Thunder forms when lightning heats the surrounding air to over 30,000°C. This rapid heating causes the air to expand explosively, creating shockwaves that manifest as the rumbling sound we call thunder.

Lightning and thunder happen simultaneously, but light reaches our eyes faster than sound reaches our ears. This explains why you always see lightning before you hear thunder, even though they occur together.

To estimate how far lightning is, count seconds between the flash and the thunder. Each five-second interval equals roughly one mile, offering a simple yet effective way to gauge the storm's proximity.

While thunder itself poses no danger, it signals lightning nearby, which can be deadly. If you hear thunder, you're close enough to be struck by lightning, so always take cover immediately during a storm.

Thunder’s volume depends on your distance from the lightning strike. Close by, it can reach 120 decibels, as loud as a rock concert. Farther away, it becomes a low rumble due to sound dispersion.

The shape and density of clouds influence how thunder echoes. Dense storm clouds create sharper, more intense sounds, while thinner clouds produce rolling, muffled rumbles that travel farther.

Thunder-like sounds can arise from non-lightning events. Volcanic eruptions, nuclear detonations, and even meteors create shockwaves in the air, mimicking the booming roar of a thunderstorm.

When lightning strikes water, the intense heat and pressure create shockwaves that produce underwater thunder. While muffled, it demonstrates how lightning’s power extends beyond the sky.

Different types of lightning create unique thunder sounds. Cloud-to-ground strikes result in sharp cracks, while cloud-to-cloud flashes produce rolling rumbles, offering clues about a storm’s behaviour.
