  2. AUCKLAND ISLANDS NEW ZEALAND • Auckland Islands in New Zealand is the region that had earthquake on Sunday, September 30, 2007 at 09:47:49 UTC(GMT). • This earthquake ended on Sunday, September 30, 2007 at 08:47:49 PM at epicenter. • Its magnitude is 6.6.

  3. Distances • 235 km (145 miles) WNW of Auckland Island, New Zealand where the closest area the earthquake happened.505 km (315 miles) SW of Invercargill, New Zealand1275 km (790 miles) SW of WELLINGTON, New Zealand1950 km (1210 miles) SSE of CANBERRA, A.C.T., Australia

  4. More depth INFO • Location • 49.409°S, 163.265°E • Depth • 10 km (6.2 miles) set by location program • Parameters • Nst=228, Nph=228, Dmin=>999 km, Rmss=1.22 sec, Gp= 32°,M-type=moment magnitude (Mw), Version=S • Source • USGS NEIC (WDCS-D) • Event ID • us2007hxax

  8. P – waves P wave speed = 5 Km / sec • P-wavesare one of the types of elastic waves. It is also called seismic waves, that can travel through elastic solids and liquids, including the Earth. The waves can be produced by earthquakes and recorded by seismometers. And the P-wave is the fastest wave among the elastic waves, compared to the S-waves.

  9. S - waves • S – wave has speed, 60 % of P – wave’s speed. • The S-wave moves as a shear or transverse wave, so motion is perpendicular to the direction of wave propagation: S-shaped, like waves in a rope, as opposed to waves moving through a slinky, the P-wave.

  10. Conclusion • The area where had earthquake that I have searched is AUCKLAND ISLANDS in New Zealand.In this area, there wasn’t quite strong earthquake, but there was an earthquake for about 10 hours. • This earthquake is from S – waves, which is slower than P – waves, and goes perpendicularly. • On Sep 30 11:00 AM , that time was the time that earthquake was occur. Then later, it began to be calm down.
