Tremor levels at steady rate at Kilauea Volcano
Advertiser Staff
According to an update released by Hawaiian Volcano Observatory about 12:15 a.m. today, activity at Kilauea Volcano has not changed significantly at the summit or East Rift Zone since 6 a.m. yesterday. The summit shows only slight inflation and tremor levels continue at a steady rate.
In the upper East Rift Zone, fewer than about 10 small earthquakes per hour are being recorded, only two of which could be located since 7 p.m. yesterday. Tremor levels in the Kane Nui o Hamo area have remained relatively constant.
At Pu'u 'O'o, a tiltmeter continues to indicate steady collapse of the cone. The webcam on the rim of Pu'u 'O'o crater is not showing any visible glow.
The observatory has scheduled another overflight for early afternoon, and continues to monitor the situation closely.
The pace of earthquakes picked up dramatically early Sunday, signaling the start of the latest changes at the volcano, which has been erupting continuously since 1983.
Magma that forced its way into Kilauea's upper East Rift Zone caused hundreds of earthquakes and reached the surface late Monday or early Tuesday at Kane Nui o Hamo to create a new area of eruption before stalling out.
