The 2021 Fukushima-ken Oki (Fukushima Prefecture Offshore) earthquake (Japanese: 福島県沖地震, Hepburn: Fukushima-ken'Oki Jishin) was a very intense and deadly seismic event that struck offshore east of Tōhoku, Japan. The Mw  7.1 or MJMA  7.3 earthquake occurred on a Saturday night at 23:07 JST (14:07 UTC) on 13 February at a relatively shallow focal depth of 51.9 kilometers (32.2 mi).[12] It had a maximum JMA intensity of Shindo 6+ to Shindo 7 while on the Mercalli intensity scale, it earned a rating of VIII (Severe).[13] The earthquake was followed by multiple aftershocks within less than an hour, three of which registering magnitude 5.3.[14] The earthquake itself has been considered an aftershock of the 2011 Tōhoku earthquake which had occurred almost ten years prior.[15]

The earthquake left one person dead, and at least 186 injured.[7][6] It also inflicted significant structural damage across the Tōhoku and Kanto regions.[16][11][17][18] This earthquake resulted in both insurance claims and losses exceeding ¥138 billion (US$1.3 billion).[1] Small tsunami waves were also observed without any damage. Because of its proximity to the Fukushima Daiichi Nuclear Power Plant, the event provoked concerns of radiation leaks but were dismissed soon after. Although there were no changes to the level of radiation, cooling water used in two of the reactor units were discovered leaking, indicating damage.

Preface[]

Further information: 2011 Tōhoku earthquake and tsunami

The 11 March 2011 Tōhoku earthquake struck off the coast of eastern Japan, with an epicenter north of Sendai, and a hypocenter depth of 29 km.[19] It was the largest instrumentally recorded earthquake in the country, and the fourth largest ever recorded worldwide.[20] This earthquake generated massive tsunamis measuring up to 41 meters in height, the highest in Japan.[21] It swept through the Kantō Plain, destroying towns and cities. The tsunami also caused a series of catastrophic nuclear meltdowns at the Fukushima Daiichi Nuclear Power Plant shortly after. In all, an estimated 20,000 people lost their lives due to both the earthquake and tsunami. The disaster resulted in economic losses of US $360 billion, making it the costliest natural disaster in history.[22]

Tectonic setting[]

Seafloor expression of the East Japan subduction zone marked by the Japan Trench where earthquake activity occurs frequently.

The Pacific Plate, made of oceanic lithosphere, subducts beneath the Okhotsk Sea Plate along a convergent boundary located off the east coast of the northern half of Japan.[23] It runs from the Boso Triple Junction and ends near Hokkaido, where it joins the Kuril Trench. At the location of this earthquake, the Pacific plate moves approximately westward relative to the North American plate at a velocity of 70 mm/yr, subducting beneath Japan at the Japan Trench and dipping to the west beneath Japan. This subduction zone is capable of producing megathrust earthquakes with magnitudes greater than 8.5, as seen in the historical records. It was on the subduction interface where the 2011 earthquake nucleated. That event involved a 220 by 400 km section of the subduction zone that had ruptured.[24]

The most recent similar-sized event of this scale was the 6.9 Mw  or 7.4 MJMA  2016 Fukushima earthquake, which occurred just southwest of where the February 2021 earthquake took place at.[25] That earthquake was a result of normal faulting within the overriding Okhotsk Sea Plate at a depth of 9 km.[25] The Japan Meteorological Agency observed a maximum intensity of Shindo 5 Lower,[26] or VII (Very strong) according to the US Geological Survey. A moderate tsunami of 1.4 meters struck the Sendai area shortly after, the largest since the 2011 disaster.[27] Minimal damage and few casualties were caused.

Earthquake[]

The earthquake occurred as the result of reverse faulting within the subducting Pacific Plate, and not on the subduction interface itself. Therefore, it could be considered an intraplate earthquake.[28] Moment tensor solutions indicate that slip occurred either on a moderately dipping fault striking to the south, or a moderately dipping fault striking to the north-northeast, consistent with the east-west oriented compression expected in this region.[29][12] Meanwhile, the Earthquake Research Committee from the Japanese government said the earthquake ruptured along a 45 km-long, north-south striking fault that dips towards the east.[30] According to the US Geological Survey, the earthquake struck at a depth of 51.9 km, while the Japanese Meteorological Agency placed its depth at 55 km, a revision from the initial 60 km.[28]

According to the Japan Meteorological Agency, the earthquake had a maximum intensity of Shindo 6 Upper, which would correspond to intensity VIII (Severe) to X (Extreme) on the Mercalli intensity scale.[11] These intensities were recorded in Fukushima and Miyagi prefectures. However, the Earth Science and Disaster Prevention Research Institute found that the earthquake may have also caused shaking as high as Shindo 7 in Yamamoto, Miyagi.[4] At the same location, the maximum peak acceleration caused by the earthquake was recorded at 1,432 gals, far exceeding the 980 gals and 1,362 gals recorded in Mashiki, Kumamoto during the 2016 Kumamoto earthquakes which were assigned Shindo 7.[32]

In addition to violent ground motions, extreme long period ground motion was also recorded. The intensity of the reached a maximum of Class IV in Fukushima's Nakadori Region, the first time that level of intensity was observed after the 2018 Hokkaido Eastern Iburi earthquake.[34] Class IV intensity has been observed only four times since the scale was first used in 2013 and the first time it was measured since full time operation of the scale began in 2019.

