Japan issued a tsunami advisory Tuesday morning following a 6.9-magnitude earthquake in northern Japan, the meteorological agency said.
The agency said a tsunami of up to one metre (3.3 feet) was forecast to hit the coast of Iwate at around 8:30 am (2330 GMT Monday).
Television footage has so far shown no major change in sea levels around the seashore in Miyako, eastern Iwate.
The quake struck at 8:06 am in the Pacific some 210 kilometres (130 miles) east of Miyako at a depth of 10 kilometres, the agency said.
There were no immediate reports of injuries or casualties following the quake, local media said.
Large areas of the coastline covered by the advisory were damaged by the 2011 quake and tsunami that killed more than 18,000 people and triggered a nuclear accident in Fukushima.
The city of Ofunato in Iwate issued an evacuation advisory to more than 1,350 households.
Japan is hit by around a fifth of the world’s powerful quakes every year and sits at the conjunction of several tectonic plates.
There was no damage to any of nuclear reactors in the region as they have been off-line since 2011, Japan’s public broadcaster NHK said.
Moon may be richer in water than thought — and it could help propel humans farther from earth
There may be far more water on the Moon than previously thought, according to two studies published Monday raising the tantalising prospect that astronauts on future space missions could find refreshment -- and maybe even fuel -- on the lunar surface.
The Moon was believed to be bone dry until around a decade ago when a series of findings suggested that our nearest celestial neighbour has traces of water trapped in the surface.
Two new studies published in Nature Astronomy on Monday suggest there could be much more water than previously thought, including ice stored in permanently shadowed "cold traps" at lunar polar regions.
Asymptomatic coronaagvirus sufferers lose antibodies sooner: study
Asymptomatic coronavirus sufferers appear to lose detectable antibodies sooner than people who have exhibited Covid-19 symptoms, according to one of the biggest studies of its kind in Britain published on Tuesday.
The findings by Imperial College London and market research firm Ipsos Mori also suggest the loss of antibodies was slower in 18–24 year-olds compared to those aged 75 and over.
Overall, samples from hundreds of thousands of people across England between mid-June and late September showed the prevalence of virus antibodies fell by more than a quarter.
The research, commissioned by the British government and published Tuesday by Imperial, indicates people's immune response to Covid-19 reduces over time following infection.
Early voting to be hit by heavy rain and flooding as Hurricane Zeta barrels towards the Gulf Coast
Hurricane Zeta is expected to make landfall near Louisiana's border with Mississippi on Wednesday evening as campaigns work to get supporters to the polls and convince any undecided voters to back their candidate.
"Hurricane conditions and life-threatening storm surge are possible along portions of the northern Gulf Coast on Wednesday, and Storm Surge and Hurricane Watches are in effect," the National Hurricane Center warned.
"Between Tuesday night and Thursday, heavy rainfall is expected from portions of the central Gulf Coast into the southern Appalachians and Mid-Atlantic states near and in advance of Zeta. This rainfall will lead to flash, urban, small stream, and minor river flooding," the center explained.
