Volcanoes - Types and structure
... These volcanoes are created at constructive margins. This is where two plates are moving apart from each other and magma moves to the surface through the gap. The emerging lava is more fluid and therefore the shape of the volcano is low and wide. This is why it is called a ‘shield’ volcano. ...

Lastarria
Lastarria, also known as Azufre, is a stratovolcano along the border of Argentina (border of the Catamarca and Salta provinces) and Chile (Antofagasta region). The volcano is part of the Lazufre volcanic system and is noted for the presence of molten sulfur lava flows as well as a debris avalanche. There is no recorded activity in historical times, but ground inflation has been observed.
