There is science to explain that thunder
"is simply caused
by vibration of the air"
when lightening strikes at speed.
Some say
three thousand,
seven hundred
miles per hour
or in a flash
too fast to count,
too quick to measure
but not so fast
we do not run for cover, cower
and watching angry clouds
thank ancient Gods
we are not
rent asunder.
Another thunderstorm, our second in two days, hit Canberra. I wrote a poem as the rain fell.
