The 1883 Krakatoa Eruption: Impacts Felt Across Multiple Nations

Anak Krakatau, located in the waters of the Sunda Strait, has been experiencing continuous eruptions. This volcanic activity has been ongoing from the night of Friday, 4 September 2026, through Saturday, and continues as of the latest monitoring period.

The eruption of Anak Krakatau has also drawn the attention of the Japan Meteorological Agency (JMA). In its report, the JMA stated it detected tremors from a distance at 04:00 local time, or approximately 02:00 WIB. Based on monitoring results, the JMA stated that the eruption of Anak Krakau does not have the potential to cause a tsunami that would impact Japan.

“No significant changes in sea level were observed at monitoring stations in Japan or abroad,” stated the JMA, as reported by The Nation on Sunday, 6 September 2026.

JMA’s monitoring of Anak Krakatau’s activity has also been highlighted by a senior researcher from the Centre for Climate and Atmosphere Research at the National Research and Innovation Agency (BRIN), Prof. Dr. Erma Yulihastin. According to her, the world’s attention towards the eruption of Anak Krakatau is inseparable from the history of the massive Krakatoa eruption in 1883.

“Krakatoa was once a global nightmare. When Krakatoa erupted in 1883, almost the entire world felt the impact. The world was dark for days. Countries in the Northern Hemisphere lost their winter. That is why this eruption of Anak Krakatau is certainly receiving global attention,” she wrote on her personal X account @EYulihastin, as quoted on Sunday, 6 September 2026.

So, how devastating was the Krakatoa eruption of 1883 that it became one of the volcanic events receiving worldwide attention? The eruption of Mount Krakatoa in 1883 was one of the most powerful volcanic eruptions and caused one of the greatest impacts in human history. The eruption of the volcano located on Rakata Island even became a headline in news reports across the globe.

According to the official website of the Britannica encyclopedia, Britannica.com, on Sunday, 6 September 2026, Mount Krakatoa is located in the meeting zone of the India-Australia and Eurasia tectonic plates, known as a region with high volcanic and earthquake activity. Over the last one million years, this mountain has formed a volcanic cone composed of alternating flows of volcanic rock with layers of volcanic gravel and ash. From the base of the mountain, which lies approximately 300 metres below sea level, the cone rises to about 1,800 metres above sea level.
