+When was the last eruption of Biliran volcano?
The last confirmed eruption of Biliran occurred in 1939.
+How often does Biliran volcano erupt?
There are no known historic eruptions, but evidence from geologic records shows that it has had at least 1 eruptions over the past 10,000 years. This number is likely much higher because many past eruptions might not have left evidence recognizeable today and/or the volcano might not have been studied in too much detail. Using the available data, a very conservative estimate is that Biliran volcano erupts every 10,000 years.
+How active is Biliran volcano at present?

+When was the largest eruption of Biliran volcano?
