Assessment of the Impact of August 2021 Rainfall and Flooding in the DPRK

In August 2021, the Democratic People's Republic of Korea (DPRK) experienced heavy rainfall and severe flooding. ONN has analysed available open-source information and identified locations of possible damage and assessed the scope of such damage. This paper provides a summary of ONN's findings.

Key Findings

From 1 to 3 August 2021, multiple cities and counties in North Hamgyong Province and South Hamgyong Province in the DPRK were affected by heavy rainfall which recorded precipitation levels that far exceeded historical averages. Reportedly, the heavy rainfall and flooding affected houses, roads, bridges and agricultural fields in the region. The scale of the reported damage this year appears to be as extensive as the damage highlighted in DPRK media in August 2020.

For most of the subsequent days in August, heavy rainfall occurred in various regions throughout the country, which appears to have caused additional damage to these two provinces as well as damage to other provinces not reported in DPRK media.

In order to assess the impact of the heavy rainfall and flooding on the DPRK in August 2021, ONN gathered and analysed information from DPRK media and satellite imagery, as well as data from monitoring stations in or near the DPRK.

ONN's findings are summarized below:

  • The extensive damage to building/housing areas, roads, bridges and riversides in North Hamgyong Province and South Hamgyong Province, as reported in DPRK media, can be confirmed through satellite imagery. Although they were not mentioned in DPRK media, other provinces were also adversely impacted.

  • According to DPRK media reports, several square kilometres of agricultural fields in South Hamgyong Province were flooded, while 17 km of roads, 8.1 km of embankment and multiple bridges were damaged. Based on available satellite imagery, ONN has confirmed that, at a minimum, approximately 3.7 km2 of agricultural fields and approximately 6.8 km-long roads and embankments were affected in or near Sinhung County and Yonggwang County in South Hamgyong Province, the most heavily damaged areas in the DPRK due to the heavy rainfall and flooding in early August. While the full extent of the damage is not yet precisely known, the scale of the affected areas suggests that the damage may have a significant impact on crops in the coming weeks.

  • DPRK media has also reported that the heavy rainfall and flooding appear to have created damage in North Hamgyong Province. The affected areas include the Komusan area in North Hamgyong Province where the Komusan Cement Factory is located. According to a DPRK media report, this factory is equipped with "a high-quality refractory workshop" and has served as one of the key producers of cement products in North Hamgyong Province. Satellite imagery shows that the railways used by this factory were flooded and possibly damaged. Prolonged damage to these railways could constrain the local capacity to produce and supply cement products to reconstruction sites in affected areas.

  • Water levels have risen significantly at dams and water reservoirs, recovering from the reduced levels caused by the drought in July. Although there are signs of possible overflow of water at some of the reservoirs, there are no visible signs of damage to these dams or reservoirs.

  • No damage could be observed at most facilities known to be related to the DPRK's nuclear or ballistic missile programmes, with the exception of the Tonghae Satellite Launching Ground where some of the buildings were flooded. However, it is unclear whether these buildings were damaged.

  • The precipitation levels in August reported by monitoring stations in and near the DPRK indicate several unusual spikes that are many times higher than historical averages, particularly on and around 10 and 21 August. As of 31 August 2021, the monsoon season had not yet concluded in the DPRK. A prolonged period of heavy rainfall and flooding could further weaken the soil, which could cause further damage to roads, railways, riversides and agricultural areas. To prevent additional damage, further measures would be needed for the DPRK to ensure the integrity of these structures and locations.

  • Some regions in the DPRK experienced only low levels of precipitation in August, including Pyonggang County in Kangwon Province, where a drought has been continuing since midJuly.

In summary, the DPRK has suffered from extreme weather conditions - both heavy rainfall and drought - some of which continue to prevail. The extreme weather conditions are expected to impose significant economic and social costs on the DPRK.

Introduction

On 5 August 2021, Korean Central Television (KCTV) reported that multiple cities and counties in North Hamgyong Province and South Hamgyong Province (Figure 1) experienced heavy rainfall with precipitation levels significantly greater than historical averages. Damage reportedly occurred to houses, roads, bridges and agricultural fields in the region. [1]

Heavy rainfall continued to occur throughout the rest of August in various regions in the country, which appears to have caused additional damage to these two provinces as well as damage to other provinces not explicitly reported in DPRK media.

