Earthquakes: Off The Pacific Rim or The Deep End?

If you thrilled to "angles and dangles," the series of underwater acrobatic maneuvers that skippers like CDR Rodney "Ramjet" Griffiths particularly revelled in demonstrating, you learned fairly well what a really bad earthquake felt like. If not, and you have not been a Pacific Rim dweller either, your government does not want you to be left out of a cheap, quasi- earthquake experience.

The National Weather Service has devised this virtual earthquake simulator. On that page, click the "Experience a Virtual Earthquake" button. What Richter Scale magnitude do you think is simulated?

Have you been in a submarine (regardless of depth) at the time and location of a quake, hurricane or volcanic eruption?

If you ever transited through the "Bermuda Triangle" did you receive a Compass Rose Certificate (you had to name the 32 points of the compass rose, in order). Not many got it.

I was on the recieving end of an earthquake while at sea on the USS Wahoo (SS-565) off Taiwan in the early 1970's. We were surface transiting and the boat suddenly started shuddering like we were running aground. Fortuneately our OOD (LTjg L. Loehr) was an Oceanography Major and recognized what was happening. He could see the earthquake propagating across the mostly smooth water, and rang up All Stop to stop the shafts just in case. The CO had bailed out of his stateroom and sprinted down the forward battery and said later that he heard the All Stop order, considered countermanding it to All Back Emergency, but decided to rely on the OOD as he set a new record ascending to the bridge. The navigatgor and QMOW (his career passing before his eyes) reported the depth as several hundred fathoms, with no return on shorter scales. Things settled down and we proceeded on to Keelung. There was ongoing news coverage about the earthquake in Taiwan when we got into port.

Dean, that is certainly an interesting earthquake memory alright. Later on, Wahoo trained Iranian submariners. Interesting boat wasn't she?
