What is potentially active?
Potentiallly active refers to the grouping of two categories within the inactive population: persons available for the labour market but not seeking work; persons seeking work but not immediately available.
What is the difference between a potentially active volcanoes?
Active volcanoes have a recent history of eruptions; they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.

What are the potentially active volcanoes in Luzon?

Examples of dormant volcanoes are Mount Kilimanjaro, Tanzania, Africa and Mount Fuji in Japan.
What is an active volcano called?
An erupting volcano is an active volcano that is having an eruption… A dormant volcano is an active volcano that is not erupting, but supposed to erupt again.

Why does Philippines have many active volcanoes?
The Philippines sits on a unique tectonic setting ideal to volcanism and earthquake activity. It is situated at the boundaries of two tectonic plates – the Philippine Sea Plate and the Eurasian plate – both of which subduct or dive beneath the archipelago along the deep trenches along its east and west seaboard.

What determines if a volcano is active?
The Smithsonian Global Volcanism Program defines a volcano as active only if it has erupted in the last 10,000 years. Another means for determining if a volcano is active comes from the International Association of Volcanology , who use historical time as a reference (i.e. recorded history).
What causes a volcano to be active?
Volcanoes become active when new or remobilized magma reaches a shallow enough depth beneath the volcano to start erupting to the surface. Magma comes up from deep in the Earth, usually from the mantle, and it can pause at very deep levels of the crust for long periods.
What is the difference between active and inactive volcano?
An active volcano is a volcano that has had at least one eruption during the past 10,000 years while an inactive volcano is one that could erupt but has not erupted for more than 10,000 years.
What are the characteristics of an active volcano?
A volcano is active if it’s currently erupting or showing signs of unrest. The Smithsonian Global Volcanism Program defines an active volcano as having erupted within the last 10,000 years. A volcano finally goes extinct when there’s no lava supply in the magma chamber beneath the volcano.
