Fault |
|
|
A fault that in which the hangging wall moves down relative to the footwall as a result of extension |
Normal fault |
|
|
Also called thrust. A fault in which the hangging wall moves up relative to the footwall as a result of compression |
Reverse fault |
|
|
A fault which two blocks of crust slide past each other on the same plane |
Strike- slip fault |
|
|
It can detect the existence of a fault by studying the distances between rocks |
Seismologists |
|
|
Seismic waves are classified into two |
Surface and body waves |
|
|
Waves that travel below the surface of the earth |
Body waves |
|
|
Surface waves are classified into two |
Love and rayleigh |
|
|
Its travel fastest as a speed between 4-8 at earth crust,hence there are the first to arrive at a location |
Compressional or p waves |
|
|
It can only travel through solid materials |
S waves |
|
|
Moves tranverse to the direction of thr propaganda but with no vertical motion |
Love waves |
|
|
Also called ground roll, cause rock particles to move upaward, up backward and down in the path that contains the direction of the travel waves |
Rayleigh waves |
|
|
Which happen whe. Thr shiffting of earth plates are driven by the sudden release of energy within some limited region of the rock |
Tectonic eartquake |
|
|
The roughness or harshness along the faults |
Asperities |
|
|
The places where the rupture slows or stops are termed |

|
|
This phenomeon often occurs in volcanic regions and can serve as an early warnings of volcanic eruption |
