* Mount Tambora, Indonesia, 1815, 10-15 April, 92000 deaths. The explosion, of Volcanic Explosivity Index 6-7, released 4 times the energy of the 1883 eruption of Krakatoa and it ejected an estimated 100 cubickm of pyroclastic trachyandesite, weighing approximately 2-3 × 10^14 kg.
* Krakatau, Indonesia, 1883, 20 May - 27August, 36417 deaths. The eruption ejected more than 25 cubickilometres of rock, ash, and pumice, and generated the loudest sound ever historically reported — the cataclysmic explosion was distinctly heard as far away as Perth in Australia (approx. 3100 km), and the island of Rodrigues near Mauritius (approx. 4800 km). Atmospheric shock waves reverberated around the world seven times and were felt for five days. According to official records, 165 villages and towns were destroyed and 132 seriously damaged, at least 36,417 people died, and many thousands were injured by the eruption, mostly in the tsunamis which followed the explosion.
* Pelee, Martinique, 1902, April 23 - 1905, July 4, 30000 deaths. The main eruption, on May 8, 1902, destroyed the town of Saint-Pierre, about 4 miles south of the peak.
* Nevado del Ruiz, Colombia, 1985, November 13, 25000 deaths. Pyroclastic flows melted ice and snow at the summit. This melt formed lahars that rushed down several river valleys. The lahars were up to 50 meters thick and travelled more than 100 kilometres. Many houses and towns were devastated by the lahars. The town of Armero was completely covered by debris. The eruption caused an estimated 25,000 deaths, 5,000 injuries, and destroyed more than 5,000 homes. This was the second-deadliest volcanic disaster in the 20th century (the 1902 eruption of Mount Pelée was the worst).
* Pinatubo, Philippines, 1991, March 21 - June 15, only 300 deaths, but it was the the largest and most violent eruption of the 20th century, successfull evacuation saved thousands of lives.

Tambora 1811-1812 was many times greater than Krakatoa in 1883
Toba, in Sumatra Indonesia blew 60,000 years ago. The caldera is a lake about 22 miles long and 2 or 3 miles wide. (look it up for the exact dimensions.)
There is some molecular biological/biochemical evidence that it came close to wiping out the human species. They calculate that about only 1,000 individuals survived world-wide. (measurements were made of the lack of genetic diversity of many human proteins as compared to those of some other primates.).

Tambora has been the deadliest volcano have killed 92,000 people in 1815. The Tambora eruption cooled the climate in the northern hemisphere and many people starved as a result.

OK, so what are you asking? The names of the volcanoes? The Indonesian volcano was Krakatoa. The one in the philippines is Pinatubo.
