A powerful eruption at Volcán de Fuego sends a shockwave racing through the atmosphere — reaching the camera approximately 26 seconds after the explosion is seen. The delayed, gun-like blast you hear is caused by the finite speed of sound, allowing the eruption to be seen first and heard moments later.
This timing provides a clear real-world demonstration of distance. Based on the delay, the camera is positioned roughly 8 km (5 miles) from the crater, consistent with the speed of sound traveling through air (~343 m/s depending on conditions).
The eruption itself launches incandescent material high above the summit while a pressure wave propagates outward, briefly disturbing the surrounding air and producing the sharp acoustic report captured on audio.
Fuego is one of the most active volcanoes in Central America, known for frequent explosive activity. Events like this highlight the القوة of its eruptions and the dynamics of volcanic shockwaves.
Captured live from southern Guatemala.

Where is this camera?
The wonderful people at Finca San Cayetano are graciously hosting our camera at their resort. You can experience this same view in person by staying at one of their 10 luxury cabins and wake up to the sights and sounds of the majestic Fuego Volcano! Here’s their website: https://sancayetano.gt/. The camera is about 8km away from the top of Fuego. Sometimes you'll be able to hear the eruptions. Due to the speed of sound, it'll take about 26 seconds after you see an explosion before you hear it.
