Bagi yang ingin mempelajari perihal gempa bumi dan realtime seismometer maka kunjungi link : https://www.iris.edu/app/station_monitor/#Today/PS-PSI/webicorder/PS-PSI|11624257 . Link tersebut utk stasiun monitor yang ada di Parapat Sumatera Utara, sedangkan untuk stasiun lainnya yg terhubung ke server "iris" maka cek disini : https://www.iris.edu/app/station_monitor/
Station Monitor provides access to continuous, real-time ground motion from hundreds of locations around the globe. This data, collected by seismometers, measure motion generated by earthquakes, volcanic eruptions, and other seismic sources. By viewing the recordings from multiple stations, you can explore how ground motion changes at various locations relative to the earthquake. Lots of other things can cause the ground to move besides earthquakes.
By regularly monitoring one or more stations maybe will learn how to detect these non-earthquake sources!
