Interpreting the Pakistan earthquake seismogram
Look at the seismogram two blogs down. There seems to be a small blip of energy at about 11:51, 18minutes and 20 seconds after the earthquake occurred. Is this the wave arrival referred to above? Why is this blip so small compared to ...

Shaking Earth: Interpreting seismograms with travel time curves
Now look at the Lamont seismogram below. It looks to me like the first real small blip of energy that we can detect with the naked eye is at 11:51. I'm not talking abut the larger waves that arrive later, but that first small sinusoidal ...

20th Anniversary of The Earthquake Game!
Hodson said he remembers opening LSU's student newspaper, The Reveille, and seeing a photo of the seismograph reading, or seismogram. “The story is even bigger now than when it happened,” Hodson said. “To have my name tied in with that ...

Sunday again
First, Familiar with the SAC, and use it to pick up the S-wave arrival time, obtain the envelope of the velocity seismogram. Second, learn the theory of the broadening of S-wave seismogram envelope, and practice it in my code. ...

chaitén update, 3 september 2008
seismicity recorded by the puma station on 29 august, which emphasizes the presence of lp-type earthquakes (those of greater amplitude in the seismogram), combined with hb-type earthquakes. 3. findings and interpretation ...

Earthquakes, Richter Scale, and Logarithms
The other factor we need to include in an equation for the magnitude of the earthquake is the “height” (amplitude) of the lines on the seismogram. If we were measuring the earthquake at the epicenter, the higher the lines, obviously the ...

SAC(Seismic Analysis Code) question about "sgftops"
Recently, I use SAC to analyze the seismogram, but when I use the sgftops conversion utility to convert the sgf file to eps file,it always remind me" command not found". I have found some examples on internet, in these examples, ...
