When the Hunga Tonga-Hunga Ha'apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in the South Pacific Ocean also blasted an enormous plume of water vapor into Earth's stratosphere - enough to fill more than 58,000 Olympic-size swimming pools. The sheer amount of water vapor could be enough to temporarily affect Earth's global average temperature.

The Center for Volcanology and Geological Hazard Mitigation (PVMBG) official Oktory Prambada said the eruption was not caused by magma movement activity. "It happened in 540 seconds," he said to Tempo on Thursday, July 28, 2022
According to him, the ash column was not dense which indicated that the eruption occurred only on the surface, and it was considered a small eruption. "It's just a release of energy or degassing," he added.
A volcano on Japan's major western island of Kyushu, called Sakurajima, erupted at about 8:05 p.m. (1105 GMT) on Sunday, the Japanese Meteorological Agency (JMA) said, but media said there were no immediate reports of damage.
There were reports of volanic stones raining down at a distance of 2.5 km (1.5 miles) from the volcano, NHK public television said. The eruption alert level has been raised to 5, the highest, with some areas advised to evacuate, it added.
Sakurajima is one of Japan's most active volcanoes and eruptions of varying levels take place on a regular basis. In 2019 it spewed ash 5.5 km (3.4 miles) high.
A pillar of smoke and ash was expelled to a height of nearly 3 kilometers.
Lava bombs were emitted into the surrounding area by the eruption.
Warnings are in place for ash fall in the surrounding area for the coming days.
Flights are on alert with the smoke set to affect plane travel.
Citizens have been advised to remain clear of the volcano during this period.

Meanwhile, in the Philippines, the Phivolcs disaster agency released a special warning regarding the Kanlaon volcano. And, in Alaska, two volcanoes which have each not erupted in about a century produced a several thousand foot tall plume of ash.
This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.
