The Shinmoedake entered in a brief eruption this 14th May at 14.44. A plume of ash and gas rose up to 4,500 meters above the crater, then dispersed to the southeast. The activity lasted until 16h.10.

This is the first manifestation of this crater since April 6th.

The alert level of the volcano, set at "3 / do not approach the volcano" since March 15, 2018, has not been modified.

" I took a walk around a pond after a long absence. Because of Iwozan fumarol, I can only go from Ebino no Kogen to Rokkanison Pond (Oike). Coincidentally, Shinmukake has exploded. According to the report, the plume was raised to a height of 4,500 m. It is about 4 Km from the shooting point to Shinmoedake, but the wind direction was fortunate and ash did not wear."

In the evening, although no geodetic observations indicate a new magmatic ascent, an incandescence marked the lava slab, broken by the eruption of the day (observation of Fumihiko Ikegami / UTAS)

14.05.2018 / 7h loc. - Video by Andrew Hara, Daryl Lee, audio by Hawaii County Civil Defense

The activity of the fissure # 17 on the east end of Kilauea's east zone rift was marked yesterday by fountaining, the spatter explosion at more than 30 meters high and the advance of a lava flow a"a, in several lobes, to the north-east parallel to Highway 132.

An overflight late afternoon let see that the lava flow made a turn to the southeast, towards the ocean, and following a drainage in an unoccupied area.

The fissure # 18, active since the 13 at the end of the day, is only weakly.

Vigilance moved to a new crack in the Lalipuna Gardens subdivision, just at the edge of the geothermal facilities. Helicopter overflight shows cracks, lava and degassing.

Deflation continues at the summit of Kilau, where seismicity remains high.

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 in the last 24 hours

Many resurgences are sometimes visible, as in the evening of May 14, with a lava flox at the foot of Piton de Bert (right in the photo), the point of view where hikers must go.

Eruptive cone activity is much more discreet.

The activity now taking place mostly in lava tunnels, surface flows could not be estimated today from the satellite data.
The CO2 concentrations in the air at the top and the CO2 concentrations in the soil in the Plains region remain high.

The inflation of the building seems to resume. This parameter will be confirmed in the coming days.
