- 1) Extensometer The extensometer is used to measure relative movement by comparing the extension of two points. The extensometers are generally installed across the main scarp, at transverse crack and transverse ridges near the toe or front portion of the slide and parallel to the suspected slide movement . By arranging a series of interconnecting extensometers from the main scarp to the toe of a complex landslide that has many moving slide blocks, the resulting data could aid in clearly delineating the individual slide blocks. Measurements should be accurate to within 0.2mm, and the magnitude of the movement and daily rainfall data should be included to establish the relationship between the measurable movement and the precipitation rate.
- 2)Tilt meter The ground tilt meter is useful for determining the deformation at the head and toe portions and sometimes along the flanks of the landslide, or to assess the possibility of future deformation. A level type tilt meter is most conventional. The tilt meter is capable of measuring the N-S and E-W components. The magnitude of tilting and tilt directions can be determined directly from the instrument panel. Furthermore, in order to determine the characteristics of the deformation, the results are shown chronologically along with the daily rainfall totals. The relationship between the magnitude of tilting and the cumulative effect of tilting, rainfall totals and groundwater levels are shown on Fig.17.

What instruments are used to monitor an el nino?
A variety of different instruments are used to measure and track El Nino. Altimeters, weather satellites, and scatterometers are all necessary instruments for measuring El Nino.
What are scientists that might be able to predict landslides?
Scientists usually use extensometer. But it is difficult to measure the whole landslide area.
Which scientific instrument is used to predict or measure earthquakes?
The strainmeter, by which its seismometer component detects the vibrations or shock waves that its seismograph records, is the scientific instrument that's used to predict and measure earthquakes.
What other instruments might an amateur meteorologist use to help predict the weather?
anemometer to measure the wind speed
Are landslides real?
Yes. Landslides are real events.

How can barometers be used to help predict the weather?
If it goes down the weather gets worse. If it goes up it get sunny and nice.

How can scientist predict where landslides could occur?
That is very difficult. They would need to be aware of the land that is unstable. Wet weather or an earthquake can be a contributory factor, so they would need to watch for that. Places where landslides have previously occurred need to be watched. Flat places are safe, so they would be looking at steep hills and valleys. If they look at all of these factors, they can have a chance of predicting one, but usually they happen quickly and there is little chance to predict them.
What three instruments are used to predict the weather?
The basic instruments used in meteorology measure the current state of the atmosphere, and include anemometers (wind gauges), thermometers, and barometers. These measure air flow, temperature, and air pressure.
What instruments are used in Tasmania?
As Tasmania is one of Australia's states, the instruments used there will be the same as the instruments used throughout Australia. there is a great variety of westernised instruments, as well as instruments from other cultures.
