 Kilauea volcano (Hawai'i), activity update: lava flow from Thanksgiving Eve Breakoutjeudi oct. 23, 2008 18:00 | AUTEUR : TS
HVO reported that during 15-21 October lava flowed SE through a tube system from underneath Kilauea's Thanksgiving Eve Breakout (TEB) and rootless shield complex, reaching the Waikupanaha ocean entry. Multiple surface lava flows on the pali were noted; on 16 October a channelized 'a'a flow was active in the Royal Gardens subdivision and a pahoehoe flow was seen on the W side of the active flow field. Lava destroyed one of two remaining intermittently occupied structures in the subdivision. The sulfur dioxide emission rate at Pu'u 'O'o was 1,000 tonnes per day on 17 October, half of the background rate of the 2005-2007 average. Explosions at the ocean entry were reported on 19 October.

It was reported that during 3-9 September, lava flowed SE through a lava tube system from underneath Kilauea's Thanksgiving Eve Breakout (TEB) and rootless shield complex, reaching the Waikupanaha ocean entry and one further to the E. On 5 September, geologists saw multiple surface flows during an aerial observation: four on the coastal plain, and a large 'a'a flow and a small pahoehoe flow in the abandoned Royal Gardens subdivision.

After several weeks of elevated explosive activity at the summit of Kilauea volcano, the Halema'uma'u vent which opened on March 19 has doubled in size to a current diameter of 65 m (215 ft), allowing scientists hovering above on September 9 the first views of a now-exposed lava lake about 100 m (330 ft) below the vent rim. The lava lake, estimated to be 50 m (160 ft) in diameter, was seen to be roiling, bubbling, and overturning, with its surface level rising and falling as a result of gas pistoning, periodic bursts that release coalescing gas bubbles from beneath the lake's frozen crust in an explosion of lava rock and spatter. ...

HVO reported that during 13-19 August, lava flowed SE through a lava tube system from underneath Kilauea's Thanksgiving Eve Breakout (TEB) and rootless shield complex to the Waikupanaha ocean entry. Earthquakes were in various locations along the Koa'e fault system, S and W of the caldera, beneath the summit, along the S-flank faults, and along the E and SW rift zones. The vent in Halema'uma'u crater continued to produce a predominantly white plume with minor ash content that drifted mainly SW.

Kilauea continues to be active at two locations: At the summit, ash elevated sulfur dioxide emissions continue from the Halema`uma`u vent, accompanied by elevated levels of seismic tremor. At the east rift eruption site, lava is flowing through lava tubes and entering the ocean at the Waikupanaha entries.

There are no significant changes at Kilauea volcano, which is active from two locations: at the summit, the new vent in Halema`uma`u crater continues to erupt ash and emit elevated lamounts of sulfur dioxide, accompanied by higher levels of volcanic tremor. At the coast, lava continues to flow into the ocean at the Waikupanaha and Ki ocean entries.
