Hawaiian Volcano Observatory Update – Kahaualeʻa Flow Front Stalls, New Overflow in Puʻu ʻŌʻō

Breakouts have diminished over the past few days on the Kahaualeʻa flow (heading northeast of Puʻu ʻŌʻō), and the flow front has not advanced significantly since April 8.

Compare Saturday’s thermal image with that from the April 8 overflight.

During Saturday’s flight, there were no active breakouts at the flow front.

Breakouts have diminished over the past few days on the Kahaualeʻa flow (heading northeast of Puʻu ʻŌʻō), and the flow front has not advanced significantly since April 8. Compare today’s thermal image with that from the April 8 overflight. During Saturday’s flight, there were no active breakouts at the flow front.

A vigorous flow was erupted on the floor of Puʻu ʻŌʻō crater starting early this morning from a cone near the north rim, but a smaller flow was also erupted from a spatter cone near the south rim around noon. This photo captures a burst of spatter from the southern cone as the small flow was erupted.

Lava Flow 2

Lava erupted this morning from the cone near the north rim of Puʻu ʻŌʻō crater, with a small portion of the flow emptying out onto the east spillway. This new flow brings the floor of the crater slightly closer to the north crater rim.

The Latest Hawaiian Volcano Observatory Update

The latest update from the Hawaiian Volcano Observatory:

This photo looks northeast and shows Puʻu ʻŌʻō crater. Recent activity has been focused around a few spatter cones on the crater floor.

HVO1

At the far edge of the crater, a small lava pond has been active and has been the source of flows extending northeast of Puʻu ʻŌʻō. Those flows are visible at the top-center of the photo. Just below the horizon two small sources of smoke mark where the flow front is burning lichen and moss covering older ʻaʻā flows.

A closer look at the flow extending northeast of Puʻu ʻŌʻō. Puʻu ʻŌʻō cone is at the right edge of the photo, and view is towards the northeast.

hvo2

In the foreground, two sources of fume mark the path of the lava tube supplying lava to the flow front. In the top-left, a few sources of smoke mark where the flow margin is burning moss and lichen on older flows. Today, the flow front was just over 4 km (2.5 miles) from the vent on Puʻu ʻŌʻō.

South winds permitted clear views into the south portion of the Overlook crater, which is often obscured by thick fume.

HVO3

The bright orange area is the location where lava at the surface of the lake sinks back into the system, with spattering and degassing common in this area. A broad ledge of recently deposited lava occupies much of the south portion of the crater.

Spattering is common in the area where lava sinks back into the system, and this photo shows these processes are occurring in a small grotto.

hvo4

In the right portion of the photo, the ledge occupying much of the south part of the Overlook crater is visible. Parallel lines along the front face of this ledge might appear at first glance to be layering within the ledge, but are actually thin deposits of lava that mark recent levels of the lava lake, much like bathtub rings.

 

This Week’s Hawaii Volcano Observatory Report

This Week’s Hawaii Volcano Observatory Report, for February 25, 2013:

Lava lake in Halemaʻumaʻu Overlook pit

Lava Lake 1

The lava lake in Halemaʻumaʻu remains poised at a relatively high level within the Overlook pit. The lake level dropped over the weekend. Though rising again now, it has not yet reached last week’s level.

Recently emplaced flows on Puʻu ʻŌʻō’s spillway

Top:  The “spillway”—Puʻu ʻŌʻō’s eastern flank—has been buried by flows fed mostly from a spatter cone on the northeastern side of the crater floor. Most of the dark-colored lava in the foreground is new lava that has resurfaced the spillway. The fume to the left is the trace of the Peace Day tube, newly covered by crater overflows, currently carrying lava to the coast. The tube carrying lava to the northeast is not obvious, but extends toward the lower right side of the photo. Bottom: Some of the recent overflows at Puʻu ʻŌʻō traveled to the southeast. This photo shows those overflows, which comprise several dark-colored channelized flows.

Spatter cone on northwest side of Puʻu ʻŌʻō’s crater floor

Top: There are currently four spatter cones on the floor of the Puʻu ʻŌʻō crater that have been the source of lava flows over the past several months. The one shown here is on the northwest side of the crater floor, close to the multiframe webcam shown on our website. The webcam, and an HVO geologist standing next to it, give a sense of scale for the spatter cone. The camera to the right of the person is the thermal camera on Puʻu ʻŌʻō shown on our website. Bottom: This is a closer look at the spatter cone on the northwest side of Puʻu ʻŌʻō’s crater floor. The photo was taken from near the site of the webcam on the north rim of Puʻu ʻŌʻō.

