Answer
Final Answer: The Richter Scale ranking of this earthquake is \(\boxed{4.9}\).
Step 1 ：The Richter Scale is a logarithmic scale used to measure the intensity of earthquakes. The formula to calculate the Richter Scale ranking is: \(R = \log_{10}(I/I0)\) where: \(R\) is the Richter Scale ranking, \(I\) is the intensity of the earthquake, \(I0\) is the intensity of a 0-level earthquake.
Step 2 ：In this case, \(I/I0 = 80000\), so we need to calculate \(\log_{10}(80000)\).
Step 3 ：Using a calculator, we find that \(\log_{10}(80000)\) is approximately 4.9.
Step 4 ：Final Answer: The Richter Scale ranking of this earthquake is \(\boxed{4.9}\).
