Monitoring
PMGO monitors seismicity of the PNG region using a nation-wide
network that currently includes 13
seismograph stations ).
Earthquake records are telemetered to the strategically located
hub of the network, at Port Moresby, via the Telikom telephone
system.
Earthquake Mapping
Using appropriate computer software, staff at PMGO determine
locations and magnitudes of earthquakes in the PNG region.
The results of this analysis are routinely checked against the
results determined by other agencies, and re-determinations are
made where necessary to reduce location uncertainties.
For all felt and/or damaging earthquakes, location and magnitude
data and felt effects are promptly made known to PNG government
authorities and news media via Earthquake Information Bulletins.
The Observatory has established and maintains databases containing
information about earthquakes that occurred in the PNG region since
1900. From these data, areas of seismicity have been defined
(see map of historical earthquakes in the PNG region) and are progressively
being refined as more seismic data become available.
