The Puu Oo lava flow is prompting fresh concerns as it continues its march toward populated areas.

This week, the Hawaiian Volcano Observatory bids aloha to interns Pua Pali and Greg Javar, who gained first-hand experience monitoring volcanoes and earthquakes by working with U.S. Geological Survey scientists this summer.
The U.S. Geological Survey’s Hawaiian Volcano Observatory resumed monitoring volcanoes and earthquakes Aug. 13, officials said.
The popular forested trail at Kipukapuaulu, Namakanipaio campground, and Mauna Loa summit and backcountry within Hawaii Volcanoes National Park are now open.
HONOLULU — U.S. Geographical Service outposts in other states are helping monitor Hawaii’s volcanoes and earthquakes while work is done to repair Tropical Storm Iselle’s damage to the Hawaiian Volcano Observatory.
Intermittent disruptions in eruption updates, webcam imagery, earthquake data, and other information normally available on the U.S. Geological Society Hawaiian Volcano Observatory website could continue for the next few days.
We’ve learned a lot about Kilauea’s explosive history in the past 15 years. Once thought to be rare, explosive eruptions from the volcano’s summit are instead frequent and clustered into periods lasting several centuries. For example, between 1500 and the late 1700s, Kilauea’s eruptions were almost always explosive. We can be thankful that Kilauea is in a quiet period now, but we shouldn’t have an ostrich mentality about the future. If it happened yesterday, it can happen tomorrow.
On July 18, newspapers across the United States published a story titled “Quake risk rises for much of U.S.”
A new National Park Service report for 2013 shows that the 1,583,209 visitors to Hawaii Volcanoes National Park spent $124,937,400 in communities near the park. This spending supported 1,476 jobs in the local area.
William Ellis led a team of missionaries on a tour of the Island of Hawaii starting on July 18, 1823, from the village of Kailua. Their trip took them around the southern coast of the island and inland through the east Ka‘u District. When they were in the vicinity of Kapapala, a short distance northeast of Pahala, their attention was drawn to some rising columns of “smoke” a few miles away.
Scientists and technicians from volcano observatories in 11 countries recently visited the U.S. Geological Survey’s Hawaiian Volcano Observatory to learn techniques for monitoring active volcanoes.
For the past year, the Kahaualea 2 lava flow was erupting from a vent high on the northeast crater rim of Puu Oo, on Kilauea’s east rift zone, sending lava toward the northeast. Although this lava flow advanced very slowly, and erratically, it was uphill from residential areas and posed a potential future hazard. Several interruptions to the lava supply at the vent occurred over the past year but nothing large enough to terminate the flow. In the early morning of June 27, the terminal event finally arrived.
The Kahaualea 2 lava flow officially met its demise this week.
There’s new activity at Puu Oo crater.
A few weeks ago, a Volcano Watch article recounted the advance of Mauna Loa lava on the town of Hilo in 1855. Titus Coan, a fervent investigator and observer of all things volcanic, was in his mid-50s at the time and walked up to the source of the flow at least seven times between August 1855, when the eruption began, and February 1856, when the lava flow stopped. By the end of the eruption, Coan understood how lava flows advanced with a level of detail that no one else had achieved before.
