Yes it is true
Yes, Mauna Loa is an active shield volcano on the Big Island of Hawaii and is one of the most active volcanoes in the world. It has erupted 33 times since its first well-documented historical eruption in 1843, with its last eruption occurring in 1984. Due to its active nature and frequent historical eruptions, it is expected to erupt again in the future.
Mount Mayon in the Philippines first erupted in recorded history in 1616. It is one of the most active volcanoes in the Philippines, with numerous eruptions occurring since then.
mount etna did not erupt in 1669.
The first eruption was on the 18th of May, 1980.
The first eruption of San Miguel(also known as Chaparrastique), El Salvador was in 1510.
The first documented eruption of Mount Aso was in 553. The last time it erupted (as of 2014) was in 1993.
It depends on the volcano to determine how long it takes to erupt. Mauna Loa in Hawaii erupts almost all of the time and for a long time. While Mt. Saint Helens in Washington hasn't had a huge eruption in almost 30 years. From the time when a volcano starts having activity for the first time in years, it may take seconds, weeks, or even months before you actually have an eruption.
1820. 1820 is the last recoded erruption, not the first. Rock layers of the volcano are 500,000 years old, therefore one may conclude that the first eruption would have been approximately 500,000 years ago. Mt Rainier is predicted to erupt again, has hot springs and local authorties have emegency plans prepared in the event of a new eruption.
I believe that that the first recorded eruption of Oshima Volcano was in 7 AD.
sometimes the first eruption causes new side vents to open up. Because of this, the second eruption could be more powerful and deadly-pliniann eruption
The first eruption scientists think, was in 1808. Then, there was another in 1821 and again one in 1843. The eruption of 1963 is the biggest and most destructive recorded eruption for Mount Agung.
it is highly unlikely u will see pigs fly first
