UPDATE: Wednesday, 6:45 pm

Although several cracks are producing spatter, the lava flow from column 17 has not progressed since Tuesday, according to Hawaii County Civil Defense authorities.

The Halemaumau crater spit out ashes. The airline says it drifts almost continuously into the southwest. Ashfall and vog have reported along Highway 11 to Pahala.

The Hawaii County Fire Department reports that air quality is conditional around cracks in the southeastern area of ​​Lanipuna Gardens and surrounding plots on Pohoiki Road. Condition Red means that there is an imminent threat to health and action is taken to limit further exposure.

Highway 130 is open only to residents outside Malama Street, according to the State Department of Transportation. However, no large trailers or heavy equipment is allowed over the metal plates.

Highway 132 is closed at the intersection with Pohoiki Road and a checkpoint is located on Highway 130 of Pahoa High School. Traffic beyond all roadblocks is restricted to local traffic.

The Volcano School of Arts and Sciences is closed today.

5 pm

The Hawaiian Kau District continues to receive an 8 o'clock ash advisory

However, the weather officials will reassess the report after sunrise and may need to extend it if the ashes continue ,

According to the National Weather Service, today's Hawaiian Island can expect winds from the northeast at 15 miles per hour

Despite earlier rumors of a potential tsunami related to volcanic activity, a Pacific tsunami is reported by the US Geological Survey The Hawaiian Volcanic Observatory is not possible due to the ongoing geological activity associated with Kilauea's outbreak.

Tuesday 19:20

The Civil Defense Agency in Hawaii responded tonight to a rumor about a possible tsunami.

The agency noted that "According to the Hawaiian Volcano Observatory There is no geological evidence of a tsunami-causing earthquake at this time, and such an event is highly unlikely."

Civil defense received media and public inquiries in which she was asked about the potential of a tsunami.

HVO, Pacific Tsunami Warning Center and other state and federal partners continue to monitor volcanic and seismic activity

18:40

The National Meteorological Service has issued the Ash Report recommendation for areas on the Big Island until 8am Extended on Wednesday as Halemaumau Crater continues to emit huge ash clouds at Kilauea Summit

Volcanic ash is expected to reach the southwestern region, including Wood Valley, Pahala, Punaluu, Naalehu and Hawaiian Oceanview Estates.

It is expected that ash accumulations will be deposited up to a quarter inch in the report (19659012). The Tradewinds are expected to weaken tonight by Wednesday and then breeze from Thursday to weekend, it said.

The weather service said the Advisory Ma They must be extended according to the conditions and warn that the ash may cause irritation of the eyes and the respiratory tract. Everyone in respiratory care consultancy should stay indoors to avoid inhaling the ash particles, and everyone outside should cover their mouth and nose with a mask or cloth, officials said.

Earlier this afternoon, the Hawaiian Volcano Observatory issued a "Communication for Aviation" warning pilots that the ash cloud from Halemaumau Crater at the top of Kilauea volcano was reported to be as high as 12,000 feet and conditions could be "explosive."

5:45 pm [19659010] The Volcano School of Arts and Sciences will close on Wednesday due to changes in wind direction volcanic ash from the Kilauea summit to the area.

The charter school in the city of Volcano is only a few miles from the summit crater.

School officials said a change in wind direction Wednesday "will likely result in dangerous driving conditions from ash rain … We expect to be open on Thursday as the wind direction is expected to return to the southwest and ash or (sulfur dioxide) from ours Campussen blows away. "

Kilaueas Halemaumau Crater today sent a large cloud of ash over parts of the Kau district in the southern area of ​​the Big Island today.

3:45 pm

The Hawai'i Electric Light Co. authorities warn that the volcanic ash that falls on parts of the southern Big Isle might expand

ash, which falls from elevated eruptions from the Halemaumau Crater to the top of Kilauea has led to warnings to the public and pilots. The National Weather Service has issued an ashfall recommendation by 6pm. Warns that volcanic ash will likely fall southwest of the summit, including Wood Valley, Pahala, Punaluu, Naalehu, and Hawaiian Oceanview Estates

"A combination of light dust deposits of ash and moisture on utility insulators could lead to electrical shorting that leads to power interruptions could, "said Helco spokeswoman Rhea Lee-Moku. "When this happens, we are ready to respond as soon as it is safe for the employees to work in the affected area." While we have equipment that can wash off ashes from utilities, this is the first experience we have with widespread volcanic ash

She said that extended power interruptions can occur when the ash rain covers a large area or is very heavy

During a power outage, the company recommends the following to its customers:

>> Disconnect sensitive electronic devices and other devices.

>> Keep refrigerators and freezers closed as much as possible. Dispose of perishable food that has been over 41 ° F for more than two hours.

>> People who need life support should first arrange with a hospital or emergency facility.

14:45

The State Department of Transportation has reopened Highway 130 in Lower Puna behind Malama Street for residents only.

The County Civil Defense of Hawaii says that no large trailers or heavy equipment should be taken over the metal plates were placed over cracks in the road caused by the volcanic activity.

The Hawaiian Volcano Observatory reports a steady eruption of ashes coming from Halemaumau Crater. Ash is reported via Highway 11 to Pahala.

14:15

The Hawaiian Volcano Observatory has issued a "Notice for Aviation" warning pilot that the ash cloud rises from the Halemaumau crater to the top of the Kilauea volcano has a height of up to 12,000 feet, and the Conditions could become more "explosive".

