,000 people lost access to clean water during the floods, and nationwide about 600,000 people were affected by water cuts. Musan and Yonsa counties were unreachable and had little communications, resulting in the slow spread of information on the disaster.[30] The floods also washed away six bridges and 31 km (19 mi) of roads, with 43 km (27 mi) of road bed damaged.[16] The floods related to Lionrock killed at least 525 people in the country.[35][30]

After the floods, the North Korean government sent workers to clear roads and restore communications in the hardest hit areas.[30] The government sent a truck from the capital Pyongyang with medical kits and vitamin supplements on September 5,[31] and announced a plan to rebuild 20,000 houses by early October 2016.[34] The Central Committee of the Workers' Party of Korea requested that party members redirected their efforts from a 200-day mass worker program intended to improve the economy, and instead send soldiers to help with flood relief.[29][36] About 1,000 volunteers from the country's Red Cross chapter helped local workers in search and rescue missions. The agency had relief supplies for about 20,000 people, including tarpaulins, tents, kitchen sets, and water purification tablets.[30] Red Cross workers coordinated with members of the international delegation between September 3–6, resulting in increased resources for health services.[16] The local Red Cross launched an appeal for emergency aid in response to the disaster through the state media Korean Central News Agency.[37] The government, which rarely releases information on disasters in the country, requested for aid from the international community, just days after a nuclear weapons test that led to calls for increased sanctions.[29] The World Food Programme provided emergency food rations for 140,000 people in need of immediate assistance.[32]
