There was no significant inflation or deflation at the summit of Kilauea Volcano over the past day. The summit lava lake remains close to the rim of the Overlook crater and overflowed slightly onto the floor of Halema’uma’u Crater several times over the past day. Seismicity beneath the summit and upper East and Southwest Rift Zones is elevated. At the East Rift Zone eruption site, widespread breakouts are active within about 8 km (5 mi) of Pu’u ‘O’o.
A closer look at the lava lake and overflows on the floor of Halema’uma’u Crater. The outline of the Overlook crater, and the active lake, is easier to distinguish in this view.
There was no significant change in tilt at Kilauea’s summit over the past day. The lava lake level has been at, or near, the rim of the Overlook crater over the past day. The lake overflowed a very short distance onto the floor of Halema’uma’u Crater several times over the past day. Yesterday the lava lake level was measured at roughly 4 meters (yards) above the original (pre-overflow) floor of Halema’uma’u Crater. The recent overflows have accumulated and built the rim of the Overlook crater up several meters (yards) above the original floor of Halema’uma’u Crater. This morning, the lava level is close to the rim of the Overlook crater. Seismicity is elevated beneath Kilauea’s summit and upper East and Southwest Rift Zones. Sulfur dioxide emission rates averaged 4400-5400 tonnes/day for the week ending April 28.
From this angle, the extent of the lava lake within the Overlook crater is much easier to distinguish from the surrounding overflows. The closed Halema’uma’u parking lot is in the right side of the photograph.
Pu’u ‘O’o Observations:
The tiltmeter on the north flank of Pu’u ‘O’o recorded deflationary tilt over the past day. Otherwise, there were no noticeable changes at Pu’u ‘O’o. The sulfur dioxide emission rate from all East Rift Zone vents was about 700 tonnes/day when last measured on April 28, 2015.
June 27th Lava Flow Observations:
Webcam views of nighttime incandescence and daytime smoke indicate that surface flows remain active northeast of Pu’u ‘O’o. The most distant activity was burning forest about 8 km (5 mi) northeast of the crater, based on field mapping on April 23 and more recent satellite images.

Turrialba, Costa Rica :
An eruption occurred yesterday on the Turrialba volcano at 15:24. This eruption emitted an ash column of about 2500 meters above the summit of the volcano. The wind direction has scattered the ashes to the Central Valley.
The eruption ejected rocks that damaged the solar panels as well as the toll of park rangers located 700 meters from the crater.
The volcano has had a very active night with emanation of pulses of ashes that occur with some regularity. 3:20 After the summit remained cloudy until now.

Misti, Perou :
Between 16 and 30 April 2015, the type of VT events or fracturing showed a decrease in the incidence rate, from 33 to 20 events / day. There was no presence of seismic swarms of VT events. This seismicity, which is still low magnitude (<2.0 ML) is located within the volcanic edifice, with depths between 1 and 2 km. The biggest VT event recorded in this period took place at 11h05 on 19 HL (16: 05UTC), with a magnitude of 1.9 mL, and was located 1 km northwest of the crater.
Earthquakes LP type associated with the passage of fluids (gas and steam) in the Misti volcano have a rate of low occurrence, which remains at 6 LP / day. The tremor activity decreased by 28% compared to the previous period, and the energy still appears low. In this period, the power curve showed no significant variation and weak (
It was not detected by thermal anomalies, and high density values for SO2 on the Misti volcano.
