This is Waianae a Volcano in Hawaii!
Here is a typical shield volcano diagram it is very
simple and easy to understand.
This is a shield volcano 
which is located in 
California named Medicine Lake
Shield volcanoes
By:Aschlynn
A shield volcano is a volcano with sloping sides. Shield volcanoes mainly form from lava flows that can go long distances across slight slopes, resulting in their relatively flat, broad profile. Some of the largest volcanoes on Earth are shield volcanoes.(The largest known shield volcano is Olympus Mons on Mars, with a height of 25 km and width of 600 km)
They are large volcanic forms with broad summit areas and low-sloping sides which makes the shield shape, because the extruded products are mainly thick basaltic lava flows. A good example of a shield volcano is the Island of Hawaii aka the "Big Island". The "Big Island" is formed of five volcanoes that are close together. 
This is the eruption
of Kilauea in Hawaii.
Heres some facts about Shield Volcanoes.
They are low in silica witch is what makes them red hot. 
They're non stop flowing.
They don't erupt they just distruibte lava that oozes out.
Shield volcanoes are formed by eruptions of runny basalt lava which flows swiftly and does not build up in a cone shape.
the lava can flow for miles


Above is lava from the volcano oozing out.

Types Of Lava Fountains

Arching fountain:

Instead of shooting lava vertically from a vent, an arching lava fountain sends lava upward and outward. Arching fountains form when the shape or geometry of an erupting vent forces the lava outward in a continuous stream of airborne lava. 

Dome fountain:

Dome fountains are hemispherically shaped lava fountains that form when the upward pressure of magma from the conduit below is in approximate equilibrium with the mass of ponded lava through which it passes. Dome fountains may reach as high as several tens of meters, and they typically occur in relatively gas-poor lavas. 

Lava fountain:

A jet of lava sprayed into the air by the rapid formation and expansion of gas bubbles in the molten rock is called a lava fountain. Lava fountains typically range from about 10 to 100 m in height, but occasionally reach more than 500 m. Lava fountains erupt from isolated vents, along fissures  within active lava lakes , and from a lava tube when water gains access to the tube in a confined space
