Current motion of Peninsular Malaysia using high precision GNSS / Nurhanani Abd Mutalib

Peninsular Malaysia is located relatively distant from Sumatra's seismic source zone, the closest earthquake location to Malaysia is around 350 kilometres away. Sumatran earthquakes have caused vibrations on multiple occasions. Peninsular Malaysia has been hit by major earthquakes from West Sum...