Class IV Long Period Ground Motion (LPGM) results in people finding it impossible to move without crawling, fixtures on casters will move wildly and may fall over, unsecured furniture will be more likely to fall over and there will be many cracks in partition walls. Class III LPGM results in people finding it hard to stand, fixtures on casters will move about and unsecured furniture may fall over and partition walls will crack. Class II LPGM will result in people finding it difficult to walk without holding onto something stable, fixtures on casters will move slightly and objects on shelves may fall. Class I LPGM will result in people feeling the slight shaking and may feel startled, and hanging items like lamps and window blinds will move significantly.[35]

Nine days after the 10th anniversary of the March 2011 tragedy, a strong 7.0 Mw  or 6.9 MJMA  earthquake struck 80 km north of the epicenter of the February 2021 event.[71] The earthquake struck at 18:09 local time, 54 km beneath the coast of Miyagi Prefecture. A tsunami warning for waves up to 1 meter was broadcast but was rescinded shortly after. So far, a few injuries have been reported and there is no serious structural damage to buildings. The same prefecture was also significantly affected by the Fukushima earthquake.[72] It is unknown if the 20 March event is related to the earthquake a month earlier but both were a result of thrust faulting on or near the subduction zone and in the zone of rupture of the 2011 quake.[73]

Earthquake and tsunami warnings[]

The Japan Meteorological Agency issued an Earthquake Early Warning at 23:08:10.2 or 10 seconds after the earthquake was detected, in all of Miyagi and Fukushima prefecture, the Murayama and Oki districts in Yamagata prefecture, and the northern and southern inland areas of Iwate prefecture. Announced were made in the northern Ibaraki prefecture. Warnings were issued shortly after at 23:08:33.8 to Aomori prefecture 's Nanbu, Akita prefecture 's southern part, Iwate prefecture's northern and southern coast, Yamagata prefecture's Mogami and Shonai regions, southern Ibaraki prefecture, Tochigi Prefecture and Gunma Prefecture. The follow-up report of the emergency earthquake bulletin was announced in Saitama prefecture, northern Chiba prefecture, and the Kaetsu and Chuetsu regions of Niigata prefecture.[33]

Many television channels were interrupted by early warnings of the earthquake broadcast by the JMA.[74] Scheduled programs in television stations across the country was replaced by live coverage of the earthquake shortly after it struck. Regular programmes resumed after several hours or days of emergency coverage of the earthquake. In response, viewers in some areas were free from viewing fees for stations including Fuji TV and NHK, which exempted fees for viewers in the affected areas for two months.[75]

Tsunami[]

Because of the earthquake's focal depth and size, no formal warning was issued to the Japanese coast.[76] Seven minutes after the earthquake, the Japan Meteorological Agency projected "slight sea level fluctuation" to occur along the Tōhoku and Kanto coasts.[77] A non-destructive 20 cm tsunami was observed at a port in Ishinomaki, Miyagi Prefecture at 01:44 local time on 14 February.[78] Smaller waves of 10 cm (3.9 Inches) (100 mm) was observed in ports in Sendai and Soma at 01:21 and 02:48 local time respectively.[79]

Casualties[]

The earthquake resulted in at least 186 people injured across nine prefectures,[7][80][13] with most coming from Fukushima Prefecture, as said by the Fire and Disaster Management Agency.[8] There, some 100 people were reported hurt.[11] In Miyagi, the earthquake injured 63 residents, with 30 coming from Sendai. There were 17 people injured in Yamagata, Ibaraki, Gunma, Tochigi, Saitama, Chiba, and Kanagawa prefectures.[78] Most of the injuries reported were minor, caused by glass cuts, however, 16 victims were seriously injured.[10]

One person suffered serious injuries in Ōshū, Iwate, and was the only casualty in Iwate Prefecture. In Miyagi Prefecture, one victim was reported the cities Ishinomaki, Kurihara and Higashimatsushima, all with major wounds.[7] Another fifty-eight individuals in Miyagi had small injuries. From Fukushima Prefecture, four residents, two from Fukushima City and one each from Koriyama and Koori were inflicted with major lacerations and bruises. At least 95 others in the prefecture also had less serious trauma. Other prefectures including Ibaraki, Tochigi, Gunma, Saitama, Chiba and Kanagawa also reported one or more profound or insignificant injuries.[7]

