I'm not absolutely sure, but those look to be 345-kilovolt lines. Judging from the multiple cables used and your testimonial about the lines audibly buzzing, it's likely a safe bet that the lines were built to carry a heavy load (carrying as much energy as they could carry). That would lead me to expect that standing under the lines like that was not a good idea.
One handy way to determine the electromagnetic footprint of power lines is to use a radio set to AM (either driving under the lines in a vehicle or walking near them with the use of a handheld radio) and listening for how much static. The more interference you hear, the more powerful the footprint must be.
My father told the story of working as a building trades carpenter on a main substation project, maybe 20 year ago, give or take. An equipment operator was running a large trackhoe excavator on the project site, sitting directly beneath a set of 230-kilovolt power lines for a considerable period of time. The operator worked until he was done, either the end of his shift or maybe break time, and got down off the machine where he had worked. The man was dead the instant he touched the ground. Apparently, the stray voltage from the overhead lines directly above him had energized his machine, and when he stepped down to get off the machine, he completed his own circuit, electrocuting himself immediately. The take-home point: never park under or linger beneath high-voltage lines.
That having been said, that is a very interesting photo. Well done.
