Also ... Emergency Supplies to Survive an EMP.
What your electronic devices are experiencing is the after effects of something called Electromagnetic pulse (EMP).
We know that enemy nations such as Iran have discussed it's use as a pre-emptive attack on America.
Electronic systems may couple with these dangerous electric and magnetic fields resulting in damaging current and voltage surges. Further, depending on the power and trajectory of the explosion, the spread of the damage could actually reach the entire country (would take near perfect trajectory and a highly powerful weapon).
In other words, much of our electronics would be devastated. Thus, so would we.
Until a few years ago, that is.
According to Patrick Chisholm (in an October 2005 article at Military Information Technology), "a 2004 report by a panel of experts warned terrorists or other adversaries could launch an EMP attack without having a high level of sophistication, such as through short-range SCUD missile(s). Also of concern are non-nuclear, small-scale E-bombs that target localized areas."
The good thing is that there are ways to defend electronics and/ or the shelters that hold them from EMP attacks (at least to an extent). Further, the fact that our nation was once concerned about such an assault long ago would lead many to believe that our government may have some defense systems to fall back on.
Hopefully, that is.

And of course the social disorder that would follow would bring even more pain and death. In the end, those that survived, Kyle said, "would find themselves transported back to the United States of the 1880's."
That said, we certainly do have some information.
First, the EMP that would likely be generated from nuclear or E-bombs would probably pass through the protection normal consumers have against other electromagnetic interference and power surges (EMI). Thus, such contraptions wouldn't offer much help.
That said, the good news is that the military is probably far more ready to take on EMP than normal consumers. As Daryl Gerke and William Kimmel, principals at Kimmel Gerke Associates, an EMC consulting and training firm said in Interference Technology Magazine:
"Military equipment may be subjected to very high levels of RF energy (radar and radio transmitters), lightning and nuclear EMP effects. MIL-STD-461E, the key military EMC specification, addresses these multiple environments through a matrix of recommended requirements. For example, an electronic device used in a submarine will have different requirements than a device used in a helicopter."
So that's good to hear. But what about us and society at large?
2. Harden your equipment (another way of saying, protect it from EMP). Some considerations include the use of tree formation circuits (not standard loop formations), induction shielding around components, self-contained battery packs, loop antennas, and Zener diodes. In addition, grounding wires for each separate instrument into a system could help as well.
3. A new device called the Ovonic Threshold Device (Energy Conversion Devices of Troy, MI) is a solid state switch that opens a path to ground when a massive surge of EMP is encountered by a circuit. This would help in a big way.
4. Use a Faraday Box to store equipment in. Makeshift Faraday boxes can be made from metal filing cabinets, ammunition containers, and cake boxes. That said, the device you are protecting must not touch the metal container (use insulation: paper, cardboard, whatever). Further, there can be no holes. Last, if the box seems less than adequate, you may wrap it in aluminum foil for more protection.
5. Cars are already a metal box. Thus, some of them would survive, though it's reported most vehicles on the road since the mid 1960s would likely be effected. That said, gas would be a problem. So have a lot of that and food on hand (remember that refrigerators and water sanitizing devices would go out).
In the end, we don't know when or how disaster may strike. What we do know is that we need to be ready. And since an EMP attack is a stated possibility that could wreak tremendous havoc...
We need to be ready for that as well.
