Typhoon Lionrock (2016)
Typhoon Lionrock, known in the Philippines as Typhoon Dindo, was a large, powerful, long-lived and erratic tropical cyclone which caused significant flooding and casualties in North Korea and Japan in late August 2016. It was the tenth named storm and was the third typhoon of the annual Pacific typhoon season. Damages recorded after the season were recorded about US$3.93 billion.
Meteorological history
The system that was to become Typhoon Lionrock was first noted as a hybrid disturbance on August 15, while it was located about to the west of Wake Island. At this time the disturbance had a broad and poorly organized low level circulation centre, which had some shallow bands of atmospheric convection wrapping loosely around it. It was located within a marginal environment for further development and was predicted to develop further, in association with a developing upper level low. Over the next day the system moved northwards, while a TUTT Cell created subsidence and high vertical windshear over the system, before it was classified as a tropical depression by the Japan Meteorological Agency during August 16. The depression was subsequently classified as subtropical by the United States Joint Typhoon Warning Center during August 17, as its structure was asymmetric, with deep convection displaced to the north and east of the system's low level circulation centre.Lionrock entered the Philippine Area of Responsibility on August 25, 2016, and PAGASA assigned Dindo as the local name for Lionrock. On August 29, Lionrock turned towards the northwest due to a high pressure system located east of Japan, putting it on an unprecedented path towards the northeastern region of the country. Right before weakening into a severe tropical storm at 18:00 JST on August 30, Lionrock made landfall near Ōfunato, a city in Iwate Prefecture, Japan with winds of 75 mph. This makes Lionrock the first tropical cyclone to make landfall over the Pacific coast of the Tōhoku region of Japan since the Japan Meteorological Agency began record-keeping in 1951.
Lionrock's track was unusual due to the fact that the storm approached Japan from the southeast and made landfall along the east coast of the country. Most typhoons that hit Japan approach from the south or the southwest before moving northward across the archipelago. In fact, the only other storm to take a similar track was Typhoon Mac in 1989, which also approached from the southeast and struck Japan's Kantō region along its east coast.
Preparations
Japan's Prime Minister Shinzō Abe left a Japan-African development conference in Nairobi, Kenya early due to the threat of flight cancellations caused by the typhoon. Prior to Lionrock making landfall, a total of 100 flights were cancelled at airports in Tohoku and Hokkaido. Efforts were made to protect the Fukushima Daiichi Nuclear Power Plant from further damage, as it had been severely incapacitated following the 2011 Tōhoku earthquake and tsunami. The amount of water being pumped at the facility was increased in order to minimize the risk of floods, and crane operations were suspended due to the threat of strong winds.In eastern Russia, a storm warning was announced on 28 August by EMERCOM. All emergency services and troops were on high alert. Local authorities were informed on emergency procedures.
North Korea's Early Warning and Evacuation system was activated ahead of the storm, causing 44,000 people in flood-prone areas to be evacuated in North Hamgyong Province.
Impact
Japan
Upon making landfall on August 30, Lionrock brought very heavy rainfall, including at Mount Nukabira, in Hokkaidō Prefecture, and in Orito in Iwate Prefecture. In addition, a maximum wind gust of was recorded in Ishinomaki, and a wind gust was measured in Onagawa. Lionrock killed a total of 22 people across Japan, including 19 people in the town of Iwaizumi in Iwate Prefecture. 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. Damage due to flooding were standing at JP¥282 billion.Russia
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. The storm also caused power disruptions. 12,000 rescue workers were also deployed in the area.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. 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. In addition, two EMERCOM officers died when their KAMAZ truck fell into the Pavlovka River. Lionrock was the worst typhoon to hit the Primorsky Krai region in 40 years, with total damage exceeds ₽7 billion.
China
A total of of agricultural land were impacted in China, including 53,500 hectares of crops which were destroyed due to floods. Damages in China are estimated to be CN¥7.21 billion ; most of which was inflicted on the agricultural sector.North Korea
Lionrock interacted with a low pressure area over China to drop heavy rainfall in North Korea, mostly in North Hamgyong Province, considered by the state media Korean Central News Agency to be the "heaviest downpour since 1945". Over a two-day period, Kyonghung County recorded of rainfall. This caused flooding along the Tumen River and its tributaries, inundating about of farmlands just weeks ahead of the harvest, of which were wrecked.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. The affected area had poor infrastructure and deforestation on hills, exasperating the floods' impacts. Entire villages were washed away, carrying away families' entire possessions. Three people trapped in floodwaters were rescued by two Chinese rescue boats. Over 35,500 houses were damaged, of which around 25,000 were destroyed, forcing 107,000 people from their homes; many of these people sheltered on higher grounds or in public buildings. Floods from Lionrock damaged another 8,700 non-residential buildings, including schools and public buildings. In Ryanggang Province, the heavy rains caused a five-story building to collapse, killing 34 people. 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. The floods also washed away six bridges and of roads, with of road bed damaged. The floods related to Lionrock killed at least 525 people in the country.
