The old way of voting, like going behind the curtain to personally cast the ballot at Kaʻū High & Pāhala Elementary, is gone with candidates hoping that everyone will vote through the mail by Nov. 3 or go to drop off stations in Na'alehu, Hilo, Kona and other towns around the island.

For this election some results are already final. Representing Volcano through Kaʻū and Miloli'i into Kona will be County Council member Michelle Galimba and state Sen. Dru Kanuha who won the primary election in August.
In the General Election, voters from Volcano through Kaʻū and Miloli'i into Kona will have the choice of voting for the person to serve them in the state House of Representatives, District 5. The candidates are Republican Lohi Goodwin, Democrat Jeanne Kapela and Libertarian Michael Last.
For the U.S. House of Representatives, voters in this area and all of rural Hawai'i will choose between Republican Joe Akana, Libertarian Michelle Rose and Democrat Jill Tokuda.
For U.S. Senate, voters throughout Hawai'i will choose between Libertarian Feena M. Bonoan, Aloha 'Aina Party candidate Dan Decker, Republican Bob McDermott, Green Party candidate Emma Jane A. Pohlman and Democrat Brian Schatz.
THREE AMENDMENTS TO THE COUNTY CHARTER are on the back of the State of Hawai'i, General Election Ballot, sent out in the mail and due Nov. 8.
The first asks the voters: "Shall the Hawai'i County Charter be amended to increase the membership of the Board of Ethics from five members to seven members?"
The third proposed amendment asks the voters: "Shall the Hawai'i County Charter be amended to establish a Youth Commission, which would consist of at least nine but no more than 15 members between the ages of 14 and 24-years old, whose duties would include advising the Mayor, County Council, and official agencies of the County on legislative and budgetary matters, assess existing programs and advance new programs that support youth development, and encourage and coordinate youth participation on County initiatives and other forms of civic engagement?"

THE ALMOST CONTINUOUS SUMMIT ERUPTION at Kīlauea volcano turned one-year old on Sept. 29. Volcano Watch reports that the "past year’s activity has commonly been described as continuous effusion of lava within Halemaʻumaʻu crater. Although this has been mostly true—especially in recent months—there have been multiple occasions when lava was not flowing. What happened at those times, and why?"
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. Here is this week's edition:
During the late fall and winter of 2021–2022, the Kīlauea eruption would episodically pause for periods lasting from hours to days. These pauses typically occurred in conjunction with deflation-inflation (DI) events in the summit magma reservoir, as recorded by USGS Hawaiian Volcano Observatory tiltmeters in the region.
As the summit deflated the surface of the active lava lake would drop, eventually settling about 10 meters below the rim of the surrounding levees. At this point the lava would crust over, except for a small active pond near the western eruptive vent. Notably, during each pause there was also a substantial reduction in sulfur dioxide (SO2) emissions, suggesting that little to no magma was rising in the shallow conduit below the eruptive vent.
When the summit reinflated to a critical point, lava would flow from this pond to slowly refill the lava lake. Surges of lava followed many of the pauses and often caused overflows from the active lake onto large sections of the surrounding crater floor. Breakouts of lava from around the circumference of the crater floor were also common during eruption restarts. These events were responsible for significantly thickening the crust making up the current crater floor.
Why did these pauses occur? HVO scientists are still exploring this question. The pauses were clearly associated with DI events during this period. However, many other DI events occurred both before and after the period of pauses last fall and winter. The Deflation-Inflation events associated with pauses were not particularly large and some were tiny compared to many of those that preceded and followed the period of pauses. It remains curious why some of these DI events shut down the eruption while others caused only minor fluctuations in activity.

