Two weeks ago, at 4:45am, we had the mother-of-all lightning strikes. I was looking at my clock when it hit. It was like striking an arc with no welding helmet while standing next to an M1 Abrams tank at the range. At first, we thought the windmill got hit, but it was still turning. I went out to see if the house, propane tank, or any other building got hit. Odd thing, there was no power outage, clocks weren't flashing, but then, we started to find damage. Total loss came to: 2 computer motherboads, a modem, a router, a bridge repeater, a wireless card, a satellite receiver, and a wall phone jack.
One computer was cabled to the router, which was cabled to the modem. We have DSL, so the modem was cabled to the phone jack. All those connected items cooked. Here's where the lightning intensity shows. The wireless bridge repeater is in another building, cabled to a computer. The repeater stayed on, but the networking circuit cooked, The computer is fine. One of the computers was also wireless, but the wireless card and the network circuit on the motherboard cooked. The computer itself runs fine, but has no networking. One of two satellite receivers cooked. We do have a whole house surge protection installed, but that didn't trip. The local phone company lost the main box at the end of our road, took 4 days to get service back. No neighbors suffered damage. They're 1/4 mile away.
We now have APC and Tripp Lite surge protectors throughout the house, and we still haven't found where the strike was. Neighbors said it was on our property.

Lightning can do strange things!
I'm retired now,but a lifelong electrician and have seen a lot of damage from it over the years.
If the pic works,here's my gatepost light and motion detector.



Lightning blew the light off and blew the bulbs out of the detector.It also shattered the plastic post,which is filled with concrete and rebar.This is a long way from our house,but we still lost the router,my computers power supply,the doorbell trans and some breakers tripped.The fridge compressor went out a short time later so,maybe some collateral damage too! Neighbor said it sounded like a bomb went off!Had 3 other big strikes here at home!

Depending on the polarity of the strike, the damage may or may not be readily apparent. When you get a strike that goes from earth to cloud (yes, a real thing), the earth voltage goes up, taking the grounding system voltage up with it. Electronic stuff doesn’t like that.

Glad to see only property was damaged and there were no injuries. Have you checked with your insurance agent/carrier as possible coverage there.

Not only is lightning coming from the ground a real thing, all of the lightning you can see reaching the earth comes from the ground up. The part you can see anyway.
