Focus / hypocentre
Epicenter
____is perpendicular ____
Epi,hypo
3types of waves
P,S,L
1st wave to travel from focus or hypocenter
P wave
2nd wave to travel from focus or hypocenter
S
Surface wave also known as
L wave ( P+ S)
P wave can travel through
Solid > liq> gas ( max speed solid )
P wave also called
Primary wave
S wave also called
Secondary wave
P wave is ____ wave ( transversal or longitudinal)
Longitudinal
S wave is a ___ type of wave
Transverse
P wave travels faster , y
It’s longitudinal so travels faster + 1 St to reach surface
L wave known as
Surface wave or body waves
Most destructive wave
L
S wave doesn’t passes through
CORE
S wave travels through only
Solid
Last wave to reach
Surface/ body / L wave
Which wave travels only on surface
