The graph provides minute-by-minute updates on all seismic activity surrounding the volcano on the website of MAGMA Indonesia which gives official updates on the volcano.
Mount Agung has stabilised slightly over the past few days, according to Indonesia’s Center for Volcanology and Geological Disaster Mitigation (PVMBG).
“Based on the record of the monitoring post, the number of tremors has dropped,” PVMBG spokesperson Gede Suantika said on Monday.
Despite the decrease in the number of tremors, Bali remains under the highest volcano alert because volcanic activity is still dangerously high.
How to read a seismogram
Seismograms can appear daunting at first glance, but they are vitally important to the work of volcanologists.

Produced by the United States Geological Survey (USGS), the video tutorial above breaks down how to read the data.
Any large blue plots indicate when a tremor has occurred, with wider plots representing more powerful quakes.
Seismograms are then used to determine the magnitude of each earthquake. Each horizontal line on the graph equates to 30 minutes in real time.
What is happening in Bali?
With the chance of an eruption increasing, Bali governor I Made Mangku Pastika has declared a state of emergency on the island.
More than 140,000 evacuees decided to leave their homes to escape the looming threat of Mount Agung. But about 70,000 people were told to return because they were not within the danger zone.
Mount Agung has not erupted since 1963, when it killed more than 1,100 people and injured 300 more.
Bali sits on the deadly Pacific Ring of Fire – the most active earthquake belt on the planet. It is thought that as much as 90 per cent of the world’s earthquakes occur along the belt.
