its suppose to be "shit is hitting the fan"

mybad.

and does anyone know what's up with the volcano eruption? Any breaking news?

[jimerax]

Re: Massive 8.9-magnitude quake hits Japan

actually the magnitude moved from 7.9 to 8.4, 8.8, then 9.0.

Re: Massive 8.9-magnitude quake hits Japan

actually the magnitude moved from 7.9 to 8.4, 8.8, then 9.0.

Which shows how much we really know about earthquakes and their strength and intensity.

Re: Massive 8.9-magnitude quake hits Japan

Or people just really bad at their jobs.

Unless you're talking about the intensity of the earthquakes that led up to the big one.

I was talking about initial reports of the big one. One source was saying 9.0, then they changed it to 8.9, but it was really 9.0? :z

No, rather seismic assessments isn't a matter of obtaining accurate values immediately. It takes at least three surrounding locations to estimate the magnitude of an earthquake. Seismicities can be determined fairly well. What seismologists cannot estimate with accuracy, however, is when an earthquake will occur. And of course, that's what everyone wants to know.

Makes you wonder why people would prefer to build their houses right under the San Andreas fault, all for a nice ocean view and climate.

yeah i knew about that first part, and yeah I live in central california so I really hope not.

And wc What i was meant was, it seems like they can't accurately determine the intensity/strength very well when the go from 7.4 to 7.9 to 8.4 to 8.9 now to 9.0.

Re: Massive 8.9-magnitude quake hits Japan

I thought those scales were based on something stupid like the destruction caused afterward, which is rather arbitrary.

[Mans0n]

Re: Massive 8.9-magnitude quake hits Japan

I thought the richter scale was the common method used.. lol. And there was another one but i can't remember the name. Mercalli scale maybe?

Re: Massive 8.9-magnitude quake hits Japan

You're mixing up the Richter scale, which measures earthquake magnitude (wave seismicity), with the Mercalli scale, which measures the earthquake's intensity - the parameter being amount of destruction.

[MrGiggles]

Re: Massive 8.9-magnitude quake hits Japan

The Richter scale isn't even used anymore, they use the moment magnitude scale, both of which measure earthquakes in terms of energy released.

And wc What i was meant was, it seems like they can't accurately determine the intensity/strength very well when the go from 7.4 to 7.9 to 8.4 to 8.9 now to 9.0.

I imagine it wouldn't be uncommon to revise the magnitude of a major earthquake like this several times, especially with main shock redesignations like in this case.

Re: Massive 8.9-magnitude quake hits Japan

Just call it a 8.95 earthquake.

edit: Another explosion. How funny when they compare the nuclear explosion to the bombing they received from the U.S. in WWII.

[LJRoX]

Re: Massive 8.9-magnitude quake hits Japan

Well yeah, a nuclear explosion is equivalent to a nuclear bomb exploding... both are exploding and releasing two of what are really dangerous airborne: cesium and iodine (perhaps strontium, but not too sure)

I don't get how that's funny in anyway.
