Mr. Goto’s business has been greatly impacted by the closure of parts of the national park nearest to her. The eruptions activated a “code red” warning from the Hawaiian Volcano Observatory, and most of the Hawai’i Volcanoes National Park — the park that is home to Kilauea, and the state’s biggest attraction — has been closed to visitors since May 11. “There’s no way to tell how long the park will be closed,” said Jessica Ferracane, a public affairs specialist for the park, “but we will remain closed until it’s safe to reopen.”

The shutdown of the park alone is likely to cost the local economy millions of dollars. The National Park Service reported that by driving visitor spending on hotels, restaurants, grocery stores and rental cars the Volcanoes park contributed $166 million to the local economy in 2017.

Lynne Koontz, an economist with the National Park System, believes that the most precise way to measure the impact that the park’s closure will have on the local economy is by breaking down the annual figure into a daily average — $455,000 a day — and multiplying that by the number of days the park has been closed. The park has now been closed for 10 weeks, adding up to nearly $32 million.

Meanwhile, the eruptions have continued. Ms. Ferracane added by email that “every 24-36 hours there’s a significant collapse at the summit” because of a lava lake draining away, and that the draining triggers “earthquakes in the magnitude 5 range and higher,” which “continue to damage park infrastructure on a daily basis.”

But to Hawaii residents, tourists’ fears and their resulting booking cancellations are a source of deep frustration, owing to what they say is a fundamental misunderstanding of the geography of the state and overly alarmist reporting: The eruption is occurring in a rural, 10-square mile area in the southeastern corner of the most southeastern island of the state’s eight main islands. Honolulu, for example, is more than 200 miles from the erupting volcano.

“I believe we will lose customers,” said Joel Genavia, the assistant general manager of the Fishhopper restaurant in Kona, on the western side of the Big Island. The restaurant serves 500 to 800 people a day, 75 percent of whom are tourists, Mr. Genavia estimates. “I’m worried that this will mean that my workers, and other workers at tourism businesses around the island, are going to end up getting laid off,” he said.

Tourism provides 30 percent of the private sector jobs on the Big Island, causing concern to grow over the potential of a long-term hit on the island’s economy.
