Shock

________ absorbing rubber pads and springs allow buildings to sway without cracking.

Earthquakes

________ occur because of tectonic forces that assert stress on the crust.

Mercalli Scale

________: Uses Roman Numerals to rank the level of destruction for a given region.

Strike slip fault

________: Hanging wall moves sideways, stress force is shear, transform plate boundary.

Quakes

________ cause uplift of land resulting in the formation of islands and mountains.

Moment Magnitude scale

________: Most modern method of measuring total energy released by a quake.

Earthquakes

________ follow the depth of the subducting ocean plate and cause the continental plate to be uplifted during countless earthquakes resulting in mountains.

Normal fault

Hanging wall falls, stress force is tension, divergent plate boundary

Reverse fault

Hanging wall rises, stress force is compression, convergent plate boundary

Strike-slip fault

Hanging wall moves sideways, stress force is shear, transform plate boundary

Identify the magnitude where earthquakes are

a) first felt (about 2.5) b) are first considered dangerous (around 5) & c) at high end of destructiveness (6.5 and above)

Richter scale

Measures seismic waves on a seismograph

Moment Magnitude scale

Most modern method of measuring total energy released by a quake

Mercalli Scale

Uses Roman Numerals to rank the level of destruction for a given region

Historic Earthquakes

Be able to identify the location, year, characteristics and tectonic cause for each of these earthquakes
