I don't know where that person found that answer, or to which erruption it refers, but according to http://www.volcanolive.com/khaybar.html "volcanic activity began at Harrat Volcano 5 million years ago and has continued up to the present. Seven post Neolithic eruptions and eight historical eruptions have been identified at the volcano."
This was not a continuous or near-continuous eruption, but 12 distinct events spread over 5m years.
If continuous eruption's what you're looking for, then according to the Geological Society of America (2005, August 10). India's Smoking Gun: Dino-killing Eruptions. ScienceDaily. The Deccan Traps may have erupted fairly continuously for 30k years.

∙ 11y agoit varies with every volcano, with shield volcanoes the lava is non-viscous and runny, so the eruptions are non violent and frequent. One volcano on Hawaii has been erupting non stop since 1980 and they others can erupt monthly, or every few years. A composite volcano has viscous, thick lava, so pressure has to build over years until it explosivey erupts, this is infrequent and occurs maby every 100 years, some even more than that. These eruptions could take place over a number of days or weeks but may produce ash and gas many months after its eruption.
Calderas are the most explosive and the most infrequent, but easily the most dangerous because the magma is under intense pressure.
Hope this helps :) X

When will volcano Cotopaxi erupt again?
It is impossible to make long-term predictions of when a volcano will next erupt.
What is a volcano that does not erupt called?
It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.
How long does it take for an volcano to erutp?
It varies from volcano to volcano. The super volcano under Yellowstone National Park erupts an average of once every 600,000 years. Others may erupt once, then go extinct. Others may erupt once a century.
What is the name of the volcano is not likely to erupt in the future?
An active volcano is one that is erupting or is likely to erupt.A dormant volcano is one that has not erupted for a long time (but is still possibly active).An extinct volcano is one that is not likely to erupt again.
A volcano that hasn't erupted in a long time and is unlikely to erupt again?
The volcano is said to be extinct if it hasn't erupted for at least 10,000 years.
How long does mount Everest take to erupt?
Mount Everest does not erupt as it is not a volcano.
How long does it take for a regular volcano to erupt?
150 miles the regular volcano is eruption
What happen when a volcano is active?
When a volcano is active it will erupt. These volcanoes might take many years to erupt but will still erupt.
What is a volcano called that never erupt for a long time?
Volcano

How long does a volcano erupt for?
Volcanoes erupt until their lava is gone or until the pressure beneath the volcano is released. There is no way of knowing ahead of time how long that will take. Some volcanoes blow up once and never again, and then there's Kilauea volcano in Hawaii, which has been erupting since 1983.
A volcano that hasn't erupted in a long time and is unlikely to erupt again?
The volcano is said to be extinct if it hasn't erupted for at least 10,000 years.
When does an active volcano erupt?
They can erupt anytime, when magma rises from the mantle and spews out of the volcano.
