Seismic Waves
This is the fastest seismic wave.
What is the Primary (P) wave?
This fault is caused by tension when the plates dip and slip.
What is a normal fault?
This happens when the opening in the Earth's crust releases lava, steam, and ash during and eruption?
What is a volcano?
The Richter Scale measures this about an earthquake?
What is the magnitude?
This is the sudden release of energy between two plates.
What is an earthquake?
This is the origin of surface waves.
What is the epicenter?
This is caused by compression as plates move together. The rock above is forced up and over the rock below.
What is a reverse fault?
This type of volcano is sleeping... it hasn't erupted in a long time, but it still could.
What is a dormant volcano?
The Moment Magnitude Scale takes into account these additional factors to provide a more comprehensive measurement of earthquake size?
What are fault area, movement, rock rigidity?
This is the area where rock surfaces move against each other.
What is a fault?
This wave can only pass through solids?
What is the secondary (S) wave?
This force causes a strike-slip fault.
What is shear force (plates slide past each other)?
These materials are released by a volcano during an eruptoin.
What is lava, steam, ash?
This is the strongest earthquake on the Richter Scale.
What is 10?
These is the fastest seismic wave that passes through solids, liquids, and gases.
What is the Primary (P) wave?
This is the name for the printout made by a seismograph?
What is a seismogram?
This type of fault causes the deepest earthquakes.
What is a reverse fault?
This is an area in the Pacific Ocean that has many volcanoes around it.
What is the Ring of Fire?
This scale measure observable earthquake damage and rates it using Roman numerals.
What is the Mercalli Scale?
The area on the Earth's surface directly above the earthquake's focus.
What is the epicenter?
This scale provides an accurate estimate of earthquake size.
What is the Moment Magnitude Scale?
This is a characteristic of a normal fault.
What is: caused by tension, plates move apart, rock above falls downward, dip and slip
Underwater earthquakes or volcanic eruptions can generate these large ocean waves.
What are tsunamis?
On the Richter Scale, this number and higher have the potential to cause a significant amount of damage.
What is 6.0?
This device detects earthquakes from the focus.
