The Geology of Japan- Week 1&2
Introduction:
Hazards, disasters, and catastrophes:
- Hazard: A hazard is a potential threat that can cause harm to people, property, or the environment. Hazards can be natural, like earthquakes or hurricanes, or human-made, such as chemical spills or industrial accidents.
Disaster: When a hazard materializes and causes significant damage, disruption, or loss, it becomes a disaster. Disasters occur when the impact of a hazard exceeds a community's ability to cope using its own resources, leading to a need for external assistance.
-
A catastrophe: an extreme form of disaster with far-reaching and long-lasting impacts. These events cause such extensive damage and disruption that they overwhelm local and even national capacities, necessitating international aid and long-term recovery efforts. An example is the 2011 earthquake and tsunami in Japan, which not only caused immediate widespread devastation but also led to the Fukushima nuclear disaster, with effects still felt years later.


Tectonic Plates
Japan is situated at the convergence of four major tectonic plates: the Pacific, North American, Eurasian, and Philippine Sea plates. This complex tectonic setting places Japan directly on or near several plate boundaries, making it one of the most seismically active regions in the world. Pbs.orgProximity to Plate Boundaries:
-Pacific Plate and North American Plate: long the
eastern coast of Japan, the Pacific Plate is subducting beneath the North
American Plate at the Japan Trench. This subduction zone is responsible for
frequent and powerful earthquakes.
- Philippine Sea Plate and Eurasian Plate: To the south,
the Philippine Sea Plate is subducting beneath the Eurasian Plate along the
Nankai Trough. This region is also highly active, with a history of megathrust
earthquakes and associated tsunamis. Iris.edu
Recent Events:
In January 2025, a magnitude 6.9 earthquake struck Japan's southwestern Kyushu region, triggering a tsunami advisory. While the advisory was later lifted and no significant damage was reported, this event underscores the ongoing seismic risks associated with Japan's tectonic setting. Thescottishsun.co
Hey ! For starters I love the theme and creativity you’re portraying in your blog. After reading your post I definitely learned a lot about Japan’s geographic location. Although it is unfortunate how Japan is in a serious hot zone for misfortune.
ReplyDeleteGreat job with your blog. I enjoyed reading and learning about the geology of Japan. I had no idea how frequently Japan had to be concerned about Tsunamis. I’m eagerly looking forward to exploring more of Japan through your blog.
ReplyDeleteGood information!- Please create a new post each week we blog instead of adding to the previous one. Thank you.
