2018 Sunda Strait tsunami
tsunami in coastal regions of Banten and Lampung, Indonesia
The 2018 Sunda Strait tsunami (Indonesian: Tsunami Selat Sunda 2018) occurred on 22 December 2018 at around 21:38 local time after large parts of the southwestern side of Anak Krakatoa collapsed onto its caldera. The landslide spawned a tsunami wave that struck multiple coastal regions in Banten and Lampung, including the tourist destination of Anyer.
Lack of warnings on the arrival of the tsunami, coinciding with the Christmas and New Year holiday season in the nation and the tsunami occurring at nighttime, contributed to the large loss of life. With 426 deaths, the tsunami was the deadliest volcanic tsunami in Indonesia since the 1883 Krakatoa tsunami, which originated from the same island.
Following the tsunami, Indonesian authorities installed multiple emergency early warning systems in tsunami-prone areas. The newer system would detect any significant disturbances on water levels, including changes caused by volcanic activity or undersea landslide.
Background
Lying on the Ring of Fire, Indonesia experiences frequent earthquakes and is home to 127 active volcanoes. One such volcano is Krakatoa in the Sunda Strait. The volcano was famous for its historic eruption in 1883, one of the most violent eruptions in recorded history. That eruption, through tsunamis and ash fall, killed more than 36,000 people, many of whom lived in the same regions where the 2018 tsunami struck.

Why this record matters
“2018 Sunda Strait tsunami” is worth following because a concise public description often conceals a longer documentary argument. Here, Sunda, Strait and tsunami provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q60042839. Authority coordinates are -6.103, 105.423. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2018 and 1883.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
