For our first week we brainstormed our existing knowledge on disasters with each other. We categorised this information into three groups:
How they occur?
Information on historic disaster
How to keep safe when they occur?

What's the Plan Stan?
Our inquiry focus for this term Natural Disasters and how to prepare for them.

..Love the big poster format to get your ideas down room 15, great!
I have copyed alot of information on the napier earthquake and have some photos too. Here is some information on it from celine:
1.
*Location: Hawke’s Bay
*Date (NZ Summer Time): Tuesday, *February 3 1931 at 10:47 am
*Epicentre: 39.3°S, 177.0°E
*Focal Depth: 20 km
*Maximum Intensity: MM 10
*Magnitude: 7.8
*Casualties: 256 killed, thousands injured
2.
The exact number of deaths varies according to different sources; the New Zealand Listener article cited below gives 258 deaths, but the Bateman New Zealand Encyclopedia gives 256. The difference is due to two people "missing" and presumed dead. Some articles add these two to the death toll, while others do not.
Awesome researching Celine!! This information will be really usual for you and others later on the term. What a star!!
Epicentre: The point on the earth's surface vertically above the hypocenter.
Mr D I have some glossary based on earthquakes.Please read it and the infomation on the aftershocks.
Thank You!
Aftershocks:There were 525 aftershocks recorded in the following two weeks. The main shock could be felt in much of the lower half of the North Island.
Glossary:
*Fault: A fracture, along which the blocks of crust on either side have moved relative to one another in a direction parallel to the fracture.
*Fissure: A long narrow crack in the ground caused by earthquakes.
*Focal depth: The depth of an earthquake's hypocenter.
*Focus: See hypocenter.
*Hypocentre: The point on the fault plane where the rupture starts.
*Intensity: A measure of how strongly an earthquake manifests at the surface, based on its observable effects on people, buildings and the environment. Intensity is usually ranked using the 12 point
*Liquefaction: A process in which water-saturated sediment temporarily loses its strength and acts as a fluid.
*Magnitude: A measure of the energy released by an earthquake at its source. Magnitude is commonly determined from the shaking recorded on a seismograph. Each unit of magnitude on the scale represents a substantial increase in energy, for example a magnitude 5 releases 30 times more energy than a magnitude 4.
*MMI: An abbreviation for Modified Mercalli Intensity (see Intensity above).
*Sandblows: When waves from a large earthquake pass though wet, loose sand, patches of sand erupt from below the surface onto the ground and form sandblow deposits.
*Slumping: When loosely consolidated materials or rock layers move a short distance down a slope.
*Subduction zone: The area or zone where two tectonic plates come together, one riding over the other.
*Swarm: An earthquake swarm is a sequence of nearby earthquakes striking in a short period of time.
*Tectonic uplift: Elevation of the ground caused by plate movement.
