Unveiling Post-Earthquake Anxiety Disorders:


The aftermath of an earthquake is a period characterized by not only physical devastation but also a profound impact on mental health. In recent years, researchers and mental health professionals have identified a surge in anxiety disorders following seismic events. This review aims to delve into the nuances of these new anxiety disorders that emerge post-earthquake, shedding light on their manifestations, underlying mechanisms, and potential interventions.

1- Types of Anxiety Disorders

a. Earthquake-induced PTSD (Post-Traumatic Stress Disorder)

Following a seismic event, - individuals may experience recurring and intrusive memories, flashbacks, and nightmares related to the earthquake. Hyperarousal, hypervigilance, and avoidance behaviors are common, contributing to the diagnosis of earthquake-induced PTSD.

b. Earthquake-related Phobias

Specific fears related to earthquakes, such as fear of aftershocks, enclosed spaces, or heights, can develop into phobic disorders. These phobias may significantly impact daily functioning and lead to avoidance behaviors, exacerbating anxiety.

c. Generalized Anxiety Disorder (GAD)

The uncertainty and unpredictability associated with earthquakes can contribute to the development of generalized anxiety. Individuals may worry excessively about future seismic events, their safety, and the safety of their loved ones, leading to chronic anxiety and tension.

d. Social Anxiety Disorder

Post-earthquake, individuals may develop social anxiety due to a heightened fear of judgment or criticism. Social situations may trigger anxiety, as survivors grapple with the perceived scrutiny of others or the fear of discussing their earthquake-related experiences.

2- Risk Factors

a. Proximity to the Epicenter

Those residing closer to the epicenter of the earthquake are at a higher risk of developing anxiety disorders. The intensity of the experience and the immediate impact on one's surroundings contribute to the psychological distress.

b. Loss of Loved Ones or Property

The loss of family members, friends, or property during the earthquake can intensify the emotional toll, increasing the likelihood of developing anxiety disorders.

c. Previous Mental Health History

Individuals with a pre-existing history of anxiety or mood disorders may be more vulnerable to developing post-earthquake anxiety disorders. The seismic event can act as a trigger, exacerbating existing mental health challenges.

3- Neurobiological Mechanisms

a. Hyperactivation of the Amygdala

The amygdala, a key brain region involved in processing emotions, is hyperactivated in response to the traumatic experience of an earthquake. This heightened emotional response contributes to the development and persistence of anxiety disorders.

b. Hippocampal Changes

Structural changes in the hippocampus, a region critical for memory consolidation, have been observed in individuals with post-earthquake anxiety disorders. These changes may influence the formation of traumatic memories and contribute to the development of PTSD.

4- Interventions and Treatment Approaches

a. Cognitive-Behavioral Therapy (CBT)

CBT has demonstrated efficacy in treating various post-earthquake anxiety disorders by addressing maladaptive thought patterns, promoting coping strategies, and facilitating exposure therapy to reduce avoidance behaviors.

b. Medication

In some cases, pharmacological interventions such as selective serotonin reuptake inhibitors (SSRIs) or benzodiazepines may be prescribed to alleviate symptoms. However, these should be used judiciously, considering individual differences and potential side effects.

c. Community Support and Education

Establishing community support networks and providing education on coping mechanisms and resilience can play a crucial role in mitigating the impact of post-earthquake anxiety disorders. Psychosocial interventions that foster a sense of community can enhance emotional well-being.


As earthquakes continue to pose a threat to communities worldwide, understanding and addressing the mental health implications of seismic events are paramount. This review underscores the importance of early intervention, community support, and a multidisciplinary approach to alleviate the burden of anxiety disorders in the aftermath of earthquakes. Ongoing research is essential to refine our understanding of these disorders and inform effective strategies for prevention and treatment.