Precipitation in August 2021

From mid to late July 2021, the DPRK experienced widespread drought. For most regions in the country, however, this was followed by heavy rainfall in August. [2] Although North Hamgyong Province and South Hamgyong Province were not the only regions which experienced heavy rainfall in August, they appear to have been the most significantly affected, which could explain why DPRK media reports focussed on those two provinces.

The precipitation levels for August reported by 19 DPRK monitoring stations and four Chinese monitoring stations near the border with the DPRK [3] recorded unusual spikes far higher than historical averages, [4] in particular on or around three specific periods (1-3 August, 10-13 August and 21 August), as can be seen in Figures 2.a through 2.d below. Most of these spikes also exceeded those recorded during the same time period in 2020.

On the other hand, some regions experienced low precipitation, including Pyonggang County in Kangwon Province, which has been suffering from drought since mid-July. Overall, many regions of the DPRK appear to have experienced extreme weather conditions, whether continuing drought or heavy rainfall.

Damage Reported by DPRK Media

DPRK Media Reporting in August 2021

According to KCTV, Puryong County in North Hamgyong Province experienced the greatest volume of rainfall in the DPRK and recorded the highest precipitation level of 583 mm between 1 and 3 August 2021. Sinhung County in South Hamgyong Province recorded the second highest precipitation level of 308 mm for the same period (Figure 3). [5]

Other areas of these two provinces were also affected, including Hamhung, Hochon County, Pujon County, Pukchong County and Rakwon County and Tanchon in South Hamgyong Province, and Kilju County in North Hamgyong Province, which recorded precipitation levels between 158 and 202 mm for the same period (Figure 3).

KCTV aired video footage showing extensive damage to South Hamgyong Province caused by heavy rainfall and severe flooding, in particular, to houses, roads, bridges and agricultural fields (Figure 4). Subsequent reporting by Rodong Sinmun and Korea Central News Agency (KCNA) identified damage to other areas in the South and North Hamgyong Provinces, including Hongwon County and Yonggwang County in South Hamgyong Province and Puryong County in North Hamgyong Province. [6]

Comparison of Reported Damage in August 2020 and August 2021

Figure 5 below compares the damage due to heavy rainfall and flooding in South Hamgyong Province in early August 2021, as reported by DPRK media, with the damage reported in August 2020 for Unpha County in North Hwanghae Province, which was likely the most significantly affected area in the DPRK at that time.

Figure 5. Comparison of reported damage from heavy rainfall and flooding in August 2020 and August 2021. Source: KCNA and KCTV [8]

While the scale of the reported damage is difficult to compare due to a lack of available common data points, the damage reported in August 2021 appears to be of a scale similar to that reported in August 2020.

According to KCTV, in early August 2021, nearly 17 km of roads and multiple bridges were damaged. In addition, about 8.1 km of embankments were damaged, which resulted in the flooding over several square kilometres of agricultural fields. In August 2020, DPRK media did not report the number of roads, bridges or embankments affected by flooding, but did report that 6 km2 of rice fields had been inundated.

In August 2020, DPRK media reported that approximately 730 single-floored houses were inundated and 179 blocks of dwelling houses were destroyed, as compared with the 1170 homes reported to have been destroyed or flooded in early August 2021. DPRK media reported that 5,000 people were forced to evacuate the affected areas in August 2021. No comparable data was reported for August 2020.

ONN has confirmed through satellite imagery analysis that, at a minimum, approximately 3.7 km2 of agricultural fields and approximately 6.8 km of roads and embankments along rivers had been affected in and near Sinhung County and Yonggwang County, the most heavily damaged area in the DPRK in early August.

The heavy rainfall and flooding in 2020 had already caused considerable damage to the harvest and food supply in 2021. This was acknowledged by Kim Jong Un in his speech on 15 June 2021 during the 3rd Plenary Meeting of the 8th Central Committee of the Workers' Party of Korea, in which he stated that "the people's food situation is now getting tense as the agricultural sector failed to fulfill its grain production plan due to the damage by typhoon last year". [9] While the full extent of the damage as a result of the August 2021 rainfall and flooding is not yet precisely known, the scale of the areas affected suggests that the damage will likely negatively impact agricultural crops in the coming weeks. Extensive damage to the agricultural fields in 2021 could further destabilize the DPRK's efforts to ensure a stable supply of food.

