The eruption, which is still going on, is a VEI-0.
The 1980 eruption of Mount St Helens was a VEI 5.
It has blowen in the past at VEI 5-6, so can expect the same in the furure

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.

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)
Geologist believe Mt. Fuji was formed approximatey 600,000 years ago during the Pleistocene era. The last recorded eruption was the Hōei eruption, which started on Decemeber16, 1707 and ended about January 1, 1708.
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
