. ring of fire
The Ring of Fire is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean.
Strike-slip fault
Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally.
Normal fault
Normal Fault: In the field of geology, a normal fault is a type of dip-slip fault where the hanging wall moves downwards from the footwall.
Reverse fault
Reverse Fault: In the field of geology, a reverse fault is a dip-slip fault in which the hanging wall moves upwards, relative to the footwall.
P-waves
the fastest seismic waves and can move through solid, liquid, or gas.
. S-waves
transverse waves that travel slower than P-waves
epicenter
the point on the earth’s surface vertically above the focus of an earthquake.
focus
the state or quality of having or producing clear visual definition.
. Richter magnitude scale
The Richter scale —also called the Richter magnitude scale, Richter’s magnitude scale
explosive volcano
Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma
nonexplosive volcano
Nonexplosive eruptions are the most common type of volcanic eruptions.
. Krakatoa
Krakatoa, also transcribed Krakatau, is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung.
. Yellowstone supervolcano
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, i
San Andreas fault
The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers through California.
Mid-oceanic ridge
A mid-ocean ridge is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters and rises about 2,000 meters
