The Author discusses the effect of historic exo-atmospheric nuclear explosions that created well recorded geomagnetic storms in the earth's atmosphere, and on a related peer reviewed study which determined that sedimentary rock is more conductive than igneous rock making power grids above sedimentary rock potentially more vunerable to possible power surges resulting from EMPs and Carrington events.

The Russians found out the same thing when they did they detonated a 300 kT nuclear warhead only 150 km (93 miles) above the ground. The EMP seriously damaged power lines and even got a power station in the small city of Karaganda to catch on fire.

“Earth is not the same everywhere. In recent years, researchers have been sounding Earth’s crust to determine the 3D electrical properties of our planet. These magnetotelluric surveys reveal huge variations in conductivity from place to place, depending on the mix of underlying rock.”

NB recall that one way of detecting submarines is MAD (magnetic anomaly detector) e.g. local changes to background magnetic field caused by a large chunk of steel (a submarine).
Large physical deposits of ferromagnetic material would therefore affect the local magnetic fields: which in turn has implications for EMP...

One of the Starfish detonations sizzled the electronics in Telstar, the first active communications satellite.

Starfish was hastily done as a response to the USSR’s “Tsar Bomba” test.

Directed at government agencies and I suppose the military, some low cost protections, but some are pretty easy.

Electromagnetic Pulse (EMP) Protection and Resilience Guidelines for Critical Infrastructure and Equipment Feb 2019 (Unclassified)

On 2nd page under :

Table 1. Four EMP Protection Levels for Infrastructure and Equipment

Unplug power, data, and antenna lines from spare equipment where feasible. • Turn off equipment that cannot be unplugged and is not actively being used. • Use at least a lightning rated surge protection device (SPD) on power cords, antenna lines, and data cables; maintain spare SPDs. • Have either EMP protected backup power or a generation source that is not connected to the grid with one (1) week of on-site fuel or equivalent (e.g., renewable source). • Wrap spare electronics with aluminum foil or put in Faraday containers. • Use priority phone services like GETS, WPS (for cell phones), and TSP; join SHARES if applicable (see Appendix C). • Consider land mobile radios with standalone capabilities, HF radios, and FirstNet. • Store one week of food, water, and other supplies for personnel. • Use battery operated AM/FM/NOAA radios to receive Emergency Alerts

On the last of the series Skin Walker Ranch, anomalies were found around the world where very large meteorites have struck.

Love has been one of the pioneers in applying this type of Earth data to space weather, predicting how global geomagnetic storms might affect local power lines. Now he and his colleagues are doing the same with EMPs." A little misleading...we've been studying this for years beginning the day after Starfish Prime. I know the guys who have been working this for years...Love wasn't one of them, he just picked up the thread.

If detonated over the US EMP will destroy most all electronic devices in US. Iran and N Korea would love to be the country that achieved this.

If this nuc was exploded 250 miles above the pacific where was is launched from in 1962 vandy???

Nukes will cause annihilation so what’s the point?

It is interesting to me that Enola Gay and Boxcar got away from the blasts at Hiroshima and Nagasaki with no reported circuit failures or vacuum tube damage. The pilots were instructed to 150 degrees from current course and dive to get outside the blast/ air pressure radius.

Hi Pete.

Not to hijack the thread, but has anyone heard from the pot belly dictator from the Mordor in the north?

Seems like the ronery one up and disappeared.

Back when they tested stuff without knowing what the outcome would be.

Now the Chinese do it in Wuhan.
