Volcano Watch: Think Hawaii has many volcanoes? Think again, says El Salvador – West Hawaii Today


This past March, a team of U.S. Geological Survey scientists — two of whom travelled from Hawaii — visited El Salvador in Central America for volcanological field studies and a workshop on lava flow hazards. Exchanges like this help to improve awareness of volcanic hazards in other countries, and they enable the USGS to better understand volcanoes in our own backyard.

El Salvador is the smallest country in Central America, sitting on the Pacific coast and measuring slightly larger than all the Hawaiian Islands combined.

However, the eight main Hawaiian Islands are comprised of only 15 volcanoes above sea level; El Salvador, on the other hand, has over 200! And that’s with a population of about 6 million people, about four times as many as Hawaii.

There are numerous volcanoes in El Salvador because it sits along the Central American volcanic arc, rather than atop a hotspot like Hawaii. Volcanic arcs form where an oceanic tectonic plate subducts beneath either a continental plate or another oceanic one; the ocean crust triggers melting as it dips into the Earth’s mantle, creating magma that rises to the surface through the overlying plate. Though El Salvador has five larger volcanoes with historical eruptions, numerous fault lines allow magma from the subduction zone to emerge just about anywhere. This has resulted in hundreds of smaller volcanoes, most of which have erupted only once.

Volcano monitoring in El Salvador is handled by the Ministerio de Medio Ambiente y Recursos Naturales (MARN). In addition to tracking the weather and other natural hazards, a small team of volcanologists works to study the geological and geophysical dynamics of the country’s volcanoes, while maintaining a watchful eye for signs of unrest. The stratovolcanoes of Santa Ana and San Miguel have both erupted in the past 25 years, but even more destructive events have occurred in the not-too-distant past: San Salvador volcano sent a lava flow into presently developed areas in 1917, and Ilopango caldera had a regionally devastating eruption in the year 431.

USGS, through its Volcano Disaster Assistance Program (VDAP), has maintained a collaborative relationship with MARN for decades. Co-funded by the U.S. Department of State, VDAP has supported numerous technical investigations and monitoring projects at volcanoes in developing countries around the world. Meanwhile, many MARN volcanologists have even studied in the United States as part of the Center for the Study of Active Volcanoes (CSAV) course held every summer in Hawaii and Washington state.

In recent years, VDAP’s relationships in El Salvador have focused on geologic projects to describe the eruptive history and hazards of Santa Ana volcano and a broader effort to assemble a national “volcano atlas,” which will include locations, compositions, and — hopefully — approximate ages for the more than 200 volcanic vents in the country. Such knowledge will enable more accurate understanding and delineation of hazards associated with their eruptions, which are both explosive (ash-producing) and effusive (lava flow-producing).

The field work in March served both projects. Dozens of samples were collected to correlate and date eruptive deposits across Santa Ana, including three sediment cores from coastal mangroves and a montane bog that may contain distant ashfall from the volcano. Reconnaissance visits were also made to several monogenetic (single-eruption) vents scattered around western El Salvador to assess their genesis and ages.

Finally, VDAP sponsored a weeklong workshop on lava flow hazards and monitoring for MARN staff and partner agencies. Since El Salvador’s last lava flow erupted in 1917, none of the current team have responded to such an event. USGS scientists from the Hawaiian, Cascades, and Alaska Volcano Observatories discussed their experiences and best practices developed during recent eruptions at Kilauea and Mauna Loa in Hawaii, as well as Great Sitkin and Pavlof in Alaska.

While the USGS scientists learned plenty about volcanism in El Salvador during this trip, it also provided key insights to bring home to our own volcanoes. Explosive eruptions in Hawaii are relatively rare, but the ability to correctly interpret their deposits is critical to understanding potential future hazards. Additionally, the more distributed nature of volcanoes in El Salvador has led to interesting interactions between lava flows and their more-weathered depositional environments, not unlike some of Hawaii’s older volcanoes: Hualalai, Mauna Kea, and Haleakala. We thank MARN for the opportunity to visit and study their country’s volcanoes.

Volcano
activity updates

Kilauea has been erupting episodically within the summit caldera since Dec. 23, 2024. Its USGS Volcano Alert level is ADVISORY.

Episode 46 of summit lava fountaining happened for nine hours on May 5. Summit region inflation since the end of episode 46 indicates that another fountaining episode is possible but more time and data is needed before a forecast can be made. No unusual activity has been noted along Kilauea’s East Rift Zone or Southwest Rift Zone.

Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL.

Principal honors Obama as ‘Child of Hawaii’ at library opening – AsAmNews


The honor of introducing former President Barack Obama at the grand opening of his new presidential library in Chicago Thursday went to Dr. Kaiwipunikauikawēkiu Punihei Lipe of Hawaii.

Hawaii News Now reports that Lipe participated in the inaugural cohort of the Asia-Pacific Leaders Program in 2019 and is currently the principal at Kamehameha Schools Kapālama.

“Where I come from, to introduce someone means we have pilina, a connection. If this man walked into my home, my children would call him uncle because we are both keiki o ka ʻāina, children of Hawaii,” she said in her remarks.

She told those in attendance that the former president and herself are both “children of Hawaii.” Obama lived on the island and attended Punahou School and lived in Hawaii for eight years until his graduation from high school.

Lipe said being children of Hawaii carries with it a “sacred responsibility to care for those who we may never meet.”

She made reference to the resilient Hawaiian shrub, the Like a’ali’i.

“The a’ali’i thrives by being deeply rooted, resilient through storm and drought, and fiercely responsive. That is what ‘yes, we can’ means to my indigenous heart. It demands that we remain unshakably rooted in truth, resilient through trial, and so responsive that just as this plant yields its leaves for medicine, its blooms for beauty, and its timber for protection, we become the healing, the vibrance, and the shelter needed by our communities and by grandmother earth.”

Ambassadors of aloha: Food events aim to boost tourism with unique Hawaii-made products


HONOLULU (HawaiiNewsNow) – It’s shaping up to be a slower-than-usual summer for Hawaii’s tourism industry, but business leaders hope events that market the islands’ unique local food and products can turn that around.

The state expects total visitor arrivals to grow only about 2 percent this year. Numbers slid half a percent in April from the previous year, with the largest market, West Coast tourists, falling nearly 5 percent. The statewide hotel occupancy rate averaged 76.4 percent.

Economists blame higher airfares, rising inflation, fewer international visitors and uncertainty following the March kona low storms.

State-supported events like the Hawaii Lodging & Tourism Association’s (HLTA) Hawaii Hotel and Restaurant Show and DBEDT’s Hawaii Made Conference aim to boost tourism by promoting products you can only find in Hawaii.

“We’re going to continue to struggle, but we can’t stop promoting. We can’t stop advocating,” said HLTA President/CEO Mufi Hannemann. “If you can travel during these times, you’re going to come and have a wonderful experience in Hawaii whether you’re just coming for sun and surf or you’re coming here to immerse in our culture or to do business, this is the place to come.”

And those who do come are spending more.

At the Hotel and Restaurant Show this week, local food manufacturers hoped to secure more buyers in the hospitality industry.

Many rely on business and leisure visitors trying their products while in Hawaii and taking them back home where they promote it.

“The traceability that you want to know where your food is coming from,” said June Rees, general manager of Kauai Shrimp, which has 40 ponds off the coast of Kekaha. You’ll find their shrimp on many menus across the islands.

“There are a lot of people that heard about us but never tried, so this show gives us exposure to the new restaurant or chef that have heard about the name but never really tried the product.”

But fewer tourists mean less sales and slower business growth and investment.

Jina Wye is the founder of Okonokai, which makes snacks from native seaweed grown off the Kona coast on Hawaii Island.

“It’s like a superfood that everyone should be eating everyday,” she said. “There’s a lot of just missing infrastructure for manufacturing, but that’s something that we’re working on. It’s actually why I’m part of this whole like DBEDT pavilion because the state is really working hard to develop more infrastructure.”

For the family behind Aloha Star Coffee Farm, getting their award-winning premium kona coffee into airports, hotels and restaurants is key.

“Getting the opportunity to find the market niche that we need,” said Karina Rodriguez, co-owner of Aloha Star Coffee. “We are small, that sometimes we don’t have all the resources for marketing and, and going to the biggest stores, and we are working on that.”

Food entrepreneurs will get another chance to promote their products at DBEDT’s Hawaii Made Conference this Tuesday at the Sheraton Waikiki. Click here to register and for more information.

The 16th Hawaii Food & Wine Festival is another event that promotes local chefs and restaurants while promoting tourism. It spans three weekends from Oct. 16 to Nov. 8 across three islands. Find information here.
