Order of earthquakes
In this exercise you will use the ACF and PACF plots to decide on the most appropriate order to forecast the earthquakes time series.
| AR(p) | MA(q) | ARMA(p,q) | |
|---|---|---|---|
| ACF | Tails off | Cuts off after lag q | Tails off |
| PACF | Cuts off after lag p | Tails off | Tails off |
The earthquakes time series earthquake, the plot_acf(), and plot_pacf() functions, and the ARIMA model class are available in your environment.

# Create figure
fig, (ax1, ax2) = plt.subplots(2,1, figsize=(12,8))
# Plot ACF and PACF
____(____, ____=____, ____=____, ax=ax1)
