The first waves to arrive at a seismograph station are primary waves, or P waves.
The last seismic waves to arrive are surface waves.
The biggest earthquake in our century is the Indian Ocean earthquake in December 2004 with a magnitude of 9.1. But that's not exactly in the last five years, so the Sendai earthquake in Japan today (March 11, 2011) is the biggest earthquake in the last 5 years, with a magnitude of 8.9.
Because of the 8.8 earthquake in Chile last week.
it last nearly for four minutes
The first waves to arrive at a seismograph station are primary waves, or P waves.
Some good questions about earthquakes are:What is an earthquake?How long do earthquakes last?Is there an 'earthquake season' or 'earthquake weather'?Where is the safest place to be in an earthquake?Will the ground open up during an earthquake?What is a seismometer, seismograph, and a seismogram?When was the seismograph invented?What is the Richter Scale?Do many small earthquakes prevent larger earthquakes?Can we predict earthquakes?What is liquefaction?
A surface wave is the last seismic wave to arrive after an earthquake.
seismic waves
The last seismic waves to arrive are surface waves.
According to the US Geological Survey, each state has some. Florida and North Dakota have fewer than the other states but Florida has more hurricanes. The last earthquake in Florida was in 1952 and the last earthquake in North Dakota was 1968.
Earthquakes occur in the New Madrid seismic zone every day. Most of them are so small (magnitudes 0, 1, 2...) that they can't be felt, only recorded by an instrument. The faults in the New Madrid seismic zone are active, producing these small events all the time. If you mean Madrid, Spain, you can do an earthquake search by googling "international seismological centre".
Missouri lies on the second largest fault line in North America. This fault line is over twenty years past due for major seismic activity. The last great earthquake in Missouri was so violent that it created East St. Louis.
a siesmograph is a graph that tells the power of an earthquake. it uasually takes track from the last earthquake and now it trys to find out what the next earthquakes power would be like and to try to see when it may occur sometimes it could be accured or not but that is a seidmograph.
in the earth
i think it was when the earthquake happened last year
