Hi! Here are those geology questions, let me know if you have any questions!It was great working with you!
B, Low Viscosity, Low Gas
A, High Viscosity, Low Gas
C, High Viscosity, Low Gas
D, High Viscosity, High Gas
When a volcano erupts there are multiple factors that go into the type of eruption
and its severity. The type of eruption that will be most hazardous is one with high
volatility and high viscosity. Generally high volatility is paired with low viscosity but
in this scenario as the gas is released during eruption the viscosity is increased and
the eruption is explosive.
7. The peak discharge for the 100-year flood is about 70,000 cfs. The data values are
for an interval of 25 years. 2001 would be the 26th year. Using the log-log plot most
of the recurrence intervals are in a 10 year period but of the 52 data points only 1
falls between 20-30 years. The probability in 2001 would be 1/52 or 1.92%.
8. The recurrence times for the data from 1975-2000 is given by the equation
Recurrence time = n+1/rank , n=# years on record. The recurrence time is 25+1/1
= 26 years. Looking at the chart there is only 1 data point around this interval so the
probability of it occurring is 1/52 or 1.92% each year.
9. After the Army Corp of Engineers raised the levees the overflow of the river was
changed. The levees are built to prevent overflow so the new data would show that
the river had lower overflow levels compared to the pre 1975 data. This would
suggest water levels were declining when they are not.
10. The recurrence time for such a flood in 2006 using the data from 1975 to 2000 is
calculated using the equation: Recurrence time = n+1/rank ...
