As reported Jakarta Post,some Internet users in a Large Jakarta said they heard a loud rumble before the reports of the eruptions of the volcano. The authorities, however, questioned this assumption, stating that the eruption could not even be heard from the observation post of the Anak-Krakatau.
«[Loud rumbling] may not be associated with the eruption», — said the head of PVMBG Cassani.
People who live near the volcano in Buntine and Lampung, also tweeted that heard nothing.
Expert on Volcanology of Surono, however, suggested that the users of the network in Big Jakarta may be right.
The sound caused by the eruption, could impact throughout greater Jakarta, as in this area there is less activity and noise as a result of widespread social restrictions associated with COVID-19, he said.

In Lampung BPBD reported no smell of sulphur or rain of volcanic ash in the region and warned local residents that volcanic activity at Anak-Krakatau stopped.
«BPBD contacted the group of observers of Anak-Krakatau. They said that the status of the volcano is still «alarming», but volcanic activity has ceased, therefore residents are advised not to panic «, said agus.
Military and police are in standby mode, together with officials of the villages and districts in connection with the possible evacuation of residents.
Cassani said the eruption was relatively small compared to eruptions that occurred in the period from December 2018 to January 2019.
«[The eruption] is still within the expected level. Potential eruption could occur but was not detected in volcanic activity that could lead to the strengthening of their intensity», said Cassani.
Rahmatullah, a resident of the island Sebesi, located 19 kilometers from the volcano, reported that the island began to fall thick ash.
«Thick ash began to fall at midnight. He’s still lying in front of my house», said Rahmat, adding that the residents living on the coastline, were evacuated after the warnings of officials.
The last major eruption occurred in December of last year, when the volcano threw a column of ash height of 200 meters. This led to a tsunami in which at least 430 people were killed, more than 1400 were injured.
After the eruption on Friday, the residents of the coastline of Kalianda in South Lampung was also evacuated for fear that a tsunami could happen again.
«They immediately fled to the mountains, because I remember well the consequences of the previous tsunami», — said the resident of South Lampung Umar.
Surono said that now a tsunami less likely because of the tsunami in 2018 was caused by soil erosion as a result of years of eruptions.
He said that the eruption of the Anak-Krakatau, have become commonplace.
«At one point, the mountain continuously erupted for years, but now the residents are more afraid of the tsunami».
Anak-Krakatau, which means «the Child of Cretaceou», is a volcanic island that emerged in 1927.
The volcano of Krakatoa (1883)
The eruption of Krakatoa occurred on Sunday, 26 August 1883. The next day at 10:20 a giant explosion tore apart the volcanic cones of Danan and Perbuatan. The roar of the explosion was heard in Australia, at a distance of 3600 km, and Rodrigues island in the Indian ocean, a remote, nearly 5000 km.
The explosion lifted into the air more than 18 cubic km of rocks. Ash fell on an area of about 827 000 sq. km. In Jakarta, the main city of the island of Java, he darkened the Sun to such an extent that it was almost full dark. The finest dust reached the stratosphere of the Earth and spread across the globe, provoking unusual twilight in all countries of the world. Ash lowered global surface temperature by 1 degree Celsius.
A terrible explosion caused a tsunami up to 40 m, killing 36 000 people. Even in the English channel between Britain and France, the instruments recorded an increase in tide height.
On a scale Hedervari (P. Hedervari, 1963), the eruption of Krakatoa in 1883 is estimated at magnitude 9.54 points. It is equivalent to the explosion of 21 547 atomic bombs.
