[UPDATED 2021] What You Need to Know About the Hunga Volcano Eruption: A First-Hand Account with Essential Tips and Stats for Travelers [Expert Guide]

What is hunga volcano eruption?

Hunga volcano eruption is a volcanic activity that occurred in January 2015 on the uninhabited Hunga Tonga-Hunga Ha’apai island, located between Tonga and Fiji. The eruption was caused by an undersea explosion that created a new island measuring about one kilometer long and more than 100 meters wide.

Must-know facts about this event include the fact that it was visible from space and classified as a submarine eruption due to its underwater explosion origins. Additionally, surrounding countries and neighboring islands such as Fiji were put on alert for potential tsunami waves after the eruption occurred.

Explained: Step-by-Step of the Hunga Volcano Eruption

On March 19th, 2021, the Hunga Tonga-Hunga Ha’apai volcano erupted in the South Pacific Ocean. This event was captured by satellites and witnessed by vessels in the area. The eruption started off as a fissure eruption, which is a type of volcanic activity where molten rock or magma flows out from beneath the Earth’s surface through a long crack or fissure. In this case, the magma flow was triggered by tectonic plate activity in the region.

Step One: Fissure Eruption
The initial stage of the Hunga Tonga-Hunga Ha’apai eruption involved magma coming to the surface via a fissure that opened up on one side of an undersea volcano. This resulted in lava slowly pouring out of the crack and building up a new island over time.

Step Two: Steam Explosions
As water seeped down into cracks caused by this newly formed island, it quickly vaporized and created steam explosions that hurled large rocks and other debris into the air.

Step Three: Ash Clouds
As this explosion continued, ash clouds formed and dispersed across different areas over time. These clouds may continue to drift thousands of kilometers across nearby islands due to high winds – posing dangers for commercial airlines if not properly alerted.

Step Four: Pyroclastic Flows
Pyroclastic flows occur when superheated gas, ash, and rock explosively shoot out of a volcano at incredibly high speeds – descending down steep slopes at speeds so fast they can easily wipe-out anything in their path.

Overall Impacts & Importance
This kind of event highlights how volcanoes work naturally – which helps understand larger-scale land formations upon which humans are dependent for farming or geothermal energy production locally even globally. It also highlights support needed for early warning systems with geologists advising on safe evacuation procedures necessary for populations living nearby due to potential hazards that may occur if future eruptions happen nearby.
