It is not my fault
A fracture, or break, in Earth's lithosphere, along which blocks of rock move past each other.
What is a fault?
Vibrations in the ground caused by earthquakes.
What is a seismic wave?
The point below the surface where energy is release in an earthquake
What is the focus?
This is the name given to the first scale used to measure an Earthquake's magnitude (the size of the seismic waves and energy moving through the Earth.)
What is the Richter Scale?
Earthquakes are caused when too much of this has built up in rocks and they can no longer handle it.
What is stress?
At this type of fault, tectonic plates scrape past each other in opposite horizontal directions.
What is a strike-slip fault
These seismic waves move half as fast as the P waves and only through solids.
What are S-waves (Secondary waves)?
The name of the location on Earth's surface directly above the focus.
What is the epicenter?
This instrument constantly records ground movement in the earth.
What is a seismometer or seismograph?
A wall of water created when an earthquake, usually a destructive margin, causes displacement of the ocean.
What is a Tsunami?
Earthquakes occur along a fault in this layer of the earth.
What is the Lithosphere (Crust)?
These seismic waves can travel through all of the earth's layers. (Solids, liquids & gasses)
What are P-waves (Primary waves)?
The locations where two pieces of lithosphere are in contact with each other and can move in different directions
What are tectonic plate boundaries?
How many seismic stations are required to locate an earthquakes epicenter?
What are 3 seismic stations?
What is aftershock?
This type of fault is found where rocks are pulling apart resulting in one block of rock sliding downward in relation to the other.
What is a Normal Fault?
These seismic waves usually cause the most damage on the surface - Love and Rayleigh waves.
What are surface waves?
Scientists can not predict the exact location of an earthquake, but they can predict what?
What is the risk of an earthquake's damage?
A scale that measures the earthquake intensity and its impact as it relates to how humans experienced it?
What is the Mercalli Scale?
The process in which shaking of the ground caused by an earthquake causes soil to temporarily become a liquid.
What is liquefaction?
At this type of fault, one block of rock slides upwards in relation to the other one as a result of them being pushed together.
What is a Reverse Fault?
The 2 directions P-waves move?
What is Push & Pull AND Back & Forth
The number of major seismic belts on Earth?
What is 3?
The most accurate scale to measure earthquake energy that is more accurate than the Richter scale because it measures the energy of waves and the ground movement.
What is the Moment Magnitude Scale?
4 examples of structural methods to create earthquake proof buildings?
What are base isolators, sheer walls, cross braces, moats, and adding support?
The place where most earthquakes occur?
What are tectonic plate boundaries?
The cause of earthquakes on Earth?
What is Stress built up in rocks?
A major area in the basin of the Pacific Ocean where many earthquakes occur?
What is the Circum Pacific Belt (Ring of Fire)
A measure of the earthquake's energy is called?
What is the magnitude?
The type of wave moves through the interior of the Earth?
What is a body wave?
The underwater mountain range located in the Atlantic Ocean where a tremendous amount of seismic activity takes place - also known as one of the 3 major seismic belts.
What is the Mid Atlantic Ridge?
When stress is released, this happens to the rocks on Earth's crust?
What is breaking and separating?
The seismic belt running through Europe and Africa near the Mediterranean Sea?
What is the Alpine Himalayan Belt (Mediterranean - Himalayan Belt)
The name of the scientist who studies seismic waves on Earth created by earthquakes?
What is a seismologist?
An area of few or no earthquakes that is surrounded by a large number of earthquakes on a diagram is called.
What is a seismic gap?
The shaking in the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
What is an earthquake?
The force exerted when an object presses on, pulls on, or pushes against another object.
What is stress?
The seismic zone in Alabama that Pizitiz Middle School sits in?
What is the Southern Appalachian Seismic Zone?
Each level of the Moment Magnitude Scale is equal to how many times greater magnitude as you move up the scale?
What is 32 times greater?
The number of seismic zones in the Southeast Region of the United States?
What is 4?
