Continued movement of lava across rope barrier

Continued movement of lava across rope barrier. Muffled sounds of a long-lasting, migrating methane explosion can be heard about two-thirds of the way through the clip, followed by a "Wow."

March 6, 2003

Lava burning bush

Lava moving down rather steep slope and burning bush at snout of stream. Width of burning bush, about 1 m.

Lava moving rapidly

Toe of lava moving fairly rapidly down moderate slope along edge of Kohola flow. Note that lava moves more rapidly at top than at base of toe, in contrast to lava in video for March 1, which was moving across nearly flat ground. Note also developing wrinkles in moving crust.

Lava flow advancing

Details of flow advance shown in 25-second clip. Lava oozes outward from base of flow, picks up loose flakes of crust (1-3 cm across) on ground surface, and lifts them up as flow thickens. This is how material once on ground surface gets onto top of flow. This is a common mode of advance of lava on nearly flat slope. Note: This is a large file because of its

Cascade and lava falls on west edge of Kohola ocean entry

Cascade and lava falls on west edge of Kohola ocean entry, falling over sea cliff about 8 m high. Turn down your sound; lots of wind noise.

February 18, 2003

Broad cascade and falls

Part of broad cascade and falls that suddenly gushed from under crust at top of sea cliff. Turn down your sound; lots of wind noise.

Lava Cascade

Base of lava cascade and construction of mound on beach below sea cliff. Turn down your sound; lots of wind noise.

February 13, 2003

Front of flow advancing

Front of flow advancing rather quickly across grassland about 70 m from Chain of Craters Road. Grass ignites a short distance ahead of the lava, owing to the intense radiant heat. Width of scene, about 4 m.

February 13, 2003

Video of lava flows

Same flow as in upper video, but a little farther upstream. Grass burns along the side of the stream. Width of view, 4-5 m.

January 17, 2003

Rushing toe of lava

Rushing toe of lava that has just broken out from front of one active lobe of flow on coastal flat seaward of Paliuli. Toe is about 50 cm wide. Note how crust is "scrunched" at bottom of minicascade, resulting in wrinkles. Other videos on this day show breakouts in same area. In all videos, wind noise may be bothersome.

January 17, 2003

Small gush of lava

Small gush is on crest of small divide and starts flowing down right side as well as left. Stream is about 1 m wide.

January 17, 2003

Lava tear

Tear begins to develop in crust on stage-left side of flow. Lava eventually pours from tear. Stream is 0.75-1 m wide.

As we all know, there are no facts about the future. We cannot know for sure what will happen tomorrow, much less next year or 1,000 years from now. How, then, can we be so bold as to guess where the next volcano will form in Hawai`i, perhaps 100,000 years or more down the road?

While watching the Olympics a few weeks ago, I started wondering how our lava flows would place in typical competitions. Of course, it wouldn't be quite as simple as setting up a course, getting an eruption to happen at a convenient time at the starting point, and accurately timing the result.

Sharing the results of scientific investigations on Hawai`i's volcanoes has always been a primary goal of scientists working at the Hawaiian Volcano Observatory. In 1912, Thomas A. Jaggar, Director of HVO, published the first series of informal newsletters about the activity of Kīlauea and Mauna Loa.

East Rift Zone Eruption Quietly Delivers Lava to the Sea

March 12, 1998

Two geologists who used to work at the Hawaiian Volcano Observatory were back in the state last week viewing Hawai`i's volcanoes from a different perspective. Cruising among the islands aboard a 270-ft ship, Jennifer Reynolds and Dave Clague (HVO's former scientist-in-charge) thoroughly enjoyed the smooth water and sunny weather.

In recent months we have discussed hazards from lava flows in the Hilo and Puna areas. Today we focus on the Ka`u District.

Someone once said, "Climate is what you expect, weather is what you get." The weather of the last week or so has brought a sigh of relief to many east Hawaii residents. The return of the trades has brought much needed moisture, creating the joyful sound of water trickling into depleted water tanks and easing fire danger that had reached critical levels.

Bench collapse, temporary draining of lava tube are prominent events of the past three weeks

A gentle, effusive style of activity has characterized the ongoing eruption of Kīlauea for well over a decade now. But remember the explosive episodes of 1983, `84, `85 and the first half of `86? Pu`u `O`o burst forth periodically with towering lava fountains that could be seen for miles around. Ever wonder why the change? Just what causes a volcano to flow rather than blow?

Japan—only 63 million years away! Advertising like that would put a shipping company out of business, but the Plate Tectonic Express has no competitors when it comes to moving continents and oceanic plates around the globe.

Scientific concepts are often thought to result from thinking about hard facts. Speculation is sometimes considered out of bounds for scientists.
