Historic Earthquakes of New Zealand is a quick look at large Earthquakes that have been
recorded in New Zealand.
Seismic Waves shows how earthquake waves
spread out from an earthquake.
NZ Interactive Earthquakes has a two level
tutorial teaching students how to locate the epicentre of and earthquake. Level 3, which
is still under development, will test their new skill with real data taken from the Quake
Trackers’ seismogram database.
Seismic Eruption maps where and when
earthquakes have occurred in the last 40 years. Students can be led to some insightful
conclusions regarding the structure of the Earth’s crust.
WinQuake is a great programme for students
doing projects to use. It enables students to locate earthquakes from the QT seismogram
database and draws a map with results.
Earlier GNS Earthquake Reports is the
catalogue of magnitude and position for felt earthquakes made by the Institute of
Geological and Nuclear sciences (GNS).
NEIC Earthquake Search searches an
international earthquake catalogue. This catalogue often varies from the GNS catalogue as
it uses different seismometers.
Historic Earthquakes of New Zealand, Earlier GNS
Earthquake Reports and NEIC Earthquake Search run online.
Seismic Waves, Seismic Eruption , NZ Interactive
Earthquakes & WinQuake have links on the QT - classroom projects page.
From these links you download the programmes to your computer or network and install them.
Where you install them will depend on what best suits your system. We suggest a place
where all teachers can readily access them is best since all science and geography
teachers will want to use them.
