Why are there volcanoes? Why do they erupt? | Volcano.

Kilauea is buttressed on its north-west side by the enormous mass of Mauna Loa volcano , but its south-east slopes face the ocean and are unsupported. The magma from beneath the volcano usually erupts from the summit of the volcano, and there was a spectacular lava lake there in March. However two rift zones (areas where the volcano is splitting apart), extending east and south-west from the summit, can make it possible for lava to erupts from Kilauea’s flanks too.
There are active volcanoes in every part of the world. There are about 1,500 active volcanoes, many in the region of the Pacific Ocean. 
There are two dormant volcanoes within driving distance of Vancouver that have the potential for eruption, those are Mount Garibaldi in Squamish and Mount Baker in Washington, and there are 14 dormant and extinct volcanoes within 100km of downtown Vancouver. Here they are:
The Volcanoes of the World database provides a catalog of Holocene and Pleistocene volcanoes, and eruptions from the past 10,000 years.
“The upwelling we detected is like a hot air balloon, and we infer that something is rising up through the deeper part of our planet under New England,” lead author Vadim Levin of Rutgers’ Department of Earth and Planetary Sciences says . “It is not Yellowstone (National Park)-like, but it’s a distant relative in the sense that something relatively small – no more than a couple hundred miles across – is happening.”

Wow, there is smoke coming out of the crater ! Stop the volcano from exploding by guiding the lava safely down. - The lava maze
Educational web site focused on the long-lived eruption of the Soufri?re Hills volcano , Montserrat, Lesser Antilles, and the hazards it poses to residents.
The Volcano Theater Company was founded in 1974. The company conducts a full season each year, performing in both the 1856 Cobblestone Theater and in the larger outdoor Volcano Amphitheater.
The current activity is based along the east rift zone. According to the US Geological Survey , 23 separate new fractures there became volcanic fissures from which lava was erupted. By the end of May, “fissure 8” (the eighth new fissure to have announced itself) had become dominant – with activity at the others ceasing or subsiding. This was the source of the lava that by June 4 was flowing into the sea several miles away near the Vacationland resort, where it completely filled what had previously been Kapoho Bay .
