Seismic amplitudes tend to fluctuate and haven't shown a clear pattern. Prior to the 28-29 June 2018 eruption, rapid inflation occurred with 1 cm uplift. Since then, there has been deflation. Deformation still indicates development of magma pressure at depth. #Agung 3/

Satellite images show ongoing effusive eruption of lava into the crater. From 28 June to 1 July 2018, new lava flows out from the center of the crater & spreads radially with volume in the range of 4-5 million cubic meters. 4/

Since 21 Nov 2017 (to 1 July '18), the total volume of lava has reached 27-28 million cubic meters or nearly 50% of the crater of
#Agung, which is ~60 million cubic meters. 5/1 odpowiedź 3 podane dalej 5 polubionychPokaż ten wątek -
Satellite images still record the existence of hotspots (high temps) in the crater of
#Agung related to the activity of effusion (flow) lava. The thermal energy has decreased since 28 June but it is still high. 6/1 odpowiedź 3 podane dalej 6 polubionychPokaż ten wątek -
#Agung is still in a phase of eruption. Currently, the eruption is generally effusive in the form of lava flows that fill the crater and explosive in form of incandescent rocks thrown around the crater & the eruption of ash. 7/1 odpowiedź 4 podane dalej 8 polubionychPokaż ten wątek -
The possibility of crater filling with lava material in a short time is low because the rate of lava effusion is still low.
#Agung's activities are still developing & unstable, & the possibility of eruption (effusive and explosive) is still high. 8/1 odpowiedź 4 podane dalej 9 polubionychPokaż ten wątek -
#Agung Hazards: ballistic hot rocks around the crater, ashfall further from the crater (depending on wind direction), low threat of lava flows outside the crater, low threat of pyroclastic flows. Threat of lahars in river valleys. These may change. 9/1 odpowiedź 8 podanych dalej 12 polubionychPokaż ten wątek -
#Agung remains on Alert Level 3 (out of 4). The hazard zone is a 4 km radius around the crater. This zone is dynamic and may change with changes in activity.

W odpowiedzi do @janinekrippner @id_magma
Would it be correct to expect that all of that accumulation within the 3-month stretch of high activity last year is now ready to be expelled?

We cannot really 'expect' anything. This system is too dynamic.

Right..
So "anything" can happen, right?

W odpowiedzi do @kopiganja @id_magma
Not anything, but there is a range of activity that Agung can produce based on what kind of magma it produces.

Do we know what that range is now?
