Epicentre
Where the earthquake actually appears on the earth’s surface, sometimes there is a rupture at that point
Epicentre
Downslope creep driven by sequential freezing and thawing
Gelifluction
A huge collapse depression at the Earth’s surface that sank into a near-surface magma chamber during eruption of the magma
Resurgent Caldera
The length of a fault broken during an earthquake
Surface Rupture Length
Developed in 1902 by Giuseppe Mercalli
Mercalli Intensity Scale
Measure earthquakes quantitatively, independent of location and assigns a magnitude value based on energy released
Magnitude Scale
Involves the movement of a slab of rock, debris, or cohesive mud as a single unit
Slide
The time between seismic waves
Period
Extremely rapid downslope movement of large volumes of rock and debris
Sturzstrom
Secondary/Shear waves that shake back and forth perpendicular to the direction of wave travel, cannot travel through a liquid (4.5km/s upper mantle, 3.5km/s crust)
