News of Kilauea, Piton de la Fournaise, Erta Ale, Karymsky and Yellowstone.

The eruption continues in the lower east rift zone of Kilauea.

The HVO confirms the opening of a new outbreak on the morning of May 13 800 meters northeast of Hinalo St. and Highway 132.

The fissure # 17 is several hundred meters long, and produces spatters ... a lava flow has progressed from this vent.

Civil Defense ordered the evacuation of Hale Kamahina Loop Road

Around 10:30, cracks appeared in Hwy 132.

At around 14:00 HST, a small lava buffer appeared between cracks 16 and 17, with crack stagnation; this small outbreak was designated crack # 18.

The Civil Defense reports degassing and spattering at 18h.locale.

Concerning the crater of Pu 'O'o which had collapsed on April 30th, an overflight in good weather made it possible to take images which show the deepest parts of the crater at 350 meters under the rim.

At the summit, on May 13, a vigorous plume of steam, with occasional small amounts of ash, overcame Overlook Crater, drifting southwest.

On the morning of the 13th, the HVO reports that deflation is pounding in the summit area, with high seismicity ... but Scott Rowland indicates at the end of the day that the GPS data no longer show any noticeable change.

At Piton de La Fournaise, the eruption started on April 27, 2018 at 11:50 pm local time continues. The intensity of the volcanic tremor (indicator of surface eruptive intensity) has remained relatively stable over the last 24 hours.

The activity is still predominantly in the lava tunnel.

During the last two days, the morphology of the main cone (the most active) has evolved with the building of a small outgrowth at its apex and a narrowing of the apical mouth. The lava projections have become rare either at the level of this main cone or at the level of the secondary cone further upstream.

The activity now taking place mostly in lava tunnels, surface flows could not be estimated today from the satellite data.

The SO₂ flux (recorded on the OVPF NOVAC stations) continues to decrease, consistent with a decrease in surface lava flow. Nevertheless, CO₂ concentrations in the top air and CO₂ concentrations in soil in the Plains region remain high.

In Afar, at Erta Ale, the thermal anomaly, discribed in recent days by Mirova and the Sentinel 2 satellite SWIR, remains high and comes mainly from the distal lava field and the intracaldeira pit crater.

A weak manifestation of breakout between the position of the "new" lava lake, which no longer radiates on these images, and the distal field.

In Karymsky, a moderate explosive activity is reported on 13.05.2018 by the KVERT; it is accompanied by an ash plume of 3,000 - 3,500 meters high, then extending about thirty kilometers to the southwest of the volcano.

The aviation code remains at the Orange.

In the Norris geyser basin of Yellowstone National Park, the fifth (watery) eruption of the Steamboat geyser occurred on May 13th just before 4am local time.

The episode was recorded by the seismometers and an increase in the probe discharge that has just been replaced a few days ago.

It seems that this geyser is entering a phase of more common watery eruptions ... which does not imply a Yellowstone activity in general, but could benefit either lucky photographer during the 'summer.
