These views of Mauna Loa are from near the Hawaiian Volcano Observatory looking toward the west. The view on left is typical during strong trade winds that blow the plume from Halema‘uma‘u Crater southwest of the summit area. The view on right is common during slack winds that allow vog conditions to develop in the summit area of Kīlauea. During such conditions, people

[KIcam] Kīlauea Caldera 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, Halemaʻumaʻu is approximately 1 km (0.6 mi) across and about 85 m (~280 ft) deep.

[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.

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.

For the past two weeks, numerous reports of increased seismic activity heralding a possible large eruption at Popocatepetl Volcano in Mexico have been in the news. A disturbing commentary in the reports was that residents living on the slopes of the volcano were hesitant to comply with the government's order to evacuate.

It's been 60 years since Harold Stearns first recognized that Hawaiian island volcanoes evolve through stages we call shield, postshield, and rejuvenated volcanism.

Two months ago, we discussed early findings suggesting that Kīlauea had an explosive eruption far larger than we dared think. The study has progressed since then, and the early findings have been confirmed and extended.

Last week we wrote about the large Kalapana earthquake of 1975. In the article we discussed the importance of repeated geodetic observations that monitored the accumulation of strain before the earthquake and allowed HVO researchers to forecast the event.

Wednesday, November 29, 2000, will mark the 25th anniversary of the magnitude 7.2 Kalapana earthquake that struck the Puna and Ka'u districts of Hawai'i County. The 1975 earthquake is the second largest ever documented in Hawai'i, overshadowed only by the 1868 great Ka'u earthquake, which has been estimated to be of magnitude 7.9.

The Kalij Pheasant is an unparalleled success among game birds introduced in the 50th State. Because Hawai`i has no native upland game birds, people have imported a total of twelve species of pheasants, quail, partridges, peafowl, and wild turkeys from all over the world. Last to arrive was the Kalij, released in 1962 at Pu`u Wa`awa`a Ranch.

Anyone who has been close to an active flow or steam vent knows that the heat coming from one of these features is intense and, at times, overwhelming! It will come as no surprise, then, that thermal monitoring of volcanoes and their products plays an important part in volcanology.

Kīlauea has been erupting for nearly 18 years, and there is no sign of it stopping anytime soon. But all previous Kīlauea eruptions ended, and there's no reason to think this one is any different. What can we expect when the curtain finally falls?

To many of us, Hawaiian volcanoes loom sleepily overhead, occasionally stirring from their slumber and oozing lava flows down their flanks toward the sea. Deep within the towering volcanoes, however, lies the potential for powerful explosions of volcanic ash and blocks.

Driving along the Queen Ka`ahumanu highway from Kailua-Kona to Waikoloa, one passes a vast expanse of well-exposed lava rock. These flows are from Hualālai and Mauna Loa Volcanoes and are of various ages. If you slow down and look carefully, you are able to recognize individual flows by their distinctive surface texture, color, or luster.

Sweeping vistas into Haleakalā Crater are seen in the final stretch of road at Haleakalā National Park, from the summit visitor center to the top of Red Hill. Some observers, however, focus their attention on the pavement, which is prominently cracked perpendicular to travel direction.

Earthquakes occur every day on the Island of Hawai`i. Most are small, less than magnitude 3, but typically a couple are felt by someone each week. Damaging earthquakes occur every few years, and very large ones take place every few decades or more often.
