Mt erebus eruption update#

In a 2 June advisory PHIVOLCS reported continuing low-level unrest at Taal. Residents were reminded to stay away from the 6-km-radius Permanent Danger Zone (PDZ). PHIVOLCS noted that although low-level volcanic earthquakes, ground deformation, and volcanic gas emissions indicated unrest, the steep increase in rockfall frequency may indicate increased dome activity. At 1000 on 5 June the Alert Level was raised to 2 (on a 0-5 scale). Short-term inflation on the upper flanks had been detected since February.įrom 0500 on 4 June to 0500 on 5 June the number of rockfalls increased from an average of 5 events per day to 49 events per day. Electronic Distance Measuring (EDM), precise leveling, continuous GPS, and electronic tilt monitoring data showed that the volcano had been slightly inflated, especially on the NW and SE flanks, since 2020. A total of 26 volcanic earthquakes had been recorded since 1 April. Sulfur dioxide emission averages were as high as 576 tons per day on 29 April and 162 tons per day on 23 May. The lava dome increased in volume by about 83,000 cubic meters during 3 February-9 May, with a total addition of nearly 164,000 cubic meters since 20 August 2022.

Complete updates are done about every 6-8 weeks, but information about newer eruptions can be found in the Weekly Report.ĭaily visual and webcam observations of Mayon’s summit crater revealed more frequent rockfalls at the summit lava dome starting in the last week of April, indicating aseismic dome growth.

Mt erebus eruption update#

An eruption listed here might have ended since the last data update, or at the update time a firm end date had not yet been determined due to potential renewed activity.

The most recently started eruption is at the top, continuing as of the Stop Date given.

The Smithsonian / USGS Weekly Volcanic Activity Report (WVAR) for the week ending on 6 June 2023 includes the 29 volcanoes shown below marked 'Yes' in the WVAR column (rollover for report). Additional eruption data is available for recent years. Detailed statistics are not kept on daily activity, but generally there are around 20 volcanoes actively erupting on any particular day this is a subset of the normal 40-50 with continuing eruptions. An eruption marked as 'continuing' does not always mean persistent daily activity, but indicates at least intermittent eruptive events without a break of 3 months or more. Overall, 49 volcanoes were in continuing eruption status as of 14 April 2023.
