Recent Earthquakes in Japan: A Look at Seismic Activity
Table of Contents
Japan experienced a relatively quiet week in terms of felt earthquakes compared to the previous week,according to recent reports. While seismic activity was noted around the Kanto region and southern Kyushu, only three earthquakes with a seismic intensity of 3 or higher were recorded between December 16th and 22nd (as of 10:00 AM).
Important Quake Strikes Southern Ibaraki Prefecture
On Tuesday, December 17th, at approximately 10:11 PM, a magnitude 4.2 earthquake struck southern Ibaraki Prefecture. The quake, originating at a depth of 54 kilometers, registered a maximum seismic intensity of 4 in Utsunomiya City and Mibu Town, Tochigi Prefecture. A seismic intensity of 3 was also felt in several other cities across Tochigi and Ibaraki prefectures, as well as Higashimatsuyama City in Saitama Prefecture. “This is the first time in four months that an earthquake with a seismic intensity of 4 or higher has occurred in the Kanto region,since the earthquake in northern Ibaraki Prefecture on August 19th (maximum seismic intensity 5 lower),” a seismologist noted.
Analysis indicates the earthquake was a reverse fault type, with a pressure axis running northwest-southeast. The area, at a depth of around 50 kilometers, is known for its seismic activity, even within the relatively stable Kanto region. “The southern part of Ibaraki Prefecture…is an area known as an ‘earthquake nest’ where seismic activity is active even in the Kanto region,” experts explain.A magnitude 4.3 earthquake hit the same area earlier in December, and a more significant magnitude 5.3 quake (with a maximum seismic intensity of just under 5) occurred in March.
While this recent activity serves as a reminder of Japan’s susceptibility to earthquakes, the overall number of felt earthquakes this past week remained relatively low. The continued monitoring of seismic activity in the region remains crucial for preparedness and public safety.
Recent Earthquake Activity in Japan: A Deep Dive
Japan experienced a series of significant seismic events in late December 2024, prompting renewed concerns about the country’s vulnerability to earthquakes. These events highlight the complex geological factors at play and the ongoing need for preparedness.
Shallow Earthquake and Numerous Aftershocks
Following an initial quake, a flurry of aftershocks rattled the region.In the immediate aftermath, the area experienced a high frequency of tremors. Specifically, 33 noticeable quakes occurred in just over an hour on December 26th, followed by 59 more on the 27th. Further significant events included a magnitude 4.7 earthquake on December 28th and a magnitude 4.9 quake on December 30th, along with six additional quakes registering a magnitude of 3 or higher. While the frequency of aftershocks is decreasing, the shallow depth of the epicenter means the potential for further strong shaking remains.
The continued rainfall adds another layer of concern, potentially loosening the ground and increasing the risk of landslides.Authorities urge residents to avoid hazardous areas, such as steep slopes.
Deep Earthquake and Unusual Seismic Patterns
On December 17th, a magnitude 5.2 earthquake struck off the west coast of the Satsuma Peninsula in Kagoshima Prefecture. Unlike the shallow quakes, this one originated at a depth of 164 kilometers. The maximum seismic intensity reached level 3 in Minamisatsuma City, with weaker tremors felt across Miyazaki and Kagoshima prefectures. Interestingly, the intensity level 1 tremors were more widespread in Shikoku than in northern Kyushu, closer to the epicenter.
This unusual distribution of seismic intensity,known as an “abnormal seismic area,” is a common phenomenon with deep earthquakes. The strong shaking is transmitted along the subducting plate, often resulting in stronger shaking further away from the epicenter. In this case, the earthquake appears to have occurred where the Philippine Sea Plate subducts under the Eurasian Plate, with the shaking traveling along the philippine Sea Plate towards the Pacific Ocean.
While these events are geographically distant from the United States, they serve as a reminder of the powerful forces shaping our planet and the importance of global seismic monitoring and preparedness. understanding these events helps scientists refine earthquake prediction models and improve safety measures worldwide.
Powerful Earthquakes Rock the Globe: Vanuatu and the sea of Okhotsk
Two significant earthquakes rattled the globe this week, one near the island nation of Vanuatu and another in the remote Sea of Okhotsk. These powerful tremors highlight the dynamic nature of the Earth’s tectonic plates and underscore the importance of preparedness in earthquake-prone regions.
