Small-scale map of June 27th flow in Kīlauea's ERZ

This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone as of September 6, 2014. The area of the flow on September 3 is shown in pink, while widening and advancement of the flow as mapped on September 6 at ~11:10 AM is shown in red. The front of the active flow was 13.2 km (8.2 miles) from the vent and 1.4 km (0.9 miles) from the east boundary of the Wao

Overflight Showing Flow Activity

This Quicktime movie shows activity at the front of the June 27th lava flow. The flow front continues to advance eastward, with lava issuing out of a ground crack and spreading through dense forest, creating thick plumes of smoke. The farthest lava this afternoon was 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna forest reserve.

Lava Flow Activity

The June 27th lava flow remains active at its leading edge, where lava is spreading out slowly into thick forest and also plunging into one of the many deep ground cracks that form Kīlauea's East Rift Zone. This Quicktime video shows the activity near the eastern edge of the flow. This swiftly moving stream of lava was about 2 meters (yards) wide, and was visible down to

Lava Flow Activity

The Quicktime video begins with a view of the steaming ground crack, where lava is moving deep within the crack. As the view rotates west, lava can be seen on the surface burning thick forest. Finally, the camera focuses on the eastern edge of the flow, where lava is plunging into the deep ground crack. This swiftly moving stream of lava was about 2 meters (yards) wide,

Over the years HVO has attempted to maintain its scientific energy, enthusiasm, and insights by melding a permanent staff with a smaller cadre of rotating, research-oriented scientists. The observatory has about one rotating researcher for every four or five permanent staff. Rotating scientists generally stay 3-5 years.

"Wekiu" is the Hawaiian word for top or summit. This name was given to Mauna Kea's tallest cinder cone, which reaches 13,796 feet in elevation and is the highest in the Hawaiian archipelago. Life on the Mauna Kea summit must endure freezing temperatures, winter snow falls, and, occasionally, hurricane-force winds.

As we enter the month of May, we are remiss in not remembering that April was "Tsunami Awareness Month". April was chosen as "Tsunami Awareness Month" because the deadliest tsunami to strike the Hawaiian Islands occurred on April 1, 1946. What is often overlooked is that the largest and deadliest locally generated tsunami also occurred in the month of April.
