He noted the earthquakes that hit North Sumatra and Aceh originated from the Sumatra Fault segments, and some were scattered in several subduction areas.
"Stay alert and do not panic. Keep responding quickly to BMKG's information and maintain your distance when a significant earthquake occurs during the pandemic," he emphasized.
