earthquake - how's your tank?

[BubblesandSqueak]

curious. after seeing a picture of a massive sized tank in CA, it made me think of what peoples tanks have experienced when the ground shimmies? are we just losing water over the sides or seam failures? How do your fish respond? Jumpers etc..?

Fortunately we don’t have many big ones in the UK, but hopefully everyone else affected is fine

Back a few years ago in the pacific Northwest we had a fairly big earthquake. Originally they said 7.2, but down graded it to 6.8 I believe. Any way a 6.8 is nothing to sneeze it.
I was at work in a coal generated powerhouse and it rattled and rolled like it was coming down.
It was truly scary.
Once they allowed us to leave (after head count), I raced home ( 30+ miles) and seeing the occasional house damaged, I was totally convinced my 180 gallon and 135 gallon tanks had to be destroyed, on the floor.
I actually thought I would see water draining out the front door.
When I got home, I was amazed that everything was intact and relatively safe.
Power was off on the circuit my tanks were on.
Both tanks lost 25-30 gallons of water.
The water sloshed out of the open canopy, hit the walls behind the tanks, and out. Some water hit the ceilings.
My 135 was still in the exact same spot on the stand, but the stand was 1" farther away from the wall on one end and 1/2" on the other end.
The 180's stand was still positioned where it was before, but the tank itself had moved about 3/8" off center on one end.
No fish losses, but a few corals had to be put back up in place.
Both tanks survived well. Had the 135 for 3 more years before selling it and had the 180 for another 5 years before selling it.
I'm just glad my diy stands were overbuilt. They came through with flying colors.

this is the info that I wonder about.

We had a 4.2 two days ago while I was stalking my tank...barely moved the water. Fingers crossed for anything bigger though. Realistically, I doubt you would lose much water in a 5.0-6.0.

I lived in South Bay for many years but never had a tank. Instead I had a 300 gallon koi pond on my dining room floor till the 6" fish all disappeared. I suspect the cat but never found any bones or anything. Was one of those pre-formed ponds from Lowes with a fountain in the middle.

I lived in West Seattle during that one but was in Whistler when it happened. No tank at the time but I expected to find stuff dumped out of the cupboards or something. Nothing significant was out of place when I got home.

The epicenter was near Nisqually.
At my house there was very little damage. But on the way home between the Centralia steam plant and Lacey I saw a couple chimneys knocked over and couple other random parts off houses not being where they were supposed to be.
7 miles from my house was the Safeway store my wife worked at and was there when it hit.
The final tally was they lost nearly 40% of the items that was on the shelves. Mostly glass containers.

Alaska, 2018 we had a 7.2 that was centered about 10 miles away.

I had a 220G Oceanic set up for about 8 1/2 years. Quake moved the entire tank more than 6" off the stand. Broke the drain pipes off at the bulkheads on both sides. Probably lost about 25G or so between the bulkheads draining into the stand, and the water over the rim.

I have pictures somewhere, I'll dig them up.

lil necro here but ... I am in the Thousand Oaks CA area and we just had a series of quakes at the Malibu Coast fault, which is 20 or so miles from me, starting with a 5.1 which was downgraded to 4.7... it was quite a jolt and a series of rumbles.. I just re-scaped one side of my 300G the day before and I had a couple small rocks fall which were a bit precariously balanced but that was all.. tank seems to be in the same spot.. before I put water in the tank I doubled up all of the rear 2x4s ... I figured that was about as good as I can do for the stand.

I ended up re-scaping the whole side again because I was not happy with it.. we had a series of 3.4's in the following days at the same fault and nothing moved or fell.. still was pretty unnerving thought so I finally bought a 2600w generator and am putting together a real DR plan in the event the power is out for a prolonged time. Like running a mini freezer for the frozen food even.. making sure it can all run off the generator..

Those quakes were felt in LA so I am guessing a few r2r folks felt them.. did it anyone else decided to get a DR plan together from these? I have lived in CA since 85 and never experienced so many quakes and aftershocks.. being close to the epicenters I felt anything 1.9ish or above..
