Some of our SCADA architectures will protect data lines on the edges of a nuclear (Hight altitude) EMP (but don't quote me on this). The E2 component of the pulse is the easiest to protect against, and is kind of like the pulse produced by lightning. The E3 component of the pulse is a very slow pulse, and may last several minutes. This one can be caused by the nuclear detonation pushing earth's magnetic field out of the way or a Solar Event. The E3 is much like a geomagnetic storm caused by a very severe solar flare.
Google the 1859 Carrington Event for more about an E3. NASA has a pretty good article about this event. Some scientists believe we are due for another one of these SUPER SOLAR events, within the next two years. Now the Carrington Event had little effect on the infrastructure of Europe and North America simply because we were in the early stages of technological development of the 19th century and the only real effects were telegraph lines being influenced. Because (most) modern electronics are not insulated against this type of event, the effects are speculated to be catastrophic. This has a subject of record back in 2005. The following is a quote from a House debate on EMP effects in the US.
[Congressional Record: June 9, 2005 (House)]
This likely consequence of a high-altitude nuclear burst was
corroborated by Dr. Lowell Wood, who in a field hearing at the Johns
Hopkins University applied physics laboratory, made the observation
that a burst like this above our atmosphere creating this
electromagnetic pulse would be like a giant continental time machine
turning us back to the technology of 100 years ago. It is very obvious
that the population of today in its distribution could not be supported
by the technology of 100 years ago. And I asked Dr. Wood, I said, ``Dr.
Wood, clearly the technology of 100 years ago could not support our
present population in its distribution,'' and his unemotional response
was, ``Yes, I know. The population will shrink until it can be
supported by the technology.''
Just a word, Mr. Speaker, about what this EMP is. It is very much
like a really giant solar storm. All of us are familiar with solar
storms and with the disruption to our communication systems. And this
is like a really giant solar storm. It is kind of like really intense
static electricity everywhere all at once, all over the whole country.
It is sort of like a lightning strike that is not just isolated to one
spot. Different than a lightning strike in terms of the intensities and
so forth and the spectrum, but it would be everywhere all at once over
a very large area.

The average Joe wanting to protect sensitive electronics has only one choice. Build a Faraday cage or Field expedient Faraday cage. The data I have suggests that putting your stuff under ground will not provide protection. The pulse will go into the earth deeper than you can dig. The only thing one can do is direct this energy around your device or devices. (Faraday)...
Building one is not too difficult, grounding is also important. There are several valid sources out there for building your own Faraday. I have a working Faraday, but am looking into the possibility of using a microwave as a "reverse" faraday...
Regarding vehicles. As far as I am concerned, any newer vehicle is subject to the effects of an EMP Event. This is proven by way of the new Law enforcement technology for disabling vehicles using small scale EMP generators. Unless you own a 1968 Mustang plan on some form of Bipedalism...
Oh... I forgot.. Regarding Solar EMP Events: Data suggests they do not have an effect on humans. They will not cause "atmospheric" fires other than an aurora borealis as indicated in the Carrington Event.
Regarding the above mentioned book "One Second After".... Excellent read on the societal effects of an EMP... Although I slightly disagree with the authors employment of the EMP event in the book, I do believe he hit the nail on the head on its after effects. I believe we are more likely to be hit with a Solar EMP than a Nuclear EMP.... SDI is alive an well... thank you Ronald Reagan
