It was nothing like December 2004. Sirens wailed, warnings blared and police moved people away from coastlines around the Indian Ocean as a powerful earthquake off northern Indonesia sparked fears of another devastating tsunami.
Damage was light and big waves never came in the wake of Wednesday’s quake, not like nearly eight years ago when walls of water roared across the Indian Ocean and ploughed into coastal communities in 13 countries without warning.
“The reports were of people panicking, but there was little damage. We need to check for sure directly though,” Eko Budiman, the deputy head of emergency mitigation, said at Medan airport in northern Sumatra, struggling to reach Simeulu island near the epicenter.
The alerts and evacuations mean a regional system passed a major test since it was set up after the massive quake and tsunami of 2004 that killed 230,000 people around the Indian Ocean, including 170,000 in northern Indonesia alone.
However, luck may have helped avert disaster this time as much as the warning system, especially in Indonesia’s Aceh Province, where roads were jammed with residents trying to flee.
“The simple message is that in any critical condition like this, it’s impossible to get everyone out in time,” said Keith Loveard, chief risk analyst at Jakarta-based security firm Concord Consulting.
“The tsunami alert system worked to a degree ... While awareness has improved, reinforced by 2004, it still needs to get better through public education and government campaigns,” he said.
The 2004 disaster swept in with sudden ferocity. Thailand’s southwestern beaches and hotels were packed with tourists on their Christmas vacations and people were out for a stroll on Chennai’s Marina Beach in southern India when the waves hit.
Made up of seismographic stations and deep-ocean sensors, the Indian Ocean Tsunami Warning System was activated in June 2006 after being agreed 17 months earlier at a UN conference in Japan.
When a quake hits, data is sent to the Pacific Tsunami Warning Center in Hawaii and the Japan Meteorological Agency, which coordinate with national tsunami centers in the region.
It can take 15 to 20 minutes for quake data to be analyzed and a tsunami watch to be issued to governments and the public around the Indian Ocean.
Nations, also using their own data, warn citizens in a variety of ways — from radio, television and text messages to sirens and loudspeakers used by mosques.
Thailand set up a national disaster-warning center in Bangkok that coordinates with its six Andaman coast provinces. The system includes clearly marked evacuation routes, sirens and buoys out at sea that monitor tides.
On Wednesday, the center issued a tsunami alert for the six southwestern provinces and tourists, residents and hospital patients were evacuated to higher ground.
“The hotel was very good, the staff were very good,” said one man staying on Karon beach in Phuket. “They got us moving very quickly, so we feel very safe.”
However, in Sri Lanka, many people were reluctant to move.
“I am still waiting because otherwise looters will rob us,” said Subramanium Sivalogan, a retired banker.
Others evacuated, but saw little point after losing all they had when communities on the South Asian island were wiped out in the 2004 tsunami.
“We are wasting our time like this because they say there is another one coming,” said Dali Silva, who took refuge in a Buddhist temple. “We didn’t get anything after the last tsunami. Every time they say there is a tsunami we run like this.”
The magnitude 8.6 quake on Wednesday and its aftershocks rattled buildings and nerves around the Indian Ocean, but authorities breathed a sigh of relief that it was not worse.
Meanwhile, Indonesian officials yesterday said five people died and at least seven were injured in Wednesday’s quakes.
They said they believed at least two people died of heart attacks and three others died of shock.
“Based on data collected on victims and damage, five people died, one person is critically injured and six others had minor injuries,” National Mitigation Agency spokesman Sutopo Purwo Nugroho said.
All of the casualties were in Aceh Province.
Nugroho said the critically injured victim was a child who fell from a tree during the quake.

SEEKING CHANGE: A hospital worker said she did not vote in previous elections, but ‘now I can see that maybe my vote can change the system and the country’ Voting closed yesterday across the Solomon Islands in the south Pacific nation’s first general election since the government switched diplomatic allegiance from Taiwan to Beijing and struck a secret security pact that has raised fears of the Chinese navy gaining a foothold in the region. The Solomon Islands’ closer relationship with China and a troubled domestic economy weighed on voters’ minds as they cast their ballots. As many as 420,000 registered voters had their say across 50 national seats. For the first time, the national vote also coincided with elections for eight of the 10 local governments. Esther Maeluma cast her vote in the
Nearly half of China’s major cities are suffering “moderate to severe” levels of subsidence, putting millions of people at risk of flooding, especially as sea levels rise, according to a study of nationwide satellite data released yesterday. The authors of the paper, published by the journal Science, found that 45 percent of China’s urban land was sinking faster than 3mm per year, with 16 percent at more than 10mm per year, driven not only by declining water tables, but also the sheer weight of the built environment. With China’s urban population already in excess of 900 million people, “even a small portion
UNSETTLING IMAGES: The scene took place in front of TV crews covering the Trump trial, with a CNN anchor calling it an ‘emotional and unbelievably disturbing moment’ A man who doused himself in an accelerant and set himself on fire outside the courthouse where former US president Donald Trump is on trial has died, police said yesterday. The New York City Police Department (NYPD) said the man was declared dead by staff at an area hospital. The man was in Collect Pond Park at about 1:30pm on Friday when he took out pamphlets espousing conspiracy theories, tossed them around, then doused himself in an accelerant and set himself on fire, officials and witnesses said. A large number of police officers were nearby when it happened. Some officers and bystanders rushed
HYPOCRISY? The Chinese Ministry of Foreign Affairs yesterday asked whether Biden was talking about China or the US when he used the word ‘xenophobic’ US President Joe Biden on Wednesday called for a hike in steel tariffs on China, accusing Beijing of cheating as he spoke at a campaign event in Pennsylvania. Biden accused China of xenophobia, too, in a speech to union members in Pittsburgh. “They’re not competing, they’re cheating. They’re cheating and we’ve seen the damage here in America,” Biden said. Chinese steel companies “don’t need to worry about making a profit because the Chinese government is subsidizing them so heavily,” he said. Biden said he had called for the US Trade Representative to triple the tariff rates for Chinese steel and aluminum if Beijing was
