Early last August, residents near the Lebanese port of Beirut watched in horror as one of the largest non-nuclear, human-caused explosions on record tore a chunk out of their city, leaving hundreds dead, thousands injured, and hundreds of thousands homeless.

Its shock was felt around the globe - sensors as far away as Tunisia and Germany picked up the deep rumble, and seismic stations around 500 kilometers (just over 300 miles) away recorded its tremor.

Now it turns out the Beirut explosion caused the highest layers of the atmosphere to shake, and the resulting data could inform future efforts to keep an eye on weapons testing conducted by rogue states.

Researchers from India's National Institute of Technology, Rourkela, and Hokkaido University in Japan measured electrical disturbances in the ionosphere, finding the blast was comparable to the impact of many volcanic eruptions.
