Explain the focus and the epicenter?

the focus is below the epicenter. the epicenter is where the focus is but on the surface. the focus is below the surface, it ranges in the depth. they show you the epicenter on the news, not the focus.


How do scientists work out the epicentre of an earthquake?

S-waves and P-waves emit from the focus (epicenter) at the same time, yet one of them is faster than the other. therefore the S waves and P waves are directly proportional to each other. So all one needs is to do the math and trace the distance between the waves and there, you have found the Focus (epicenter) of the earthquake.


Briefly describe how the epicenter of an earthquake is located?

With the help of seismograph you can find arrival time of secondary wave and primary wave. The difference in time in seconds multiplied by 8 will give you the distance of focus the starting point of earthquake. Even though the speed of these waves differs according the geographical condition the difference in speed is almost constant and it is 8 k/m per second. Therefore you can draw a circle from that station .The focus point should be some where on the circumference of the circle. When you get the data from other seismic station you can draw another circle from that station that will cut the previous circle in two points .One among the two point must be the focus point. When you draw the circle in the same way from third station this will pass through one among the two meeting point of the previous circles. This point is focus.The imaginary point just above focus on earth is the epicenter. To have clear idea about this visit my slide show .I have also found a new method to find the epicenter from single station using my direction finder to gether with seismograph.It is approximate quite enough to issue Tsunami warning. I have issued the warning 2 hours before Tsunami struck our Indian coast but it was ignored. My web site . please be patient to down load .


Will we have an earthquake tomorrow?

No.. there is not going to be an actual earthquake, they are carrting out a drill, to show people how to prepare for a big earthquake if it were to ever happen. use the link to find out more check out here http://www.ocregister.com/articles/earthquake-quake-drill-2226277-orange-thursday


What diagram is used to show wind speed and direction?

A wind rose diagram is used to show wind speed and direction. It consists of a circular plot with different sections representing wind direction and the length of the lines or petals indicating wind speed.

What do geologists use to locate a earthquakes epicenter?

The S-P time method is perhaps the simplest method seismologists use to find an earthquake's epicenter. +++ No it's not. That finds its Focus. The Epicentre is the point of maximum movement on the land surface above the slip itself.


Ford Focus fuse diagram?

A Ford Focus fuse diagram will show the placement of all fuses for the vehicle including the brake and headlights, the interior lights, and the dashboard lights. This diagram is generally located on the inside cover of the fuse box.
