Changes at Halema`uma`u Over Time

This is a comparison of photos taken from the same location in the Volcano House on May 19 and June 13, 2018. The focal length of the lens for each photo is almost the same. The photos show the enlargement of Halema‘uma‘u laterally and vertically. Note how much lower the rim is relative to the tree in the lower photo.

[K2cam] Halemaʻumaʻu Overlook Vent from HVO Observation Tower

This image is from a research camera mounted in the observation tower at the Hawaiian Volcano Observatory. The camera is looking SSE towards the active vent in Halemaʻumaʻu, 1.9 km (1.2 miles) from the webcam. For scale, the crater wall of Halemaʻumaʻu behind the eruptive vent is about 85 m (~280 ft) high.

[HTcam] Halemaʻumaʻu Overlook Vent Thermal from Halemaʻumaʻu Overlook

This image is from a temporary thermal camera located on the south rim of Halemaʻumaʻu and looking steeply toward the north at the active Halemaʻumaʻu vent. The temperature scale is in degrees Celsius up to a maximum of 500 degrees (932 degrees Fahrenheit) for this camera model, and scales automatically based on the maximum and minimum temperatures within the frame.

The weekly newspaper series "Volcano Watch" has been published continuously since November 1991. Its articles keep Big Island residents informed about Kīlauea Volcano's ongoing eruption.

How much magma enters Kīlauea every day? How much is erupted to the surface? How much stays underground?

In our "Volcano Watch" series and in our scientific reports and presentations, we present and discuss findings relating to volcanoes and earthquakes.

Several million years ago, when Kaua`i was the youngest island in the Hawaiian archipelago, and Pele made her home in the caldera atop Mount Waialeale, a small flock of finches made landfall somewhere in the Hawaiian Islands, exhausted from their trans-Pacific journey. Perhaps they had been blown off-course by a hurricane.

We recently completed a leveling survey along the Ka`u trail in Hawai`i Volcanoes National Park. This 16-km (10 mi) route runs inland from the south coast of the Big Island, crosses the Great Crack, and reaches Highway 11 between Pahala and Kīlauea's summit.

A TV crew doing a documentary on lighthouses in Hawai`i recently asked HVO if erupting Kīlauea and Mauna Loa could have served as natural beacons for Polynesian wayfarers. Stromboli, a constantly active volcano in the Aeolian Islands north of Sicily, has been known for more than 2,000 years as the "lighthouse of the Mediterranean."

In recent weeks the U.S. Geological Survey's Hawaiian Volcano Observatory has begun a program to install new instrumentation to help monitor Mauna Loa Volcano. These new instruments, called volumetric strainmeters or dilatometers, will measure rock strain below the ground surface.

The Wailuku River is an important landmark to geologists, because it marks the approximate boundary between the lava flows of Mauna Kea and Mauna Loa.

An engineer for a local road-construction contractor recently called the U.S. Geological Survey's Hawaiian Volcano Observatory to report his company's disturbance of a bench mark. He realized the significance of this incident and properly reported it to the government agency that would be affected.

On May 1, 2000, President Clinton announced the United States' decision to stop degrading Global Positioning System (GPS) accuracy. The act has made it possible for civilians to obtain positions as precise as 15 meters (50 ft) using handheld portable GPS receivers. It benefits us in the volcano world, too.

Mauna Kea's peaceful appearance is misleading. The volcano is not dead. It erupted many times between 60,000 and 4,000 years ago, and some periods of quiet during that time apparently lasted longer than 4,000 years. Given that record, future eruptions seem almost certain.
