That would be the Indonesian volcano Krakatoa. The main eruption on the 27th was heard more than 2,000 miles away in northern Australia, however the eruption actually began in May 1883. Two thirds of the 5 mile long island were decimated.
The volcano is said to be extinct if it hasn't erupted for at least 10,000 years.
It is said to be dormant.
Dormant volcano
That volcano is likely to erupt again. Every volcano is different ,research on the volcano and when was the last time it erupted and then add 500 to 1000 years.
The opposite of an active volcano is an extinct volcano, which is a volcano that has not erupted in a long time and is not expected to erupt again.
The Krakatoa volcano erupted in 1883 in the Sunda Strait, located between the islands of Java and Sumatra in Indonesia. The eruption caused one of the most powerful volcanic explosions in recorded history, resulting in devastating tsunamis and a significant loss of life.
No. Weathering will gradually destroy a volcano that has nor erupted for a long time.
