Selected Tools for Awareness and Preparation

by Rachel LentzOften, coping with natural hazard preparation involves being aware of key information pertinent to that event. But sometimes that information may be hard to find or understand. Here are four resources that should prove useful to your own personal awareness and preparation as well as the preparation of your community. NOAA NWS National and Central Pacific Hurricane Center During the Central North Pacific hurricane season from June 1st to November 30th, the National Weather Service’s National and Central Pacific Hurricane Centers website presents a variety of resources for the Central and Eastern Pacific regions, as well as the

Facing the Storm

by Mara Johnson-GrohSince the day it was born out of the Pacific, 65 million years ago, Hawaiʻi has been sculpted by storms, volcanic eruptions, hurricanes, earthquakes, landslides, and tsunamis. In the 21st century Hawai‘i is facing an increasing frequency of disasters as climate change exacerbates weather patterns and raises the sea level. Over the past few decades, the sea level has already risen by several inches and even if carbon emissions remain the same, conservative estimates suggest a further 3.2 feet of rise by later this century. A 2017 report, the Hawaiʻi Sea Level Rise Vulnerability and Adaptation Report, found

“Like the Whole Ocean Was Coming at You”

by Josh McDanielThe science of tsunamis has expanded in leaps in recent decades. From advances in detection and alert systems to coastal inundation modeling and mapping, we now know more about the seismic forces that trigger tsunamis and can forecast how tsunamis will flood distant coastlines hours before the waves arrive. However, successful preparation for a tsunami still occurs at the community level, preparing infrastructure for the unique destructive forces that occur and educating people on how to react and get to safety. While there have been several tragic tsunamis in the recent past across the globe, we are learning

Going Beyond Code

To support Hawai'i's 100% renewable energy goal by 2045, Hawai'i Sea Grant faculty, their colleagues, and seven student researchers just published a paper to show how house design and construction practices can be modified to meet the newly adopted, more restrictive energy codes and renewable energy goals. The research was conducted through the University of Hawaii, School of Architecture – archawaii and  University of Hawai'i Sea Grant College Program The paper is accessible for free online: https://www.mdpi.com/2075-5309/10/7/120

Community Means Resilience

by Natasha VizcarraDays before Hurricane Iniki slammed into the island of Kauaʻi in 1992, condominium and apartment managers went door-to-door to make sure their residents were preparing for the storm. Hours before the storm struck, motorists honked their horns in places where warning sirens could not be heard. Iniki soon churned over Hawaiʻi with winds of up to 145 miles per hour and gusts of up to 225. By the time it dissipated, six people were dead, thousands of homes were in shambles, and most of Kauaʻi was without power. Iniki was the costliest hurricane to strike Hawaiʻi, causing $3.1

Eruption

by Sara LaJeunesseOn April 30, 2018, the Puʻu ʻŌʻō cone of the Kīlauea volcano collapsed, triggering an eruption that would last for four months. Over that time, as lava drained for miles underground, long fissures ripped through the Earth’s surface, spewing lava at up to 26,000 gallons per second. Earthquakes—up to 6.9 in magnitude—rocked the ground, and dangerous levels of sulfur dioxide gas filled the air. By the end of the eruption, 716 homes were destroyed, and some 3,000 residents were displaced. The lava caused an estimated $236.5 million in damages to public infrastructure, $27.9 million in farm losses, and

The Storm, the Flood, and the Future

by Jake BuehlerThe afternoon before the flooding, you would have been hard-pressed to find any reason to suspect it was coming. It was an idyllic, mid-April day in Hanalei, Kauaʻi, after all: 79 degrees, a mix of sun and clouds, and with a steady, beach-cooling wind out of the northeast. Over the next 48 hours, though, a truly staggering quantity of water would pummel the northern reaches of the island. The subsequent flooding—the result of meteorological quirks converging with maximal potency—precipitated destruction. Yet, the disaster and recovery has precipitated something else in turn: a response from community that lends a

How Food Secure Are We if Natural Disaster Strikes?

by Lurline Wailana McGregorOn June first every year, the Central Pacific hurricane season officially begins. In anticipation of the heightened threat that it brings to the Hawaiian Islands, government preparedness offices take the opportunity to remind all residents to have an emergency kit that includes at least fourteen days of food, water, medication, and other essential supplies. In the past, the likelihood of a hurricane making a direct hit on the Hawaiian Islands was rare, but climate change and the northward shift of hurricanes towards the islands have increased the chance of landfall. Other natural disasters can befall our islands,

The Three ‘Io Brothers and the Big Bad Hurricane

by Keri Kodama There lived three ‘Io brothers on the island of Hawai‘i. They had just left their nests and were on their way to make their living in the world. Each had bought his own house on the mountainside. One day, on their way home, they came to a big cluster of animals gathered around a single panicked rat. “A monster is coming! A monster is coming!” the rat cried, waving his arms around madly. The ‘Io brothers looked at each other. The third brother, who was the smartest and most responsible of the three said, “What are you

The Joy of Limu

by Miwa TamanahaLimu is food, first and foremost, for fish, forming part of the foundation of a complex trophic web that spans from plankton to people. Limu is also food for people, probably most commonly brought to mind as an essential ingredient in our lunchtime poke bowls. Limu has extensive uses in all manner of foods, both Hawaiian and the many other ethnic types represented in our communities, and at events from baby parties to New Year celebrations. Pickled, salted, dried, raw, chopped, fried, boiled, no matter the form, limu for eating is a gift shared among friends and family

