Group 2 Flashcards
Earthquakes are generated by abrupt rock slippages through a mechanism called——
Elastic Rebound
What theory has established that the Earth’s crust is mosaic of plates that are constantly in motion?
Plate tectonics theory
What causes ruptures in the rocks that confine the lava and gases
Volcanism
The oldest among all the scales used in measuring the intensity of Earthquake
Rossi-Forel Scale
It is the measure of energy because it calculates frictional resistance against the area of fault slippage
moment magnitude
This is the new scale used in US for measuring Earthquake’s intensity
Modified Mercalli Scale (MMI)
What is the highest intensity grade in Rossi-Forel Scale
X or 10
The rupture takes place along a plane of weakness, namely a ________
Fault
The highest grade that can be measured using a MMScale?
12
It is the measure of damage of an earthquake
intensity
