ALTERNATIVES TO VOLCANO BOX HOW TO
I will show you how to create a volcano plot by using RNA-seq data. Lundblad plans to keep bringing geology students out the park for leveling as long as they want to take advantage of the unique experience.A volcano plot is a type of scatter plot that is used to plot large amounts of data, such as RNA-seq data. However, in the past two years, the northern mile showed consistent tilting from north to south of about 15 centimeters due to a dike intrusion, which is when magma fills in cracks in the earth and pushes the surface up. I mean, they built an extra lookout for this current eruption, because you can’t keep people away from the lava.”Īfter hours of measuring about two miles of fault line, students found that there has been very little change, about 3 millimeters of elevation change, over the southern mile of the survey line in about two years. “There is just something so captivating about volcanoes. “I was so happy when the volcano finally erupted,” Mecham said.
Mecham started school right after the 2018 eruption stopped and wasn’t privy to an eruption until December 2020, when Kilauea began spewing lava again. I remember learning about them as a little girl, and I’ve been hooked ever since.” “Volcanoes have been a life-long obsession for me. “This is the best place for geology, and when an eruption starts, that’s the best thing that can happen to us,” Mecham said. The opportunity to actively work on actual volcanoes and decipher data is what led Ski Mecham to go to UH-Hilo to study geology. “It’s memorable out there if nothing else,” Lundblad continued. I think it helps allow them to ask questions and learn things in a different way. “It’s a good cohort building experience for all of us. They get tired of listening to us, and it’s nice to have other perspectives,” Lundblad said. “The interaction is really good for students. Geology students also have been able to work with HVO and talk with some of the leading experts in volcanology, which include alumni. “We are doing research, but the larger part is getting the experience and discovering what is involved with data collection.” “This is not a primary job of a geologist, but it’s nice to learn these methods, especially since they haven’t had much of chance to get into the field,” Lundblad said. “I’ve always been interested in volcanology, so I love being out here and learning from experience.”Īlthough geologists are not physically using the leveling technique like they used to, this opportunity gives students a chance to go out in the field, become physically involved in geology, and help HVO by providing data. “We’re doing the grunt work when we get to come out here and learn what actual geologists do on a daily basis,” said student Baylee McDade. Manpower is definitely needed, since the students have to carry two large measuring rods and locate the pins where they will make their measurements - all while navigating over rough terrain. What we do is manpower-intensive, and HVO just doesn’t have the time for that now.” “It’s slowly been replaced by other types of instruments, like GPS and satellite. “This type of geodesy we are doing, measuring the earth, is an old-school method that folks at HVO did forever,” Lundblad said. Lundblad began bringing students to Hilina Pali for leveling after the eruption in 2018, since it is one of the few places where people can see faulting that has gone on for several hundred years. “We get to see places that people never get to see and actually calculate if there is a change and contribute that data to (the Hawaiian Volcano Observatory).” “It’s tedious, but therapeutic,” said student Teagan Maher. The experience gives the students a glance into a life as a geologist. Leveling is the physical measurement of the elevation between two points on a fault line, and the calculation of the relative amount of vertical change. Led by geology professor Steven Lundblad, the University of Hawaii at Hilo geology students spent most of their day leveling fault lines in Hawaii Volcanoes National Park.
