People in the northern Indian state of Punjab are reacting with awe at the sight of the Himalayan mountain range, which is now visible from more than 100 miles away due to the reduction in air pollution caused by the country’s coronavirus lockdown.

Indians in the city of Jalandhar and the surrounding area have posted photos online of the views from their homes, with some saying they haven’t seen the peaks of the Himalayas for decades.

“For the first time in almost 30 years (I) could clearly see the Himalayas due to India’s lockdown clearing air pollution. Just amazing,” Manjit Kang wrote.

The phenomenon is made possible by a dramatic improvement in air quality in recent weeks, after industries shut down, cars came off the road and airlines canceled flights in response to the coronavirus pandemic.

Delhi saw up to a 44% reduction in PM10 air pollution levels on the first day of its restrictions, India’s Central Pollution Control Board found. The PM10 standard measures airborne particulates 10 micrometers or smaller in diameter.

The report said that, in total, 85 cities across India saw less air pollution in the first week of the nationwide lockdown.

Meanwhile the air quality in Jalandhar, which sits more than 100 miles from the Himalayas, has been measured as “good” on the country’s national index for 16 of the 17 days since the nationwide lockdown was announced.
