What are Volcanoes?
... Often people think of a river of red-hot lava when they think of a volcanic eruption. Lava flow is a river of hot lava. Lava flows are common in nonexplosive eruptions where the lava flows continually. Sometimes they will spray, they are not explosive. ...

Stratovolcano and Shield Volcano Morphology

Mount Pleasant Caldera
The Mount Pleasant Caldera is a large eroded Late Devonian volcanic caldera complex, located in the northern Appalachian Mountains of southwestern New Brunswick, Canada. It is one of few noticeable pre-Cenozoic calderas, and its formation is associated to a period of crustal thinning that followed the Acadian orogeny in the northern Appalachian Mountains.It sits relatively near to the coastline.
