Channeled cascade on Paliuli

Channeled cascade on Paliuli. Other videos on this day focus on front of this cascade. Wind noise in this and other clips is obvious, but listen for sounds of pieces of crust scraping against one another or across ground. For scale, flow front in all clips is 1-1.5 m high.

PubTalk 12/2002 — Hawai`i's Volcanoes—Never a Dull Moment

20 Years of Eruption at Kilauea and Waiting for Mauna Loa

by Don Swanson,Volcanologist, Hawaiian Volcano Observatory

 

  • Kilauea's Pu'u O'o-Kupaianaha eruption, which began on January 3, 1983, is already the volcano's longest rift eruption in at least 600 years
  • Lava has destroyed 8 miles of highway and 189

Luckily, Hawai`i experiences volcanic ash much less often than it does lava flows. When it comes, though, it can be anything from a nuisance to a disaster for those beneath the falling ash. The most recent ash fall, from Halemaumau in 1924, was minor but affected residents from Maku`u to Pahala. The latest major ash fall, in 1790, resulted from explosions at the summit of Kilauea.

Big Island residents have long contended with the threat of tsunami. The central Pacific is, unfortunately, ground zero for many of the world's most destructive seismic sea waves.

On May 22, 1960, the largest earthquake ever recorded struck the coast of western Chile. The magnitude of this quake was so great that it literally went off the Richter scale; seismologists estimate the effective magnitude at about 9.5. The amount of fault slip during this quake and the area over which the slip occurred were both staggering.

The past two weeks have been exceptional for viewers of Kilauea's lava flows. Both colorful and convenient, the flows have drawn visitors to the island and attracted many residents as well. How did this happen?

Lava flows from the Pu`u `O`o vent on the east rift zone of Kilauea Volcano in Hawaii are entering the sea and are rapidly adding new land to the coast, according to the U.S. Geological Survey’s Hawaiian Volcano Observatory. The USGS Web site http://hvo.wr.usgs.gov/kilauea/update/ features near real time lava flow updates as well as photographs.

 Lava cascades down sea cliff and moves across bench

"The only constant is change" is an adage that certainly applies to Kīlauea Volcano. Over the past weeks volcano watchers have been treated to views of incandescent lava patches high above the coastal flats, spectacular streams of lava cascading down cliffs, lava-induced forest fires, and surface lava toes, lobes and rivulets edging toward the sea.

In early November 2000, the largest earthquake to strike the Big Island in more than a decade occurred, yet no one, not even seismologists, noticed it. This earthquake was not located a great distance offshore; indeed, part of the fault that slipped lies beneath the Chain of Craters Road where it approaches the currently active lava flow. So why was this quake not felt?

For years, scientists have tried to understand what causes earthquakes. They have recorded, catalogued, and analyzed them.

Hawaiian volcanoes are rich in excitement, beauty, and challenge, but they're not awash in mineral resources. How is it, then, that Kīlauea has a "golden pumice?"
