News India Live, Digital Desk: Japan, a country sensitive to natural disasters, has once again been shaken by the havoc of nature. The powerful 7.4 magnitude earthquake that struck off the coast of northern Japan on Monday morning not only shook buildings but also raised alarm bells for the global economy. Japan Meteorological Department Aomori And Miyagi A tsunami warning has been issued for the provinces, where waves of 1 to 3 meters are expected.
1. Center and intensity of the earthquake
Intensity: 7.4 on the Richter scale (powerful category).
Time: Monday, April 20, 2026, around 8:16 AM (local time).
Effect: Strong tremors were felt in large parts of northern Japan, including Tokyo. Bullet trains (Shinkansen) were immediately stopped and safety checks of nuclear plants were started.
2. ‘Aftershock’ on markets and supply chains
This part of Japan is close to the manufacturing hubs of many of the world’s leading tech and auto companies. Economic experts have warned of disruption in the following areas:
Semiconductor and Silicon Chips: Several plants in northern Japan control a large share (about 20–25%) of the global silicon wafer supply. If these plants remain closed for a long time, the prices of smartphones and laptops may rise.
Automobile Sector: Suppliers of giants like Toyota and Nissan are located in this area. The ‘just-in-time’ delivery model has been affected due to power cuts and logistics disruptions due to the earthquake.
Stock market trend: The Nikkei and other Asian markets have seen uncertainty as investors fear that the huge cost of reconstruction could hit the liquidity of Japanese banks.
3. Danger and relief work of ‘Tsunami’
Coastal areas were evacuated: The administration has instructed people living in coastal areas to immediately move to higher places.
Electricity and water crisis: According to initial reports, thousands of homes have lost power and incidents of fire have also been reported at some places.
4. Impact on the global market (The Domino Effect)
Japanese banks hold billions of dollars worth of securities abroad. If the cash crunch in Japan increases due to the disaster and Japanese banks start selling their foreign assets, it could also lead to a decline in the stock markets of the US and Europe.
