LOWERING HIGHER EDUCATION COST is a goal of state Sen. Kai Kahele, who represents Hilo but has family roots in Miloli‘i, where he works on education and cultural programs. Kahele is pushing for reduced financial burdens for students attending schools in the University of Hawai
According to Kahele, even textbooks are a serious financial impediment for attending college. He said he spoke to hundreds of students who shared that textbooks, cost an average of $1,200, annually. His bill in the legislature calls it "a barrier to their higher education aspirations."

SB 2329, also making its way though the legislature, seeks to cap increases in tuition based on Hawaiʻi's median household income. A hearing is scheduled for Feb. 13, and testimony is welcome online, through the mail, and in person.
"Together," said Kahele, "these two senate bills are a culmination of the idea in which reasonable access to higher education is not only needed, but feasible. By easing the financial burden of receiving a higher education, one can focus on what is more important: an affordable, accessible, and quality education here in Hawai ‘i ."
He invites residents to provide testimonies via the capitol site, and to contact him or his staff with any questions at 586-6760 or senkkahele@capitol.hawaii.gov.

GRID MODERNIZATIONS FOR HAWAIIAN ELECTRIC COMPANIES that serve the counties of Hawai‘i, Maui, and O‘ahu, won approval from the Public Utilities Commission on Feb. 7. The PUC described the plan as "a holistic view of how Hawaiʻi's electric grid can evolve." According to HECO, it will improve reliability and develop island grids that are ready for more renewable energy sources, including rooftop solar adoption.

Senior vice president for planning and technology at Hawaiian Electric, Colton Ching, called the plan "customer-focused" and said they participated, along with technical experts and other stakeholders from Hawai‘i and the mainland. The PUC called for more customer participation and HECO complied.

The cost of carrying out the first segment of the plan is $205 million over the course of the next six years.
HECO first plans to acquire: more voltage management tools, to handle circuits with heavy solar penetration; advanced inverter technology, so more private rooftops can be integrated; enhanced outage management and notification technology; and strategic distribution of advanced meters for more accurate usage data. This will serve customers who want to participate in demand-response and variable rate plans, and those who seek usage data.

"SOUNDS WE CAN'T HEAR TEACH US ABOUT LAVA LAKES," declare USGS Hawaiian Volcano Observatory scientists in this week's Volcano Watch:
Visitors to Hawaiʻi Volcanoes National Park's Jaggar Museum Overlook when the wind is calm might be able to hear the sounds of gas bubbles bursting and lava splashing in the Halemaʻumaʻu lava lake at the summit of Kīlauea. What is heard is only part of a rich chorus of sounds emitted from many processes near the surface of an active lava lake.
While some lava lake sounds are audible, most of them are at frequencies below what humans can hear, called infrasound. As with the electromagnetic spectrum, in which long-wavelength infrared is just below the visible light range, infrasound is at frequencies below 20 Hz (Hertz, a measure of audio frequency), which human ears cannot hear.

Active volcanoes produce abundant sounds at or near Earth's surface. So, it can be beneficial to record those sounds using both seismometers for the seismic waves and microbarometers for the infrasound. Microbarometers are similar to sensors that measure pressure changes from passing weather fronts, but detect much smaller-scale changes in pressure.
So, what's the connection to lava lakes? At Halemʻaumʻau, the loudest sounds are about 1 Hz and can only be captured with dedicated infrasound recording equipment. A frequency of 1 Hz is about the same as that of strong seismic tremor produced at the volcano's lava lake and within the magma plumbing system. Seismic and infrasound sensors record different versions of this tremor and can be used together to better understand it.
One important difference between seismic and infrasound recordings is the pathway between the source and the recorder. Imagine all the layers of old lava flows off which a seismic wave echoes as it travels through the ground. Each of those echoes arrives at the seismometer at a different time and may result in a complex signal even if the source is simple.
On the other hand, the sound wave in the air has a much simpler path, as long as it doesn't have too far to go. For a source that sends waves through both the ground and the air, this means that infrasound signals are often much easier to interpret.

The blue line is an infrasound recording of 50 seconds of similar activity. Each peak in the graph represents the sound made by such a bubble burst. USGS photo by M. Patrick; infrasound data courtesy of G. Waite |
At Kīlauea's summit lava lake, there are times when each big bubble burst can be distinguished individually on an infrasound recording, but the overlapping seismic recordings of the same processes are much too complex to interpret alone. In this way, joint recordings of waves through the air and the ground can be used in the identification of small events in the seismograms.
Another way infrasound and seismic data can be used together is in monitoring the rise and fall of the lava lake. Since sound waves travel more slowly through the air than through the earth, the change in source location as the lake goes up or down means that the time it takes an infrasound signal to arrive at the recorders will change more than the change in time for the seismic wave. Using a little algebra, the change in the depth of the lava lake can be easily calculated. This is especially useful at volcanoes where the lava surface is not visible and cannot be measured more directly.
Infrasound has many applications on volcanoes beyond studies of lava lakes, as described in a previous Volcano Watch (https://volcanoes.usgs.gov/observatories/hvo/hvo_volcano_watch.html?vwid=128 ). In particular, infrasound can aid monitoring by continually tracking the directions from which sounds originate, potentially alerting scientists to the onset of new eruptive activity.
It takes a wide array of sensors to monitor an active lava lake. The ability to capture sounds we can't hear provides a wealth of information we wouldn't know we were missing.
