The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has urged the public to remain calm amid the status of Mount Anak Krakatau, which is currently at Level III or Alert (Siaga). Although intensive volcanic activity has been observed, geological authorities emphasized that the volcano's current condition is not similar to the sequence of events that triggered the Sunda Strait tsunami disaster in late 2018.
Deny Mardiono, a volcano observer from the Anak Krakatau Volcano Observation Post, explained that seismic activity is dominated by volcanic earthquakes with energy levels that remain low. Based on monitoring data up to July 8, 2026, eruptions produced ash columns between 100 and 250 meters high, but eruption materials are confirmed to be still concentrated around the volcano's body and have not reached residential areas.
Furthermore, Deny addressed public concerns regarding the tectonic earthquake that recently shook the Sumur area in Pandeglang. According to him, this seismic phenomenon has no direct connection with the fluctuations of magma activity in the Anak Krakatau crater. Additionally, he emphasized that the energy currently being released is gradual and far smaller than the accumulation of energy that caused the collapse of the volcano's body in 2018.
As a precautionary measure, PVMBG has established an exclusion zone within a three-kilometer radius of the active crater. The public and tourists are requested not to approach or land in the area for safety reasons. In addition to the access restriction, authorities continue to educate coastal residents to reduce trauma and improve literacy regarding the unique characteristics of each volcanic eruption phase.
The public is expected to refer only to official information channels from the local government, BPBD, or PVMBG to avoid misinformation from unreliable sources. Mitigation efforts remain the top priority to ensure the safety of residents along the Sunda Strait coast while continuously monitoring the situation periodically.
