Hawaii is far removed from geological fault lines (which makes the Hawaiian volcanoes also something special), but the hot spot below the Hawaiian islands and the volcanic activity caused by it causes enough stress in the earth’s crust to make Hawaii a very active seismic region.
Hawaii is well known for its volcanic hazard, but the islands are also susceptible to major earthquakes such as a magnitude 7.9 quake in 1868 that killed 77 people. Evidence of prehistoric quakes is hard to come by in Hawaii , making it especially difficult to guess when the next big one will strike.

Active shield or postshield volcanism (with dikes injected along rift zones) and high rainfall appear to be two components needed to trigger the deep-seated giant Hawaiian landslides .
Though the ring encircles the Pacific, Hawaii is not technically part of it. That said, the volcanic or tectonic activity along the ring remains a risk, as described in Kathryn Schulz’s Pulitzer-winning piece, “The Really Big One”: The Ring of Fire , it turns out, is really a ring of subduction zones.
The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line , is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.

Local tsunamis originate off the coast of Hawaii Island and first wave arrival could be under 30 minutes. Distant tsunamis originate off the coast of Japan, Aleutian Islands, Chile, etc. These tsunamis can take anywhere from 5 to 14 hours for first wave arrival.
Thousands of earthquakes occur every year in the State of Hawaii . They are caused by eruptive processes within the active volcanoes or by deep structural adjustments due to the weight of the islands on Earth’s underlying crust. Some are strong enough to be felt on one or more of the islands.
Scientists say that the tsunami that hit Japan in 2011 was a thousand-year event. A monster wave might strike Hawaii about as often. The most destructive tsunami in Hawaii’s recent history took place in 1946.
Overall, Honolulu is an extremely safe city to visit. While the city does have some problems with petty theft and DUIs, the police department has successfully worked to reduce the violent crime rate.
The Island of Hawai’i, with four active volcanoes , is liveliest. Between 1912 and 2012, there were nearly 50 Kīlauea eruptions, 12 Mauna Loa eruptions, and one Hualālai intrusion of magma. Mauna Kea most recently erupted only about 4,000 years ago.
VOLCANOES NATIONAL PARK, HAWAII (KHNL)- A major chunk of Hawaii Island is set to fall into the ocean any day now. It’s newly formed lava land, and it grows more unstable by the day. When lava meets ocean , it cools and forms glass like rubble underwater.
SAN FRANCISCO — It’s almost unimaginable: a tsunami more than 1,000 feet (300 meters) high bearing down on the island of Hawaii . But scientists have new evidence of these monster waves , called megatsunamis, doing just that.
On January 10, 2005 , a major landslide occurred in the town of La Conchita , California. The landslide killed 10 people, and destroyed or damaged dozens of houses. The landslide occurred on part of a previous landslide that occurred in 1995.
