|Storm Clouds Burst Over Kīlauea|
Lava is not the only spectacular natural event at Kilauea Crater. Storm Clouds seem to burst
over Kīlauea on Thursday. See more at https://www.facebook.com/hawaiivolcanoesnps

WITH ELECTRIC BILLS EXPECTED TO SOAR IN NEXT FEW MONTHS, Hawaiian Electric launched its Shared Solar Program on Friday. A statement from Hawaiian Electric says it is, "the latest phase of community-based renewable energy" for developers of small and large projects – including those tailored to low- and moderate-income customers. It is available for small projects (up to 250 kilowatts). Projects that qualify will be accepted in a four-month application window on a first-come basis up to the program’s capacity limit for each island.
“We’re excited to launch shared solar, designed to bring savings and a chance to participate in the renewable energy movement to many more customers, especially those who aren’t able to install a private rooftop solar system,” said Lani Shinsato, director of customer energy resources, programs. “To get the most out of shared solar, we need subscriber organizations – including nonprofits, homeowner associations and churches – to get involved so that these groups and those they serve can share in the benefits."
The available solar capacity of the shared solar program is over 250 megawatts, potentially including energy storage, across the five islands Hawaiian Electric serves. Some project sizes are limited in capacity. But mid-tier and large projects tailored for low- and moderate-income customers are not capped. Organizations that primarily serve such customers can apply to be a subscriber organization, which will recruit participants, and/or anchor tenants that participate directly in the solar savings. Details of the program can be found on our CBRE Resources page. A program guide for subscriber organizations that outlines the small project process can be found at hawaiianelectric.com/sharedsolar.

"After listening to community concerns about renewable energy project siting, regulators approved Hawaiian Electric’s request to allow residents who live near a large shared solar project the first chance at becoming subscribers," says the Hawaiian Electric statement.
WHILE COVID MAY APPEAR TO BE IN THE REAR VIEW MIRROW, Sen. Mazie Hirono issued a statement today on the one-year anniversary of President Biden signing the American Rescue Plan: "The devastating impact of the COVID-19 pandemic has affected communities in Hawai'i and across the country. The American Rescue Plan allocated crucial funding to help lower costs for families, address the housing crisis, and provide resources and support to respond to this public health emergency. In Hawai'i, the ARP provided $4.6 billion in aid to help our schools provide safe, in-person learning and address
"All of this would not have been possible without Democrats passing and President Biden signing the American Rescue Plan," said Hirono. She noted that Republican declined from voting "for this bill that helped American families. While this bill was a down payment to help families recover from COVID-19, there is still a lot of work to do. Families are still struggling with the impact of a global pandemic and a geopolitical crisis."To read comments, add your own, and like this story, see www.facebook.com/kaucalendar/.

MAGMA CHAMBER MUSIC CAN TELL A REVEALING TALE, according to Volcano Watch, the weekly column by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. This week’s article was written by California Volcano Observatory research geophysicist Josh Crozier:
In a lava lake, such as the one present from 2008–2018 in Kīlauea’s summit Halema‘uma‘u crater, we can sometimes visually observe these fluid motions as ripples or sloshing of the surface following disturbances from rockfalls or gas bursts.
We can also detect deeper magma motion by using seismometers to measure ground vibrations. The seismic signals generated by magma motion, such as the example shown in the figure, are often distinct from other types of seismic signals. Compared to normal earthquakes, magma motion usually produces relatively slow vibrations, where the ground rises and falls over several seconds or tens of seconds.
Magma or lava bodies vibrate most strongly at certain frequencies, called resonant frequencies, that depend on the body’s geometry and the properties of the magma or lava it contains, such as temperature and gas content. This is similar to how the musical notes produced by an instrument like a pan flute, bell, or a kāʻekeʻeke depend on the instrument’s shape and the properties of the air in it.
If a magma or lava is very fluid, for example like water rather than maple syrup, then a single perturbation can cause the magma body to resonate (vibrate or slosh at its strongest frequencies) for tens of minutes, such as the example shown in the figure.

Such resonance has helped to reveal Kīlauea’s shallow summit magma system geometry, for example suggesting that the conduit connecting its shallow summit magma reservoir with the overlying lava lake in Halema‘uma‘u from 2008–2018 was more than 50 feet wide. It has also revealed complex magma dynamics over the past decade, including convective overturns and melt supply pulses, which inform the restless nature of Kīlauea Volcano.
If you have a chance to stand near one of Hawaii’s active volcanoes, remember that the magma several kilometers beneath your feet could be subtly vibrating. And if visiting a volcano isn’t convenient, just tap on the side of a glass of water and watch the fluid resonance that results.
