EARTHQUAKES AND FAULTS Flashcards
hotter than earths surface
INNERCORE
fracture in earths surface
FAULT
forms when rocks of the crust are compressed/stretched
FAULT
series of associated faults spreaded around the area
FAULT ZONE
fault that has not be active for 10,000 years/ more dangerous
INACTIVE FAULT
faults that occur more often/ less dangerous
ACTIVE FAULT
stretched a way from each other
TENSIONAL STRESS
pushed perpendicularly to the axis
SHEAR STRESS
certain piece of landmass
PLATE
what type of fault is a dipslip fault
NORMAL FAULT
forms when rocks are stretched
DIPSLIP FAULT
forms when rocks are compressed
REVERSE FAULT
forms when it makes an angle of less than 45 degees
THRUST FAULT
forced to move in parallel but different directions
STRIKESLIP FAULT
shearing and compression or tension combine
OBLIQUE STRIKE SLIP FAULT
long, narrow and usually steep sided
TRENCHES
most extensive fault zone in the Philippines
PHILIPPINE FAULT SYSTEM
marked by a break slop in between the mountains
CENTRAL MINDORO FAULT
near angat dam, santa rosa, tagaytay
VALLEY FAULT SYSTEM
how many important earthquakes in the past 1500 years
4
found between batangas/mindoro and verde island/manila trench
LUHANG FAULT
does not break from stress exertion/ returns to its original shape
KINETIC ENERGY
energy: compressional/tensional stress potential energy
ELASTIC ENERGY
rocks break around the fault, the stored energy is released/ special type of kinetic energy
SEISMIC ENERGY
