Some volcanoes are active, while others are dormant.
Last erupted somewhere between 150,000 and 200,000 years ago
This type of volcano is described as dormant. Another level is inactive. This describes a volcano for which there is no record of eruption (unlike dormant), and the volcano's shape and structure is beginning to change due to weathering and erosion.
True. All volcanoes have the potential to erupt again, even if they have been dormant for long periods. Dormant volcanoes can become active again due to changes in geological conditions, such as the movement of magma beneath the surface. However, predicting exactly when a dormant volcano will erupt can be challenging.
Depending on how long they've been inactive - they're called either dormant, or extinct.

It's last eruption was in 1991 so it has been dormant ('asleep') for 20 years.

Mauna Kea has been dormant for approximately 4,500 years. Its last eruption occurred around 2460 BCE, and since then, it has not shown any signs of volcanic activity. Scientists consider it to be a dormant volcano, meaning it is not currently active but could potentially erupt again in the future.
Eyjafjallajökull, a glacier-capped volcano in Iceland, last erupted in 2010. It has been dormant since then, making it currently inactive.
