Comparative Energy Released By Two Earthquakes
As with the Richter scale, an increase of one step on this logarithmic scale corresponds to a 101.5 ≈ 32 times increase in the amount of energy released, and an increase of two steps corresponds to a 103 = 1000 times increase in energy.
The following formula, obtained by solving the previous equation for, allows one to assess the proportional difference in energy release between earthquakes of two different moment magnitudes, say and :

Famous quotes containing the words comparative, energy, released and/or earthquakes:
“The utmost familiarity with dead streams, or with the ocean, would not prepare a man for this peculiar navigation; and the most skillful boatman anywhere else would here be obliged to take out his boat and carry round a hundred times, still with great risk, as well as delay, where the practiced batteau-man poles up with comparative ease and safety.”
—Henry David Thoreau (1817–1862)
“Reckoned physiologically, everything ugly weakens and afflicts man. It recalls decay, danger, impotence; he actually suffers a loss of energy in its presence. The effect of the ugly can be measured with a dynamometer. Whenever man feels in any way depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with the ugly, they increase with the beautiful.”
—Friedrich Nietzsche (1844–1900)
“the walk liberating, I was released from forms,
from the perpendiculars,
straight lines, blocks, boxes, binds
of thought
into the hues, shadings, rises, flowing bends and blends
of sight:”
—Archie Randolph Ammons (b. 1926)
“For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places: all this is but the beginning of the birth pangs.”
—Bible: New Testament, Matthew 24:7,8.
