Kilauea is considered one of the worlds most frequently active volcanoes. If you just look at the number of Kilauea eruptions recorded since Europeans arrived, there have been 62 eruptions in 245 years, which comes out to 1 eruption every 3.95 years. However, this completely ignores the fact that some of the eruptions lasted a long time. For example, the current eruption started in January of 1983 and has been continuous ever since! Likewise, there was an active lava lake in the summit caldera from at least 1823 until 1924, while at the same time eruptions would take place elsewhere on the flanks of the volcano.

Mauna Loa is an active volcano and is due for an eruption. Mauna Loa has erupted 15 times since 1900. These eruptions have lasted from a few hours to 145 days. Since 1950 Mauna Loa has erupted only twice, in 1975 and 1984. The 1975 eruption lasted 1 day. The 1984 eruption lasted 3 weeks. Nearly all the eruptions begin at the summit. About half of these migrate down into a rift zone.

Haleakala began growing on the ocean floor roughly 1-2 million years ago. It erupted most recently in 1790 at La Perouse Bay.

Hualalai is an active volcano. The resort town of Kailua is on the southwest flank of the volcano. Hualalai last erupted in 1801 and sent lava from a vent on its northeast rift down to the ocean. Swarms of earthquakes in 1929 were probably the result of magma movement within the volcano but there was not an eruption. Hualalai is monitored by geologists of the U.S. Geological Surveys Hawaiian Volcano Observatory. In the last 24 years there have been no swarms of microearthquakes nor any harmonic tremor. Since the early 1980s the geologists have been surveying the volcano. Hualalai is not expanding at the present time nor has expanded since the geologists began making their measurements. If anything changes Im sure well hear about it.

Loihi means long one, a reference to its elongate shape. For a 3-d image, check out the Hawaii Undersea Geological Observatory (HUGO) home. Right now, the summit of Loihi is about 970 meters below sea level. It is growing on the lower flanks of its two neighbors, Kilauea and Mauna Loa, with its base at a depth of about 4000 meters below sea level, so you can say that Loihi itself is about 3000 m high. We dont really know when it will reach the surface or even if it will. There is an underwater volcano off the NW coast of the big island of Hawaii named Mahukona, and there is debate about whether it ever grew above sea level, or died out prior to doing so. The most often-heard time required for Loihi to reach sea level is about 10,000 years, but that is really only a guess. It might be 30,000 years for all we know. It is far enough away from the coastline of Hawaii that I imagine that at first it will be a separate island when it breaks the surface. As it grows (and especially if Kilauea and Mauna Loa are still erupting) it will soon be joined to the island.

002 wrote I think people who live out there are insane tbh. Not trying to offend anyone, buy you live on an island (or chain of islands) that can get wiped out by a tsunami, and you are living on a volcano. Other than that, prices on everything are WAY too high for my liking lol.

Lol bro the Big Island has the tallest mountain in the world from sea level, Mauna Kea. I think we're fine from tsunamis haha.

But seriously the islands aren't that small that it could easily get wiped out from a tsunami. Maybe from one in like the Hollywood movies yea but the likelihood of that happening in our lifetime is slim.

And the only active volcano in Hawaii is on the Big Island, but by active it doesn't mean its spurring lava everywhere across the island 24/7.

That is not the tallest mountain in the world from sea level, Mt. Everest is. Mauna Kea is the tallest when measuring from the base (which is under water) to its summit. Mt. Everest is almost 2x taller than Mauna Kea from sea level to summit.

As far as tsunamis, no I doubt they'd wipe out 100% of the island lol, but you get something like what happened in Japan a few years back and Hawaii is going to be in a world of hurt. Any place would be, but Hawaii is so hard and expensive to get to. It looks like Hawaii has a lot of earthquakes too.

Also, there are 5 active volcanos currently in Hawaii. An active volcano is a volcano that has had at least one eruption during the past 10,000 years.
