The Ring of Fire (Pacific Ring of Fire) is an area of Pacific
Plate subduction, rimming (of course) the Pacific Ocean. The plate
subduction creates a line of volcanism geographically around its
perimeter that appears to form a circle or ring.
The Ring of Fire is the subducting plate boundary of the
shrinking Pacific Ocean. The subducting oceanic crust is being
drawn under less dense oceanic and continental crust and is melting
into the upper mantle which can lead to volcanism and
earthquakes.

Definition1/12
P waves, also called primary waves, are the first waves to be
registered on a seismograph. The S waves, or secondary waves, are
the second and slower wave to register on the seismograph. When
locating an earthquakes epicenter seismologists take the first
reading of the P wave, and then take the reading from the S wave.
At the station of where the earthquake was recorded, seismologists
draw a large circle from where the earthquakes epicenter could be.
TO exactly located the earthquakes epicenter there needs to be at
least 3 dfferent staions where the earthquake hit to determine its
epicenter using the S and P time interval.
