Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Fault Rupture Aspect Ratio to answer this question: calculate rupture length-to-width ratio from rupture length along strike and rupture width down dip? Enter rupture length along strike and rupture width down dip; the calculator shows rupture length-to-width ratio. For example: rupture length along strike=80 and rupture width down dip=20 produce rupture length-to-width ratio=4. The answer tells you rupture length-to-width ratio.
Age 15Explain it to a 15-year-oldConnect it to the formula
Fault rupture aspect ratio compares mapped length along strike with rupture width down dip. This page evaluates the relationship directly. The rule is c=a/b. Its input values are rupture length along strike, rupture width down dip, and the main result is rupture length-to-width ratio. For example: rupture length along strike=80 and rupture width down dip=20 produce rupture length-to-width ratio=4.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated fault rupture aspect ratio relation over the valid real-number domain stated below. The implemented relation is c=a/b, evaluated from rupture length along strike, rupture width down dip to produce rupture length-to-width ratio. Fault rupture aspect ratio compares mapped length along strike with rupture width down dip. This page evaluates the relationship directly. Use the same rupture model and distinguish surface trace, subsurface rupture, projected width, and true down-dip width.
Inputs and valid domain
- rupture length along strike must be a finite real number.
- rupture width down dip must be a finite real number.
Important boundary: Use the same rupture model and distinguish surface trace, subsurface rupture, projected width, and true down-dip width.
The formula
c=a/b
How the calculator works through it
It substitutes rupture length along strike, rupture width down dip into the formula and exposes every numerical step above. The main output is rupture length-to-width ratio.
Read the result correctly
The rupture length-to-width ratio is the direct answer to “calculate rupture length-to-width ratio from rupture length along strike and rupture width down dip.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
rupture length along strike=80 and rupture width down dip=20 produce rupture length-to-width ratio=4.
Where this model stops being reliable
Use the same rupture model and distinguish surface trace, subsurface rupture, projected width, and true down-dip width.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