Vanuatu Earthquake: Magnitude 7.3 Tremor Strikes
On Tuesday morning (Japan time),a major earthquake struck east of Vanuatu,registering a magnitude of 7.3 according to the U.S.Geological Survey (USGS). The quake’s epicenter, located approximately 57 kilometers below the ocean’s surface, resulted in strong shaking felt across the island nation. ”The epicenter was close to the island, so it experienced strong shaking,” a USGS report stated, estimating the intensity at around VIII on the revised Mercalli intensity scale—equivalent to a 5+ on the Japan Meteorological agency’s scale. This intense shaking caused damage to buildings in Port Vila, Vanuatu’s capital.
While a tsunami was generated,the maximum wave height observed in Port Vila was only 0.25 meters, preventing significant tsunami-related damage. “Based on the depth of the epicenter and the mechanism, it appears that the earthquake was caused by a rupture within the Australian Plate,” the USGS analysis concluded.
Sea of Okhotsk Earthquake: Deep Tremor Felt Across Northern Japan
On Saturday, December 10th, a magnitude 6.8 earthquake struck the southern Sea of Okhotsk. This deep earthquake, occurring at an approximate depth of 490 kilometers, resulted in a unique seismic intensity distribution. While the epicenter was relatively close to Hokkaido, Japan, seismic intensity 3 was observed in several cities across Hokkaido and Tohoku, hundreds of miles away. This phenomenon, known as an “abnormal seismic area,” is common in deep earthquakes where strong shaking is transmitted along subducted plates.
“in deep earthquakes, strong shaking is transmitted along the subducted plate, and the shaking can become large in the distance near the plate boundary,” explains a seismological report. The report further notes that similar deep earthquakes have occurred in the Sea of Okhotsk in the past, with the 2012 magnitude 7.3 earthquake causing shaking that reached as far as the Kanto region.
These events serve as a reminder of the unpredictable nature of seismic activity and the importance of earthquake preparedness, not only in regions known for frequent tremors but also in areas that may experience less frequent, but still significant, seismic events.
New Jersey earthquake Shakes New York: Uncommon Tremor Rattles the Northeast
A significant earthquake, registering a magnitude of 4.8, struck New Jersey on Friday night (December 5th, 2024, Japan time), sending tremors across New York and causing a noticeable shake in the region. The quake, with an epicenter near New York City and a depth of approximately 5 kilometers, was a rare event for the typically seismically quiet northeastern United States.
The shaking intensity reached a level IV on the revised Mercalli intensity scale in central New York, which, while not directly comparable, is roughly equivalent to a seismic intensity of 1 to 2 on the Japanese scale. This means many people felt the shaking, though significant damage was thankfully avoided.
“This earthquake is thought to have caused shaking of IV magnitude on the revised Mercalli intensity scale,even in central New York,” stated a report from Weathernews. “Although it is not possible to make a precise comparison, the shaking corresponds to a seismic intensity level of 1 to 2 in Japan’s seismic intensity scale.”
A Rare Event in the Northeast
Earthquakes of this magnitude are uncommon in the northeastern U.S. according to seismic data, only 40 earthquakes of magnitude 3 or higher have occurred within 250 kilometers of the epicenter since 1950. This makes the magnitude 4.8 quake the largest in the area in recent history, surpassing even the notable 2011 Virginia earthquake, which also caused shaking in New York.
The earthquake’s mechanism is estimated to be strike-slip,a type of fault movement where two blocks of rock slide past each other horizontally. While the event caused concern and a flurry of social media activity, reports of significant damage remain limited. The rarity of such events in this region highlights the unpredictable nature of seismic activity, even in areas considered relatively stable.
Experts are continuing to analyze the data from this significant event to better understand the geological factors contributing to the earthquake and to assess any potential long-term implications for the region. The event serves as a reminder that even areas considered low-risk can experience significant seismic activity.

Earth Shakes Globe: From Vanuatu to New jersey, Powerful Tremors Highlight Seismic unrest
The Earth rumbled this week, unleashing a series of powerful earthquakes that stretched from the sun-drenched islands of Vanuatu to the bustling sidewalks of New York City. While geographically distant, these events serve as a stark reminder of the immense forces shaping our planet and the need for global seismic monitoring and preparedness.
In the early hours of tuesday (Japan time), the picturesque island nation of Vanuatu was jolted awake by a magnitude 7.3 earthquake. The tremor, occurring just 57 kilometers beneath the ocean surface, sent strong waves of energy rippling across the region.
“The shaking was intense, like nothing I’ve ever felt before,” said one resident of Port Vila, Vanuatu’s capital.
The quake triggered a tsunami, but the maximum wave height was only 0.25 meters, sparing the island nation from major coastal damage.
“Based on the epicenter’s depth and the mechanism, it appears the earthquake was caused by a rupture within the Australian Plate,” said Dr. Emily Carter, a seismologist at the USGS, citing preliminary analysis.