Spatter cone on northeast side of Puʻu ʻŌʻō’s crater floor

Top: This is another of the spatter cones on the floor of Puʻu ʻŌʻō. This one, on the northeast side of the crater floor, has long had an open top with a view of a small lava lake. Most of the overflows from Puʻu ʻŌʻō in the last few weeks have been fed from this spatter cone, successively piling up until the top of the spatter cone is now about level with the webcam on the north rim of Puʻu ʻŌʻō.  Bottom: This is a steep aerial view of the small lava pond at the top of the spatter cone on the northeastern side of the crater floor. Lava in the pond flows directly into a lava tube which is supplying the active flow northeast of Puʻu ʻŌʻō. The head of the tube, marked by fume, extends from the pond toward the left side of the photo.

Views of the Kahaualeʻa flow, northeast of Puʻu ʻŌʻō

Top: The flow traveling north from Puʻu ʻŌʻō, which we are informally calling the Kahaualeʻa flow, abuts the edge of episode 58 flows erupted during 2007–2008. The flow has also partially surrounded one of the few vestiges of greenery within the flow field—the forested top of the old Kahaualeʻa cone. Bottom: This is a view of the front of the Kahaualeʻa flow looking back toward Puʻu ʻŌʻō, where the flow originates.

Ocean entry near Kupapaʻu Point

Lava continues to enter the ocean near Kupapaʻu Point, with an entry point just inside the National Park (near left side of photo) and entry points just east of the Park boundary (near the center of the photo). Widely scattered patches of surface lava are also active inland from the ocean entry points. Puʻu ʻŌʻō is a low lump on the horizon near the top of the photo immediately to the right of the image’s center line. The plume from the lava lake in Halemaʻumaʻu is visible in the background to the left of the image’s center line.

Satellite Image Shows Active Lava Breakouts on Flow Field

This image was captured on Wednesday, February 13, by the Advanced Land Imager sensor aboard NASA’s Earth Observing 1 satellite.

Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures, and show active or very recently active lava flows. The image shows three general areas of active breakouts.

  • First, flows have been active for several weeks northeast of Puʻu ʻŌʻō, and have reached about 2 km (1.2 miles) from the Puʻu ʻŌʻō crater rim.
  • Second, breakouts have been active above the pali, about 5 km (3.1 miles) southeast of Puʻu ʻŌʻō.
  • Third, several scattered breakouts have been active on the coastal plain, with several patches very close to the shoreline above the active ocean entry. Satellite images such as this help fill in observational gaps between field visits.

Kilauea Volcano’s East Rift Zone Eruption: 29 Years and Counting

Jan. 3, 2012 marks the 29th anniversary of Kīlauea’s ongoing east rift zone eruption. This eruption, particularly events that occurred during the past year, will be the topic of an “After Dark in the Park” program in Hawai‘i Volcanoes National Park, Tues., Jan. 3.

On Mar. 6, 2011, a spectacular fissure eruption between Pu‘u ‘Ō‘ō and Nāpau Crater on Kīlauea’s east rift zone produced lava flows that poured into a pre-existing ground crack and advanced through an ‘ōhi‘a forest. For scale, USGS Hawaiian Volcano Observatory scientists (lower right) can be seen walking toward the flow. USGS photo by Tim Orr

Tim Orr, a geologist with the U.S. Geological Survey’s Hawaiian Volcano Observatory, will review the eruption, focusing on highlights from Kīlauea’s 2011 activity. The program begins at 7 p.m. at the park’s Kīlauea Visitor Center Auditorium. Park entrance fees apply.

The eruption began just after midnight on Jan. 3, 1983, with lava erupting to the surface along several fissures.  By June 1983, the eruption was focused at a single vent. Over the next three years, lava fountains up to 1,500 feet high roared from the vent 44 times, building a cinder-and-spatter cone named Pu‘u ‘Ō‘ō.

In July 1986, the eruption shifted to Kupaianaha, a new vent farther down the east rift zone. Lava poured from this vent nearly continuously for almost six years, burning and burying Kīlauea’s south flank, including the communities of Kapa‘ahu and Kalapana, in 1986 and 1990, respectively.

