Solar Impulse 2 took off from Myanmar's second biggest city of Mandalay early Monday and headed for China's Chongqing, the fifth flight of a landmark journey to circumnavigate the globe powered solely by the sun. The single-seater aircraft's team spent more than a week waiting in Mandalay for weather conditions to improve in southwestern China for what will be one of the most challenging legs of the round-the-world attempt so far. Speaking on a live feed from mission control in Monaco, Prince Albert gave pilot Bertrand Piccard clearance for takeoff.
A 7.5-magnitude earthquake struck off the coast of Papua New Guinea on Monday, US seismologists said, with "hazardous" tsunami waves possible in areas near the epicentre although no major damage was immediately reported. The quake hit at a depth of 33 kilometres (20 miles), some 55 kilometres from the nearest city of Kokopo on New Britain island and 787 kilometres from the capital Port Moresby, the United States Geological Survey said. "Based on all available data... hazardous tsunami waves are forecast for some coasts," the Pacific Tsunami Warning Centre said as a result of the quake, which was estimated earlier at 7.7 magnitude before being revised. Much smaller waves of less than 30 centimetres above the tide level could affect the coasts of other areas of the Pacific, including Australia, Japan, Philippines, New Caledonia, Marshall Islands, Fiji, Samoa, and Vanuatu, it added.
