Observation Status of Mount Agung still survive until today, Selada (5/12/2017), although the latter condition is relatively quiet,
On Monday (4/12/2017) yesterday, Mount Agung only issued a thin smoke. Seismic activity is also relatively quiet. Meanwhile, SO2 gas concentration dropped dramatically 20 times more than the eruption phase on 26-27 November 2017.
According to the Head of Information and Public Relations Data Center of National Disaster Management Agency (BNPB) Sutopo Purwo Nugroho, the condition at least reflects two possibilities.

First, the weakening magma rate rises to the surface.
KOMPAS.com/ESTU SURYOWATI Head of Information and Public Relations Data of BNPB Sutopo Purwo Nugroho in a press conference at BNPB office, Jakarta, Tuesday (05/12/2017). "This is because magma lost energy due to magmatic gas has diminished post-eruption yesterday , and eventually runs out of balance, which can end up with Gunung Agung continuing to sleep, "said Sutopo at BNPB office, Jakarta, Tuesday (5/12/2017).
The second possibility is blockage of the magma pipe.
The magma fluid that moves to the surface is blocked by the lava on the surface that cools and solidifies.

Sutopo said the accumulated blockages could lead to a bigger next explosion.
"The eruption of 1963, the second possibility is what happened, at the same time, two weeks stopped, then there was a bigger eruption," Sutopo said.Sutopo said the two possibilities are still being analyzed PVMBG. With the complexity possessed by volcanoes, the science of volcanology to date can not be approached by deterministic methods.
"The mountain has a 50:50 chance, although all instruments have been installed, PVMBG keeps monitoring Gunung Agung intensively," said Sutopo.