The last pause to date occurred on March 18, and since then there has been truly (or mostly truly) continuous lava effusion. The crater floor has also continued to rise due to lava spreading from the active lake to areas beneath the crust. This “endogenous” injection of lava lifts the crater floor, like the inflation of an air mattress.
The eruptive activity at Kīlauea summit was disrupted one more time on Sept. 20, when a swarm of several dozen earthquakes occurred below Halemaʻumaʻu. Simultaneously, tiltmeters measured rapid inflation in the summit region. Around 4:30 p.m. webcams recorded the higher central part of the crater floor dropping by several meters at the same time breakouts occurred along the lower margins of the crater floor. The earthquakes and inflationary tilt soon tailed off followed by the return of steady activity within the lava lake.
Initial observations suggested that the conduit to the eruptive vent may have experienced a structural failure—allowing dense lava below the crater floor to infiltrate the conduit, causing it to clog. Geophysical data from this event and the following days tell a very different story. Interferometric Synthetic Aperture Radar (InSAR) data from satellites show that an area around the west side of Halemaʻumaʻu crater uplifted by a couple centimeters around Sept. 20. Modeling of the seismicity and deformation by HVO scientists indicates that a horizontal body of magma, called a sill, may have been intruded between old layers of lava below the crater that day.
Over the past week, lava has continued to erupt from the western vent within Halemaʻumaʻu crater in Hawai‘i Volcanoes National Park. Sulfur dioxide emission rates remain elevated and were last measured at approximately 1,800 tonnes per day (t/d) on Sept. 30. Seismicity is elevated but stable, with few earthquakes and ongoing volcanic tremor. Over the past week, summit tiltmeters recorded two deflation-inflation (DI) events.

| This reference map depicts the ongoing Kīlauea summit eruption on Oct. 7. One eruptive vent (orange) is active within Halema‘uma‘u, on the western side of the crater floor. An adjacent pond (purple) is feeding lava to a larger lake (red) via a crusted-over tube. The eruption statistics provided were as of the HVO overflight on Oct. 5. Citizen scientists may notice that the eruptive features and statistics provided here are mostly unchanged from the reference map on Sept. 13. This is because a magmatic intrusion below Halema‘uma‘u on Sept. 20 caused some lava to drain from below the crater floor. In the time since, lava has refilled to about the same level as before, and there have been no further ooze-outs to expand the footprint of lava flows from this eruption. Lava is presently visible from three public visitor overlooks in Hawai‘i Volcanoes National Park: Keanakāko‘i Overlook and Kūpina‘i Pali (Waldron Ledge) can see the eruptive vent and lava lake, while Kīlauea Overlook can occasionally see lava ooze-outs in the southeast part of the crater.

During the week ending Friday, about 245 small-magnitude earthquakes were recorded below the summit and upper elevation flanks of Mauna Loa—the majority of these occurred at shallow depths less than 15 kilometers (9 miles) below sea level. Global Positioning System (GPS) measurements show continued ground deformation consistent with inflation of a magma chamber beneath the summit. Gas concentrations and fumarole temperatures at both the summit and at Sulphur Cone on the Southwest Rift Zone have remained stable over the past week. Webcams show no changes to the landscape. For more information on current monitoring of Mauna Loa, see: https://www.usgs.gov/volcanoes/mauna-loa/monitoring.
There were 13 events with three or more felt reports in the Hawaiian Islands during the week ending Friday. Listed here are the felt events with magnitudes of 3 and above: a M3.1 earthquake 25 km (15 mi) E of Honaunau-Napoopoo at 0 km (0 mi) depth on Oct. 16 at 7:36 p.m. HST, a M3.6 earthquake 9 km (5 mi) S of Pāhala at 12 km (8 mi) depth on Oct. 14 at 3:05 p.m. HST, a M3.9 earthquake 6 km (3 mi) S of Pāhala at 10 km (6 mi) depth on Oct. 14 at 10:12 a.m. HST, a M4.0 earthquake 9 km (5 mi) SSW of Pāhala at 11 km (6 mi) depth on Oct. 14 at 9:16 a.m. HST, a M5.0 earthquake 7 km (4 mi) SSW of Pāhala at 8 km (5 mi) depth on Oct. 14 at 9:07 a.m. HST, and a M4.6 earthquake 8 km (5 mi) S of Pāhala at 11 km (7 mi) depth on Oct. 14 at 9:07 a.m. HST.
