AI Thread Summary
It is possible to estimate the characteristics of a lightning bolt using the sound of thunder, specifically by measuring the time of arrival of the first sound and the duration of the thunder. This allows for the determination of the distance to the lightning strike and provides a minimum length for the lightning channel. The pitch of thunder, typically around 50 cycles per second, can also be analyzed to calculate the energy input per unit length of the lightning stroke channel, which ranges from 100,000 to 1,000,000 watt-seconds per yard. Factors such as air density, altitude, and proximity to the strike influence the pitch of thunder, with closer strikes producing sharper, higher-frequency sounds compared to distant, lower-frequency rumbles.

If given the decibels from the thunder and the distance away the lightning struck, would it be possible to tell the amount of electricity in that bolt of lightning? If so, a formula would be much appreciated.

Apparently decibels don't figure into it.

After consulting Martin A. Uman's basic reference book on lightning, I summarize the following:

From measurement of the time of arrival of the first sound of thunder we can determine the distance to the closest point of the lightning channel.

From the thunder's duration we can determine a minimum length for the channel.

Generally the pitch of thunder is 50 cycles per second. From measurement of pitch and use of appropriate theory, scientists have determined the energy input per unit length of lightning stroke channel (100,000 to 1,000,000 watt-seconds per yard of channel length).

Thunder pitch is also influenced by air density and altitude.

... and proximity ! :smile:

the closer it is the sharper and higher frequency the crack. compared to long distance low frequency rumbles

These last days, there is a seemingly endless cluster of rather powerful earthquakes close to the islands of Santorini, Amorgos, Anafi, and Ios. Remember, this is a highly volcanically active region, Santorini especially being famous for the supervolcanic eruption which is conjectured to have led to the decline of the Minoan civilization: https://en.m.wikipedia.org/wiki/Minoan_eruption To grasp the scale of what is happening, between the 26th of January and the 9th of February, 12000...
