Tonga's undersea volcano causes record-breaking lightning storm.

The Hunga Tonga-Hunga Ha'apai volcanic eruption in Tonga produced the most powerful atmospheric explosion ever recorded and generated a record number of lightning strikes in a supercharged thunderstorm that lasted 11 hours and spread across 150 miles. The eruption shattered the number of lightning strikes record, producing the most intense lightning storm ever seen, with 2,600 flashes per minute at its peak and totaling about 192,000 flashes over the course of 11 hours. The lightning strikes were detected by both a network of radio antennae designed to track storms and two Earth-orbiting spacecraft.
