When a sudden, mass power outage recently struck Spain and Portugal, it took many by surprise and had experts scrambling for explanations, as per a report. Spain's Prime Minister, Pedro Sánchez, attributed that the outage had resulted from a "strong oscillation," but warned that no conclusions about the cause could be determined yet, according to a Weather.com report.This massive blackout has led many Americans to wonder: could it happen here? AccuWeather meteorologist Dan DePodwin explained the process and said it could happen in the United States, as per USA Today. During an interview with USA Today, DePodwin said that rapid changes in temperature or wind speed or a long period of extreme temperatures can lead to what he called "induced atmospheric vibrations," as per the USA Today report.DePodwin said, "The atmosphere does something to induce vibrations in power lines, which can lead to outages," as quoted by USA Today. He said that it can occur "anywhere there are transmission lines," which also includes the United States, reported USA Today.The United States gets electricity from three large grids, the Eastern Interconnection, the Western Interconnection, and the Texas grid, as per the Independent. They are linked to local networks, which are often outdated and under more pressure from escalating demand and severe weather, as per the report. Even with attempts to update them, dangers, from space, the climate, and cyberspace, remain on the rise, according to the Independent.Brian Stone, director of the Urban Climate Lab at the Georgia Institute of Technology said, 'I think it's an absolute certainty that we will have an extreme heat wave and an extended blackout in the United States,' as quoted by the Independent.The consequences of such an outage are immense. In America, where much of life hangs on continuous power, from communication networks to public transit to hospitals, a sudden blackout across several states could be disastrous. Traffic systems would come to a standstill, air conditioning equipment might fail in the heat, and hospitals would have to rely on backup generators.They can be caused by "induced atmospheric vibrations," which happen during sudden changes in temperature or wind speed.Yes. Experts say the atmospheric conditions that triggered the Spain and Portuga blackout could also affect American power lines.

This is because the seismic waves from shallow earthquakes have a shorter distance to travel to the surface, resulting in stronger ground shaking and potentially more damage to structures and greater Tibetan Plateau is known for its seismic activity due to tectonic plate and Nepal lie on a major geological fault line where the Indian tectonic plate pushes up into the Eurasian plate, and earthquakes are a regular occurrence as a result of it. The region is seismically active due to tectonic uplifts that can grow strong enough to change the heights of the Himalayas' downpour in Tibet early on Wednesday morning triggered flood in rivers flowing in Nepal, prompting authorities to issue warning in three district of Rasuwa, adjoining the Tibetan side which was hit by a flash flood on July 8 had claimed seven lives with over a dozen still missing, after Lhende River swept infrastructure near Nepal-China rainfall in Tibet earlier this morning has triggered flooding in the Trishuli River, raising water levels in areas around Uttar Gaya in Rasuwa and the Trishuli 3B Hub in Kispang. Authorities have issued warnings as water flow continues to rise in the Rasuwagadhi area.

More details are awaited. (ANI)