Limu Traditions

by Lurline Wailana McGregor“When I was growing up, if you went to a lūʻau, you would know who prepared the food and what area it came from by just knowing the taste of the limu and the kinds of limu that were utilized. Basically, you could tell where the families came from by the raw stuff they made,” says Malia Akutagawa, who was raised on the east end of Molokaʻi. Now 48 years old and an assistant professor of law and Hawaiian Studies with both the University of Hawaiʻi at Mānoa’s William S. Richardson School of Law and the Kamakakūokalani
Removing Invasive Algae to Restore Native Ecosystems

Removing Invasive Algae to Restore Native Ecosystems

by Paula MoehlenkampWhile the diversity and beauty of plants on land are easily seen by us, we may often overlook their aquatic counterparts hidden beneath the sea. Algae, photosynthetic plants ranging from microscopic phytoplankton to larger seaweeds, live in fresh and seawater and fulfill a variety of important functions, including the production of oxygen and the provision of habitat and food. Although limu, various species of seaweed native to Hawai‘i, are an integral part of the environment, the rapid spread of invasive algae over recent decades has raised concern for the future health of limu and their ecosystems. Originally, multiple

Growing a Network of Limu Practitioners

by Josh McDanielUncle Wally Ito is passionate about limu, or seaweed. He says limu has always been an integral part of Hawaiian culture, with uses in food, medicine, and religious ceremonies. In a traditional Hawaiian diet, limu was the third component of a nutritionally balanced diet along with fish and poi, providing an important source of minerals and vitamins. Limu, such as wawae‘iole (Codium edule), manauea (Gracilaria coronopifolia), ele‘ele (Ulva prolifera), kohu (Asparagopsis taxiformis), and līpoa (Dictyopteris plagiogramma), are still a common ingredient in many Hawaiian dishes, adding flavor and spice to poke and stews. “At one time there were

Oceans of Opportunity for Hawai‘i’s Future

by Cary DeringerHawai‘i, an ocean-bound state, is just beginning to discover the myriad ways the sea can counteract increasing energy demands, dwindling fresh water supplies, and worsening food shortages. To see for yourself, visit Keāhole Point on the west coast of the Big Island just south of the Ellison Onizuka Kona International Airport. There you will discover the Hawai‘i Ocean Science and Technology (HOST) Park administered by the Natural Energy Laboratory of Hawai‘i Authority (NELHA), where about 80 percent of the state’s aquaculture and marine products are generated using ingenious ocean-based technologies. Originally founded in 1974 to provide a support

Cesspools in Paradise

by Helen RaineWe take the humble toilet for granted, rarely stopping to think about where all that waste goes. But in Hawai‘i, the reality for thousands of residents is that the plumbing leads straight to a big hole in the ground. There are approximately 88,000 aging cesspools across the state, and some of that untreated waste is making its way into our streams, oceans, and drinking water, leading to illness for swimmers, paddlers, and surfers, as well as stressing our coral reefs and native fauna. Change is on the horizon, however; some innovative new solutions have reached the testing stage

Xeriscaping Conserving Water One Garden at a Time

by Jackie DudockFrom Denver to Honolulu In 1981, inspired by a passion for water conservation and public education, a special task force of the Denver Water Department, Associated Landscape Contractors of Colorado, and Colorado State University kicked-off what became a national water-efficient landscaping movement. From this partnership, the term “xeriscape” was coined and began to be used to describe techniques that, when implemented cooperatively, significantly reduce landscape and garden water use. Xeriscape: from the Greek “xeros,” meaning dry, and “scape” meaning the pattern of the landscape. By 1982, the nation’s first public xeriscape demonstration garden and education program were in

Huli ‘ia is an observational process documenting seasonal changes and shifts across entire landscapes, ma uka to ma kai (from the mountains to the ocean). Developed by Na Maka o Papahānaumokuākea, the Huli ‘ia process documents these natural changes over time, identifies dominant cycles of important species or natural occurrences (e.g. flowering, fruiting, presence/absence of flora/fauna, cloud formations, spawning or recruiting of fish species, etc.), and assists in identifying any correlations between species and occurrences. Those correlations help to identify the occurrence of a less visible situation (e.g. fish spawning) when a more obvious one happens (e.g. a flower species

Resilience-Focused Disaster Reconstruction Planning

Hawai‘i’s coastal communities are particularly vulnerable to impacts from hurricanes, tsunamis, and other coastal disaster events due to the state’s isolated location in the Pacific and development concentrated along low-lying shores. Impacts from infrequent coastal disaster events will become more severe with climate change and sea level rise. Human impacts to coastal environments that act as natural barriers including beaches and reefs also makes our communities more vulnerable to impacts from storms and high waves. The ability to build back safer, stronger, smarter, and faster after a damaging disaster while considering potential impacts to natural and cultural resources is a

Integrating Coastal Hazards and Sea Level Rise Resilience in Community Planning

Over the past decade, Hawai‘i has progressed in recognizing and addressing coastal hazards and the need for adaptation to sea level rise. However, more work still needs to be done to translate broad-scale guidelines and scientific information into action at the local level. This project focuses on developing practical guidelines for incorporating resilience to coastal hazards and sea level rise into county general plans and community plans. In the context of this project, resilience is a community’s ability to adapt and thrive in the face of increasing coastal hazards, climate change impacts, and sea level rise through proactive planning utilizing
