Magnitude 5.7 Earthquake Hits Central Japan: Over 20 Injured, No Tsunami Warning Issued

A strong earthquake rattled central Japan in the early hours of Sunday, November 8, leaving more than 20 people injured, damaging shops and disrupting railway services. The magnitude 5.7 earthquake struck western Shizuoka Prefecture, sending residents rushing out of buildings as tremors shook several neighbouring regions.

Although no tsunami warning was issued, the earthquake prompted fresh concerns about seismic activity in the region. Japanese authorities have urged residents to remain alert for possible aftershocks over the coming days.

According to reports, at least 22 people were injured, with some suffering falls while attempting to evacuate buildings during the shaking. The incident also caused visible damage to commercial properties, with shattered shop windows and merchandise scattered across streets and floors.

Japan Earthquake: What Happened in Central Japan?

According to the Japan Meteorological Agency (JMA), the earthquake struck at approximately 1:04 am local time on Sunday.

The epicentre was located in the western part of Shizuoka Prefecture, at a depth of around 40 kilometres beneath the Earth's surface.

The JMA recorded the earthquake at magnitude 5.7, while the United States Geological Survey (USGS) reported a magnitude of 5.5.

The strongest shaking was recorded in Chita city in Aichi Prefecture, where the earthquake registered an upper 5 on Japan's seven-level seismic intensity scale.

Tremors were also felt across several neighbouring prefectures, including Nagano and Gifu. The shaking extended to areas around Hamamatsu, Kyoto and Nara, highlighting the geographical reach of the earthquake.

Tokyo, however, did not experience the tremors.

Despite the intensity of the shaking, authorities confirmed that there was no tsunami threat, offering some relief to residents in the affected regions.

More Than 20 Injured as Earthquake Damages Shops and Buildings

The earthquake left a trail of disruption across parts of central Japan, with at least 22 people reported injured in initial accounts.

Some residents were hurt while trying to escape buildings during the tremors, with reports indicating that people fell on staircases while rushing to safety.

Japanese television footage showed shattered storefront windows and broken glass scattered across streets.

A particularly striking scene emerged from a bookstore in the affected region, where numerous books had fallen from shelves and piled up on the floor following the earthquake.

In Toyota city, merchandise was also reported to have fallen from bookstore shelves, while a car dealership in Toyohashi city suffered damage to its windows.

Although authorities did not report any immediate fatalities, the incident once again highlighted how even a moderate-to-strong earthquake can disrupt daily life and cause injuries in densely populated areas.

Japan Meteorological Agency Warns of Possible Aftershocks

Following the earthquake, the Japan Meteorological Agency urged residents to remain cautious and prepare for the possibility of further strong tremors.

Officials warned that the risk of additional earthquakes could remain elevated over the coming week, particularly during the next two to three days.

Residents were also advised to watch out for secondary hazards, including landslides, falling rocks and potential damage caused by rainfall.

The warning is especially important for people living in areas where slopes and unstable terrain could become dangerous following seismic activity.

While aftershocks are a common occurrence following earthquakes, authorities have encouraged residents not to become complacent and to follow official safety instructions.

People have also been advised to keep essential supplies such as bottled water, food, batteries and emergency footwear readily available.

Shinkansen Bullet Train Services Disrupted

The earthquake also affected transportation across parts of central Japan.

Several railway services experienced temporary disruptions as operators carried out safety checks to assess possible damage to tracks and railway infrastructure.

Shinkansen bullet trains operating in the affected areas were running at reduced speeds as a precautionary measure.

The Tokaido Shinkansen line, which connects major cities including Tokyo and Osaka, also experienced delays between Shizuoka and Gifu-Hashima stations while inspections were conducted.

The precautionary measures were necessary to ensure passenger safety, as earthquakes can cause damage to railway infrastructure that may not be immediately visible.

For commuters and travellers, the disruptions added another layer of inconvenience to an already unsettling morning.

Did the Earthquake Affect the Nankai Trough?

The latest earthquake has also brought renewed attention to Japan's Nankai Trough, an offshore region where scientists have long warned of the possibility of a major earthquake.

The Nankai Trough is located along a major tectonic boundary and is considered one of Japan's significant seismic risk zones.

However, the Japan Meteorological Agency stated that no apparent changes had been detected in the Nankai Trough following Sunday's earthquake.

Officials have not established a connection between the latest tremor and the possibility of a major Nankai Trough earthquake.

While the region remains under scientific observation, authorities have urged the public to rely on official updates rather than speculation.

Why Is Japan So Vulnerable to Earthquakes?

Japan is among the world's most earthquake-prone countries because of its geographical location along the Pacific Ring of Fire.

The country sits near the boundaries of several tectonic plates, where continuous geological movement creates frequent seismic activity.

As a result, earthquakes are a regular part of life for millions of people across Japan.

The country has invested heavily in earthquake-resistant buildings, early-warning systems, emergency response infrastructure and public preparedness programmes.

However, the devastating 2011 earthquake and tsunami, which claimed thousands of lives and triggered the Fukushima nuclear disaster, remain a reminder of the destruction that powerful seismic events can cause.

Even with advanced safety measures, smaller and moderate earthquakes can still lead to injuries, property damage and transportation disruptions.

Authorities Continue to Monitor the Situation

The magnitude 5.7 earthquake in central Japan has once again placed attention on the country's seismic preparedness.

With more than 20 people injured, damage reported across affected areas and railway services disrupted, authorities are continuing to monitor developments.

Although no tsunami warning was issued and no immediate major threat was identified at the Nankai Trough, the possibility of aftershocks remains a concern.

For residents, the priority over the coming days will be staying informed, following evacuation guidance where necessary and taking basic precautions.

Japan's experience with earthquakes has taught its people the importance of preparedness. Sunday's tremor serves as another reminder that even when the immediate danger passes, caution remains essential.
