MANDALAY, Myanmar: Just after sunrise on Saturday, a satellite set its long-range camera on the city of Mandalay in Myanmar, not far from the epicenter of Friday’s 7.7 magnitude earthquake that devastated the Southeast Asian country’s second-largest city.
The mission was to capture images that, combined with artificial intelligence technology, could help relief organizations quickly assess how many buildings had collapsed or were heavily damaged and where helpers most needed to go.
At first, the high-tech computer vision approach wasn’t working.
“The biggest challenge in this particular case was the clouds,” said Microsoft’s chief data scientist, Juan Lavista Ferres. “There’s no way to see through clouds with this technology.”
The clouds eventually moved and it took a few more hours for another satellite from San Francisco-based Planet Labs to capture the aerial pictures and send them to Microsoft’s philanthropic AI for Good Lab. By then it was already about 11 p.m. Friday at Microsoft headquarters in Redmond, Washington. A group of Microsoft workers was ready and waiting for the data.
The AI for Good lab has done this kind of AI-assisted damage assessment before, tracking Libya’s catastrophic flooding in 2023 or this year’s wildfires in Los Angeles. But rather than rely on a standard AI computer vision model that could run any visual data, they had to build a customized version specific to Mandalay.
“The Earth is too different, the natural disasters are too different and the imagery we get from satellites is just too different to work in every situation,” Lavista Ferres said. For instance, he said, while fires spread in fairly predictable ways, “an earthquake touches the whole city” and it can be harder to know in the immediate aftermath where help is needed.
Once the AI analysis was complete, it showed 515 buildings in Mandalay with 80 percent to 100 percent damage and another 1,524 with between 20 percent and 80 percent damage. That showed the widespread gravity of the disaster, but, just as important, it helps pinpoint specific locations of damage.
“This is critical information for teams on the ground,” Lavista Ferres said.
Microsoft cautioned that it “should serve as a preliminary guide and will require on-the-ground verification for a complete understanding.” But in the meantime, the tech company has shared the analysis with aid groups such as the Red Cross.
Planet Labs says its satellites — it has 15 of them orbiting the Earth — have now photographed roughly a dozen locations in Myanmar and Thailand since Friday’s quake.

VATICAN CITY: A chest X-ray has confirmed a “slight improvement” in Pope Francis’s lungs as he recovers from five weeks in hospital with life-threatening pneumonia, the Vatican said on Tuesday.
The 88-year-old Catholic leader left Rome’s Gemelli hospital on March 23 after a stay in which doctors said he had almost died twice, returning to the Vatican for a convalescence of at least two months.
The Vatican press office said a chest X-ray carried out in recent days confirmed a “slight improvement” in his pulmonary infection.
Improvements were also reported in his motor skills, voice and breathing. Although he continues to use oxygen through a cannula, the Argentine pontiff can remove it for short periods.
His doctors previously said that with double pneumonia the lungs are damaged and the respiratory muscles are strained, so it can take time for the voice to return to normal.
Francis remains in the Santa Marta guesthouse, taking part in mass every morning in the chapel on the second floor where he has lived since becoming head of the world’s 1.4 billion Catholics in March 2013.
He has had no visits beyond his doctors and closest associates, the Vatican said, adding that his morale remained “good.”
The Argentine pope missed his seventh successive Angelus prayer on Sunday and there is no word on whether he will make an appearance this weekend, although another briefing is due on Friday.
The Vatican has also declined to say how the pope will participate in upcoming events for Easter, the holiest period in the Christian calendar, although it has included on its schedule the traditional “Urbi et Orbi” blessing on Easter Sunday – which only a pope can deliver.
Francis has been largely out of the public eye since he was admitted to hospital on February 14.
On the day he left the Gemelli, he appeared in a wheelchair on a hospital balcony, waving his hands from his lap to the hundreds of pilgrims gathered below to greet him.
He spoke a few words in a weak voice, saying through a microphone: “Thank you, everyone.”
He then noted a woman below with yellow flowers, and added: “Well done.”
Francis then was spotted being driven away from the hospital, a cannula in his nose.
