20 years after the greatest natural disaster in modern history, could it happen again?

It has been twenty years since a massive earthquake and subsequent tsunami devastated communities in Southeast Asia, resulting in nearly 230,000 deaths and millions displaced in the worst natural disaster in modern history.

On the morning of December 26, 2004, a magnitude 9.2 earthquake struck the seabed off Indonesia, triggering a wave of water up to 30 meters high that moved toward communities around the Indian Ocean.

It is the strongest earthquake in Asia, the largest earthquake in the world in the 21st century, and the third largest since 1900.

The length of the plate separation was between 1200 and 1300 kilometers, which is why the earthquake was felt even in remote Alaska.

Indonesia, Sri Lanka, India and Thailand were the hardest hit, with water wiping entire villages and towns from the map. The tsunami reached nine other countries.

Survivors faced isolation and illness in the days that followed as initial rescue and relief efforts were hampered by physical resources due to the scale of the disaster.

At the time, US President George W. Bush declared that the scale of the losses was beyond reason, while several governments were accused of delaying an emergency response.

In the years following the disaster, the international community raised more than $13 billion in donations, the largest humanitarian response to any natural disaster.

Researchers who have studied the region and visited areas affected by the tsunami say that signs of the disaster are still present decades later.

Experts noted that the affected regions still lag behind economically compared to areas that were not affected by the tsunami and many survivors are still living with post-traumatic stress.

What caused the earthquake and could it happen again?

According to the US National Geological Survey, the historic earthquake was caused by the subduction of the Indo-Australian tectonic plate under the Eurasian plate.

The region, also known as the Sunda Trench, is highly seismic and has produced several earthquakes with magnitudes greater than 7 on the Richter scale since 2004.

Statistically, the occurrence of a magnitude 9 earthquake along a fault zone occurs no more often than once every several hundred to more than a thousand years. However, seismologists warn that the interval between such events can be very irregular.

The National Earthquake Information Center estimates that between 12,000 and 14,000 earthquakes occur worldwide each year, but only a small percentage are felt.

Earthquakes measuring eight or more on the Richter scale are considered "major earthquakes" and occur once every two years along thousands of fault zones around the world.
