JAKARTA - The public and of course citizens were shocked by the natural phenomenon that emerged from Mount Anak Krakatau, located in Lampung. Not a few of them heard a boom that was claimed to be the eruption of the volcano.

The National Institute of Aeronautics and Space (LAPAN) of the Republic of Indonesia, through its official Instagram account @lapan_ri, said that the booms heard in the Jabodetabek area did not come from an eruption of Mount Anak Krakatau.

LAPAN's main expert researcher, Prof. Dony Kushardono, gave his observations through monitoring of LAPAN's weather satellite imagery (visible & infrared). Monitoring shows the difference in the timing of the eruption of Anak Krakatau and the timing of the explosion that occurred in the area.

The upload also includes a video, in which volcanic eruptions appear from the mountain at 24.00 WIB. There were also clouds of dark gray smoke that appeared enveloping the surrounding area and dust that flew in the wind towards the west until 05.00 WIB.

"So, the sound of crashing heard in Jakarta-Depok which was rumored to have occurred at around 02.00 in the morning was probably not the sound of the eruption of Mount Anak Krakatau," wrote @lapan_ri in his Instagram post.

The head of LAPAN, Thomas Djamaluddin, revealed the same thing. He stated that the boom also did not come from natural or celestial phenomena. Even the LAPAN facility cannot claim this.

"I do not know about the explosion. The LAPAN facility is not involved in detecting the claims of the explosion," said Thomas when contacted by the VOI team, Saturday, April 11.

Meanwhile, many netizens on the Twitter social media network said that this boom was a skyquake phenomenon. However, this phenomenon has no scientific and proven explanation. I have no idea. What is clear, skyquake itself is an interesting phenomenon that has long been a mystery.

what if the sound this morning was a skyquake? the ozone layer is fragile again due to reduced activity on earth? 🤔

Skyquake

As reported by Science How Stuff Work, skyquakes are often touted as a boom that comes from the sky, as well as a falling meteor. The sound was similar to that of cannons and other large explosions crashing to the ground.

The sound of skyquakes has been heard several times in the United States (US), India, where the seaside cities of Digha and Mandarmani heard explosions so loud that they destroyed hotel windows. Likewise with Japan and Australia in the past.

According to United States Geological Survey (USGS) Scientists, Emeritus David Hill revealed that mysterious explosions had been heard for years in various parts of the world. In Belgium, skyquakes are known as 'liars' while Italians call them 'bronties.'

Residents around Seneca Lake in New York's Catskill Mountains, residents have long heard of the "Seneca guns," a phenomenon that writer James Fenimore Cooper described in 1851 as sounding like the explosion of a piece of heavy artillery, which could not be explained by natural law until now.

Thumping sounds can also occur due to shallow earthquakes that can produce sounds that can be heard without shaking. The explosion of methane gas released from the methane hydrate can also be a factor in the explosion. Or a meteor falling from the sky.

As Hill wrote, meteors that penetrate the atmosphere can create sonic waves that will not reach the Earth's surface until after the meteor has disappeared, so that the relationship between the two is not visible to the naked eye.

"It is true that there may be some plausible explanation for any particular occurrence of the mysterious explosive sound, and that the environment in which the sound is heard will determine which of the possible explanations makes the most sense. The sound heard in the middle of the desert, for example, could not have been caused by the breaking waves, "said Hill.

Hill added that most of the booming sound was heard within a limited range, so reports of a collection of boom sounds separated by a distance are likely to come from multiple sources. This may include the sound of a meteorite exploding in the atmosphere high above Earth or an airplane flying at supersonic speeds over a longer distance.
