Location of selected earthquakes greater than magnitude 6, Island of Hawai‘i.
November 18, 1994

Eleven years ago on November 16, residents of Hawaii were awakened by a strong earthquake at 6:13 a.m. The earthquake had a magnitude of 6.6 and was located beneath the Kaoiki Fault Zone between the summits of Mauna Loa and Kīlauea Volcanoes.

The eruption along Kīlauea's east rift zone is approaching its twelfth anniversary, now less than two months away. The eruption continues strongly, with magma replenishment beneath the summit roughly matching eruption rates.

Beginning on October 21 and continuing through October 31, residents in parts of lower Puna have felt a sequence of small earthquakes.

The nearly twelve-year-long eruption on Kīlauea's east rift zone had at least one additional pause in activity this past week.

Not only does Hawaii move up and down, as I described last week, it also moves horizontally. There are several ways to measure these movements, and a new, exciting technique has recently been added to the repertoire.

There is abundant evidence that the island of Hawaii is sinking, and that different parts of the island sink, or subside, at different rates and for different reasons. At any location, the net subsidence is the sum of these different types of subsidence and any change in global sea level.

The nearly 12-year-long eruption on Kīlauea's east rift zone took a short vacation this past week. No lavaerupted between Wednesday morning and Thursday afternoon, when lava once again reoccupied the same tube to the western ocean entry at Laeapuki and a small channelized 'a'a flow broke out of the tube in the center of the flow field above Kamoamoa.

Rabaul caldera, an active volcano located on the northern tip of New Britain island in Papua New Guinea, erupted violently this past week.

The Hawaiian Volcano Observatory is located on the northwest rim of Kīlauea caldera adjacent to the Jagger Museum. Because of its location within Hawaii Volcanoes National Park, many people have the mistaken impression that the Observatory is administered by the National Park Service.

Kīlauea's east rift zone eruption at Pu'u 'O'o, which began in January 1983, continues. Lava is actively circulating in a pond inside the Pu'u 'O'o cone.

About nine months ago I wrote about a scientific drill hole in Hilo that was funded by the National Science Foundation to examine the long-term growth of a Hawaiian volcano.
