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.
On Jan. 15, 2022, coastal areas across California were placed under a tsunami warning.

Tsunamis aren’t just bigger-than-average waves. Triggered by undersea earthquakes or volcanic eruptions like the one in Tonga, they are fast, massive and potentially destructive. Here’s why.

Australians tend to be fairly relaxed about the tsunami risk. But warnings from authorities to stay away from foreshore areas should not be ignored.

People tell tales to explain what they see – centuries later, scientists try to map handed-down myths onto real geological events.
In the immediate aftermath of an event like the 2004 Indian Ocean tsunami, the path forward is not always clear. Looking backward, what have we learned?
Three weeks after the 9.0 magnitude quakre and subsequent tsunami struck Japan.
Japan has a long experience of hazards and disasters. Yet it does not seem like all lessons have been applied when it comes to COVID.

Indonesia has a warning system for tsunamis generated by earthquakes – but not volcanoes.

Massive landslides can trigger destructive and deadly tsunamis, and climate change could make them worse.
Eco-fiction to help you rethink your role in the climate crisis.
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?
This unusual earthquake type generates an outsized tsunami.
A tricky kind of earthquake that happens in the soft rock of the ocean floor causes much larger tsunamis than their magnitude would predict. New research pinpoints a way to identify the danger fast.

A devastating quake and tsunami in the Pacific Ocean prompted a new kind of post-disaster research. Ten years on, we need these lessons to prepare for a precarious future.
Half the deaths from Atlantic hurricanes are down to storm surge. People in vulnerable regions need to be aware of what it is and how it threatens their safety.
The quake prompted several buildings to be evacuated in central Darwin.
Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.
Waves can be generated in lakes and other bodies of water when seismic energy travels through land.

If you’ve never heard of a form of wave called a ‘seiche’ – which can occur in swimming pools during earthquakes – this is your chance to catch up.

Research into volcanic activity in the waters off Indonesia shows how active this region is and how destructive landslide-caused tsunamis can be.

Making the word smong part of the Indonesian vocabulary does not mean removing the word tsunami. Smong should be a source of pride in how local knowledge protects us from disaster.

Earthquakes and tsunami in Indonesia this year did not only leave a deep sorrow. It made us rethink the relationship between humans, technology and nature in Indonesia.
In this Oct. 10, 2018, photo, a man walks past a boat swept ashore by a tsunami in Wani village on the outskirt of Palu, Central Sulawesi, Indonesia. The 7.5 magnitude earthquake on Sept. 28, triggered a tsunami and mudslides.

Last month’s earthquake in Sulawesi, Indonesia was large, but not huge. It was the aftereffects that made it so devastating.
Manly’s The Corso pedestrian area could be flooded if a large tsunami arrived at Sydney Harbour.
To stay safe in a tsunami, remember that the sequence of waves may occur over hours to days, and the biggest wave in the sequence could occur at any time.
