Earthquake! (MERGED THREADS)

[BecciBoo]

The following quote is from staff at Exploraquarium in Washington state when asked if you could feel earthquake activity on a ship in the ocean:

Larger earthquakes can be felt in the water. And though I am not a fish, ... You would only feel the large earthquakes that happened nearby.

 

So according to this authority, you can feel it!

Just what authority have you dkalnas?

My wife and I were on the Valor last week and we did feel something around 4:30 AM. It was a violent shaking of the ship. We are not sure what it was but it woke us and lasted some 15 seconds or so. Not something we have ever felt on any other ship.

Does anyone know if there were any cruise ships docked or nearby when the quake hit?

 

The Carnival Valor had just left Roatan that day and YES we felt the earthquake.

How were you able to tell the difference between the earthquake and the constant movement of the ship in water?

Try googling these terms if you want some background on how energy is transmitted through water. You'll probably learn a lot about sonar and depth charges along the way if you hit a WW2 site that deals with submarine hunting and underwater explosions.

 

Explosion/eruption/earthquake=sound is transmitted much further by water than through air. And when you have a huge metal-skinned vessel, this makes a great receiver/sounding board for picking up a broad range of sound energy travelling through the water. Motion energy is expended in the path of least resistance, mostly up, but if the energy is large enough, the sideways motion can be quite large--note the tsunami watch in the aftermath of earthquakes.

 

And please don't feed the trolls--they keep coming back for more.;)
