1.1 Introduction
Earthquake risk preparedness and mitigation refer to the systematic processes and measures undertaken to anticipate, prevent, reduce, and respond effectively to the impacts of seismic events on human life, infrastructure, and the environment. Preparedness involves planning, capacity building, and the establishment of early warning systems, while mitigation focuses on long-term strategies such as enforcement of building codes, land-use planning, and public awareness aimed at minimizing potential damage (UNISDR, 2015).
Although earthquakes are often associated with tectonically active regions, recent studies have shown that intraplate seismic activities also occur in regions previously considered stable, including parts of Nigeria (Akinyemi, 2014). As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Historically, earthquake risk preparedness and mitigation in Nigeria is closely linked to the broader development of geological studies and disaster management frameworks within the country. Although Nigeria is not located along major tectonic plate boundaries, historical records indicate that the country has experienced minor earth tremors, which have drawn attention to the need for systematic monitoring and preparedness. Early geological investigations in Nigeria primarily focused on mineral exploration and resource mapping, with limited emphasis on seismic risk assessment.
According to Akinyemi (2014), natural hazards, including earthquakes, have the potential to disrupt socio-economic development when adequate preparedness measures are not in place. Nigeria is traditionally categorized as a low seismicity region; however, recorded earth tremors in parts of the country have challenged this long-standing assumption. Adedoyin et al. (2017) reported that occurrences of minor tremors in locations such as Abuja, Ibadan, and Kaduna have raised awareness about the possibility of underlying geological instabilities.
The Nigerian Geological Survey Agency (NGSA), established to provide geoscientific data and advisory services, plays a central role in monitoring and managing geological hazards. Nwankwo (2020) asserted that the agency is responsible for conducting geophysical surveys, maintaining seismic monitoring networks, and providing essential data for policy formulation. Despite these responsibilities, there are concerns regarding the agency's operational efficiency, particularly in relation to technological capacity, funding, and data dissemination.
Urbanization in Nigeria, especially in Abuja, has further intensified the relevance of earthquake risk preparedness. Eze and Okeke (2018) stated that rapid infrastructural development, often carried out without strict adherence to building regulations, increases the vulnerability of structures to seismic shocks. The concentration of critical infrastructure and population in urban centers means that even low-magnitude earthquakes is likely to result in significant damage and disruption. This situation underscores the importance of integrating seismic considerations into urban planning and construction practices. In addition to infrastructural vulnerabilities, policy and institutional gaps also contribute to the challenges of earthquake risk management in Nigeria. Olorunfemi and Raheem (2019) affirmed that disaster management efforts in the country have historically focused on more frequent hazards such as flooding and erosion, thereby leaving seismic risks relatively neglected.
Public awareness and community preparedness represent another critical dimension of the problem. Akinyemi (2014) contended that effective disaster risk management requires active participation from both government institutions and local communities. In Nigeria, however, awareness of earthquake risks remains low, and many citizens lack basic knowledge of safety measures to adopt during seismic events. Furthermore, technological and data-related challenges hinder effective earthquake risk preparedness in Nigeria. Adedoyin et al. (2017) reported that the availability of modern seismic monitoring equipment is limited, and existing facilities are often inadequate for comprehensive nationwide coverage. Reliable data is essential for risk assessment, early warning systems, and policy development, yet its scarcity poses a significant obstacle to effective mitigation efforts.
Nwankwo (2020) asserted that effective disaster response requires collaboration among various agencies, including emergency management bodies, urban planning authorities, and scientific institutions. In Nigeria, however, coordination among these entities is often fragmented, leading to inefficiencies in preparedness and response mechanisms. The absence of clearly defined roles and communication channels further exacerbates the challenges associated with managing earthquake risks (Nwankwo, 2020).
This study is set against the backdrop of increasing concerns about Nigeria's vulnerability to seismic hazards and the need to strengthen institutional capacity, improve public awareness, and enhance policy frameworks for effective earthquake risk preparedness and mitigation.
1.3 Statement of Problems
Investigation revealed that awareness of earthquake risks among policymakers and the general public remains relatively low. While disaster management structures exist under broader emergency frameworks, they often prioritize more frequent hazards such as flooding and erosion, leaving seismic risks under-addressed (Olorunfemi & Raheem, 2019). On the other hand, the increasing urbanization and infrastructural development in cities like Abuja heighten the potential impact of even minor seismic events, thereby making preparedness a pressing concern.
Furthermore, there is a noticeable lack of enforcement of building codes and land-use regulations that incorporate seismic safety considerations. Many structures in Nigeria are constructed without adherence to standardized engineering practices capable of withstanding seismic shocks (Eze & Okeke, 2018). The implication is that even low-magnitude earthquakes is likely to result in significant structural damage and loss of lives due to poor construction practices. It is against this backdrop that this study seeks to examine the level of earthquake risk preparedness and mitigation in Nigeria, with particular focus on the Nigerian Geological Survey Agency, Abuja.
1.4 Aim and Objectives of Study
The aim of this study is to examine earthquake risk preparedness and mitigation strategies in Nigeria using the Nigerian Geological Survey Agency, Abuja as a case study. In achieving this aim, the following specific objectives were laid out as follows:
