The Mount Tambora (1815 eruption) was a 7 on the Volcanic Explosivity Index, ( VEI), responsible for 92,000 deaths, is the largest and deadliest volcanic eruption in recorded history.
It was so large it caused the "Year Without a Summer" in 1816,  see here and here.
In 1833 the  Krakatoa eruption killed 36,417, and scored a 6 on the Volcanic Explosivity Index, ( VEI) and was heard 3,000 miles (4,800 km) away.
It caused a 5 year volcanic winter.
The island had three volcanoes.
Perboewatan (410 ft) and Danan (1,480 ft) was destroyed during the eruption while Rakata (2,667 ft) was only half destroyed but it still remains above sea level.
In 1928, a new volcano called Anak Krakatoa (1,063 ft) grew above sea level, forming a new island by Rakata's island.
The largest eruption in the 20th century was the Novarupta volcano in 1912
