LavaTalk: September 26, 2014 update on Kilauea’s lava flow


Latest USGS/HVO lava flow maps

USGS/Hawaiian Volcano Observatory Kilauea Status Update for 5:17 p.m. Friday, September 26, 2014

Volcanic Activity Summary: The June 27th flow front is stalled 2.3 km (1.4 miles) upslope from Apa`a St. and 3.3 km (2.1 mi) from Pāhoa Village Road; however, fresh lava broke out of the tube 5.4 km (3.4 mi) behind the flow front, suggesting that lava is slowly reoccupying the tube. Minor activity continues at several locations between the fresh breakout and the flow front in the form of residual lava oozing from the flow margins. The stalled leading edge of the flow was approximately 16.4 km (10.2 miles) straight-line distance from the vent. Because the flow did not advance over the past few days, we do not offer a projection of its future movement. These estimates will be revised after our next overflight, now scheduled for Monday.

Pāhoa town is in the Puna District of the County of Hawai`i.

Recent Observations: Leading edge of the lava flow is stalled at the flow front, but fresh lava is being resupplied through the tube to a breakout point 5.4 km (3.4 mi) behind the stalled leading edge.

Hazard Analysis: Lava flow from Pu‘u ‘Ō‘ō vent stalled but remained active with fresh lava being supplied behind the front.

Remarks: The Pu‘u ‘Ō‘ō vent in the East Rift Zone of Kīlauea Volcano began erupting on January 3, 1983, and has continued erupting for more than 31 years, with the majority of lava flows advancing to the south. Over the past two years, lava flows have issued from the vent toward the northeast. The June 27th flow is the most recent of these flows and the first to threaten a residential area since 2010-2011. On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘Ō‘ō cone and fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad. This sequence was repeated three more times over the following days with lava entering and filling other cracks before reappearing at the surface, in two of the cases farther downslope. Lava emerged from the last crack on September 6, forming a surface flow that initially moved to the north, then to the northeast, at a rate of 400 m/day (1,300 ft/day). The flow slowed thereafter and, between September 12 and 19, the rate of advancement varied, averaging 225 m/day (740 ft/day), finally stalling over the past week.

Hawaii County Civil Defense Eruption Update for 8:45 a.m. Friday, Sept 26, 2014

This morning’s assessment shows the leading surface lava flow has remained inactive and has not advanced. The small breakout flow upslope from the leading edge along the North flank also appears to be slowing and decreasing in activity. That breakout has advanced approximately 35 yards since yesterday and remains further upslope and to the North and does not pose an immediate threat to area communities.

No evacuation is needed at this time and area residents will be given adequate notice to safely evacuate should that be necessary.

HELCO crews will be working in the Government Beach road area and digging holes to allow for the installation of power poles. This will result in the road being blocked and the access will be limited to beach road residents only to minimize disruption and delays to the operations.

The public is reminded that the flow is not visible and cannot be accessed from any public areas. Access to the Kaohe Homesteads subdivision will remain restricted to area residents only.

We would like to thank everyone for your patience and understanding and your cooperation and assistance is greatly appreciated.

AMERICAN LUNG ASSOCIATION WARNS OF HEALTH EFFECTS FROM SMOKE

The American Lung Association in Hawaii warns visitors and people living near the lava flow in Puna to take precautions against smoke exposure from burning vegetation and low levels of sulfur dioxide.

This smoke is a mixture of gases and fine particles released as vegetation burns. In addition to burning your eyes, these fine particles and gases can be inhaled deeply into your lungs, making it harder to breathe.

Exposure can worsen other chronic health conditions such as asthma or heart disease.

Exposure to sulfur dioxide, a gas emitted by volcanoes, can also be harmful, burning the nose and throat and causing breathing difficulties.

Residents with respiratory problems such as asthma, chronic obstructive pulmonary disease (COPD), and also those with chronic heart disease should take extra precautions during this time and call their physician immediately if problems develop.

“Even those without lung diseases may be at risk during this time,” said Kim Nguyen, Executive Director of the American Lung Association in Hawaii. “With exposure to smoke, there is an increased risk of dangerous health effects ranging from respiratory tract irritation to more serious illness, including reduced lung function, bronchitis, worsening of asthma, and premature death. This is especially true for children, older adults and outdoor workers.”

