Japan tsunami warning latest as people told to avoid the coast after 7.5-magnitude earthquake

• Japan initially issued tsunami warnings for its eastern coastline following a major 7.5-magnitude earthquake in the Pacific Ocean.
• The earthquake, with an epicentre 100km east of Miyako in Iwate prefecture, prompted warnings for waves up to three metres in Hokkaido, Aomori, and Iwate.
• The Japan Meteorological Agency later downgraded these warnings to advisories, indicating a likelihood of waves up to one metre.
• Despite the downgrade, residents were still advised to stay away from coastal areas, and the first tsunami waves, including a 40 cm wave at Miyako port, reached Iwate prefecture.
• Officials also issued an advisory for northern coastal areas regarding a one per cent chance of a mega-quake in the coming week, urging preparedness.
