Asamayama (Japan)

A new eruption, or volcanic unrest was detected by the volcanologists an published by the GVP. The details are summarized in the following message:

On 25 June JMA raised the Alert Level for Asamayama to 2 (on a scale of 1-5) noting that inflation on the W flank had been recorded since 20 June. The number of shallow (just below the summit, or 1-2 km a.s.l.) volcanic earthquakes had also increased; two volcanic tremors were detected on 20 June. Emissions form the summit crater had not changed and continued to be white in color and rise no more than 200 m above the crater rim.

Makushin (United States)

A new eruption, or volcanic unrest was detected by the volcanologists an published by the GVP. The details are summarized in the following message:

AVO reported continuing numerous smaller earthquakes in an area about 10 km E of the Makushin?s summit at a depth of about 8 km during 24-30 June; the frequency and magnitude had been declining since 15 June but the rate became variable on 24 June. No surficial activity was visible in satellite or webcam images; only typical minor steaming from summit crater lake. Earthquakes with a M 3 and M 3.8 were recorded at 1653 and 1802 on 28 June, with the larger event strongly felt in Unalaska (14 km E). The Aviation Color Code and Volcano Alert Level remained at Yellow and Advisory, respectively.

Turrialba (Costa Rica)

A new eruption, or volcanic unrest was detected by the volcanologists an published by the GVP. The details are summarized in the following message:

OVSICORI-UNA reported that occasional small ash emissions rose no higher than 100 m above the active crater at Turrialba each day during 23-29 June; no emissions were recorded on 27 June. A series of ash emissions were recorded at 1348, 1739, and 2303 on 28 June and at 0107, 0232, 0306, 0412, and 0818 on 28 June. At least two of those events (0107 and 0412) were accompanied by ballistics that were ejected onto the N wall of the active crater.

Aira (Japan)

A new eruption, or volcanic unrest was detected by the volcanologists an published by the GVP. The details are summarized in the following message:

JMA reported that during 22-26 June two eruptive events at Minamidake Crater (at Aira Caldera?s Sakurajima volcano) produced plumes that rose as high as 1,300 m above the crater rim. An explosion at 1807 on 28 June ejected material 1,000-1,300 m away from the crater and produced a plume that rose 600 m above the crater rim. The Alert Level remained at 3 (on a 5-level scale).

Dukono (Indonesia)

A new eruption, or volcanic unrest was detected by the volcanologists an published by the GVP. The details are summarized in the following message:

Based on satellite and wind model data, and information from PVMBG the Darwin VAAC reported that during 24 and 26-30 June ash plumes from Dukono rose to 2.1 km (7,000 ft) a.s.l. and drifted NW and W. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Sangay: Thermal anomalies detected

The Ecuadorian volcano Sangay is still active. Today, explosive eruptions were detected, which caused volcanic ash to rise to an altitude of 6400 m. The ash was drifted westward. In a special report of the IGEPN the morphological changes of the volcano caused by the eruptions were investigated. Most striking is a depression on the southeast flank. It was carved into the flank by lava flows, debris avalanches and pyroclastic flows. The gorge is almost 400 m wide, 4 km long and starts from the crater. Three thermal anomalies have been detected in it. 2 of the anomalies are located in the upper part of the canyon. The top anomaly is in the crater area and marks an explosive vent. The 2nd anomaly is below the base of the crater and represents the source of the lava flows. The 3rd heat source is located in the lower part of the gorge and is probably generated by an accumulation of hot deposits of pyroclastic flows.