People living near affected areas are encouraged to do the following:

  • Stay inside as much as possible, with doors and windows shut. Make sure only clean air circulates through air conditioners and/or air cleaners by using the recirculation setting.
  • When driving through smoky areas, car windows and vents should be kept closed. Air conditioning should be set to “recirculate” to avoid exposure to unhealthy outside air.
  • Avoid exercising outdoors, particularly if you smell smoke or experience eye or throat irritation.
  • Individuals with asthma are encouraged to contact their physician regarding any changes in medication they may need to cope with smoky conditions. The American Lung Association advises asthma patients who cannot reach their doctor to continue to take their medication and closely follow their asthma action plan as prescribed.

If you have questions, you can call the American Lung Association’s Lung HelpLine at 1-800-LUNG-USA (choose option #2) to speak to a lung health expert.

HAWAII ISLAND HUMANE SOCIETY

Unpredictable lava flows remind us that upfront planning now can ease stressful situations should there be a need to evacuate. As Benjamin Franklin once said, “An ounce of prevention is worth a pound of cure.”

The Hawaii Island Humane Society has a few tips to help keep animals safe in the event of an evacuation:

HIHS encourages all pet owners to be safe and prepared. If you are advised to evacuate, please consider your pet’s safety. Do not leave animals behind.

Develop a plan for their ongoing care including transportation arrangements.

Larger animals including horses and livestock may need to be moved well in advance. Call friends or family members to locate alternate pastures.

Gather items for your pet’s emergency kit –

  • Crate
  • Leash
  • Food
  • Water
  • Towel
  • Identification
  • Medication (if applicable)

If you evacuate, arrive at your destination prepared with your pet’s emergency kit and take your pets!

The mission of the Hawaii Island Humane Society is to promote respect for all animals, prevent cruelty to animals, eliminate pet overpopulation, and enhance the bond between humans and animals. HIHS holds a contract with the County of Hawaii to enforce certain animal-related laws and it offers 24-hour service for injured animals and other animal emergencies, humane education classes, low-cost spay and neuter services, lost and found assistance, micro-chipping and more.

For further information, call 808-329-1175 or visit www.hihs.org

HelpPuna.com Helps Animal Evacuation

The June 27 lava flow poses a threat to farms and homes in the Puna area near Pahoa. Since this flow is in an agricultural area, it also threatens farm animals such as chickens, ducks, sheep, goats, horses, pigs, in addition to dogs and cats.

All these animals would need to be evacuated in the event of an approaching lava flow. As people prepare for possible evacuation, they need to prepare and plan for evacuating their livestock and pets, too.

Finding accommodations for displaced people and their animals could become a major challenge as this lava flow continues. H.E.L.P. Puna is providing a free website service for residents who need to find places to protect their animals, and other residents in safe areas who wish to offer their properties as “Places of Refuge”.

H.E.L.P. is the Hawaii Evacuation of Livestock and Pets, a program of the Good Shepherd Foundation, a nonprofit organization with an animal sanctuary in Opihikao, not far from the lava flow.

Everyone is invited to offer their property as a haven from the lava flow for any livestock and pets they can accommodate. Some will be willing to accept only certain types of animals, such as dogs or cats. Others may have large fenced pastures or yards where they can take horses, sheep, or goats. Still others may have small backyards where they can only take chickens.

Those offering their places as refuges can do so for free or for a fee. It is between the parties to decide all financial issues and ensure there is a good fit.

We also invite those with animal trailers to offer their services on this website. Some people will need help moving their animals.

BIG ISLAND STILL WELCOMING VISITORS

Tourism officials are reminding travelers the lava flow likely will not impact their vacations.

Most of the island’s hotels and resorts located along the Kohala and Kona coasts – the opposite side of the island – and none have announced any changes to operations in response to the lava flow.

Ross Birch, Big Island Visitors Bureau executive director, said, “It’s in a very remote part of the island and people don’t need to change their plans.”

However, Birch said, those with plans to stay at bed-and-breakfast or vacation rental units in the near future should keep in contact with the owners for the latest updates.

Guests who may not be able to stay in those units are urged to contact the BIVB office so accommodations can be made.

“We can connect people and help make other arrangements,” he said. “There is no reason not to come visit the Big Island.”
