Repeat of Friday’s Sabah quake could occur in next three decades
Historically, only three quakes with magnitudes larger than Friday’s quake have occurred in Sabah in the past 100 years. These quakes ranged from a magnitude of 6.1 to 6.3, while the recent temblor measured 6.0.
Given that these four quakes occurred in a century, another similar quake could happen in another 25 to 30 years, according to EOS Director Professor Kerry Sieh in an interview with TODAY. Smaller quakes, however, occur more often in the area. Assistant Professor Judith Hubbard noted that two quakes of magnitudes 5.1 and 5.3 occurred near Mount Kinabalu nearly 25 years ago.
The cause of the recent earthquake appears to be a sudden slip along a 10km fault close beneath the Earth’s crust, south of Mount Kinabalu. What’s next? Assistant Professor Emma Hill says that seismologists need to better understand the faults, collect sufficient data from past events and present conditions of crustal deformation to forecast the when the next quake would occur.
