To read the full story as it happened, we advise our readers to start at the lower part of the page (earthquake data).
Keep this page open or return regularly as we will be back with more details when they become available
Update 10:42 UTC
- Most aftershocks have an epicenter on a safe distance out of the Sumatra coast
- At this moment we can only tell that a real destructive tsunami has not yet occurred as far as we know. Additionally the epicenter is too far out of the coast to be shaking damaging. Light damage is still possible of course as the highest expected shaking is still a strong MMI VI shaking.
- People in the most dangerous area are well prepared these days and were also immediately alarmed to seek higher ground
- Many (powerful) aftershocks have occurred since the mainshock
- India’s tsunami warning center said waves measuring up to 6 meters were expected along parts of its eastern coast
- Very good news comes from Indonesia : Indonesia’s disaster mitigation agency says no detection of low tide that would indicate tsunami in Aceh (Reuters twitter)
- seismologists are reporting the the earthquake was from another type than the 2004 one. The thrust force was far less this time than in 2004. Thrust force is mainly generating tsunamis like what was the case in Japan
- As far as we know now – the closest shores (Northern Sumatra) has not yet experienced any important level change
- British Prime Minister Mr Cameron is visiting the country’s capital, Jakarta, which is 1,600 miles south-east of the province and on a different island, Java. He said he was ‘hugely concerned and ready to help’. There were reports of the water level dropping in the Thai resort of Phuket – a sign that the sea is drawing back in preparation to launch an enormous wave.

- Indonesia’s disaster mitigation agency is sending a rescue team to Aceh, after a massive 8.7 magnitude quake on Wednesday and tsunami warning knocked out the province’s electricity and send locals scrambling for higher ground.
- “The quake was felt very strongly. Electricity is down, there’s traffic jams to access higher ground. Sirens and Koran recitals from mosques are everywhere,” said Sutopo, spokesman for Indonesia’s disaster mitigation agency.
- USGS has decreased the magnitude to 8.6 and 22.9km depth
- Residents in Banda Aceh reported the ground shaking violently.
- “People are in a panic, and there are traffic jams everywhere in Banda Aceh,” local Metro TV reported.
- “There is potential for a tsunami to hit five provinces in the region — Aceh, North Sumatra, West Sumatra, Bengkulu and Lampung,” said Marzuki, an analyst at Indonesia’s Geophysics and Meteorology agency.
- “Earthquakes of this size have the potential to generate a widespread destructive tsunami that can affect coastlines across the entire Indian Ocean basin,” the US Pacific Tsunami Warning Center said.
- In India, the authorities issued a tsunami warning for the Andaman and Nicobar Islands, located in the Indian Ocean.
- The Indian National Centre for Ocean Information Services issued a red high-level warning for the islands, and also put out lower alerts for the coasts of Andhra Pradesh and Tamil Nadu states in the southeast of the country.
- There was chaos in the streets, with fierce shaking continuing for nearly four minutes.
“I was in the shower on the fifth floor of my hotel,” Timbang Pangaribuan told El Shinta radio from the city of Medan. “We all ran out. … We’re all standing outside now.”
He said one guest was injured when he jumped from the window of his room.
- The tremor was felt in Singapore, Thailand, Bangladesh, Malaysia and India. High-rise apartments and offices on Malaysia’s west coast shook for at least a minute.
- Thailand’s National Disaster Warning Center issued an evacuation order to residents in six provinces along the country’s west coast, including the popular tourist destinations of Phuket, Krabi and Phang-Nga.
- A tsunami watch was issued for countries across the Indian Ocean after a large earthquake hit waters off Indonesia on Wednesday, triggering widespread panic as residents along coastlines fled to high ground in cars and on the backs of motorcycles.
Some were crying. Others screamed “God as great” as they poured from their homes.
- we have terrible problems in being able to stay online as the server crashes regularly. Lack of finance for better solutions is witholding us from being more performant.
- People on Twitter said tremors were felt in Singapore, Thailand, Malaysia and India. High-rise apartments and offices on Malaysia’s west coast shook for at least a minute
The power has gone out in Banda Aceh and residents are moving to higher ground, said Sutopo Purwo Nugroho, a spokesman for the Indonesian National Disaster Management Agency.
The extent of the damage is still being assessed.
The quake was felt as far away as Bangkok and in southern India, residents said. Hundreds of office workers in Bangalore left their buildings, workers there said.
The quake was in roughly in the same area as a December 26, 2004, quake of 9.1 magnitude, which sent huge tsunami waves crashing into Sumatra
- A tsunami warning has been issued as Indonesia’s geophysical agency has registered an 8.9 magnitude earthquake in the Aceh region, off the western coast of northern Sumatra.
- USGS has calculated that 547,000 people will have experienced a MMI VII Very strong shaking. Earthquake-Report.com does NOT expect shaking victims BUT we expect serious danger for the Northern Sumatra coast (Banda Aceh area) and Simeulue island, both areas who were hardest hit in the earlier tsunamis
- USGS has decreased his initial magnitude from 8.9 to 8.7. Other agencies are reporting lower values (a big difference)
- NOAA is publishing good news for the USA west coast : …A STRONG EARTHQUAKE HAS OCCURRED BUT A TSUNAMI IS NOT EXPECTED ALONG THE CALIFORNIA/ OREGON/ WASHINGTON/BRITISH COLUMBIA OR ALASKA COASTS… NO WARNING… NO WATCH AND NO ADVISORY IS IN EFFECT FOR THESE AREAS.
BASED ON LOCATION OF THE EVENT BEING OUTSIDE THE PACIFIC BASIN THE EARTHQUAKE WAS NOT SUFFICIENT TO GENERATE A TSUNAMI DAMAGING
TO CALIFORNIA/ OREGON/ WASHINGTON/ BRITISH COLUMBIA OR ALASKA. RESIDENTS IN THE INDIAN OCEAN REGION SHOULD REFER TO THE PACIFIC
TSUNAMI WARNING CENTER MESSAGE.
- GDACS has issued a green earthquake report, but we predict that it will change soon into a RED tsunami report. Nor GDACS, not NOAA have issued tsunami notes yet, but we expect them to arrive soon.
- due to the huge number of people coming to read our report, the server hangs regularly even for us writing in it
- This earthquake has a lot of similar data as the giant destructive earthquake and tsunami from many years ago, killing thousands of people. A general tsunami alarm looks imminent for the entire area
- Extremely dangerous earthquake
Preliminary data are saying a +8 magnitude
The earthquake has been felt in Thailand and in Malaysia
A tsunami alarm will certainly in place in large parts of the area
