Lev’s team was prepared to support the effort and offered both sophisticated drones and reinforcements to relieve the already exhausted UH-Hilo team, the USGS scientists, and emergency-response workers.
“We had brand new equipment. It was an opportunity for us to try it within the context of a dynamic event for the first time. Our drone has both a standard video camera and an infrared video camera. It was very helpful because the team in Hilo had similar equipment but not a single drone that could conduct both video and the thermal imaging at the same time. To get that coverage they needed two flights. Using our equipment was faster and more efficient,” added Lev.
The three-person Lamont team also joined shifts as the necessary 24/7 monitoring continued.
“While we were not allowed to fly our drones ourselves, we could serve as the required flight observers, help with the setup and provide equipment, so the official responders could have a break. Our team helped reduce the load on them,” said Lev.
Ultimately, the eruption forced the evacuation of thousands of people. The lava flow consumed 700 homes. A series of as many as 18,000 earthquakes forced the closure of Hawai’i Volcanoes National Park, and lava haze (“laze”), spatter, and lava bombs became serious health threats. For volcanologists, however, the Kilauea eruption – more than 100 days long – was also an opportunity to study an enigmatic planetary process as it unfolded.
“For those of us grounded in the academic theory of what lava does and the physics behind lava flows, it was fascinating to see the response on the ground. We were part of it all, what the road crews have to deal with, what the fire crews have to deal with, how the community responds, and how people evacuate or don’t evacuate. Seeing all of this unfold and not just reading about it was really fascinating. People think lava moves slowly, that it’s not a rapid-response emergency. But actually, at Kilauea, things kept changing. Overall, 22 fissures erupted, and the active sites kept jumping around. The response had to be very dynamic. Many times I thought a fissure was done, but then it would start again. It was really about responding to what was happening,” Lev said.
Lev has been studying the science of volcanoes since her arrival at Lamont in 2009, but her work at Kilauea was revelatory for her.
“It’s different experiencing something with your body and your eardrum from thinking about it mathematically”, noted Lev. “It was definitely the most emotional connection to my subject that I’ve had…ever. For us that was the greatest benefit from going there, a chance to develop an intuitive connection to a subject we’ve long been studying from afar.”
Lev believes these observations and the ongoing sampling led by the USGS will inform volcanology, advancing science’s understanding, improving predictive modeling, and strengthening the case for a uniform methodology for responses to eruptions elsewhere. In the spring, during the weeks prior to the Kilauea eruption, she had been part of a cadre of volcanologists working on a proposal to the National Science Foundation to fund a data sharing and response coordination system. After her work on the front lines at Kilauea, she believes even more strongly that such a system is essential.
“The response was so complex at Kilauea, in the United States, a modern country with modern systems, and still there was room for improvement. This eruption and the response to it should serve as the model and a lesson for the future.”
