Earth physics is a branch of physics that deals with the study of the physical properties and processes that occur within the Earth's interior, crust, and atmosphere. It includes the study of phenomena such as plate tectonics, earthquakes, volcanic eruptions, geomagnetic fields, and the Earth's climate [1,2]. One of the primary methods used in earth physics is seismology; it is the study of earthquakes and the propagation of seismic waves through the earth's interior, and its structure and composition, including the location of seismic activity and the behavior of tectonic plates [3]. They also use seismic waves to investigate the properties of materials within the earth's interior, such as density and elasticity.

Another method used in earth physics is geophysics, which involves the study of the earth’s gravitational, magnetic, and electric fields. For example, gravity surveys can be used to map variations in the earth's density, while magnetic surveys can reveal the presence of magnetic minerals in rocks and soils. Remote sensing is another important method used in earth physics [4,5]. It involves the use of satellite and airborne sensors to observe and measure the Earth's surface and atmosphere. Remote sensing can provide data on a wide range of phenomena, including changes in land cover and land use, ocean currents, and atmospheric composition [6]. It is particularly useful in monitoring environmental changes over time and understanding the impacts of human activities on the Earth's systems.

Numerical modelling is also an important tool in earth physics. It involves the use of computer simulations to model and predict the behavior of natural systems. Numerical models can be used to simulate the behavior of the Earth's atmosphere, oceans, and land surface, as well as the interactions between these systems [7,8]. They can also be used to investigate the impacts of climate change and other environmental factors on the Earth's systems.

In addition to these methods, earth physics also incorporates a range of other techniques, including geochemistry, geology, and hydrology. Geochemistry involves the study of the chemical composition of rocks and minerals, while geology focuses on the earth's structure and history [9]. Hydrology is the study of the Earth's water cycle, including the movement of water through the atmosphere, rivers, and groundwater systems.

Earth physics is a complex and interdisciplinary field that uses a range of methods to investigate the physical properties and processes that occur within the Earth's interior, crust, and atmosphere [10]. These methods include seismology, geophysics, remote sensing, numerical modelling, and other techniques. Earth physics plays a important role in understanding the causes and effects of natural disasters such as earthquakes, volcanic eruptions, tsunamis, and hurricanes. By studying seismic waves and volcanic activity, seismologists and volcanologists can make predictions about when and where these events may occur [11]. This information is crucial for emergency response planning, evacuation procedures, and disaster relief efforts. It also provides insights into the Earth's climate system, including its dynamics, feedback mechanisms, and long-term trends. By using numerical models and remote sensing techniques predict track changes in the Earth's climate, such as rising sea levels, changes in precipitation patterns, and temperature fluctuations. This information is essential for developing strategies to mitigate the impacts of climate change and to plan for future adaptation.


Earth physics has a wide range of applications, from predicting and mitigating natural disasters to monitoring environmental changes and exploring other planets. By using a range of methods, such as seismology, geophysics, and remote sensing, can gain a deeper understanding of the Earth's systems and develop strategies to protect and preserve the planet for future generations.
