Tonga’s Hunga Volcano experienced a record-breaking eruption on January 15, 2022, producing the most intense lightning storm ever recorded, according to a new study published in Geophysical Research Letters. The eruption generated over 200,000 lightning flashes, with a peak intensity of 2,600 flashes per minute. The lightning provided valuable insights into the eruption’s timeline and behavior.
The eruption lasted for at least 11 hours, several hours longer than previously known. The volcanic plume reached unprecedented altitudes, with lightning flashes occurring 20 to 30 kilometers (12 to 19 miles) above sea level. The lightning appeared to “surf” giant waves that rippled through the volcanic plume, creating concentric rings of lightning centered on the volcano.
Scientists used high-resolution lightning data from four different sources to track the lightning flashes and estimate their heights. The eruption produced over 192,000 flashes, consisting of nearly 500,000 electrical pulses. Some of the lightning reached altitudes far beyond those observed in meteorological thunderstorms.

A groundbreaking study published in Geophysical Research Letters has shed new light on Tonga’s Hunga Volcano’s historic eruption on January 15, 2022. According to the study, this eruption resulted in the most intense lightning storm ever recorded. Remarkably, over 200,000 lightning flashes were generated during this event, with a peak intensity of 2,600 flashes per minute. The lightning activity offered valuable insights into the eruption’s progression and behavior.
Contrary to earlier knowledge, the eruption persisted for a minimum of 11 hours, extending its duration by several hours. The volcanic plume reached unprecedented heights, with lightning flashes occurring at altitudes between 20 to 30 kilometers (12 to 19 miles) above sea level. Fascinatingly, the lightning seemed to “surf” massive waves that traveled through the volcanic plume, producing concentric rings of lightning that emanated from the volcano’s core.
To track the lightning flashes and estimate their heights, scientists utilized high-resolution data from four different sources. These sources allowed them to identify over 192,000 flashes, consisting of almost 500,000 electrical pulses, emanating from the eruption. A remarkable finding was that some of the lightning bolts reached altitudes far beyond what is typically observed in meteorological thunderstorms.
By examining the lightning data, researchers were able to uncover previously unknown stages of the eruption. This newfound understanding not only deepens our knowledge of volcanic behavior but also adds to the intrigue surrounding Tonga’s Hunga Volcano eruption.
This remarkable phenomenon reminds us of the raw power and grandeur of nature. The awe-inspiring lightning storm unleashed by Tonga’s Hunga volcano is a testament to the Earth’s unparalleled ability to create spectacular displays.
Wow, the power of nature never ceases to amaze me! The intensity of the lightning storm unleashed by Tonga’s Hunga Volcano is truly awe-inspiring. Mother Nature’s displays of strength remind us of the immense forces at work in our world.
