  The explosive eruption at the volcano continues. The volcano produces near-frequent small to moderate ash emissions and occasional larger, vigorous vulcanian-type explosions. On 29 August, the local KVERT institute informed about a quite intense eruption from the active crater. A billowing grey abundant ash column rose about 1,6 km above the vent and drifted southeast. Heavy fall of dark masses included lapilli-to-bomb-sized fragmented material as well. The event was accompanied by volcanic lightning. So-called dirty thunderstorms form when ash that is to be erupted begins as electrostatically neutral rock fragments. Heat and motion of fragmented material within volcano edifice is among the first source of particle charging, then another fundamental phenomenon to being charged is friction. In order to create volcanic lightning, neutrally charged ash particles must come in contact with another object of differently charged qualities. A thermal anomaly was identified in satellite image

 

 

 

 

    The explosive eruption at the volcano continues. The activity is dominated by near-constant, sometimes vigorous vulcanian-type eruptions. A powerful event occurred from its summit crater on 25 August in late evening. An increasingly spectacular grey ash-rich column rose about 4 km above the vent and drifted northwest. The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 4 km distance from the crater.

 

 

 

 

 

  The elevated seismic unrest at the volcano continues. A swarm of small (mean values of M 2.0 mostly), but intense earthquakes have been occurring beneath the southern flank of the Kilauea caldera over the past two days, the Hawaiian Volcano Observatory (HVO) reported. Most of earthquakes have been located at depth of 2-3 km below the surface. Ground deformation summit tiltmeter recordings indicate the ongoing inflationary trend over the past day with some variations. The summit area is being increasingly pressurized. Similar episodes of earthquake and ground deformation activity occurred in November 2020 and August 2021, prior to eruptions in December 2020 and September 2021. For now, whether an eruption will occur or not, it's unclear yet. The current elevated seismic activity may culminate in the upcoming days, weeks or even months or may decrease to the background levels.

  Volcanic unrest continues at the volcano, characterised by continuing uplift, seismic swarms involving quakes felt by the local population, and intense degassing from various fumaroles and through diffuse ground emissions. Some of these phenomena have increased in intensity over the past weeks. However, it is believed that chances of an eruption in a near future are still very low, but the situation should be monitored very closely. The observatory in Naples (OV-INGV) published a detailed article based on its latest monitoring data, evaluating the situation. It is reported that ground deformation, centered around the area of Pozzuoli, not only continues but its rate has increased in recent weeks: Between August 14 and 20, 2023, the average value of the uplift rate in the area of maximum deformation was about 15 mm/month, OV-INGV writes. Since the current episode of uplift started in 2005, the slow ground uplift has reached 111 centimeters in the Rione Terra area in total. In addit

 

 

  The Icelandic Meteorological Office's (IMO) field research on the volcano took place last week. Scientists Dr. Melissa Anne Pfeffer and Dr. Michelle Parks visited the area to make a geochemical and ground deformation survey accompanied by other scientists and park rangers. Preliminary results don't hint any significant changes in gases and/or water so far (current measurements are still ongoing) compared to previous years. Temperature and pH analysis don't show clear changes in the geothermal activity within the Viti crater. On 12 August, a steam plume was reported at the cliff of Bátnshraun, but this was recognized as dust, resulting in a minor rockfall on the steep slope of the caldera. About the ground deformation investigation, five GPS stations were set up at various locations within the caldera. Electronic tilt recordings, measured on the 1921 and 1961 lava fields, brought no significant inflation since the last analysis in August last year. Source: Icelandic Meteor

  The explosive eruption at the volcano continues. An abrupt strong eruption occurred from the summit at noon on 20 August. At about 12:47 local time, an increasingly thick black plume rose to an altitude of 22,000 ft (6,700 m) and drifted north. The explosion came during a phase of generally low activity over the past week and had no detected seismic precursor. It was associated with 53 emissions of gas, water vapor and ash. The crater area of the volcano remains closed for climbing as the risk of being caught in sudden explosions is very high. The alert status remains at Level 2. People are advised to avoid the crater area within a 12 km radius. Additionally, the warning bulletin states that lahars (mud flows) could also occur if heavy rainfalls remobilize fresh ashfall deposits.

  A explosion occurred yesterday morning inside the summit crater of the volcano. At 9.05 a.m. local time, dense jets of light to dark-gray ash and rocks, mixed with white steam, were ejected in a sudden, violent blast from the crater. The ash plume, also seen from people near the base of the volcano, rose a few hundred meters and quickly dissipated after the end of the eruption. Climbers who were on the crater rim at the time filmed the event and could escape unharmed: lekas sembuh dempo  pic.twitter.com/M3J2G2S3Fm   According to information from the Indonesian volcanological survey BVMBG, the eruption was likely phreatic in origin, i.e. entirely driven by steam explosion without ejecting fresh magma, which fits the visual style of the eruption, typical for such dangerous, and usually unpredictable explosions. The corresponding seismic signal had a maximum amplitude of 35 mm and lasted for 182 seconds. The volcano started to show new signs of activity last year already; seismic unrest

 

 

 

 

 

 This time,I referenced relationship with Gilbert of Manengouba.Yes,my other reference as evaluated is pacific-antarctic divergent zone as ~75 km👍Next,I observed correlation with M5.5 event(e machala) of  orthogonal distance to this zone😐Thus,I can express 'offshore  kota tanjungbalai' as precious focus for some geoenv😐 Ekrem Erkuş Geophysics Eng/TURKEY
