Magma pressures up under Kilauea ~ Ocean entry lava remains strong

The photo above, taken this morning and contributed to the blog by Ron Boyle, shows pahoehoe advancing across a small blacksand beach on the shoreline directly south of the old county viewing area. Lava continues building new benches for a quarter-mile section of this coastline.

Below are two photos I took May 2, 2010 of that original Waikupanaha County viewing area with the new entry plume beyond. For those of you that were out there when that lava ocean entry was active, you may notice how all the land in front and to the sides of the viewing area is now level with new lava. You can see the marked walking path tape is still there too.

The same little security hale is still intact


USGS deformation – inflation/deflation graphs are charting inflation now. This could translate into a more aggressive action down the Pulama Pali, surface flows and coastal entries. It is also causing the Halema’uma’u crater to glow very brightly after dark—check it out!

Below is a reposting of the general overview of conditions on the coast since little has changed in three days:
Halema’uma’u Crater still glowing brightly ~ Lava flows hot from mountain to sea


US Geological Service (USGS) at Hawaii Volcanoes National Park Observatory (HVO) has posted this excellent aerial photo over crater (above) on their images page. On that page they also have photos and captions about the Pu`u O`o crater cam they lost when a piece of the crater sloughed off a few days ago.

The aerial photo is from the April 28th, 2010 USGS image site, and surface lava has advanced further in many areas since, as indicated on my drawings and notes.


Halema’uma’u crater as seen after dark from the balcony of the Jaggar Museum

Active lava viewing prospects:
1) The Halema’uma’u crater has been degassing sulfur dioxide fumes by day and glowing strongly at times after dark from lava deep within the craters pit vent. Great views are from the Jaggar Museum within the Hawaii Volcanoes National Park, and the park is open to the public 24 hours a day.

2) Coastal viewing:
Highway 130 at Kalapana Gardens area -- Between the hours of 2:00 PM and 8:00 PM - park and walk one mile to the end of newly lava covered (May 5th) road; viewing is allowed until about 9:00 PM. Along the walk out and back the steam plume from the distant ocean entry lava can be seen and after dark it glows orange-red; long lines of degassing lava fumes coming down the hillsides by day –distant red lava orbs lined-up by night; at roads end the still-warm lava on the road can be felt and is still radiating hotter close by but beyond public access; occasional yellow flare-ups are witnessed in the distance as lava torches trees and vegetation further into the active flow field. Offered at the parking area only: security personnel, vendors, water and port-o-potties available; at roads end there are barricades, port-o-potties and security personnel.

Further information, links and warnings:
Active pahoehoe breakouts continue along with swelling of the hot flow fields at many locations of the April-May surface flow. The coastal entry points are still emptying a lot of lava into the sea as new deltas area being rapidly built. The entire length of the ocean entry and all land adjacent to it inland is quickly becoming unstable and should be kept well aware of from now on:
HAZARD ALERT: The lava delta and adjacent areas both inland and out to sea are some of the most hazardous areas on the flow field. Frequent delta/bench collapses give little warning, can produce hot rock falls out to 400 m (quarter mile) inland and in the adjacent ocean, and can produce large local waves and scalding water. The steam plume produced by lava entering the ocean contains fine lava fragments and an assortment of acid droplets that can be harmful to your health. The rapidly changing conditions near the ocean entry have been responsible for many injuries and a few deaths.

No significant changes; Kilauea volcano has active lava from crater to sea

Last night the crescent moon hung with Venus in the evening sky as seen from highway 130 where visitors walk to the viewing area.

Fact sheet:
Hawaiian Meaning
The Hawaiian name "Kīlauea" means "spewing" or "much spreading," apparently in reference to the lava flows that it erupts.
Most Recent Eruption
Continuous since January 3, 1983
Number of Historical Eruptions
61, not counting the continuous lava-lake activity in Halema`uma`u crater
Summit Caldera
The caldera itself has no Hawaiian name other than Kīlauea but houses the famous crater, Halema`uma`u; "hale" is a house, "ma`uma`u" a type of fern. Kamapua`a, a jilted suitor of Pele, is said to have built a house of ferns over Halema`uma`u to keep Pele from escaping her home and causing eruptions. The ploy failed.
· Dimension: 6 x 6 km (outermost faults), 3 x 5 km (main depression)
· Depth: 165 m deep
· Age: probably several incremental collapses 500-210 years ago
Oldest Dated Rocks
23,000 years old
Estimated Age of Earliest Subaerial Eruptions
50,000-100,000 years
Estimated Age of First Eruption of Kīlauea
300,000-600,000 years before present
Hawaiian Volcano Stage
Shield-forming stage

And a new USGS image page has this good aerial of the lava off the (new) end of highway 130:(Where highway ends is the location of the present viewing area)

Below are previous posts, which remain relevant as far as the overall lava activity picture.
(Click on any image for a larger view size in new window)

Lava continues well supplied from the eruption site near Pu`u O`o crater down the Pulama Pali; spreading out with active branches across the coastal flats and into the ocean in several locations along a quarter-mile of shoreline very near the old Waikupanaha entry point.

On the coast, pahoehoe continues actively flowing directly adjacent to the older Waikupanaha public viewing site; within 10-feet on the west & south sides and is now nearly level with that old viewing site. Much of the trail leading to this site is now covered in new & still hot lava.

Active lava breakouts are reportedly continuing very close by, but not onto, the paved end of highway 130. I do not know if visitors walking out to the latest public viewing location near the end of 130 were able to witness active lava there last night, or if they will see any tonight.

The Pulama Pali continues hosting some active advancement of new surface lava comprising of both A`a and pahoehoe. This latest flow may have burned into the April lava tubes and re-energized them.

Roads-end ‘viewing area’ extended closer to newly cooling lava ~ Active lava about the same

(Click on the image for a larger size in a new window)

As previously reported: active pahoehoe breakouts continue along with swelling of the hot flow fields at many locations of the April-May surface flow. The coastal entry points have changed somewhat in the past 48-hours, but are still emptying a lot of lava into the sea as new deltas area being rapidly built. The entire length of the ocean entry and all land adjacent to it inland is quickly becoming unstable and should be kept well aware of from now on.

Visitors that walked the mile from the Hawaii County roadside parking lot to the end of highway 130 designated lava viewing site last night reported seeing the most activity from the road itself, rather then the designated viewing area set up at the lava-covered terminus of 130. While walking the road they report seeing a distant steam plume where lava pours into the sea, which sometimes glowed orange-red after dark; an occasional flame-up of distant trees burning from lava, as well as some lava glows on the distant pali, again, after dark. There was no active lava visible from the designated ‘viewing area’ that I am aware of. But just beyond the new end-of-the-road viewing area lava is still breaking out in places.
