THE AREA WHERE SLIPPAGE FIRST OCCURS ALONG A FAULT
WHAT IS THE FOCUS?
A SERIES OF SMALL TREMORS FOLLOWING AN EARTHQUAKE
WHAT IS AN AFTERSHOCK OR MICROQUAKE?
90% OF CONTINENTAL EARTHQUAKES HAVE THIS KIND OF FOCUS WHICH ALSO CAUSES THE MOST DAMAGE
WHAT IS A SHALLOW FOCUS?
MOST QUAKES OCCUR NEAR THESE
WHAT IS A PLATE BOUNDARY?
ACCORDING TO THIS THEORY ACCUMULATED STRESS CAUSES ROCK TO DEFORM OR FRACTURE AND THEN SPRING BACK INTO THEIR ORIGINAL SHAPE CAUSING AN EARTHQUAKE

IS USED TO DETERMINE THETHIS KIND OF GRAPH IS USED TO DETERMINE THE EPICENTER OF AN EARTHQUAKE
WHAT IS A DISTANCE TIME GRAPH?
TO DETERMINE HOW FAR AWAY FROM A SEISMOGRAPH STATION AN EARTHQUAKE OCCURRED, SCIENTISTS PLOT THE DIFFERENCE BETWEEN THESE 2 WAVES
WHAT ARE P & S WAVES?
THIS IS AN APPROXIMATE MEASURE OF HOW MUCH ENERGY THE EARTHQUAKE RELEASES
WHAT IS THE MAGNITUDE?
A MAGNITUDE OF 2.5 OR LESS, WHICH CANNOT BE FELT BY PEOPLE
WHAT IS A MICROQUAKE?
VALUES FOR THE MAGNITUDEDAILY DOUBLE!!!!!!!!!! THIS SCALE PROVIDES VALUES FOR THE MAGNITUDE OF AN EARTHQUAKE
WHAT IS THE RICHTER SCALE?
THESE WAVES CAUSE THE MOST DAMAGE
WHAT ARE SURFACE WAVES?
A 7 OR ABOVE ON THE RICHTER SCALE
WHAT IS A MAJOR EARTHQUAKE?
THESE WAVES ARRIVE FIRST ATA SEISMOGRAPH STATION
WHAT ARE PRIMARY, OR P WAVES?
THESE WAVES CAN ONLY TRAVEL LITHOSPHERE, OR ANY SOLIDTHROUGH THE LITHOSPHERE, OR ANY SOLID
WHAT ARE SECONDARY WAVES,OR S WAVES?
THESE ARE COMPRESSION SEISMIC WAVES
WHAT ARE P WAVES?
THESE WAVES ARE THE LAST RECORDED AT A SEISMOGRAPHTO GET RECORDED AT A SEISMOGRAPH STATION
WHAT ARE SURFACE WAVES?
SEISMIC WAVES CAN BE GENERATED THROUGH EARTHQUAKES ON THE OCEAN FLOOR WHICH CAN CAUSE THESE
WHAT IS A TSUNAMI?
Earth Science Fall Earthquake- vibration of the earth’s crust Usually occur when rocks under stress suddenly shift along a fault.
