Hi, 6mpettha! To answer your question litterally, it would be a shield volcano such as what you find in Hawaii. They don’t really “explode” but rather ooze lava.
But really, what determines if a volcano is eruptive or not is the colposition of its magma. If it is low in silica content, it will be a “quiet” eruption (basaltic composition — low silica hence quiet) and if it is high in silica content it will be a more violent eruption (grantic — high silica, hence explosive). Also, the amount of water vapor and other gases that are trapped in the magma, the more, the more explosive.
I agree with Jesse. The lower the silica content, viscosity, and gases, the lower the chances that there will be an explosion. Usually volcanoes in the mid-oceanic rifts and shield volcanoes produce runny lava. The eruption of Mauna Loa in Hawaii produces lava that can travel for kilometers and tourists can watch as the lava moves. Because there are almost no explosions, the volcano is not as dangerous as others. Of course there are other dangers such as toxic gases that could come out of the volcano vent and affect people.

Hi 6mpettha,
I agree with the other scientists.
The following is a short documentary on the shield volcanoes: http://www.youtube.com/watch?v=byJp5o49IF4
Hope it helps! 🙂

This will be on the list of things I learned today 😉
