Map showing locations of USGS NetQuakes recorders and epicenter of M3.2 earthquake occurring on April 3, 2013. Around the map are plots of the strongest shaking recorded at each of the NetQuakes sites associated with this earthquake. The plots are not adjusted to reflect differences in shaking among the individual sites.

The two active flows (Kahauale‘a and Peace Day) are both fed from vents high on Pu‘u ‘Ō‘ō cone. This view (looking southwest) shows Pu‘u ‘Ō‘ō crater. In the foreground, a lava pond and small spots of orange glow mark the location of the vent for the Kahauale‘a flow.

This steep spatter cone near the north rim of Pu‘u ‘Ō‘ō crater was making loud gas jetting sounds, presumably due to gas forced through the small glowing holes near the top of the cone.

Another view of the ocean entry points and discolored water at Kupapa‘u. The thermal camera today showed that water surface temperatures were up 50 degrees Celsius (122 degrees Fahrenheit) a short distance out from the entry points. Just beyond the ocean entry, the light colored areas represent active breakouts. On the pali, fume marks the path of the lava tube.

A closer look at the start of the lava tube on the Kahauale‘a flow, near the rim of Pu‘u ‘Ō‘ō crater. See photo above for aerial view. Unfortunately a direct view of the lava stream was not available here.

The Kahauale‘a flow remains active, with the flow front today about 4.9 km (3 miles) northeast of Pu‘u ‘Ō‘ō. The flow is still on earlier Pu‘u ‘Ō‘ō flows, but has been slowly approaching the edge of the forest.

Numerous ocean entry points were active today at Kupapa‘u, with a plume of discolored water drifting west.

Pele's hair covers much of the ground in the area immediately downwind of the vent at Halema‘uma‘u Crater. Accumulations about a meter (yard) wide are found on the windward sides of the curbs in the Halema‘uma‘u parking lot, which is closed to the public because of the ongoing volcanic hazard (May 3, 2012).

Assessing how storms move sediment during storms provides coastal scientists and managers the information they need to keep coastal communities safe and prosperous. And, lucky for us, provides many opportunities to see great coastal sunsets!

The Kahauale‘a flow, at the center of the photo, has reached 4.4 km (2.7 miles) northeast from its source in Pu‘u ‘Ō‘ō, which is in the background.

The Kahauale‘a flow has been outlined in this image for comparison with the previous photo.
