Advanced Seismic Network Management in Papua New Guinea
The seismic network in Papua New Guinea, managed by the Port Moresby Geophysical Observatory, plays a crucial role in recording earthquakes, determining their characteristics, and providing early warnings. The network comprises national and local stations equipped with seismometers, accelerometers, and data loggers. Data acquisition is facilitated through software systems like SeisComP3, enabling regional data access and analysis. The network aims to inform stakeholders, enhance disaster preparedness, and collaborate for mitigating natural disasters.

Seismic Network in PNG Seismic Network in PNG Port Moresby Geophysical Observatory (PMGO) Geohazards Department of Mineral Policy & Port Moresby Geophysical Observatory (PMGO) Geohazards Management Division Department of Mineral Policy & Geohazards Management Division Geohazards Management (DMPGM) Management (DMPGM) Managing data for seismic networks, Hanoi, 2015
Purpose of the network To be able to record earthquakes as and when they happen Purpose of the network To be able to determine their location, size and damage potential To be able to inform relevant stakeholder partners, line agencies & the public of their significance To be able to provide partial tsunami early warning where necessary to disaster authorities To be able to share data for the common goal towards saving lives and property from natural disasters Managing data for seismic networks, Hanoi, 2015

Network setup Network setup Seismometers 1Hz 3c-short period (Lenartz LE-3DLite) Accelerometers triaxial, low noise, MEM, (Reftek 131A-02/3) Digitizer Reftek data loggers (Reftek 130-01/6) Accessories comms., power, gps, etc., Managing data for seismic networks, Hanoi, 2015
Network setup Network setup Indoor unit Indoor unit Outdoor unit Outdoor unit Seismometer (Lennartz LE-3DLite) Modem Router Accelerometer (Reftek 131 02/3) Data logger (Reftek 130 1/6) Managing data for seismic networks, Hanoi, 2015
Data acquisition system Data acquisition system Data acquired from local stations are done using Reftek s supplied software Regional data are accessed via internet through seedlink protocol plug-ins, installed with SeisComP3 software at the central server The network utilises SeisComP3 as the primary software for data acquisition, analysis and archival Managing data for seismic networks, Hanoi, 2015
Seismic data processing Seismic data processing Data processing is done using the SeisComP3 software for weak motion events For strong motion events - analysis are done using the Compass software from Reftek Inc. Data storage and archival Merged and archived into one server also stored on tapes Data stored in both seed and reftek format Managing data for seismic networks, Hanoi, 2015
Outcomes Outcomes The ultimate goal is to provide timely early warning seismic information to disaster authorities public safety Updating of earthquake database for the PNG region through earthquake cataloging Planning for the effects of earthquakes and tsunamis promotes safer communities Managing data for seismic networks, Hanoi, 2015
Future plans Future plans To expand on the existing setup as required Option to upgrade current setup to bb status Option to improve telemetry issues for reliability and a robust data acquisition system Provision of data sharing with regional data centers and other monitoring organizations for a collective benefit Managing data for seismic networks, Hanoi, 2015
