A DETOUR FROM HWY 11 AWAY FROM KĪLAUEA CALDERA is necessary for public safety and teachers reaching schools, according to Civil Defense Director Talmadge Magno. He told Volcano Village residents at a meeting Thursday night that an emergency route will be built soon, taking motorists farther away from the caldera, with its earthquakes causing cracks and sink holes -- major damage to Hwy 11. While Hwy 11 is constantly under repair, a new route is "critical," said Magno. Magno explained that parts of Hwy 11 are inside Kīlauea
Caldera, which is subsiding, its floor dropping, its crater walls falling, making the nearby land under Hwy 11 unstable.
"We've been given a life-changing blow here. Whether you like it or not, we all gotta adjust, to make things still viable for our communities," said Magno.

Magno noted that of approximately 50 teachers in Ka`ū, 22 commute on Hwy 11 from the Hilo side. Without the highway, Ka`ū schools would shut down.
Children traveling from Ka`ū to Volcano School of the Arts & Sciences, Kamehameha Schools, and St. Joseph's also travel Hwy 11, as do many people from Ka`ū going to work and college in Hilo.
Magno said that more than half of police, fire department, and other personnel and equipment, come fromHilo side. He mentioned the importance of Hilo Hospital to the Ka`ū Community.

Magno also noted that the Volcano Village Golf Course community would be trapped if Hwy 11 was unusable.
Magno said the emergency route that would take the least time to build would leave Hwy 11 at Pi`imauna Dr. and turn right before Volcano Village Golf Course and Volcano Winery. It would use usually quietGolf Links Road ,
which parallels Hwy 11, to Old Volcano Road, where motorists would be reconnected to Hwy 11.

The second option would be farther from the caldera. Magno said it would probably take about three months to construct. It would use established roads - up Pi`imauna, turn northeast toward Mahiai Road and cross ranch land to
connect to Mahiai. The traffic would make a right at Wright Road, and reconnect with Hwy 11.

HOW LONG WILL KĪLAUEA 'S LOWER EAST RIFT ZONE ERUPTION CONTINUE? Volcano Watch, by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates, seeks to answer this question:
"How long will it last?" is one of the most challenging questions asked about a volcanic eruption, including Kīlauea Volcano's current lower East Rift Zone eruption.
The short answer is that no one knows for sure. Scientists can, however, offer the most likely possibilities based on characteristics of the current eruption and comparisons with past eruptions.
Fissure 8 spouts lava to fill a deceptively large and deep lava "river" that travels to the ocean. USGS photo |
The LERZ eruption started on May 3, 2018 . Over the next few weeks, a total of 2 4 vents briefly erupted, but only the 8th fissure, which initially opened on May 5 and reactivated on May 27, is still erupting today. On June 4, the fissure 8 lava flow reached Kapoho Bay, where a lava delta continues to grow as lava enters the ocean.
Knowing how much lava is erupting could help answer the duration question, but it's been difficult to measure the fissure 8 eruption rate. USGS scientists have used several techniques in recent weeks to obtain a rough estimate of 50 to 150 cubic meters per second (65–196 cubic yards per second), for a total erupted volume to date of 0.5 cubic kilometers (0.12 cubic miles).
A decreasing trend in this rate would suggest that the eruption might be ending -- or be over when the eruption rate gets too low to sustain ongoing activity. Unfortunately, scientists have not detected any trends. The eruption rate seems more or less constant, with some short-term variations.
Preceding the LERZ eruption, geophysical monitoring of earthquakes and ground deformation tracked the subsurface intrusion of magma under Leilani Estates. If scientists could detect decreases in the volume of that intrusion as fissure 8 lava continues to erupt from it, they could estimate the length of time after which the intrusion would be depleted.
But monitoring has detected no changes in the intrusion since its emplacement. This suggests that magma withdrawn by the fissure 8 eruption is being quickly replaced.

Scientists also turn to past eruptions for clues to possible duration. In the recent USGS hazard assessment of fissure 8, volcanoes.usgs.gov/vsc/file_

Kīlauea 's 2018 eruption was compared to four past LERZ events.
mngr/file-185/USGS%20Preliminary%20
Analysis_LERZ_7-15-18_v1.1.pdf,
The 1840 eruption, which lasted 26 days, had an average eruption rate similar to today's rate. In 1924, earthquakes and major subsidence in the Kapoho area suggested that magma had intruded the LERZ, but no eruption occurred.
A LERZ eruption in 1955 shared some similarities with the first three weeks of the current eruption. During the 88-day-long 1955 event, more than 20 fissures erupted in no clear order; in May 2018, 24 fissures erupted, also in no clear order. However, the average 1955 eruption rate was significantly lower than the present rate.
The most recent LERZ eruption occurred in Kapoho in 1960. It lasted about 5 weeks, and its eruption rate was less than half that of today's eruption.
As of July 31, the 2018 eruption has surpassed the 1955 eruption in duration and exceeded all but the 1840 event in eruption rate. So, scientists look to other Kīlauea eruptions for clues to how long the 2018 eruption could last.

