Not usually. Mafic magma usually has a low gas content than felsic or intermediate magma, so eruptions are often effusive. Cinder cones primarily erupt mafic lava with a low level of explosivity. Explosive eruptions can also occur if the magma comes in contact with groundwater.

Why are eruptions of mafic magma rather quiet?
The explosive force of violent eruptions is driven by gas trapped in the magma under pressure. Mafic magma often has a relatively low gas content and so usually erupts in a non-explosive or mildly explosive.
Magma that is relatively thin dark colored and low in silica?
A low silica magma is called a "mafic" magma.
This type of magma has low silica content?
There are three types of magma that contains silica. Basaltic Magma has 50 percent silica, Andesitic Magma has 60 percent silica, and Granitic Magma has 70 percent silica.
What type of magma does surtsey have?
mafic magma
How the composition of magma determines an eruption's characteristics?
Silica(te) rich magma is usually an explosive eruption. The explosiveness of an eruption depends on - a) Gases trapped within the magma at eruption b) The Silica content c) The fragility of the crater walls and/or the volcanic plug.
Does mafic magma explode?
Mafic magma can be involced in both explosive and non-explosive eruptions.

What do quiet lava eruptions generally result from?
Volcanic eruptions are always caused by magma. This applies if the eruption is quiet or explosive, or whether the magma is felsic or mafic.

The types of magma?
Felsic, intermediate, mafic and ultra mafic are the four broad types of magma.
What type of magma does surtsey have?
mafic magma

Mafic mineral low or high density?
Mafic magma and rock are higher in density that felsic magma and rock.
What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
What are two types of magma?
The three types of magma are basalt, andesite, and rhyolite. Basalt is flowing and is usually around 1,200 degrees Celsius. Andesite is flowing and explosive and is usually between 800 to 1,000 degrees C. Rhyloite is very explosive and is usually at 750 to 850 degrees Celsius.