HVO has upgraded its air-raid alert to red by Orange.

The alarm says: "From this morning on, the ash outbreak From the viewpoint in the Halemaumau crater on the Kilauea volcano, the peak has generally increased in intensity, with the ashes rising almost continuously out of the vent and moving westward to the southwest Ashfall and vog (volcanic air pollution) has been reported in Pahala, about 18 miles downwind. (National Weather Service) Radar and pilot reports show that the top of the ash cloud is as high as 10,000 to 12,000 feet above sea level, however this can vary depending on the strength of the activity and wind conditions. "

HVO scientists warn that" at any time the activity may become more explosive, increasing the intensity of ash production and producing ballistic missiles near the trigger. "

They said that while the ash cloud is drifting southwest with the trade winds, it is expected that this will change over the next 24 hours, and other areas around the Kilauea peak are likely to receive an earthfall.

Ash has reportedly fallen in Pahala and the Kau Desert today.

PREVIOUS COVER [19659010] HILO >> The action on Kilauea Volcano today largely moved to the summit area as rockfalls and gas explosions ignited an impressive show at Halemaumau Crater and a gray cloud several thousand feet into sent in the sky that scattered ashes over roads in the village of Pahala.

Steve Brantley, deputy senior scientist at the US Geological Survey's Hawaiian Volcano Observatory, said the force of the ash clouds in the crater had "increased a bit" today. The ash emissions were almost continuous, "with intermittent, high-energy ash eruptions or flags," he said.

The trade winds from the northeast pushed most of the ash into the southwest. David Damby, a chemist and volcanologist at USGS, said the ashes are essentially "stone powder" and non-toxic.

"You just want to limit your exposure to it," he said, because it can cause eye, nose and throat irritation.

At 13:00 today, ash was reported along Highway 11 to Pahala.

About 30 miles away in the Lower East Rift Zone of the volcano, Fissur 18 created a lava flow that moved northeast, now about 1 1/2 miles long. However, in the past few hours, this rift has brought "very little" new lava into the stream, Brantley said.

"Testimonials show that the current has moved 1,200 feet the previous day, but it has not moved much that moment," he said.

According to the HVO, the only rift active this afternoon is Rift 17, which has slowed considerably and is moving towards the ocean at a speed of approximately 20 yards per hour. From 1:00 am, the lava flow was about 1.2 miles off Highway 137, and neither houses nor roads were threatened.

Scientists also observed a small new rift that opened just above Fissure 18 and released a small lava block called Brantley. Earthquake activity indicates that magma is still penetrating the area, he said.

"It has slowed down in the last few days, but it is still moving," although the earthquake situation suggests that the underground magma is not well advanced

Ormat Technologies Inc., the owners of Puna Geothermal Venture facility in the East Rift Zone, today issued a statement that the steepest topographic paths, which could be a lava-led route, lie around and away from the power plant towards the ocean.

"This gives the company confidence that the risk of superficial lava entering the facility is low," the statement says. The CEO of Ormat Technologies said the aboveground parts of the 38 – megawatt plant have not suffered any physical damage, but a full assessment will have to wait for the situation to stabilize.

"We continue to monitor the situation in coordination with (Hawaii Electric Light Co.) and local and state authorities, and we expect the Puna operations to be restored as soon as it is safe," Angel said in the statement.

Tom Travis, administrator of the Hawaii Emergency Management Agency, announced Monday that the state and county are developing a plan to kill three active geothermal sources at the PGV site by injecting them with cold water and iron plugs sealed.

This effort to kill wells could begin today, Travis said.

Because of the volcanic activity residents of the island of Hawaii and visitors are also referred to the following:

>> The State Department of Transportation said this afternoon that work on Highway 130 near Leilani Estates from Malama Street to the Kamaili Road was completed due to new cracks in the sidewalk that developed overnight. The road was reopened at 13.00. only for local traffic.

>> Highway 132 is closed at the Pohoiki Road intersection. A checkpoint is located on Highway 130 of Pahoa High School, only local traffic allowed.

>> The Department of Health reports that dangerous emissions of sulfur dioxide from fissures are particularly dangerous for the elderly, children, babies and people with respiratory problems. SO2 can be carried by the wind or cover an area without wind.

>> HVO scientists say that the eruptive activity in the Lower Puna has remained concentrated in the Fissure 17, with scattered lava present in the Fissure 18 injects. A new column, # 20, near Column 18, also created two small lava pits, it was said in the early afternoon. The lava flow from Fissur 17 has been at around 1,250 feet since 2:30 pm. Monday. The propulsion has slowed significantly, according to HVO since Monday afternoon. Volcanic gas emissions remain elevated in the entire region before the fissures, warns HVO. Scientists said that magma continues to be delivered to the lower East Rift Zone, continuing increased earthquake activity.

>> The State Department of Transportation planned to re-open Highway 130 from Malama Street to Kamaili Road afternoon after an inspection earlier today showed the carriageway is safe. However, the highway can be closed again when dangerous conditions develop.

>> Air quality in Pahala this morning was reported as "unhealthy" and is declining, according to the Vog Measurement and Prediction Project of the University of Hawaii. "Avoid excessive exposure to ash, which is an eye and airway irritation," said the weather service on alert. "People with airway sensitivities should take extra precautions to minimize exposure."
