The dormant volcano on the remote island erupted on January 5 and has since been emitting ash and steam.
Two officers from the Observatory are expected to be on site early next week to install the sensor.
“The sensor (seismometer) detects earthquakes (volcano-related),” the RVO explained to Loop PNG.
“The data recorded will help the guys in determining the status of the activity.”
Meanwhile, another RVO staff is expected in Wewak later today to carry out an aerial inspection of the volcanic island.
