The islands of Hawaii have been formed from lava flowing up from the seafloor in the central Pacific. This "hotspot" has stayed in the same place as the ocean floor slowly moved NW due to crustal spreading. As each island moved away from the hotspot, it lost the supply of new lava from below. Only the volcanoes of the "big island" (Hawaii) and a smaller underwater seamount (Loihi) are currently spewing new lava. Eventually the big island's volcanoes will also stop as it moves off the hotspot after a few thousand years.
What else can I help you with?
Does every Hawaiian island have a volcano?
Most of the Hawaiian islands were formed by volcanic activity, but not all islands currently have active volcanoes. The Big Island of Hawaii is home to active volcanoes, while some of the other islands, such as Kauai and Oahu, have dormant or extinct volcanoes.
What continent does not have any volcanic activities?
Australia is the only continent without any active volcanoes. However, there is one active volcano on Australian territory, that being Big Ben on McDonald Island in the sub-Antarctic territory of Heard & McDonald Island.
How many years does it take for a volcanic island rise?
It varies widely depending on the type of volcano and the depth of the ocean in the area. The volcanoes that formed the Hawaiian islands took hundreds of thousands of years to form. They are shield volcanoes that merged from the deep ocean floor. Anak Krakatau, a statovolcano, emerged in shallower waters in 1927 after the destruction of its predecessor, Krakatoa, in 1883. This is a time span of only 44 years.
Can something be both a mountain and a volcano?
A mountain could be a volcano and a volcano can be a mountain. A volcanic mountain is only one type of mountain. Mt. St. Helens in the United States is a volcanic mountain. The Hawaiian Islands are a string of volcanic mountains. And the world's largest mountain range is the mid-ocean ridge, created by diverging tectonic plates and volcanism.

How many volcanic islands does Hawaii have?
All of the Hawaiian Islands are volcanic, but only Hawaii, the Big Island, has active volcanoes at this time.
What Hawaiian island has active volcanoes?
There are hundreds of active volcanoes in the world, a few of which are in Hawaii. The most active Hawaiian volcano, Kilauea, is one of the most active in the world.

How many people in Hawaii live next to a volcano?
This is a somewhat "trick" question. Since all the Hawaiian islands were formed through volcanic activity, theoretically all Hawaiian residents live next to (or ON) a volcano. But if you mean active, the only active volcanos are on the Big Island (Hawaii itself) and the island's population was around 175,000 in 2008.
How can seamount become an island?
An island can become a seamount only if there is native and active volcanic activity that is able to raise the landmass sufficiently above sealevel.

No: there's only volcanic activity
The geysers built in 1960 in northern California remains the worlds premier what?
Geysers are not built, but are the result of volcanic activity. The only volcanic activity in Northern California is Mt. Shasta. Mammoth Lakes is also a very active area.
Who made St Maarten?
Your question is not clearly defined, so we may only guess at an answer. If you mean Sint Martaan, half of the Caribbean Island of St Martin, it was made or formed by volcanic activity
