The overlapped blue circles represent the output of systems placed at just 30 of these swimming pools. They would produce a whopping 48,000 gallons per minute. No hydrant system or fleet of aircraft can come close to this level of output. Assuming these 30 large pools were drained covering the blue region, this would be the equivalent of approximately 0.25 inches of rain. For a different perspective this would be the same amount of water as 750 Sikorski Firehawk helicopter drops in just 15 minutes. That’s unreal! That’s using just 30 pools. There were over 100 large pools in just this region of destruction.
The same could be said for most of the homes destroyed in Malibu. See the Google satellite image below.