Heiheiahulu, a shield-shaped vent similar to Kupaianaha, active 1986–1992, may have erupted in the early 18th century. It is located about 10 km (6 miles) uprift of fissure 8, and its lavas cover about 45 square kilometers (17 square miles). The similarity of its structure to that of Kupaianaha and Mauna Ulu suggest that Heiheiahulu erupted for several years.
Lava from Pu`u Kaliu, located 1.6 km (1 mile) uprift of fissure 8, covered about 12 square kilometers (4.6 square miles) with an estimated volume of 0.2 cubic kilometers (0.05 cubic miles). Puʻu Kaliu lava flows, thought to have erupted in 1790 from fissures on either edge of the LERZ, are similar to the 1840 flow.
Finally, scientists must consider Pu`u `Ō`ō, which lasted 35 years, 1983–2018, erupting a volume of 3.3 cubic kilometers (0.79 cubic miles), and Mauna Ulu, which erupted 0.2 cubic kilometers (0.05 cubic miles) of lava over 5 years, 1969–1974.
So, how long will the 2018 LERZ last? Based on past eruptions and current geophysical monitoring, it could continue for many months to a few years. Time will tell.
Volcano Activity Updates

On Kīlauea Volcano's lower East Rift Zone, lava continued to erupt primarily from fissure 8, feeding a channelized flow to the main ocean entry near Ahalanui Beach Park. At the coast, as of August 2, the flow remained less than 0.1 mile from the Poho`iki boat ramp at Isaac Hale Park. Sulfur dioxide emissions from the active fissure remain high. Residents in the lower Puna District of Hawai`i Island should stay informed and heed Hawai`i County Civil Defense closures, warnings, and messages; hawaiicounty.gov/active-alerts.
At Kīlauea 's summit, collapse events continued to occur during the past week, releasing energy equivalent to earthquakes of around magnitude-5.3. Ongoing subsidence of Halema`uma`u and adjacent parts of the caldera floor resulted in frequent felt earthquakes at the summit. Three or more felt reports were submitted for 51 of the earthquakes that occurred in Hawai`i during the past week.

HECTOR HAS GROWN TO A CATEGORY THREE HURRICANE. The National Hurricane Center predicts that by 5 p.m. Wednesday, Hector will be passing Hawai`i. Ka`ū is within the cone predicting the probable path of the hurricane. NHC says, "There is the potential for Hector to bring some impacts to portions of the Hawaiian Islands by the middle of next week, but it is too
soon to specify the magnitude of the impacts or where they could
occur. This is a good time for everyone in the Hawaiian Islands to
ensure they have their hurricane plan in place. For additional
information on any potential local impacts from Hector in Hawai`i,
please refer to products issued by the NWS Weather Forecast Office
in Honolulu at prh.noaa.gov/hnl."

KINDERGARTEN AND PRE-K SCHOOL SUPPLIES were delivered to Nā`ālehu
Elementary this morning by `O Ka`ū Kākou, a local community non-profit. OKK has
been donating supplies to local area schools for several years. "I can't
remember not having OKK's support (at school). Nā`ālehu school really
appreciates it," said Principal Darlene Javar.
"This
(donation) makes a big impact on kids and families. It takes the edge off
of the new year," added Kindergarten teacher Raina Whiting.
Javar shared that
the $1,100 donation of supplies covers any supplies Pre-K and Kindergarten
students might need to start the year. Even backpacks are covered, as Costco
will be donating a backpack for every student in the school. The first day of
school is Tuesday, Aug. 7.
SEN. MAZIE HIRONO'S MILITARY DOMESTIC VIOLENCE ACT was passed by Congress 87-10 on August 1, as part of the National Defense Authorization Act. The bill now goes to Pres. Trump to sign.

John Feinblatt, President of Everytown for Gun Safety said, "Domestic violence is domestic violence, and all convictions for this inexcusable crime should be recorded in the national background check system. We applaud Congress for taking action to close the Sutherland Springs loophole and prevent anyone convicted of domestic abuse from accessing guns."

Retired Marine Corps Combat veteran Kyleanne Hunter, Vice President of Programs at the Brady Campaign to Prevent Violence and co-founder of Veterans for Gun Reform said: "Making sure people who intend to do others harm like domestic abusers don't have access to guns is more than common sense -- as we saw in Sutherland Springs last year, it's an issue of national security. At Brady, we were proud to support bipartisan legislation to improve the nation's background check system in the wake of the Sutherland Springs shooting, despite the failed attempt by some lawmakers to co-opt this legislation with dangerous concealed carry language on behalf of the gun lobby. Sen. Hirono's bill, coupled with the FIX NICS law passed earlier this year, will further improve the military and Defense Department's ability to report dangerous, prohibited persons to NICS, and contribute to the security of the United States. We applaud and thank the senator for her leadership on this crucial issue."

WAIHO`OLU`U OLA: LIVING COLOR DYERY, a creative natural collective started by husband, Justin (the alchemist) and wife, Wai`ala (the artist), hosts a workshop on Saturday, August 25, from 12:30 p.m. to 3:30 p.m, at Volcano Art Center's Ni`aulani Campus in Volcano Village.
The workshop focuses on using traditional methods of banding and folding in traditional and modern Shibori styles to create patterns as participants explore the alchemy of indigo, a plant-derived pigment. Students will use a plant-derived indigo vat to dye material made from natural sustainable fibers and create Shibori resist patterns using folding, wrapping, and clamping techniques. Students will also learn how to control hue density with multiple dyeing submersions. Students will bring home new skills and understanding of indigo dye, as well as their own finished sample pieces.

Basic fundamentals of this historic dyeing process will be covered, with all materials provided. Participants may also bring 1-5 small items of their own to dye -- avoiding bulky or heavy pieces (i.e. towels, linens, yards of fabric, or bedding, etc.) as vat space and time are limited. The items brought should be cotton, linen, hemp, silk, or anything natural -- no synthetics -- as they accept the color best. Pre-wash items for best results.
The teaching duo also work together with other natural living color dyes: olena, avocado, hibiscus, and more. "Outside the joy of sharing the alchemy of natural dye in workshops with others, the two love sharing their love for the natural plant world and the process of co-creating consciously with nature," states Volcano Art Center's calendar listing.
See volcanoartcenter.org or call 967-8222 for more details. No experience necessary. Space limited. Pre-registration required. Class is $50 per Volcano Art Center Member or $55 per non-Member, plus $25 supply fee.
