Colima Volcano in Mexico is considered one of the most active volcanoes in North America, frequently erupting over the past few decades. In contrast, Sangay Volcano in Ecuador is also highly active, with numerous eruptions recorded since the 17th century. While both volcanoes are active, Colima has had more frequent eruptions in recent years, making it appear more active in that timeframe. However, the activity levels can vary over time and are influenced by different geological factors.
It is explosive (it is a stratovolcano). In a worst-case scenario, more than 400,000 people would have to be evacuated from the proximity of the volcano: up to 30 km / 19 mi from the cone.

It is called a active volcano. Inactive volcanoes have not erupted for more than a century.
Mount Etna is an active volcano on Sicily.
An active volcano is a term used to describe a volcano that has erupted within the past 600 years. A volcano that is not active, or has not erupted for 600 years or more is known as dormant.An "active" volcano is any volcano that shows signs of eruption, or that is known to erupt over a period of years or decades.The other type is a "dormant" volcano, which has erupted in the past but not within several decades or centuries.A more specific classification lists volcanoes that are either erupting or likely to erupt as opposed to clasification by varying historical records. Those not on either list are unlikely to erupt in the foreseeable future.

One perpetually active volcano on the Antarctic continent is Mt Erebus, the southern most active volcano on earth.

because there is no evidance of it being active for more than 2000 years

Volcanism forms when two oceanic plates collide, causing the more dense one to subduct under the other. When it goes under, it partially melts and the magma forces upwards to create an active volcano. An active volcano will stay active until cut off from the magma. Also, the more the volcano erupts, the more crust will form, so if a volcano was once under water, an island will eventually form if not cut off from magma.
There was more than one volcano there, active between 42 and 17 million years ago. They are all now extinct and part of the geologic sequence.
A dormant volcano is one that is just sleeping and it is possible to erupt again. An extinct volcano will never erupt again.
Mt Erebus is more or less permanently active, and could be considered the last volcano that erupted in Antarctica.
I don't think it is. White Island is far more of an active volcano than Mt Ruapehu.