Assessment of Damage

ONN has analysed satellite imagery from August 2021 of the estuaries throughout the DPRK in search of signatures of heavy rainfall and flooding, [10] and has identified the following areas as having been the most significantly affected by the heavy rainfall and flooding in August in the DPRK:

1. Hamhung in South Hamgyong Province;

2. Areas between Yonggwang County and Sinhung County in South Hamgyong Province;

3. Sinhung County in South Hamgyong Province; and

4. Komusan in Puryong County, North Hamgyong Province.

ONN also identified possible damage in the following areas in North Hamgyong Province, albeit with a medium confidence level due to a limitation on the availability of high-resolution satellite imagery: Hwadae County; an area at the administrative border between Hwadae County and Kimchaek; and Kimchaek.

In addition to having damaged infrastructure, such as roads, embankments, houses, buildings and waterways, the heavy rainfall and flooding appear to have damaged some railways, including those used for industrial purposes. Prolonged damage to these railways could constrain the local capacity to produce and supply products needed for reconstruction efforts in the affected areas.

Water levels have risen significantly at dams and water reservoirs, recovering from the reduced levels caused by the drought in July. Although there are signs of possible overflow of water at some of the reservoirs, there are no visible signs of damage to these dams or reservoirs.

No damage could be observed at most facilities known to be related to nuclear or ballistic missile programmes except the Tonghae Satellite Launching Ground, where some of the newly constructed houses or facilities were flooded. However, it is unclear whether these structures were damaged.

Areas with Damage

Hamhung, South Hamgyong Province

Hamhung

DPRK media frequently referred to Hamhung as one of the areas that was significantly affected by heavy rainfall and flooding and where reconstruction activities were being undertaken. High precipitation levels in Hamhung were recorded on 1, 10 and 21 August (Figure 6).

Precipitation at Hamhung in South Hamgyong Province

Satellite imagery confirms extensive damage in and near Hamhung, especially in early August, including damage to bridges and roads, buildings and agricultural fields, and water overflow from a reservoir. Extensive damage can be observed in particular in areas in or near the Hoesang District of Hamhung.

On 9 August, Rodong Sinmun reported on "road restoration work" between Ssangbongri and Ryeongbong-gul in the Hoesang District. [11] Damage to multiple areas in that district can be confirmed.

Due to the heavy rainfall, a large amount of water was accumulated in a water reservoir in the district. When the water was released from the reservoir, a wide area of agricultural fields downstream was flooded. Satellite imagery shows that approximately 3.5 km of the embankment was breached and agricultural areas along the embankment were flooded.

In addition, flooding caused by heavy rainfall in several mountain ridges damaged residential areas and roads along the rivers in the valleys (Figures 7 to 9).

A large volume of water was released from a dam

Areas between Yonggwang County and Sinhung County, South Hamgyong Province

Sinhung-Yonggwang

On 9 August, Rodong Sinmun reported on “road restoration work” between Yonggwang County and Sinhung County in the South Hamgyong Province (Figure 10). [12]

Sinhung County-Yonggwang County-Hamhung

Consistent with the reporting, satellite imagery from 3 August confirms extensive damage from flooding along the Songchon River and the roads between Yonggwang County and Sinhung County, a distance of approximately 21 km (Figure 11). Available satellite imagery shows that, at a minimum, over 2.5 km2 of agricultural fields were flooded along this river. As of 22 August, several embankments had not yet been repaired and water had not yet receded from several flooded agricultural fields.

In addition, several waterways along the Songchon River were filled with sediment or destroyed during the flooding (Figure 12). These waterways may have been used as irrigation canals or for the purpose of supplying water to fisheries or agricultural areas. The damage to these waterways could negatively impact agricultural and fishery operations in the surrounding area.

