Kilauea Volcano: Elevated Seismicity, Increased Effusion

Volcano Shows Increased Effusion Rates, Significantly Elevated Seismicity at summit and east rift zone

HVO/USGS Volcanic Activity Warning

Volcano: Kilauea (CAVW #1302-01-)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE
Previous Aviation Color Code: RED

Issued: Monday, March 7, 2011, 6:13 PM HST (March 8, 2011, at 04:1UTC)
Source: Hawaiian Volcano Observatory
Notice Number: 2011/H2
Location: N 19 deg 25 min W 155 deg 17 min
Elevation: 4,091 ft (1,247 m)
Area: HI Hawaii and Pacific Ocean

Volcanic Activity Summary from HVO:  Eruption continues at Kīlauea volcano’s east rift zone  with intermittent activity at alternating locations along a 2.3 km long fissure between Pu’u ‘Ō’ō and Nāpau Crater. Effusion rates are high, with lava spatter reaching as high as  30m.

East rift zone gas emissions are significantly elevated above the 300 tonnes/day measured during the past several months and as recently as March 5, prior to the fissure eruption. Gas measurements on March 6 show an average SO2 emission rate of 10,000 tonnes/day, the highest measured on the east rift zone since an eruptive surge in July 2008 produced an emission rate of 7,000 tonnes/day. Summit SO2 emissions on March 6 were around 600 tonnes/day.

The TEB eruption system downrift (ENE) of Pu’u ‘Ō’ō appears to have shut down. During today’s overflight of the flow field, no active lava flows were observed on the pali or coastal plain.

Seismicity remains significantly elevated at both Kīlauea’s summit and east rift zone.

Deflation appears to be slowing at the summit and east rift zone.

At Kīlauea’s summit, the lava lake within the Halema’uma’u Crater vent is about 200 m deep, based on visual estimates. A rockfall within the vent at 2:23 p.m. HST today produced a vigorous dusty brown plume.

The fissure is located just west of Pu`u `Ō `ō Crater. Spatter was reaching heights of 40 m (130 ft). Source: HVO

Most of the day’s activity was focused at this vent, around which a low cone was forming. Pu`u `Ō `ō is visible in the background to the northeast. Source: HVO