On 23 February, ten days after the earthquake, the body of a man in his 50s was discovered by a family member, buried under furniture in his house in Fukushima City. Local government officials said the man had suffocated as he was pinned under falling furniture, toppled by the earthquake.[81] They estimate his time of death at just after 23:07 local time on 13 February.[82] He is the only known fatality from the earthquake and the first earthquake related fatality in Japan since 2018.[6]

Impact[]

According to the General Insurance Association of Japan as of 12 May 2021, at least 221,994 insurance claims had been filed for in damages caused by the earthquake. At least 112,047 claims were from Miyagi Prefecture and 81,538 from Fukushima Prefecture. Claims were also filed in other prefectures including Iwate, Yamagata, Ibakari, Tochigi, and Saitama. The number of claims from these prefectures were collectively counted at 28,409.[1] Of the nearly 222,000 filed claims, some 165,866 of them were settled and 133,359 claims were paid were done. The total number of claim payments made is estimated at ¥138,275,181 or about USD 1,262,528. In April, before paid claims totaled the USD 1 billion mark, the Catastrophe Risk Evaluation and Standardizing Target Accumulations organization said that the earthquake could result in a billion dollars worth of losses and insurance claims for the insurance and reinsurance industry.[83][84]

According to a government spokesman, more than 950,000 homes did not have access to power, and many power plants throughout the country went offline.[15] Fukushima Prefecture was the hardest hit with most of the casualties and damage reported. Miyagi Prefecture also reported substantial damage and had the second-highest casualty numbers by prefecture, behind Fukushima. Thirty-two houses, two in Miyagi and 30 in Fukushima prefectures were totally destroyed by the earthquake. Another 259 suffered serious structural damage in Fukushima, Miyagi, and Saitama prefectures. In Yamagata Prefecture, 15 residential buildings sustained some minor damage. Other locations including Iwate, Chiba, Kanagawa, Niigata, and Tokyo had between one and four buildings damaged, although they were minor.[7] In total, 9,137 buildings throughout the area suffered damage.[7]

The most severely affected city was Sōma, located some 40 kilometers (25 mi) north of the Fukushima Daiichi Nuclear Power Plant.[85] In the same location, a car ran into the path of a rockfall, resulting in the driver sustaining a minor neck injury. A 100-meter-long (330 ft) section of the fishing port in the city experienced vertical displacement of up to 10 centimeters (3.9 in). The port also suffered liquefaction when sand erupted from fissures in the asphalt.[86] There were also reports of conflagrations from local authorities.[87]

In Sendai, the walkway of an apartment block on the second floor collapsed. No one was injured from the collapse, however one resident was trapped for a while and later rescued through a window.[88]

At least 311 schools in Fukushima and Miyagi prefectures sustained damage such as cracked walls and floors, broken windows as well as burst water pipes. This prompted the closure of 71 schools in both prefectures.[89]

Small fires broke out in Sendai and Shiogama in Miyagi as a result of the earthquake. One involved a dress shop while the other was in an apartment. They were both extenguised by the fire department with no casualties known.[7]

Footage and images circulating online suggest that minor damage including broken glass and collapsing facades were caused by the shaking. Home videos taken during the earthquake also show cabinets and shelves toppling over. In Tokyo, the earthquake caused buildings to sway about.[90]

Historical sites[]

The Zuihōden Temple in Aoba-ku, a ward in Sendai, was one of the historical sites damaged by the earthquake. About 100 stone lanterns and tombstones collapsed as a result of the earthquake. The main shrine structure remained intact without any major damage. A thorough investigation to determine the condition of the structure and repair cost would be carried out, according to a spokesman.[91] The same temple suffered substantial damage during the 2011 earthquake when its stone wall was brought down, and 200 lanterns and tombstones were destroyed.[91]

The earthquake also caused structural damage to the Shiroishi Castle in Shiroishi, Miyagi. Cracks were reported in the exterior walls in the third floor of the castle's tower. In response to, all admissions to the castle were cancelled.[92] Aftershocks, wind and rain in the days following the earthquake caused damage at the castle's tower to spread further. Inspectors said some of the castle tower walls have to be replaced entirely due to the severity of damage. The estimated cost of damage in Shiroishi City is ¥500 million while the at castle, ¥200 million.[93]

At the Inari Shrine area in Fukushima, a piece of a stone lantern fell from a height of five meters onto a parked car, greatly deforming the car. There were no occupants in the car at the time of the incident.[94] The main shrine itself was not damaged and therefore reservations for normal shrine affairs carried on.[95]

Fukushima Daiichi Nuclear Power Plant[]

