2.1. Tectonic Plate Boundaries

In case of just for an example, maybe we can see that in case of earthquake; earthquake occurs along the boundaries of the tectonic plates of the earth crust. this is one hazard and when this is the source of the hazards and when this happens, we can see that these plates come in contact with each other and the pressure builds up an earthquake occurs.

Earthquakes primarily occur at the boundaries of tectonic plates. These plates are massive pieces of the Earth's crust that float on the semi-fluid layer beneath them. When these plates interact—either colliding, sliding past each other, or moving apart—they can build up tension. Eventually, this tension is released in the form of an earthquake. Understanding this relationship between the plates and earthquakes is crucial for disaster preparedness.

Imagine the tectonic plates like two cars bumping into each other. Initially, they may gently tap, creating a little damage, but if they collide with enough force, they can cause a significant crash—similar to how pressure builds and releases in an earthquake.

Now, this is just simply a physical event, this is you can see some of the distribution of the tectonic plates in some places and this hazard; this earthquake hazard, we have 3 processes; physical process that can trigger this hazard. One is that convergent boundaries; when two plates collide together this created the Himalayan mountain so, one way of the event of earthquake that can happen when two plates are colliding each other. Another was is the subductions; there is when one oceanic plate goes under the land plate and created this kind of earthquake. And another one is the divergent one, when two plates are moving apart, this can also cause earthquake. And this is we call divergent region.

There are three main types of tectonic plate boundaries that can lead to earthquakes: 1) Convergent boundaries occur where two plates collide, which can create mountains like the Himalayas, and lead to significant earthquakes; 2) Subduction zones happen when an oceanic plate is forced under a continental plate, often leading to powerful earthquakes; and 3) Divergent boundaries are where two plates move apart from each other, which can also cause earthquakes. Each type of boundary has distinct geological processes that influence the occurrence of earthquakes.

Think of tectonic plates as puzzle pieces. When you push two pieces together at a corner (like a convergent boundary), they can create a peak, just like a mountain. If one piece slides underneath the other (subduction), it can create a deep trench and cause tremors. When pieces are drawn apart (divergent), it’s like ripping apart a piece of paper, which can also lead to breaks and quakes.

Now when we are talking about hazards, can we avoid hazard? No, historically hazards were there, it is there and it will remain. So, we cannot avoid hazard basically.

Hazards like earthquakes are an inherent part of our planet's geological processes. They have existed throughout Earth's history and will continue to occur. Rather than trying to avoid natural hazards (which is impossible), the focus should be on understanding them and mitigating their impacts through preparedness and response strategies.

It's like living near a large, active volcano. You can't stop the volcano from erupting, but you can have an evacuation plan in place, monitor volcano activity, and educate the community about what to do in case of an eruption, minimizing risks.
