KOMPAS.com - Indonesia's Meteorology, Climatology and Geophysics Agency (BMKG) said that 59 earthquakes have been recorded in the country since the beginning of this year.
BMKG deputy for Geophysics Muhammad Sadly said that the earthquake almost occurs everyday, impacting the lives of the residents in the affected areas.
On January 14, the agency recorded eight earthquakes in only a day. Indonesia is one of the quake-prone countries as it is situated on the so-called Pacific Ring of Fire.
Monitoring a seismic gap area
"Monitoring the quake-prone areas can be based on a suspected seismic gap area, namely a potential earthquake zone but without earthquake activity in a long time," said Sadly on Saturday, January 23.

Some of the regions in the seismic gap areas with high potential for megathrust earthquakes include Mentawai Islands, West Sumatra, the Sunda Strait, South Bali, North Sulawesi, Maluku Sea, North Papua, and the Banda Sea.
Meanwhile, the seismic gap areas with active faults comprise the Lembang Fault in West Java, the Matano Fault in Central Sulawesi, the Sorong Fault in West Papua, and the Aceh Segemen Fault.
It is estimated that aftershocks will last approximately three to four weeks from the first earthquake. Sadly reminded the public to remain vigilant in facing possible powerful aftershocks.
