Understanding the Causes of the 2024 Noto Peninsula Earthquake

The Noto Peninsula in Japan experienced a devastating earthquake on January 1st, 2024, leaving a significant impact on the surrounding areas. This earthquake, with a magnitude of 7.6, recorded a maximum intensity of seven in the Shika Town District of Ishikawa Prefecture. To properly understand the causes and circumstances surrounding this earthquake and be more prepared in the future, it is crucial to delve into its detailed causes and key points.

Causes of the 2024 Noto Peninsula Earthquake

The Noto Peninsula Earthquake

The earthquake that struck the Noto Peninsula on January 1st, 2024, was part of the Noto cluster earthquakes that have been occurring in the region since December 2020. With its epicenter in the Noto Peninsula of Ishikawa Prefecture, this earthquake shook the area, leading to extensive damage. However, the cause behind these cluster earthquakes is not yet fully understood.

Noto Cluster Earthquakes

The Noto Peninsula has been experiencing cluster earthquakes, with seismic activity particularly active in the waters North to east of the region. This seismic activity intensified after a magnitude 6.5 earthquake in May 2023 in the northern part of the eastern area. The movement of fluids rising from underground, expanding the Earth's crust, is one hypothesis behind these cluster earthquakes.

Hypothesized Causes of Cluster Earthquakes

Observations in Suzu City, Ishikawa Prefecture, showed the ground rising by about 4 cm, indicating a mechanism involving the movement of water from underground. The presence of water and its weakening effect on the rock mass is believed to trigger these reverse fault-type earthquakes. Additionally, surface and seawater infiltrating along deep underground faults may create fossil seawater pockets, further contributing to the weakening of the rock mass and seismic activity.

The Noto Peninsula's Deformation and Presence of Water

Crustal Deformation and Uplift of the Noto Peninsula

The Noto Peninsula is characterized by strong compressive forces causing crustal deformation, leading to its uplift. These movements and deformations play a significant role in the occurrence of reverse fault-type cluster earthquakes in the region.

Electrical Conductivity and Presence of Water

An area near the epicenter of the Noto Peninsula earthquake showed properties conducive to electrical conductivity, suggesting the presence of water. The presence of water in gaps within the rock mass is yet another factor weakening the structure and triggering earthquakes.

Weakening of Rock Mass and Triggering of Earthquakes

It is important to understand that the Noto Peninsula earthquake is likely not caused by magma intrusion but rather by the underground water weakening the rock mass. Dangerous cluster earthquakes may continue to occur in this region, requiring close monitoring and preparedness.

Continued Likelihood of Cluster Earthquakes

Monitoring Seismic Activity in Japan

In Japan, it is crucial to monitor seismic activity along plate boundaries closely. The Nankai Trough, Japan Trench, and Sagami Trough are areas that could potentially generate large-Scale earthquakes in the future. Continual monitoring and research are necessary to improve prediction models and mitigate the impact of earthquakes.

Potential for Large-Scale Earthquakes in the Future

Japan has historically experienced various magnitudes of earthquakes, resulting in significant damage and loss of life. Predictions indicate the likelihood of large-scale earthquakes, such as the Nankai Trough earthquake and those along the Kuril Trench and Japan Trench. These earthquakes could have a devastating impact, causing loss of life and significant damage to infrastructure.

Historical Data on Earthquakes in Japan

Major Damaging Earthquakes in the Seas near Japan

Japan has witnessed several major damaging earthquakes in the seas surrounding it, both recent and from the past. These earthquakes serve as a reminder of the potential for seismic activity and the importance of preparedness. For example, the Noto region of Ishikawa Prefecture experienced a magnitude 5.9 earthquake in 2023, resulting in casualties and injuries.

Predicted Large-Scale Earthquakes in the Future

The future holds the possibility of large-scale earthquakes in Japan, as supported by predictions. The Nankai Trough earthquake, earthquakes along the Kuril Trench and Japan Trench, and a potential direct hit earthquake under the capital are predicted with a 60 to 70% chance of occurring within the next 30 years. These earthquakes have the potential for a significant number of deaths and detrimental economic impact.

Impact and Preparations for Earthquakes

Impact of the 2024 Noto Peninsula Earthquake

The 2024 Noto Peninsula earthquake had a profound impact on the region. It led to widespread damage, temporary water outages, power outages, and even casualties. Tourist attractions, public facilities, accommodations, and exhibition halls were also affected. The earthquake served as a reminder of the possibility of ground loosening and damage in adjacent areas, requiring continued monitoring and preparedness.

Preparations for Evacuations and Basic Necessities

To prepare for earthquakes, it is essential to have a plan for evacuations. Basic necessities include water supply, food, essential documents, emergency contact lists, and disaster prevention items such as helmets and rain gear. First aid supplies, blankets, and hygiene products should also be prepared. Being well-equipped and informed helps minimize the impact of earthquakes.

Knowledge and Preparedness for Earthquakes Worldwide

While Japan is particularly susceptible to earthquakes, the possibility of major earthquakes exists worldwide. Therefore, having the correct knowledge and preparedness for earthquakes is essential regardless of location. Accurate prediction of earthquakes may not be possible, but with proper preparation and knowledge, their impact can be minimized.

Conclusion

The 2024 Noto Peninsula earthquake serves as a reminder of the seismic activity that can significantly affect our daily lives. By understanding its causes, the deformation of the Noto Peninsula, and the continued likelihood of cluster earthquakes, we can better prepare and mitigate the impact of future earthquakes. It is important to monitor seismic activity, be aware of potential large-scale earthquakes, and make necessary preparations for a safer life.
