Often volcanic islands are not very stable. The fatal tsunami hit the coastal cities between 31 and 57 minutes after the slide. The fatal tsunami hit the coastal cities between 31 and 57 minutes after the slide. Therefore, a collapse of volcanic flanks occurs again and again, but so far missing detailed measurements of such events. The new research, led by Mohammad Heidarzadeh, an assistant professor of civil engineering at Brunel University, shows the disaster could have been much worse had the Indonesian coast been situated closer to the Anak Krakatoa volcano. Rebecca Williams from Hull University, UK, and colleagues have gone back and examined the satellite radar images that were taken of Anak Krakatau ("Child of Krakatau") before, during and after the volcanic activity that precipitated the flank failure. "I would challenge that the models are currently underestimating the ability of these landslides to make these larger tsunamis," she said. Often volcanic islands are not very stable. "The volcano has been almost permanently active since the 1940s," he says. Now researchers are showing how to warn of such catastrophes. The wave’s length was estimated to be between 1.5 to 2 kilometers (0.9 to 1.2 miles). "At the Krakatau we were able to observe for the first time exactly how the demolition of such a volcanic flank took place and which signals it announced," says volcanologist Walter.

But to identify the approximately two-minute slide itself in the measurements, the researchers had to look very closely, because it revealed in an unfamiliar seismic pattern. Looking ahead, Heidarzadeh has plans to work with the Indonesian Institute of Sciences (LIPI) and the Agency for the Assessment and Application of Technology (BPPT) to develop a new tsunami response plan for the region. They only disappear in subsequent days. Their needles hit 115 seconds before the collapse - probably caused by a small earthquake. Synthetic aperture radar and broadband seismic observations demonstrate that a small, <~0.2 km3 landslide on the southwestern flank of the actively erupting volcano Anak Krakatau generated the tsunami.

These projections turned out to be tragically accurate. This eruption, the 2 nd largest in Indonesia during historical time, caused more than 36 000 fatalities, most as a result of devastating tsunamis that swept the adjacent coastlines of Sumatra and Java.

In total, 430 people were killed, 14,000 injured and over 30,000 lost to their homes.

Researchers led by Thomas Walter from the German Geo Research Center in Potsdam (GFZ) have reconstructed the course of the disaster in a new study.

The results have now been published in the journal "Nature Communications". According to the investigation, the collapse was preceded by warning signals. Their needles hit 115 seconds before the collapse - probably caused by a small earthquake.

Anak Krakatoa has a history of inflicting misery. The Anak Krakatau is located in one of the most geologically active areas of the world. On December 22, the situation got worse. For this, existing measurement methods would have to be supplemented by additional sensors and new algorithms, according to the researchers. Dr Williams' team now think the flank collapse may have reorganised the plumbing of the volcano, opening a new vent that brought magma directly into contact with seawater.

The eruption of Anak Krakatoa in 2018 produced a tsunami that, for a short while, was somewhere between 330 to 492 feet tall, according to new research. "At the Krakatau we were able to observe for the first time exactly how the demolition of such a volcanic flank took place and which signals it announced," says volcanologist Walter.

When Anak Krakatoa erupted on December 22, 2018, it caused a landslide that triggered a dangerous tsunami in Indonesia’s Sunda Strait.

The dramatic images from Indonesia are unforgettable: on December 22 of last year, a tsunami devastated the coasts of the islands of Sumatra and Java. Rather, a huge landslide was responsible, as flanks of the island volcano Anak Krakatau collapsed. This is a third of the volume that had been anticipated would produce the kind of tsunami witnessed on 22 December. More than a million cubic meters of earth slipped into the sea, they set the fatal tidal waves in motion. Huge explosions then removed the summit, (4) The volcano began to rebuild itself and closed off the underwater vent. Hence the name Anak Krakatoa, which means “Child of Krakatoa.”. Vivid new satellite photos of Anak Krakatau are providing our first cloud-free glimpse of the…. "Over the following weeks, as the volcano started to build again, the water was eventually stopped from getting into the magmatic system and Anak Krakatau went 'back to normal'.
