Different surge protectors have different designs and components. So, some will engage at lower voltages and some at higher voltages. Be careful when buying surge protectors to check the clamping voltage. Computers and other electronic items benefit from lower (3-400V) clamping voltages.I was not home when it happened, but my girlfriend was. It was day with really high winds. She said the lights in the bedroom got really bright and she heard a pop. Thats when several breakers were tripped. The light bulbs in the bedroom were blown out.
If it was a big surge, why did it not smoke the other surge protector strips in the house?
Something is not right for sure.
Since you apparently live in an area subject to surges, I would definitely recommend both replacing all of your surge protectors, blown and otherwise, and adding a whole house surge protector. Going the extra mile to put expensive electronics behind a UPS is, in my book, cheap insurance.
1-? It all depends on how "big" the surge is (voltage and duration).How many "hits" can this take?

New Requirements for MOVs Used for Surge Suppression on AC Mains Ports - In Compliance Magazine
It is a common misconception that any product that complies with IEC 60950-1 will also comply with IEC 62368-1. A key goal of this article is to help readers of IEC 62368-1 understand the underlying safety concerns that the new requirements are trying to address.

All the best,