Early in 1992, the eruption returned to vents on the flanks of Pu‘u ‘Ō‘ō. Over the next 18 years, lava flowed down the slopes of Kīlauea, inundating areas within and outside of Hawai‘i Volcanoes National park and often reaching the sea.

During the past year, Kīlauea’s ongoing east rift zone eruption has included two spectacular fissure eruptions, a dramatic outbreak of lava from the west flank of Pu‘u ‘Ō‘ō, and, on Dec. 9, 2011, a new ocean entry USGS scientists named West Ka‘ili‘ili—the first ocean entry within the boundaries of Hawai‘i Volcanoes National Park since 2009.

Since the eruption began in 1983, lava flows have buried 48 square miles of public and private land, destroying vast tracts of native forest, nine miles of highway, and 213 structures, including homes, a church, and the Waha‘ula Visitor Center in the park.

While Kīlauea’s current east rift zone eruption has been its most destructive event in recent history, the eruption has also been constructive. Molten lava flowing into the sea has added about 500 acres of
new land to Hawai‘i Island.

Relocated this webcam to the HVO building to view the activity within Halema’uma’u crater. The new vent is 1.9 km (1.2 miles) SSE from the webcam. For scale, Halema’uma’u crater is approximately 100 m (330 ft) deep. DISCLAIMER: This panorama is a composite of three images from a temporary research camera positioned in the observation tower at the Hawaiian Volcano Observatory. At times, clouds and rain obscure visibility. The camera is subject to sporadic breakdown, and may not be repaired immediately. The camera is observing an area that is off- limits to the general public because of significant volcanic hazards.

Chain of Craters Road Reopened After Eruptive Activity

Media Release:

Officials at Hawai‘i Volcanoes National Park reopened Chain of Craters Road at 4 p.m. today, after a 24-hour closure resulting from new eruptive activity at Kīlauea volcano’s Pu‘u ‘Ō‘ō crater. Park rangers are stationed near sea level at the bottom of Chain of Craters Road, at Pu‘u Huluhulu and at Jaggar Museum to inform visitors of the latest conditions and best viewing opportunities.

On Wed., Aug. 3, the crater floor and lava lake within Pu‘u ‘Ō‘ō collapsed and lava flowed out of its west flank. Scientists at the USGS Hawaiian Volcano Observatory monitored a rapid deflation of the crater floor and lava lake, and by 3:15 p.m. yesterday, the collapse began.

Visitors to Hawai‘i Volcanoes National Park are able to view dramatic glows from the new Pu‘u ‘Ō‘ō eruption from several vantage points within the park, including Pu‘u Huluhulu, the Jaggar Museum overlook, and from the bottom of Chain of Craters Road.

“For the more adventurous, a short mile-and-a-half round-trip hike to Pu‘u Huluhulu puts you in the line of site of the vent and new lava flows off the west flank of Pu‘u ‘Ō‘ō,” said Chief Ranger Talmadge Magno. “And, weather permitting, the glow is apparent after sunset as the daylight obscures any redness. Visitors can also drive to the end of Chain of Craters Road and look up and see the glow,” he said.

Chief of Interpretation Jim Gale posted video to the park’s website: http://www.nps.gov/havo/photosmultimedia/eruption-20110803.htm.

In addition, Kīlauea’s summit eruption at Halema‘uma‘u crater continues, and visitors can often hear the roar from rocks exploding off crater walls, and can observe a beautiful red glow after nightfall. Rangers reported that the new incandescence from Pu‘u ‘Ō‘ō is also visible from the Jaggar Museum overlook.

Hawai‘i Volcanoes National Park is open 24 hours a day, conditions permitting. For eruption updates, call (808) 985-6000.

And while visitors are enjoying new lava activity, a six-person fire crew has contained approximately 80 percent of a wildfire ignited by lava on the southern end of the flow, approximately one acre in size. Another fire on the north end of the flow continues to burn, and is being monitored by fire officials.

Mainland Media Folks Experience Rare Occurrence at the Volcano

For the next few days a group of mainland journalists and bloggers are having the opportunity to do a few FREE or cheap things on the Big Island.

Today started off with a scavenger hunt at the Hilo’s Farmer’s Market where each of them were given $10.00 and were sent off to find food for lunch for everyone to make a picnic out of.

The highlight of today was being able to see the volcano here on the Big Island from both the top where the Halema’uma’u Crater is… to the bottom of the flow in Kalapana.

