The volcano is behind the tsunami in Indonesia

Anak Krakatoa young volcano rises from the sea and grows to an altitude of more than 300 meters in less than 100 years due to continuous spraying of lava.

Anak Krakatoa, the volcano caused on December 22, emerged from the sea 90 years ago and is always in the list of intense eruptions over the past decade, according to SCMP.

Anak Krakatoa (meaning "Child of Krakatoa") has been operating since June, frequently spraying in October. Experts say Anak Krakatoa appeared in 1928 in the hollow of the pan of Krakatoa, the volcanic island once erupted. In 1883. With continuous lava flows, Anak Krakatoa grew from an undersea soil to a small volcanic island with a tip at an altitude of about 305 meters above sea level.

Since its inception, Anak Krakatoa has been in "semi-continuous operation" , becoming bigger when the 2-3 years have erupted, according to volcanic professor Ray Cas at Monash University, Australia. "Most of the relatively small eruptions follow the scale of eruption and there are also events that create lava bombs , " Cas said.

According to Cas, the latest event seems to be "a relatively small eruption" but can be triggered or coincide with an undersea event such as landslides or earthquakes, causing a tsunami disaster. There are no people living on the island, but the peak of the mountain attracts many tourists and is an important area for studying volcanoes.

When erupting on August 27, 1883, Krakatoa erupted a ash column over 20km high in a series of explosions that could be heard in Australia and ranged 4,500km near Mauritius. The giant ash cloud makes the whole area in darkness for two days. Dust created beautiful sunsets and sunsets around the world throughout the following year and disrupted the weather pattern for many years. The tsunami triggered by the eruption killed more than 36,000 people, marking one of the worst natural disasters.

Indonesia is located near the intersection of three continental plates that constantly push each other under enormous pressure so it is particularly prone to earthquakes and volcanic eruptions. This island has nearly 130 active volcanoes, forming part of the "Ring of Fire" , a horseshoe that focuses on intense seismic activity stretching from Japan to Southeast Asia and surrounding the Thai Binh basin.
