Richter Scale
________- measures the earthquake's magnitude.
Seismometer
________- internal part of seismograph, a mass or pendulum mounted to a spring.
Liquefaction
________- cause soil to lose strength and flow.
Magma
________- rocks inside the volcano.
Pyroclastic Flow
________- high- speed __current of scorching gas & roc__k, creates fire along path.

Lahar
________- Indonesian word of Destructive Mudflow, prompted by strong rains or earthquake.
important cause of earthquake
Ground Shaking- most ________ damage, created by SEISMIC earth movements.
Seismograph
________- records the motion of the ground during an earthquake.
Ashfall Tephra
