9.1-magnitude quake caused a tsunami that smashed into coastal areas on December 26, 2004, killing more than 220,000 people
The world's deadliest tsunami hit nations around the Indian Ocean two decades ago before social media platforms flourished, but they have since transformed how we understand and respond to disasters -- from finding the missing to swift crowdfunding.
When a 9.1-magnitude quake caused a tsunami that smashed into coastal areas on December 26, 2004, killing more than 220,000 people, broadcasters, newspapers and wire agencies were the main media bringing news of the calamity to the world. Yet in some places, the sheer scale took days to emerge.
Survivor Mark Oberle was holidaying in Thailand's Phuket when the giant waves hit Patong beach and penned a blog post to fend off questions from family, friends, and strangers in the days after the disaster.
'The first hints of the extent were from European visitors who got text messages from friends back home,' said Oberle, adding people initially thought the quake was local and small, when its epicenter was actually near western Indonesia, hundreds of miles away.
'I wrote the blog because there were so many friends and family who wanted to know more. Plus I was getting many queries from strangers. People were desperate for good news tales,' said the US-based physician, who helped the injured.
The blog included images of cars plowed into hotels, water-filled roads and locals fleeing on scooters because rumours produced 'a stampede from the beach to higher ground'.
Bloggers were named 'People of the Year' by ABC News in 2004 because of the intimacy of first-hand accounts like those published in the days following the tsunami. But today billions can follow major events in real-time on social media, enabling citizen journalism and assistance from afar, despite the real risk of rumour and misinformation.
During Spain's worst floods for decades in October, people voluntarily managed social media accounts to assist relatives trying to locate their missing loved ones. After Turkey's devastating earthquake last year, a 20-year-old student was rescued thanks to a post of his location while buried under the rubble.
- 'Fast picture' - Two decades ago, the online social media landscape was vastly different. Facebook was launched early in 2004 but was not yet widely used when the tsunami hit. One of YouTube's founders reportedly said an inspiration for the platform's founding in early 2005 was an inability to find footage of the tsunami in its aftermath.
Some tsunami images were posted on photo site Flickr. But X, Instagram, and Bluesky now allow for instant sharing.
Experts are clear that more information saves lives -- hours lapsed between the tremor's epicenter near Indonesia and the giant waves that crashed into Sri Lanka, India, and Thailand's coastal areas.
Daniel Aldrich, a professor at Northeastern University, conducted interviews in India's Tamil Nadu where many said they had no idea what a tsunami was and had no warnings in 2004.
'In India alone, nearly 6,000 people were taken by surprise and drowned in that event,' he said. Mobile apps and online accounts now quickly publicise information about hospitals, evacuation routes, or shelters.
'Social media would have provided an immediate way to help locate other survivors and get information,' said Jeffrey Blevins, head of journalism at the University of Cincinnati. Oberle also noted that 'knowing what help was locally available... would have provided a clearer perspective of what to expect in the days to come'. - Citizen science - Beyond emergency rescue, social media clips can also be a boon to understanding a disaster's cause.
When giant waves crashed into Indonesia's Aceh province, footage remained largely confined to handheld camcorders capturing the carnage. Fast forward to 2018, when a quake-tsunami hit Indonesia's Palu city, killing more than 4,000 people, enough videos were taken on smartphones that scientists researching seismic activity were later able to use the clips to reconstruct its path and time between waves.
The piece of citizen science in 2020 used amateur videos to conclude it happened so fast because of underwater landslides close to shore. But it's not all good news. Scholars warn that disinformation and rumors have also hindered disaster responses. When Hurricane Helene struck North Carolina in September, relief efforts were disrupted as tensions between locals and emergency workers rose over unfounded rumours including a higher hidden death toll and diverted aid. Workers faced reported threats from local armed militias.
'This information was so malicious that FEMA (Federal Emergency Management Agency) had to withdraw its teams from the area,' said Aldrich. 'Social media has altered the field of disaster response for the good and the bad.' Yet perhaps the biggest change -- the free flow of information to the vulnerable -- has been beneficial. Laura Kong of the Honolulu-based International Tsunami Information Center recently recalls how '2004 was such a tragedy'. 'Because... we might have known there was an event, but we didn't have a way to tell anyone.'
Aceh
Traumatized by the Indian Ocean tsunami that hit Indonesia 20 years ago, Teuku Hafid Hududillah has spent his adult life making sure that if disaster strikes again, his home province of Aceh will be ready.
Hududillah was among those who lost many relatives when the tsunami struck on Dec. 26, 2004, killing 126,000 in Aceh, where no sirens were heard, resulting in the highest toll among the 230,000 dead along the coasts of more than a dozen countries.
The tsunami was triggered by a 9.1 magnitude earthquake off the island of Sumatra. Now a quake observer for Indonesia's geophysics agency, 28-year-old Hududillah is part of a team tasked with upgrading Aceh's quake detection and tsunami warning system, including sirens loud enough to be heard 100 km (62 miles) away.
'We think Aceh will be ready for evacuation if a tsunami occurs,' Hududillah said at one of the siren towers in the provincial capital of Banda Aceh, adding that he was thankful for the effort while hoping there would be no more disasters.
The system will quickly dispatch telephone and radio messages to notify residents of earthquakes of magnitude more than 5, he said, while the sirens will signal the likely risk of a tsunami. Indonesia, which straddles the seismically active area known as the Pacific Ring of Fire, is one of the world's most disaster-prone countries but has often been criticized for not investing enough in disaster mitigation infrastructure.
Elsewhere, its tsunami warning system has failed to avert deaths, in areas such as Palu in Central Sulawesi, where thousands died in a tsunami in 2018 unleashed by a quake of magnitude 7.5 after sirens did not go off in warning.
People in Aceh said they now receive regular training in responding to a big tremor or a tsunami. Still, Zainuddin, 54, who goes by one name, like many Indonesians, urged the government to beef up urban planning measures. 'Our streets are not wide enough, especially during rush hour, and it would be difficult to get through if a tsunami happened,' he said.
