4 cards from this section. Quick, good the night before a test.
What does the Richter scale measure?
Think about what happens during an earthquake.
Who developed the Richter scale?
Consider whose name is associated with this scale.
What is the maximum amplitude related to in the Richter formula?
Remember what contributes to the Richter calculation.
The Richter scale is effective for earthquakes with magnitudes up to:
Think about the threshold for reliable measurements.
An earthquake measurements indicate a maximum amplitude of 400 mm. Calculate the magnitude of the earthquake using the Richter formula if A0 (standard amplitude) is 0.1 mm.
Use the logarithmic properties to simplify the values.
If a 5.0 magnitude earthquake releases a certain amount of energy, calculate the energy released in Joules for a 7.0 magnitude earthquake.
Remember the relationship of energy release for every magnitude increment.