What they didn’t know was that they were going to be treated to a rare occurrence where the entire floor of Pu’u O’o collapsed into the crater.  Andrew Cooper, author  of the blog A Darker View,  wrote in his post today “Kilauea is up to Something“:

This afternoon the entire floor of Pu’u O’o has collapsed into incadescent rubble. For the last few months the crater at Pu’u O’o has hosted a lava floor that occasionally floods. This had formed a solid crust hundreds of meters across with spatter cones and small fresh lava flows across the floor. This has now completely collapsed. At the same time the rift has experienced a large number of small, mostly magnitude 2 earthquakes. At he same time there was rapid deflation at the summit caldera and at Pu’u O’o. Where has the lava gone?…

Well when I talked to Jessica Ferracane of Irondog Communications, she stated that the folks did in fact hear something happening at the time and it was quite spectacular!  Ferracane posted on her facebook account the following account:

Is listening to Halemaumau Crater boom and gasp as rocks fall into Pele’s home.  Amazing!

I met up with the mainland media folks in Pahoa and then we cruised down to Kalapana to see what was going on down there.

They were fortunate in that they got to go to a house down there on the lava flow and were treated to a spectacular view of the flow from there while remaining in a safe atmosphere.

As the sun went down… we could begin to see the orange glow of the lava making it’s way down the hillside.

Once the sun was completely down… you could see a nice flow from the top of the mountain down to the bottom of the hill.

It was a great day and evening for the mainland folks and they were treated to the award winning Kaleo’s Restaurant in Pahoa for dinner.

The media folks will be heading over to the other side of the island in the next few days to see some of the cheap and free things to do on that side of the island… it was great to meet them and I look forward to reading their media write ups on the Big Island when they return home.

Media Release:

Pu‘u ‘O‘o crater floor collapse followed by middle east rift zone eruption

USGS Image of Pu'u 'O'o Floor Collapse

At 1:42 p.m. HST this afternoon, USGS Hawaiian Volcano Observatory (HVO) monitoring network detected the onset of rapid deflation at Pu‘u ‘O‘o and increased tremor along Kilauea Volcano’s middle east rift zone.  At 2:00 p.m., Kilauea’s summit also began to deflate.

Between 2:16 and 2:21 p.m., the floor of the Pu‘u ‘O‘o crater began to collapse, and within 10 minutes, incandescent ring fractures opened on the crater floor a few tens of meters away from the crater wall. As the floor continued to drop, lava appeared in the center of the crater floor, the northeast spatter cone within Pu‘u ‘O‘o collapsed, and an obvious scarp developed on the west side of the crater floor, with lava cascading over the scarp toward the center of the crater.

At 2:41 p.m., the scarp on the west side of the crater floor appeared to disintegrate, exposing incandescent rubble.  Five minutes later, the collapse of a large block along the east crater wall produced a dust plume.

Webcam images showed that the Pu‘u ‘O‘o crater floor continued to drop through 4:26 p.m., when fume obscured the camera view.  HVO Webcam images can be accessed at http://volcanoes.usgs.gov/hvo/cams/.

Coincident with the collapse in Pu‘u ‘O‘o, an earthquake swarm began along Kilauea’s middle east rift zone in the area of Maka`opuhi and Napau Craters.  Tiltmeters showed east rift zone deflation, which continues as of this writing.

At 5:15 p.m., an HVO geologist flying over Kilauea’s middle east zone reported “an eruption in Napau Crater.”  The eruption is now known to be located between Napau Crater and Pu‘u ‘O‘o.

Updates on the status of this eruption will be posted on HVO’s Web site at http://volcanoes.usgs.gov/hvo/activity/kilaueastatus.php.

According to Jim Kauahikaua, HVO’s Scientist-in-Charge, “This event is remarkably similar to a 1997 eruption in and near Napau Crater, which lasted less than 24 hours.”

Kilauea’s summit also continues to deflate, and the lava lake level within the Halema‘uma‘u Crater vent continues to drop, facilitating rockfalls from the vent wall.

In response to the current volcanic conditions, Hawai‘i Volcanoes National Park has closed the Chain of Craters Road and all east rift zone and coastal trails, along with the Kulanaokuaiki campground, until further notice.

Daily updates about Kilauea’s ongoing eruptions, recent images and videos of summit and east rift zone volcanic activity, and data about recent earthquakes are posted on the HVO Web site at http://hvo.wr.usgs.gov.
