• New Earthquake Activity in Mount Agung Recorded Seismic Tools PVMBG, Here’s the PVMBG Analysis

    Mount Agung was photographed from Sanur Beach, Denpasar, Sunday (29/10). The Center for Volcanology and Geological Hazard Mitigation (PVMBG) announces Mount Agung’s latest status from Awas to Standby.

    SEMARAPURA – The evaluation of volcanic activity of Gunung Agung period, Sunday (12/11) at 18.00 to 24.00 Wita again showed new seismic data.

    The PVMBG team recorded a low frequency frequency, with a duration of 31 seconds.

    This earthquake was first recorded by seismic devices PVMBG in Post Monitor Mount Api Agung, since Mount Agung has increased volcanic activity.

    Head of Sub-Field Mitigation Monitoring Volcano East Region PVMBG, Devy Kamil Syahbana explained, low frequency earthquake is a seismic that occurred in shallow depths.

    According to the epicenter of this type of typically occurs dikedalaman around hundreds of meters to 2 Km, due to the flow of magmatic fluid.

    However, it does not mean if the earthquake indicates the current magma activity recorded hundreds of meters up to 2 km from the crater of Mount Agung.

    “It’s not the magma of liquid, it’s probably just the gas that passes, then to the surface and out so white smoke as a form of energy release,” explained Devy when confirmed, Monday morning (12/11/2017)

    Meanwhile, based on monitoring results of the period, Monday (14/11) at 00.00 Wita, Mount Agung again experienced 2 times the earthquake gusts.
    Devy explains, the earthquake is a sour earthquake sourced on the surface. The epicenter was only about a hundred meters away.

    “This earthquake will come out in the form of smoke, a blast earthquake is recorded only if the energy is large enough,” explained Devy.

    Until now, the average seismicity of Mount Agung is still in the number 50-70 times the earthquake per day. Visually, the low pressure crater smoke was observed white with a thin intensity and height of 100-300 meters above the peak crater.

    Status of Mount Agung was still in level III (Siaga)
    “We are still monitoring the progress of Mount Agung’s activities to date have not been normal, but still show a fairly high vulcanic activity,” explained Devy. (*)
