Two massive quakes off Indonesia’s Sumatra island in April showed something scientists have long been trying to prove – that large earthquakes can trigger a swarm of more tremors around the globe.
The latest findings could eventually help efforts to predict some earthquakes.
Over the six days after the quakes hit on April 11, the number of tremors of magnitude greater than 5.5 jumped nearly five-fold globally.
“This is the first time that we’ve seen these remote aftershocks at this magnitude and to this extent,” said Kerry Sieh, director of the Earth Observatory of Singapore, author of a number of studies on earthquake hazards in the Sumatra region.
The first quake on April 11 was 8.7 magnitude, nearly as large as the one which triggered a massive tsunami and nuclear disaster in eastern Japan just over a year earlier.
The second one was also huge, at 8.2. Both occurred under the Indian Ocean several hundred kilometres west of Sumatra, in a zone where the Indo-Australian tectonic plate is slowly tearing itself apart.

Syphilis outbreak in Houston and Harris County, Texas, USA. From January to August this year, there were 318 cases. Houston’s last syphilis outbreak occurred in 2007.

It is easily cured with a single shot of penicillin.
Ebola virus outbreak in DR Congo continues. A total of 79 cases had been recorded, including 19 confirmed positive after laboratory analysis, 32 probable cases and 28 suspected cases, while 33 deaths were registered by September 25. The disease is transmitted by direct contact with blood, faeces and sweat, by sexual contact and by unprotected handling of contaminated corpses. There is no known cure. Currently, 167 people who have been in contact with the 79 reported cases are under surveillance.

In the Western Pacific:
– Super Typhoon Jelawat is located approximately 430 nm south-southwest of Kadena Air Base, Okinawa, Japan. Expected to make landfall in Honshu, Japan. All models now track across Japan and into the Sea of Japan, but historically storms are not able to cross Japan’s mountainous geography.
– Tropical storm Ewiniar – was located approximately 345 nm south-southeast of Yokosuka, Japan. No threat to land.
A tornado has been reported Tuesday evening near the town of Okawville, just outside Saint Louis, Illinois, USA.
