No. "Category 5" is a rating on a system, used for hurricanes. Mount Pinatubo is a volcano. Volcanoes do not have a rating system but eruptions do: Volcanic Explosivity Index, which ranges from VEI 0 to VEI 8. On this scale the 1991 eruption of Mount Pinatubo was a VEI 6.
The 79 eruption of Mount Vesuvius was estimated to have been a VEI 5.
The famous eruption of Mount st Helens in 1980 was a VEI-5.
Volcanic eruptions don't go by the Richter Scale.. perhaps you are thinking of the VEI (Volcanic Explosivity Index) Scale? If so, the VEI of Mt. Lamington was a level 5.
Volcanic Explosivity INdex (VEI)
Mauna Kea does that have a recorded VEI, as it has not erupted for over 4500 years, but is said to be around VEI-2
Battle of Lang Vei happened in 1968.
