How earthquake ready is your tank? While I was visiting forums and sites in front of my computer I was surprised by a soft up and down jolt in my chair. Quickly looking at my tank the corals were SHAKING! It was an earthquake, rather strong one around 4plus in RS and lasted about a half a minute. This occured twice the past month. The last was 4.5 RS and my tank survived. I wonder until when. It's a good thing the stand was over designed I guess. But the tank walls might not be able to stand it for long. ps. my location - quezon city, philippines. another earthquake and typhoon belt. too bad!
