Tsunami warnings scaled back across northern Pacific

This BBC Global News Podcast episode covers several major world events. It begins with the report of a massive earthquake off Russia's far eastern coast, triggering tsunami warnings across the Pacific. The podcast then shifts to the Gaza Strip, reporting on the increasing number of hunger-related deaths and the challenges of delivering aid to the region, along with the increase in attacks on Palestinians in the occupied West Bank by Jewish settlers. The episode also discusses Greece's controversial decision to detain migrants arriving on small boats from North Africa and the concerns about environmental protection rollbacks in Brazil. Finally, the podcast highlights South Africa's efforts to combat power cuts with pay-as-you-go backup power systems and introduces the UK's first female Astronomer Royal, and concludes with a tribute to the late Ozzy Osbourne in his hometown of Birmingham.
