A new volcanic eruption in south-west Iceland has led to the evacuation of Grindavik and the Blue Lagoon spa. The eruption, the fifth since December, began near Sundhnuksgigar on the Reykjanes Peninsula, with a fissure over 2.5 km long. A state of emergency has been declared as lava, described as larger in volume than recent eruptions, threatens Grindavik. Most residents had already evacuated in November, but some resisted the latest orders. The Svartsengi power plant and local power have been shut down as a precaution. Officials warn of ongoing volcanic activity that may last for decades.

The India Meteorological Department (IMD) is examining the 52.9°C temperature recorded at Delhi's Mungeshpur Automatic Weather Station, suspecting a potential sensor error. Earth Sciences Minister Kiren Rijiju noted that the reading is unofficial and likely erroneous, urging verification. The Safdarjung center, Delhi’s official temperature source, recorded 46.8°C. The IMD highlighted that no other stations reported temperatures above 50°C, with most readings ranging between 45.2°C and 49.1°C.

Measures include rationing water supply, reducing frequency in some areas, and reallocating saved water to deficient zones. With Delhi heavily reliant on Haryana and Uttar Pradesh for water, Atishi threatens Supreme Court action if the issue persists. As the heatwave intensifies, cooperation and judicious water use become imperative for residents.
