- 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 are scientists that might be able to predict landslides?
Scientists usually use extensometer. But it is difficult to measure the whole landslide area.
What instruments are used to monitor an el nino?
Instruments commonly used to monitor an El Niño event include satellites for remote sensing of sea surface temperature anomalies, buoys to measure ocean temperatures and currents, and weather balloons to collect atmospheric data. These instruments help scientists track the development and intensity of El Niño events and make predictions about their impacts.
What kind of wheather often precedes landslides?
Heavy rainfall or snowmelt is often a precursor to landslides. This excessive water can saturate the soil, reducing its stability and leading to increased risk of landslides. Additionally, earthquakes can also trigger landslides by shaking loose already unstable slopes. Monitoring weather patterns and soil conditions can help predict and mitigate the risk of landslides.

What instruments do you use to predict the rain?
Meteorologists use various instruments to predict rain, including weather radar to detect precipitation, satellites to monitor cloud formation, and weather balloons to measure atmospheric conditions. Additionally, weather models that simulate the atmosphere's behavior are also used in conjunction with these instruments to forecast rain.
What are instruments used to predict eruptions?
Instruments used to predict eruptions include seismometers to detect earthquake activity, gas analyzers to monitor changes in gas emissions, thermal cameras to detect changes in temperature, and GPS sensors to measure ground deformation. These data are used by scientists to monitor volcanic activity and assess the likelihood of an eruption.
Who Scientists that predict landslides?
Geologists, civil engineers, and hydrologists are scientists who specialize in predicting landslides. They study the terrain, geological conditions, and weather patterns to assess the risk of landslides in a particular area. By analyzing these factors, they can provide early warning systems and mitigation strategies to help prevent damage from landslides.
What instrument are used to predict floods?
Instruments such as rain gauges, stream gauges, and weather radars are commonly used to predict floods. These instruments help monitor and measure rainfall, water levels in rivers and streams, and weather conditions that can cause flooding. Advanced technologies like hydrological models and satellite data are also used for flood prediction.
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.
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.
