É óbvio... quando se referem a erupção é a uma grande erupção como a de 63. O problema são as traduções.

The seismic activity this morning local time is confirmed to be quakes. Aka. heavy shaking that made people flee the area. Reported in my native language norwegien based on an article in Bali Express now.

12.05pm: Larger eruption may be "imminent"
The latest BNPB statement said: “Continuing plumes of smoke are occasionally accompanied by explosive eruptions and the sound of weak blasts that can be heard up to 12 km (seven miles) from the peak.
“Rays of fire are increasingly visible from night to the following day. This indicates the potential for a larger eruption is imminent.”

12.25pm: Explosions throw out molten rock and ash
David Pyle, a volcano expert at the University of Oxford, said: "It remains possible that the eruptive crisis could continue for some time."
He added: "What we are seeing at the moment are small explosions, throwing out hot gases and fragments of molten rock, or ash."

2.45pm: Terrifying satellite imagery shows sulphur dioxide spread over Bali
High concentrations of toxic sulphur dioxide have been leaking from Mount Agung’s crater and into the atmosphere, Nasa’s Aura satellite revealed.
The NOAA National Environmental Satellite, Data and Information Service tweeted: “Data from @NASA Aura satellite shows high SO2 concentrations from Mount #Agung yesterday in #Bali, #Indonesia.
“People on the ground witnessing the #volcano emitting thick ash clouds and glowing lava.”
The volcanic compouds has mostly spread to the north and south away from Bali, but individual SO2 clouds have reached the island of Java.

This interferogram (no exact date, but 2017) shows that the most distortion has been on the north side of Agung. Each cycle of rainbow colors represents another 2,8cm of movement. I count something like 13 cycles of color up the north slope.
If there is rim failure and a spill down one side, I expect it will be to the North. If the rim holds, the low side of the rim is now on the south side. So that is the effective spillway, at the moment.

3.49pm: ‘Bigger eruption is coming’ warns expert
Professor Peter Sammonds, of UCL, warned that all of the signs coming from mount Agung, suggest that a bigger eruption is on its way.
He told Sky news: “The indications are that this eruption has been building through the phases of, first of all, seismicity, small earthquakes, then ash, then some lava and this indicates that this will build into something of a major nature.”

4.48pm: Mount Agung could explode ‘in hours’ warns volcanologist
Mount Agung could be on the brink of violently exploding Indonesian volcanologist Gede Suantika has warned, accordging to The Herald Sun.
A massive 30-minute tremor deep inside Agung’s crater could be sign of lava trying to breach to the surface,
He said: “It means there is a quite big amount of volcanic material that will come out.
“There are two possibilities of how it will come out. First, the magma will fill the crater and flow out or it will come out as an explosion.
“Now the magma flow is continuous. I am just scare that this will happen soon and come out at once in a big explosion.”
He added: “Soon — I cannot be sure. But maybe in hours, not days, because it’s already erupting. We are just waiting for the big one.”

VIRAL: Fish and eels come flopping downstream of smoking Bali volcano 2/43
New Deputy Governor for BNM
Hundreds of fish and eels were spotted coming down Bali’s Unda River on Tuesday, downstream of the island’s smoking Mount Agung volcano.
The volcano has been belching thick gray clouds of since last week and in the last few days has been shooting up plumes of ash into the sky, leading to the volcano getting upgraded to the highest alert status since Monday.
Photos posted to Facebook by Ary Kencana show residents holding up various types of fish and eels on Tuesday in the muddied Unda River in Bali’s Klungkung regency, which is south of Karangasem where the volcano is.
The fish were “already dead” and “killed because of nature,” wrote Kencana, who added that hundreds of people had come to the Unda around 9am to take the fish.
“Because the water from the river mixed with mud and volcanic ash,” she wrote.
This phenomenon also happened in 1963, according to old people in Bali

5.33pm: Raging tropical cyclone is shifting Mount Agung’s ash cloud
Indonesian officials said that cyclone Cempaka, located hundreds of miles west of Bali, has begun to affect Agung’s ash emissions.
The churning cyclone pulling in the dangerous ash cloud, out towards the open Indian Ocean.
On top of the erupting volcano, cyclone Cempaka threatens to slam into the Indonesian islands.
Cempaka is expected bring in heavy rain, devastating waves and strong winds up to 30 knots per hour for three to four days.

Magma movement in Askja volcano (Dyngjufjöll)
Posted on November 28, 2017 by Jón Frímann
For the past few days there has been a earthquake activity in Askja volcano. All of the earthquakes so far have been small in magnitude and only few have reached magnitude above 1,0. This earthquake activity is due to magma movements and its the first time I have seen it reported at this shallow depth (above 10 km depth).
Earthquake activity in Askja volcano. North of Vatnajökull glacier. There is also activity in Herðubreið to the east, but that’s an unrelated activity and is due to tectonic forces in the area.
There are no clear signs that an eruption is about to happen in Askja volcano or in Dyngjufjöll as this area is also called. If an eruption starts in this area outside of any major water area its only going to erupt lava with minimal risk. Explosive eruption due to water is also a possibility but those are impossible to predict.
