|Tonga volcano eruption was a record explosion
A team of scientists has said the volcano that erupted under the sea near Tonga in January set a record. The Tonga-Hunga Ha'apai volcano erupted on January the 15th. It was the biggest explosion ever recorded using modern instruments and technology. It was also the biggest to happen in the past 150 years. The scientists said the blast may have been as large as the Krakatoa eruption that took place in Indonesia in 1883. Dr Robin Matoza from the University of California said: "Tonga was a truly global event, just as Krakatoa was. But we've now got all these geo-physical [recording] systems, and they recorded something that was really [unmatched] in the modern data."
