the
7 July 2005 London bombings were initially attributed to Power surges. Can any expert explain how bomb explosions can be mistaken for power surges? Have power surges more often been so severe as to account for destroyed trains and injured passengers? Thanks, —

Power surges occasionally cause
transformers to explode, and that can be just as dramatic as a chemical explosion. I'm reminded of a few years ago when a pole-top utility transfomer exploded about a mile from my house...
I was in the computer bunker of one of London's video control rooms at the time of the bombings. There was indeed a power surge, but it was after the first explosion and it was the result of the security forces commandeering our systems with an intensity far exceeding our normal traffic monitoring requirements.

Verification and editing if necessary request
Can some expert verify the causes of transient voltage spikes. It seems to me that main causes are lightening strike, inductive spikes and followed by disturbances in the major power supplying infrastructure. To me it seems the spikes by MCB trip etc. are more or less part of the inductive spike.
What's the differenxr between "fast" and "short duration"?
In the current definition of "spike" in this article, it is stated twice that spikes are "fast, short duration transients." But what's the difference between a short duration signal and a fast signal? Moreover, what does it even mean a fast signal (e.g. "fast voltage")?
