Zone 9 - Kohala Volcano, which last erupted over 60,000 years ago. Lava Flow Hazard map of Haleakala. The Maui Hazard Zone numbers are a different scale from the island of Hawaiʻi's map. The lava flow hazard zones on Maui use a different scale. They can be compared to Hawai'i Island's lava zones. [4] [5]
Mackenzie, Muschalik & Broesche (2021) provided comments on the 2018 report in three separately authored sections. [4] Broesche believes that Yellowstone should be ranked higher due to the size of the volcano and the popularity of Yellowstone National Park, and Muschalik considers Mount Rainier to be just as dangerous as Kilauea due to its proximity to large population centers in Washington.
A volcanic hazard is the probability a volcanic eruption or related geophysical event will occur in a given geographic area and within a specified window of time. The risk that can be associated with a volcanic hazard depends on the proximity and vulnerability of an asset or a population of people near to where a volcanic event might occur.
On the island of Hawaiʻi, lava-flow hazards are rated on a scale of one through nine with one being the zone of highest hazard and nine being the zone of lowest hazard. For example, the summits and rift zones of Kilauea and Mauna Loa volcanoes are rated Hazard Zone 1. [10]
Hazard map. Mount Rainier is a stratovolcano in the Cascade Volcanic Arc that consists of lava flows, debris flows, and pyroclastic ejecta and flows. Its early volcanic deposits are estimated at more than 840,000 years old and are part of the Lily Formation (about 2.9 million to 840,000 years ago).
Local emergency services shared a graphic on Facebook showing what parts of the 133 square-mile island were at risk of damage from the eruption.
Take Iceland, for example. With the region facing numerous eruptions from a volcano since the end of 2023, dramatic photos and video show lava shooting from a long fissure that opened up.
Example of a hazard map. A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards, such as earthquakes, volcanoes, landslides, flooding and tsunamis. Hazard maps help prevent serious damage and deaths. [1]
