Japan lifted a tsunami advisory on Wednesday and check-in resumed at Okinawa‘s main airport where flights had been suspended following a powerful earthquake in Taiwan.
The Japan Meteorological Agency (JMA), which had initially warned of a risk of tsunami waves up to three metres (10 feet) high in the southern island region of Okinawa, said much smaller waves had been recorded in several locations.
On Yonaguni Island, close to Taiwan, waves of up to 30 centimetres (12 inches) arrived at 9:18 am Japan time (0018 GMT), 18 minutes after the earthquake hit.
Waves of the same height were also recorded on Miyako Island at 10:50 am, while a 20 cm wave was seen on Ishigaki Island at 10:42 am, the JMA said.
Operations at Naha Airport, the main aviation hub for Okinawa, had been suspended as a precautionary measure with incoming flights diverted elsewhere, according to a transport ministry official stationed at the airport.
But TV footage showed people being allowed to check in again later in the day.
The commencement of flight operations from the new integrated terminal building started from August 21, 2023. With a total built-up area of 40,837 sqm, the new terminal building is capable of handling 1,200 passengers during the busiest operational hour. The passenger volume from April to February this year is more than 13 lakh which is more than 12.5 per cent in comparison to the passenger volume of the previous year.
The main shock that hit eastern Taiwan on Wednesday morning had a magnitude of 7.4, according to the United States Geological Survey (USGS).The JMA had given a preliminary estimate of magnitude 7.5 for the earthquake, but later upgraded that to magnitude 7.7.
