TEMPO.CO, Jakarta - West Sumatra on Wednesday was hit by a series of earthquakes that are known to be centered on land. The magnitude 4.5 quake was first recorded at 10:46 Indonesia Western Time (WIB) 12 kilometers Northeast of West Pasaman and from a depth of 10 kilometers.
The strength of the quake was measured at III on the MMI scale, which resembles a truck passing by.
Tempo.co noted that this is the sixth earthquake based on land in West Sumatra since September 16, or the ninth in the region under the same time period.
The land earthquakes in West Sumatra were previously centered in Bukittinggi (four times) and Pariaman. In a statement given last Monday, the Acting Head of the BMKG Earthquake and Tsunami Center, Daryono, said that the Bukittinggi earthquake was triggered by an increase in the activity of the Sumatran Fault in the Sianok segment.
It is also observed that its activity is increasing in the Tripa segment. This is similar to what triggered the M4.5 and 5.1 earthquakes in Takengon, Central Aceh, on Monday and Friday last week.
