Vigorous Breakout Northeast of Pu`u `Ō`ō

Breakouts remained scattered northeast of Pu`u `Ō`ō, on Kīlauea's East Rift Zone. This breakout was one of many on the flow field today. The breakout was fairly vigorous at this time as geologists encountered it just moments after it started.

June 27th lava flow and steepest descent paths near Pāhoa, Kīlauea

This small-scale map shows Kīlauea's June2th lava flow boundaries on March 25, 2016, in relation to the eastern part of the Island of Hawai‘i. The area of the flow field on February 20 is shown in pink, while widening and advancement of the flow field as mapped on March 25 is shown in red. Pu‘u ‘Ō‘ō lava flows erupted prior to June 27, 2014, are shown in gray. The black

Kīlauea's eruption in Halema‘uma‘u reaches 8th anniv

Kīlauea Volcano's summit eruption began on March 19, 2008, and continues today. The lava lake is contained within the Overlook crater, which is set within the larger Halema‘uma‘u Crater. In this February 28, 2016, photo, the lava lake surface was just 30 m (100 ft) below the rim of the Overlook crater. Spattering is visible in the southeast portion of the lake. USGS photo

An Endangered Honeycreeper, the `Akikiki (Kaua`i Creeper), in Hawaii

Many species of Hawaiian honeycreepers have persisted into the 20th century because high elevation rain forests on the islands of Kaua’i, Maui, and Hawai’i are cool enough to limit transmission of introduced avian malaria (Plasmodium relictum). Malaria transmission is tied closely to the effects of temperature on development of malarial parasites within their mosquito

Footprints in Ash from 1790 Kilauea Volcano Eruption

Footprints made in muddy ash during Kilauea's 1790 eruption are reminders that people experienced the largest explosive eruption in Hawai‘i in 1,000 years. More than 80, and possibly several hundred, people were killed by the eruption soon after the footprints were made.

Thomas A. Jaggar founded the Hawaiian Volcano Observatory in 1912 and served as its Director until 1940.  Shown here in 1925, Jaggar is at work in HVO's first building, which, at the time, was located on the northeast rim of Kīlauea Volcano’s summit caldera, near the present-day Volcano House hotel.

Spattering at Small Pu`u `Ō`ō Vent

A small vent in Pu‘u ‘Ō‘ō crater throws spatter a short distance, building up a small cone around its opening. A thick layer of Pele's hair covers the downwind part of the cone. This vent was also the source of a small lava flow erupted on the crater floor in the past day.

Lava covers part of the Pu‘u ‘Ō‘ō crater floor

This movie, created from a sequence of HVO webcam images, shows lava erupting from a spatter cone within the south embayment in the Pu‘u ‘Ō‘ō crater (see February 24 image below for location). The activity started around 8:15 a.m., HST, on Wednesday, March 2, 2016, and covered part of the crater floor before ceasing at about 3:00 p.m. The lava did not flow beyond the

Energy from the sun supports most life on our planet, but far below the sea surface, another, less obvious energy source pumps heat and life-giving energy into the earth's biosphere. As a result, life persists independent of the sun's energy in some special seafloor environments.

Kīlauea's eruption is 24/7; it needs no sleep, takes no days off, and cares not if rain is falling in buckets. HVO's staff is not 24/7; it needs sleep, takes days off, and can't do much observing in heavy rain. How, then, does HVO watch the eruption?

Two weeks ago, scientists from around the world came together to discuss past and future research on an important, but little known, volcano. Long Valley Volcano, near the town of Mammoth Lakes, California, does not have the classic look of Mt. Fuji or the characteristic shield-shape of Kīlauea or Mauna Loa.

On November 29, 1975, the latest magnitude-7 earthquake in Hawai`i struck near Kalapana, causing a tsunami that killed two campers at Halape and resulting in $14 million (2003 dollars) in damage. It was the only magnitude-7 earthquake to hit the Big Island during the 20th century.

We're accustomed to seeing news stories about natural disasters around the world where either national or international aid agencies come to the rescue to aid victims. In Hawai'i, the County Civil Defense and Red Cross Agencies are activated in these situations.
