Slope map of Mauna Loa, including lava flows erupted since 1823 (gray), showing the approximate number of hours or days it took for a flow to advance from the vent location to the ocean or maximum reach of a flow. One flow that moved down the steep slopes on west flank of Mauna Loa reached the ocean in as little as 3 hours after the vent started erupting in 1950. The bold

[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.

This image is from a temporary thermal camera located on the north rim of Mauna Loa's summit caldera. 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 on the caldera floor and not the whole frame, which sometimes results in the

[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.

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

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 eruption on Kīlauea's East Rift Zone continues with little change. The episode 51 and 53 vents on the southwest flank of the Pu`u `O`o cone continue to feed lava directly into a tube system that transports the lava to Palama Pali and beyond, to the ocean entries at Kamoamoa.

A magnitude 3.0 earthquake was widely felt in the Hilo area on Thursday afternoon at 1:45 p.m. The earthquake was about 25 miles deep and was located offshore about 10 miles east of Hilo.

Volcanoes around the world emit a variety of gases in different proportions, with the main components invariably being carbon dioxide, water, and sulfur dioxide. Minor components include, but are not limited to, hydrogen gas, carbon monoxide, hydrochloric acid, hydrofluoric acid, methane, and hydrogen sulfide.

May 18 marks the anniversary of the 1980 eruption of Mount St. Helens that laid waste to over 200 square miles of forest and killed 57 people, as well as thousands of wild animals and birds.

Kīlauea is famous for eruptions of the type we are now experiencing - quiet effusion of lava that makes the eruption approachable. However, not all of Kīlauea's eruptions have been so passive and approachable.

May 7, 1993

The 10-year-long eruption along Kīlauea's East Rift Zone continues with little change. Active flows travel underground to the ocean in lava tubes from the eruptive vents on the south and west sides of the Pu`u `O`o cone.

The episode 51 vents on the west flank of Pu`u `O`o were active from April 23 at about 11:00 a.m. until April 28 at 11:30 a.m., when the eruption stopped once again. Since then, the lava lake inside Pu`u `O`o vent has risen from about 140 to between 120 and 130 feet below the rim of the crater.

The 10-year-long eruption on Kīlauea's East Rift Zone continues with little change. During the week, the lavaentries into the ocean consolidated to three main entries on the east and west edges of the Kamoamoa flow and near the west edge of the Lae`apuki flow.

The missing visitor to Hawai`i Volcanoes National Park serves as a tragic reminder that active volcanoes can be unpredictable and dangerous, however passive and approachable their eruptions. Kīlauea is no exception.

The 10-year-long eruption on Kīlauea's East Rift Zone continued this past week. Lava is erupting from the episode 51 and 53 vents on the southwest side of the Pu`u `O`o cone, but is being carried towards the coast entirely within underground lava tubes as far as the top of the pali.

The eruption near Pu`u `O`o on Kīlauea's East Rift Zone continues, with lava entering the ocean both east and west of Kamoamoa and at Lae`apuki.

In historical times, two tsunamis occurred during the first week of April. The first of these occurred on April 2, 1868; it resulted from the great earthquake that took place that day near Pahala.
