Its USGS Volcano Alert level is at WATCH. We all can do our part to reduce the impact to people and property through education, land-use planning, and response plans. Īs long as people continue to live on the flanks of Hawaii’s active volcanoes, the risks from lava flow hazards are real and potentially tragic. They illustrate what portion of the volcano can send flows in specific directions. Lava inundation zone maps for Mauna Loa are available online and at local libraries.

The Hawaii County Civil Defense website has a whole section devoted to preparedness. What other resources are available to help a community with eruption planning? It is useful to also have a communication plan, so you can be in touch with those you care about. If your family prepares and implements an eruption plan, the details are taken care of and the ohana can meet in a predetermined place. Imagine an eruption starts on Mauna Loa while you are at work. During the day, your tutu and pets stay home but you go to work in North Kona and the kids go to school in Naalehu. Where will the ohana go when an eruption starts? Let’s say you live in South Kona. You may want to include important documents, like your birth certificate, deeds, legal papers, and medications. Nowadays, people pack “go” bags containing essential items in case you have to leave your house under an evacuation order. How can you prepare for a Mauna Loa eruption? The most important thing you can do is to have a personal response plan - especially if you live in or near the red zone. Many flows from the SWRZ have entered the ocean in less than a day (see map for travel times). The west side of Mauna Loa’s Southwest Rift Zone (SWRZ) is in red: flows can reach populated areas in hours because of the steep slopes and vigorous lava production. This region is orange because if a radial vent eruption starts low on the flanks, precious little time may be available for response efforts. Radial vents in this region in the past issued lava from below sea level to the summit of the volcano. This flank has moderate to steep slopes and flows travel at a moderate clip. Mauna Loa’s northwest flank is in orange: flows can reach populated areas in days to weeks. In 1880, an ‘a‘a flow traversed 20 km (16 miles) in 7 days as it advanced toward Kilauea. The southeast flank of the Mauna Loa is in yellow: flows travel at a moderate clip and can reach populated areas in days to weeks. Mauna Loa flows in the past reached Hilo in weeks to months due to the greater distances to populated areas and gentle slopes in the uplands that slow down flow advance. The Hilo area is in blue: lava traversing the northeast portion of the volcano travels at a modest clip. Different sectors around Mauna Loa are colored according to how quickly lava flows can reach populated areas.

The map shown here - modified from the factsheet - indicates the response time people can expect based on the travel times of Mauna Loa eruptions over the past 200 years.

How can you learn what to expect during a Mauna Loa eruption? The USGS Hawaiian Volcano Observatory website has information on lava flows and other volcanic hazards, including a fact sheet specifically about Mauna Loa hazards (). A few minutes spent preparing now could keep you, your ohana, and your community safe. Next, develop a plan with your ohana - what you will do during a natural hazards emergency. What can you do if you live on or near Mauna Loa? A few simple steps can help you prepare: First, learn about the volcanic hazards that could affect your community.