According to the Tokyo Electric Power Company (TEPCO), no abnormalities or changes in radiation levels were detected immediately after the earthquake. Approximately 20 minutes after the shock, a nuclear alert order was issued and both the water treatment and transfer facilities were shut down. Inspections began some 50 minutes after the quake but no anomalies in the reactor units were found. Subsequent inspections the next day also showed no unusual changes to radiation level and the nuclear alert order was rescinded at 2:00 pm on 14 February.[96]

About a week after the earthquake, TEPCO stated that water levels in reactor Units 1 and 3 which were crippled by the 2011 nuclear meltdown had dropped by several tens of centimeters, and has continued to fall each day.[97][98] Water used to cool the nuclear fuel had been leaking from the damaged units since the earthquake occurred. In reactor Unit 1, water level fell by some 40 to 70 centimeters beginning on Monday while reactor Unit 3 began leaking on Sunday, lowering the water level by 30 centimeters. TEPCO further reassured that were no change in radiation levels following the earthquake.[97]

A TEPCO spokesperson said that leaking water is contained within the reactor buildings and is not exposed to the outside environment.[99] This additional damage may cause further implications in the decommissioning process of the nuclear power plant which is expected within several decades. Additional water is needed to cool the melted nuclear fuel to compensate for these new leaks.[99]

Transportation[]

Schedule of the Tohoku-Hokkaido Shinkansen which was suspended due to the earthquake.

The East Japan Railway Company suspended their Tōhoku–Hokkaidō, Akita, and Yamagata Shinkansen services after an inspection revealed damage to various pieces of equipment. In Kōriyama City, the earthquake snapped utility poles off their base along the railway line. The railway company had mentioned that operations between Nasushiobara and Morioka stations would be suspended for around 10 days to allow for repair works.[100] In response to the disaster, service was reduced to one train per hour between Tokyo and Nasushiobara stations.[101]

The Jōetsu and Hokuriku Shinkansen also experienced a brief suspension of service but resumed regular operation shortly after.[102]

Services on the two Mini-shinkansen lines (Akita and Yamagata Shinkansen) were scheduled to be restored by 15 February between their northern termini and their respective endpoints along the Tōhoku Shinkansen.[needs update][103]

Commuter rail lines were also affected, with the Tōhoku Main Line and Jōban Line experiencing delays of various extents. In addition, all services on the Abukuma Express Line were suspended indefinitely.[103]

Due to the suspension of the Shinkansen, Japan Airlines and All Nippon Airways (ANA) set up extra flights to the airports of several cities cut off from the Shinkansen network including: Akita Airport, Aomori Airport, Fukushima Airport, Hanamaki Airport, Sendai Airport, Shonai Airport, and Yamagata Airport.[104] These additional flights were scheduled through 15 February. Supplemental bus services were began operations on behalf of JR Bus Tōhoku.[103] JR Bus Tōhoku added more than 20 service routes connecting Fukushima and Sendai stations to the nation's capital, Tokyo.[89]

On the Jōban Expressway, landslides buried parts of the roadway, and embankments along it collapsed; however, no vehicles were trapped inside the debris.[87] A 10-meter-long (33 ft) section of the expressway at another location was uplifted.[105] In response, the East Nippon Expressway Company deployed heavy equipment to remove boulders and clear up debris along the expressway.[106] By 17 February, the blockages along the expressway were cleared allowing traffic to resume along the route. Fences were also erected along the stricken sections of the expressway to prevent further rockslides.[107]

Another landslide in Nihonmatsu partially buried the Ebisu Circuit, a race track located along the slopes of a mountain. The landslide took with it cars and a double-story building, eventually burying them. The race track also cracked as a result of the ground slumping.[108]

University exams[]

As a result of the temporary suspension of the Tōhoku-Hokkaido Shinkansen, some students from six prefectures in the Tohoku region were unable to take entrance exams administered by some private universities at the designated venues. In response, some universities postponed the test dates or conducted a retest altogether.[109]

At Tōhoku University, a test venue for an exam administered by the Faculty of Law was changed from the Kawauchi Campus to the Katahira Campus when issues regarding the seismic integrity of the structure arose following the earthquake.[110]

The entrance examination commencement time for students at the Faculty of Economics at Chuo University was set an hour later from the intended time of 10:30 on 14 February at their venue in Sendai.[111] A similar situation occurred at Hosei University in four of their faculties when exams were delayed for one hour and a half the same day. These universities had expected that some students may not arrive at the venue on time because of the earthquake.[112]

Keio University said that students affected by the interruption of service along the Tōhoku Shinkansen would be able to sit for exams conducted by the Faculty of Law and Faculty of Letters on 9 March. Exams were originally held on 15 and 16 February.[111]

Both Waseda University and Hosei University made statements that a pass/fail grading would be made based on performance in a previous test to students who are unable to take the exams.[111]