Sinhung County, South Hamgyong Province

Sinhung

Satellite imagery confirms extensive damage in and near Sinhung County, including extensive flooding in the centre of the county and two damaged bridges (Figure 13). [13]

Puryong County, North Hamgyong Province

Komusan

Komusan in North Hamgyong Province was also affected by the heavy rainfall and flooding (Figure 18). Noteworthy, in particular, is the damage to the Komusan Cement Factory. According to a report in DPRK media, the factory is equipped with "a high-quality refractory workshop" and has served as one of the key producers of cement products in North Hamgyong Province (Figure 18). [15] Satellite imagery from 3-4 August shows that the railways used by this factory and the Komusan train station close to the factory were flooded. Satellite imagery from 19 August shows that the railways appeared to have been still covered by sediment, indicating that the damage had not yet been repaired. Prolonged damage to these railways could constrain local capacity to produce and supply cement products to reconstruction sites in the affected areas.

Other Areas with Signs of Possible Damage

ONN has found other areas in the DPRK with signs of possible flooding in North Hamgyong Province, including Hwadae County, an area at the administrative border between Hwadae County and Kimchaek, as well as in Kimchaek. While clear signs of damage were hard to confirm through available satellite imagery, these areas could be further affected in the coming weeks by heavy rainfall and flooding.

Hwadae County, North Hamgyong Province

Hwadae County

Hwadae County is located approximately 200 km northeast of Hamhung. This county was also affected by heavy rainfall and flooding at least twice in August. Satellite imagery shows that a bridge over a main road along the eastern coast of the DPRK was flooded on 3 and 22 August (Figure 19). While no clear damage to the bridge could be observed from the satellite imagery of 30 August, repeated flooding could undermine the strength of the bridge which serves as one of the key nodes in land transportation along the DPRK's eastern coast.

 Repeated flooding of the bridge in Hwadae County

Hwadae County and Kimchaek, North Hamgyong Province

Hwadae County-Kimchaek

A key bridge over the Namdaechon River at the administrative border between Hwadae County and Kimchaek has also been adversely impacted by the heavy rain and flooding. The bridge was already damaged sometime before 3 June 2021 and was further damaged by flooding in August. As of 30 August, the bridge had still not been repaired (Figure 21).

Kimchaek, North Hamgyong Province

Kimchaek

According to a KCTV report, the city of Kimchaek also experienced heavy rainfall in August. Satellite imagery from August 2021 shows that one of the key bridges in Kimchaek may have been damaged and repaired sometime between 19 and 28 August. Available satellite imagery from 22 August shows a possible sign of construction work at the bridge (Figure 23).

Dams and Water Reservoirs

As noted above, water levels have risen significantly at dams and water reservoirs (Figure 24). The dams and reservoirs, which experienced a drought in July, were refilled with water, and the water levels appear to have recovered (Figure 25). Although there are signs of possible overflow of water at some of the reservoirs, there are no visible signs of damage to these dams or reservoirs (Figure 26).

Nuclear and Ballistic MissileRelated Facilities

No damage was observed at most facilities known to be related to the DPRK's nuclear or ballistic missile programmes. The only exception is the Tonghae Satellite Launching Ground, where some of the suspected launch control/administrative buildings and surrounding smaller buildings were flooded, but it is unclear whether these structures were damaged as a result of the flooding (Figure 27). [17]

Conclusion

Heavy rainfall and flooding have caused considerable damage to many regions in the DPRK. The scale of the reported damage this year appears to be close to the damage highlighted by DPRK media in August 2020. The rainy season may continue throughout September as it did in 2020. A prolonged period of heavy rainfall and flooding could further weaken the soil, which could cause further damage to roads, railways, riversides and agricultural areas. To prevent additional damage, further measures would be needed for the DPRK to ensure the integrity of these structures and areas.

On the other hand, there are some regions which have experienced sustained low levels of precipitation, including Pyonggang County in Kangwon Province, where drought has been continuing since mid-July.

In summary, the DPRK has suffered from extreme weather conditions throughout August 2021 and continues to do so. While some regions suffered from drought, others suffered from heavy rainfall and flooding. The extreme weather conditions are expected to impose significant economic and social costs on the DPRK.

The DPRK leadership will need to invest a considerable amount of time and energy in reconstruction and damage prevention and mitigation until the rainy season concludes in the fall.
