Participant“Any engineering types here want to guess at how it compares to a nuke going off.”
Interesting exercise. With Google/Wiki nobody has to guess or even be an engineer.
Wiki gives the formula for explosive energy as a function of magnitude (x) as (10^(x))^(3/2) in kg of TNT. That means a 7.2 quake is 63.1 megatons of TNT explosive equivalent.
According to Wiki, the largest U.S. nuke is up to 1.2 megatons TNT equivalent. The Trident missile warheads are each .475 megaton.
So my answer is around 52 of the big nukes or 132 Trident warheads or 16 1/2 Trident missiles if we are talking the treaty limit of 8 warheads per missile.
The article notes that most of the energy of an earthquake is absorbed by the crust and not transmitted to the surface (which would explain why shallow quakes are more destructive than deep quakes of the same magnitude). On the other hand, much of the energy of a nuke is transmitted to the surface. That is kind of the point of the weapon.

ParticipantNavy moves (and I assume all DOD moves) can either use the full service movers or Do-It-Youself (DITY). I have chosen the DITY for 3 of 4 of my PCS moves because you make money on it (and I am a lot more careful with my stuff than the movers). The military will pay you a percentage of what it would cost for the full prices movers (based on your household goods weight). You aren’t payed 100% and I can’t remember offhand the actual percentage but it is an incentive to save the Navy a few dollars. If I can rent a U-Haul and pay for gas and all expenses cheaper than what the Navy will pay, I pocket the difference.
The Navy recently is in the process of closing the base in Ingleside, Texas. I believe most of the minesweepers stationed there have moved to San Diego but I don’t know how many total personnel might have recently arrived.

ParticipantTo be clear, I’m paying for the windows through US Window and Door. I am not buying direct from Milgard.
I am paying $442 each for the 6 single casement windows (forgot to mention they have the grid between the glass). $305-350 for the 3 sliders. Actual install I believe is 1125 (this is the amount not taxed on the estimate). On top of this there is a $30 per window mail in rebate (prepaid debit card) from Milgard. They changed the offer to $20 per window recently.
