Another moderate (4.1 magnitude) earthquake rumbled through the Kilauea Summit area shortly after 2 p.m. HST.

Here’s the latest information from the Hawaii County Civil Defense Agency:

A message from COUNTY OF HAWAII

This is a Civil Defense message for Friday, August 3 at 4:00 in the afternoon.

The Hawaiian Volcano Observatory reports that earthquakes continue at Kilauea summit. At 2:24 pm, a magnitude 4.1 earthquake occurred in the summit caldera that produced a rockfall. Fissure 8 continues to erupt lava into the perched channel, sending flows to the ocean at Ahalanui and creating a large laze plume. The margin of the flow at the ocean entry has not advanced and remains approximately 500 feet from the Pohoiki boat ramp.

Motorists on Highway 11 between the 28 and 32 mile marker are advised to stay on the pavement, be alert for changing roadway conditions, and drive with caution. Motorcyclists and bicyclists should proceed with extreme caution.

The following guidelines remain in effect:

  • Check all utility connections of water, gas, and electricity for potential damage from earthquake activity.
  • Do not access the active flow field due to extreme hazard. Be aware that channel overflows and other breakouts are possible on the active flow field.
  • The ocean entry continues to produce a laze plume. Take precautions and stay out of the plume to avoid exposure to hydrochloric acid and glass particles, which can irritate the skin, eyes, and lungs.

We are on watch 24-hours a day for your safety.
This is your Hawai‘i County Civil Defense Agency.”
