Caldera volcanoes are the Extreme Volcanoes.
These are the most powerful and catastrophic types of volcanoes because of the unique way in which they form. This type of volcano is shaped more like an inverse volcano. An enormous magma chamber bulges up beneath the ground from the extremely high pressures of the trapped gases within.
Caldera volcanoes are the largest on earth with some calderas measuring from 15 to 100 kilometers wide.
Toba Eruption
74,000 years ago on the island of Sumatra Indonesia, a volcanic eruption so violent occurred that it proved to be apocalyptic for the human race.
The suspension of so much material in the earth's atmosphere resulted in a Volcanic Winter that lasted all year long, every year for several years. The severe drop in global temperatures had catastrophic effects on vegetation and the food chain dependent upon it for survival - including humans.

Well..the most active..I am not sure.
As for the most powerful recorded was Krakatoa
The 1883 eruption ejected more than 25 cubic kilometres of rock, ash, and pumice [2], and generated the loudest sound historically reported: the cataclysmic explosion was distinctly heard as far away as Perth in Australia approx. 1,930 miles (3,110 km), and the island of Rodrigues near Mauritius approx. 3,000 miles (5,000 km). Near Krakatoa, according to official records, 165 villages and towns were destroyed and 132 seriously damaged, at least 36,417 (official toll) people died, and many thousands were injured by the eruption, mostly from the tsunamis which followed the explosion.
The eruption destroyed two thirds of the island of Krakatoa. Eruptions at the volcano since 1927 have built a new island in the same location, called Anak

I know Krakotoa devestated Indonesia when it erupted. It reshaped that area and caused all sorts of problems with tsunamis and the atmosphere. I would be frightened if that became active again.

Do you mean in recorded history or over the last 4.55 billion years?
The volcanoes in the recorded history don't hold a candle to what Earth has seen in the past.
