Understanding Earthquake Proneness: Myanmar’s Recent Disaster
On a fateful Friday, a devastating 7.7-magnitude earthquake struck Myanmar, resulting in widespread destruction and a catastrophe that is believed to have claimed thousands of lives. Myanmar’s geographical positioning plays a critical role in this seismic vulnerability. Situated at the intersection of two tectonic plates, the country is no stranger to seismic activity, particularly along the Sagaing fault, which runs perilously close to major cities such as Yangon and Mandalay.
The Sagaing Fault and Its Implications
The Sagaing fault is a significant geological feature that poses a severe threat to the nation. Given its proximity to densely populated urban areas, any seismic activity along this fault can have catastrophic consequences. The city of Mandalay, home to over 1.7 million residents, now faces the repercussions of an earthquake that struck near its epicenter. The aftermath is particularly grim for residents in Sagaing, the provincial capital, where the devastation is felt most acutely.
Tectonic Plates: A Risk Factor
The destructive earthquake in Myanmar was primarily triggered by lateral movement between tectonic plates rubbing side by side. This type of tectonic interaction often results in large, shallow earthquakes that can affect vast areas, leading to extensive damage. While some of the world’s most earthquake-prone countries are located near convergent plate boundaries, Myanmar’s position along a transform plate boundary makes it vulnerable to sudden seismic events. This geological configuration places the country within the top 30 nations that have experienced the most significant earthquakes in the past 35 years.
Building Infrastructure: A Critical Challenge
The severity and destruction caused by the recent quake were further exacerbated by Myanmar’s poor adherence to building codes. Since the military junta took control in 2021, the country has been embroiled in civil strife, resulting in a lack of oversight and enforcement of safety regulations. This situation has rendered many of the newly constructed buildings susceptible to collapse during seismic events.
Moreover, Myanmar’s rapid urbanization has seen a surge in the erection of modern buildings, most of which were poorly designed and built without following safety norms. Therefore, the risk to residents and infrastructure is magnified compared to previous decades, making the population increasingly vulnerable to such natural disasters.
Asia’s Earthquake Hotspots
While Myanmar is currently in the spotlight, it is not alone in facing the threat of earthquakes. According to data from the National Oceanic and Atmospheric Administration (NOAA), China and Indonesia are also among the countries with the highest number of earthquakes recorded since 1990, with 187 and 173 major quakes, respectively. Other Asian nations that frequently experience seismic activities include Japan, India, and the Philippines.
The European Context
In Europe, Greece and Italy are significant areas of concern regarding earthquake activity. Between them, they have reported 32 and 24 tremors since 1990, underscoring that seismic risks are not confined to the more well-known earthquake hotspots. These regions must continue to prioritize earthquake preparedness and infrastructure resilience.
The Turkish and Syrian Catastrophe
The seismic disaster in February 2023, which resulted in the deaths of nearly 60,000 people in Turkey and Syria, further underscores the dire repercussions of earthquakes. Turkey, which has experienced a staggering 65 major earthquakes since 1990, illustrates the ongoing threat posed by earthquakes to human life. Notably, six of these quakes had magnitudes of 7 or higher, compounding the challenge of disaster preparedness in the region.
Middle Eastern Earthquake Proneness
Iran is another country affected by significant earthquake activity, ranking among the countries with considerable seismic risks over the last several decades. Afghanistan also ranks as the 10th most affected nation, with 39 major earthquakes recorded since 1990.
Latin America’s Earthquake Risks
Turning to Latin America, Peru emerges as the country with the highest vulnerability to earthquakes in the region. The complex interplay of tectonic activity along the Pacific Ring of Fire, which encompasses various countries in this part of the world, contributes to the high incidence of seismic events in Peru and its neighbors.
Through this detailed exploration of Myanmar’s recent earthquake and the broader context of global seismic activity, it becomes evident that the risks posed by earthquakes are complex and multifaceted.
