earthquakes Flashcards
During an earthquake energy travels through the earth in the form of
seismic waves
Where the rocks break and where seismic energy is released
focus or hypocenter
Point on the crust of earth directly above the focus
epicenter
What are the 3 different depth
shallow, intermediate, and deep
10 to 100km
shallow
70-300 km
intermediate
300km or deeper
deep
GREATER THAN MAGNITUDE 7 and whose focus is less than 30km produce a significant movement that generates large ocean waves called
tsunami
Significant in studying earthquakes
seismic waves
2 kinds of seismic waves
primary and secondary waves
Help scientists locate the epicenter
primary and secondary waves
2 kinds of surface waves
Rayleigh and love waves
The LONGER the time interval is, the FARTHER the earthquake epicenter to a seismograph station
fact
Use to find the exact location of the epicenter
seismic information
Seismologist use the information recorded from at least three seismographic information
triangulation technique
