Aftershocks of the 6.8 quake: Molucca Sea (Indonesia), 9 Jul 1986 23:10
More info
Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 631 km
2 (=244 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 44 km (27 mi).
Aftershocks typically occur during the weeks and months following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the
map below to verify).

17 days volcano trekking: This is one of our most exciting volcano tours! Halmahera, North Sulawesi and the Sangihe Islands are not only very scenic and interesting as well as nearly unspoiled by tourism, but also home to some of the country's most active (and often erupting) volcanoes, inclduing Dukono, Ibu, Lokon, Soputan and Karangetang.
Do you know which is the biggest volcano in the world?
Green Volcanoes: The Azores, a cluster of volcanic islands in the Atlantic Ocean, are famous for their very pleasant climate, breathtaking green and unspoiled landscapes and nature. They also have deep history and you'll find warm hospitality. Our new tour, guided by a photographer and volcanologist, will lead to five islands: Sao Miguel, Faial, Terceira, Pico and Flores - each with its distinct character to discover.
Active volcanoes in China: Did you know that there are at least 15 active volcanoes in China? The last eruption was from the Kunlun volcano in 1951.
