Japan's meteorological agency issued a tsunami warning following a significant earthquake and placed the country on high alert for a potentially stronger follow-on quake within the next week. The agency's warning reflects established seismic science: large earthquakes frequently precede or trigger secondary events of equal or greater magnitude along the same fault systems, particularly in Japan's tectonically active zones. Authorities framed the risk window as approximately seven days, a standard precautionary horizon used in Japanese disaster preparedness protocols. The warning carries immediate operational weight for coastal communities, emergency services, and infrastructure operators across affected prefectures. Japan's disaster response framework is among the world's most developed, but a secondary quake of greater magnitude would stress evacuation infrastructure, port operations, and supply chains dependent on coastal logistics hubs. Business continuity planning for firms with Japanese manufacturing or distribution exposure warrants review. The next critical signals to watch are aftershock data from seismic monitoring networks and any formal escalation or downgrade of the agency's alert status.
Qatar's foreign ministry said mediators including Qatar, Pakistan, and Oman have reached "very progressive stages" in efforts to end the US-Iran war, pushing Brent crude down more than four percent.
Qatar confirmed it is mediating between the US and Iran but said no direct talks are currently planned. The clarification follows conflicting statements from President Trump, who claimed talks are under way, and Tehran, which denied any dialogue is happening.
Saudi Aramco reported sharply higher second-quarter 2026 profits as the Iran war restricts global oil supply and pushes crude prices up. Other oil supermajors also posted outsized earnings, raising concerns about sustained fuel cost pressure for importing economies.
President Trump called current Iran negotiations the "last chance" to end five months of conflict, pushing oil prices higher. Tehran denied formal talks are taking place, raising the risk of a diplomatic breakdown with direct consequences for global energy markets.
