Research has found evidence in NSW for one the most devastating series of volcanic eruptions known.
Climate change doesn’t just affect the atmosphere and the oceans, it affects the Earth’s crust as well.

Tsunamis can be generated by underwater volcanic explosions thousands of miles away. The Jan. 15 explosion in Tonga resulted in tsunami advisories for British Columbia and all along the U.S. west coast.

The eruption is akin to a weapons-grade chemical explosion, and there could be several weeks or even years of major volcanic unrest to follow.

Volcanoes might seem like nature’s incinerators, but using them to burn up trash would be dangerous and disrespectful to indigenous people who view them as sacred.
The eruption in East Java that claimed 22 lives on Saturday was likely triggered by weather conditions rather than by internal unrest inside Mount Semeru, which would have been easier to monitor.
Greenland’s conditions were once similar to those of a greenhouse. Volcanoes swelled the land, constricted seaways and gigatonnes of greenhouse gases were released into the atmosphere.
The eruption of Krakatoa in 1883 sent volcanic dust and gases circling the Earth, creating spectacular sunsets captured by artists.

The Rev. Sereno Edwards Bishop mobilized ship captains to track the extraordinary sunsets appearing around the world after Krakatau erupted in 1883.
This isn’t a painting or a stained-glass window — it’s a microscope image of light shining through the Earth’s mantle.
I look at fragments of the Earth’s mantle under a microscope to learn how fast molten rock moves from deep in the Earth to the surface. This can help us prepare for future volcanic eruptions.

The eruption prompted the evacuation of about 20,000 people, with no casualties.
4 billion years ago, the Earth was composed of a series of magma oceans hundreds of kilometres deep.
The rocks provide rare evidence of a time when Earth’s surface was a deep sea of incandescent magma.

Charges regarding last year’s fatal Whakaari/White Island eruption should not be about blame, but about improving hazard warnings and enforcement, particularly for sites with a history of eruptions.
New Zealand has several volcanic areas that remain popular tourist destinations. A new early-alert system for eruptions would help operators determine when it is safe to visit an active volcano.
New research confirms that massive plumes of buoyant hot rock once rose from near the Earth’s core to the surface and triggered vast volcanic eruptions - and that New Zealand sits on top of one.
Located on the Ring of Fire, Indonesia is prone to natural disasters, particularly earthquakes, volcanic eruptions and tsunamis.
What is political will or political commitment to disaster risk reduction? Why is it important to measure political commitment? And how to measure it?

The tragedy at Whakaari/White Island highlights the need for consent forms to ensure tourists are fully informed when choosing to visit dangerous locations.
The sudden eruption at White Island was short-lived but produced an ash plume that rose several kilometres above the vent.
Five people have died and several remain unaccounted for after a sudden volcanic eruption on Whakaari/White Island off the east coast of New Zealand.
Rapid and voluminous volcanic eruptions around 252 million years ago can be linked with a mass extinction event.
There is evidence for catastrophic climate change from protracted volcanic eruptions in the past, but since the 1950s the emissions we produce far exceed those from volcanic activity.
