Japan Faces Emergency Preparations Frenzy After Historic Megathrust Earthquake Advisory

On August 8th, a 7.1 magnitude earthquake struck off the coast of Miyazaki Prefecture, causing injuries to 14 people. Japan's Meteorological Agency issued its first-ever “Megathrust Earthquake Advisory” following the quake, indicating an increased possibility of a major earthquake in the Nankai Trough region. This advisory has led to widespread concerns and reactions among the Japanese populace.
Following the alert, Prime Minister Fumio Kishida canceled his planned overseas trip. Japanese media reports indicate that a potential Nankai Trough earthquake could heavily impact areas along the Pacific coast, including Tokyo, with possible fatalities exceeding 320,000 and the destruction of at least 2.38 million homes in a worst-case scenario.
In the wake of these warnings, a shopping frenzy has erupted nationwide. Japanese citizens have begun stockpiling emergency supplies and daily necessities. A Tokyo supermarket posted a notice apologizing for the stock shortages and potential rationing of certain items, especially bottled water. Online platforms are reportedly showing high demand for portable toilets, canned food, and bottled water. This rush extends to retail stores along the Pacific coast, where disaster-related items are also in high demand.
Despite the increased risks, experts are urging the public to remain calm and avoid excessive hoarding. Authorities across Japan suggest that while preparedness is crucial, there is no need for panic buying. The earthquake advisory has also led to disruptions in the tourism sector. Popular tourist destinations have experienced a wave of cancellations. In Shizuoka Prefecture’s Izu Peninsula, over 550 reservations were canceled. Similarly, in Ehime Prefecture’s Matsuyama City, at least 1,000 bookings in the renowned Dogo Onsen area are expected to be canceled by mid-month.
Major tourist attractions in Wakayama Prefecture, such as the Shirahama beach, have been closed, and fireworks displays have been canceled. Hotels report numerous safety inquiries and a significant number of cancellations, totaling 350 reservations.
Historically, Japan experiences around 1500 earthquakes annually due to its location on four major tectonic plates. The government estimates a 70% probability of a large-scale earthquake occurring in the next 30 years. Despite the heightened probability of a megathrust earthquake, the government continues to advise against excessive hoarding of supplies.
The events have drawn significant attention, with social media flooded with personal accounts and imagery of the earthquake’s impact. While the advisory aims to prepare and inform, the resulting public unease highlights the challenges of striking a balance between raising awareness and inciting fear.
