Earthquake Alert Message by Don Prince

The day before yesterday at 10:15 PM in Kathmandu, I was about to sleep, a 4.6 MS suddenly stroke with breath taking tremor and highly alerting sound. Just for a while I forgot that it could be only a momentary aftershock. But I did not panic. Nor did anyone in my family run away. I suggested everyone that there was nothing to get afraid. It was just an aftershock which was a bit stronger. I also said that the epicenter must have been inside the city. So it felt strongly. Then all of us slept calmly. But in the morning I came to know that some people in the city had spent whole night out of the house getting scared with this aftershock. So I decided to write this article to convey my important message to them so that they do not face such problem next time.

There are 3 reasons I  guaranteed it was a normal jolt having epicenter in Kathmandu:

1. It felt strongly
As aftershock is felt stronger near the epicenter, this strongly felt jolt gave a hint that it must be around the city. It was taken seriously by media and public in Kathmandu. But there was nothing special to highlight. By the way aftershocks of around 4.6 were going on continuously in other parts of the rupture area. However this aftershock terrorized people in Kathmandu. Because its epicenter was inside Kathmandu.

2. It gave experience of sound
We do not hear the sound of earthquake itself but we hear the sound of physical things on the earth which are moved by earthquake. Big earthquake gives sound experience everywhere. But small aftershock can make us hear sound only if we are near the epicenter because small aftershock is stronger near the epicenter only. And it is weaker in the places far from the epicenter. As the aftershock gave sound experience, chances were high that it was in or near the city.

3. Time was too short
If it had been an independent earthquake, it could have lasted for longer time. But it was for a short time. Similarly it slowed down exponentially and gave experience of descending shaking for more time which is the strong evidence that aftershock began and ended inside the city.

The day before yesterday's aftershock was not a surprising attack for me. In fact, I was waiting for a 4.9 MS to match my self developed statistic which I am going to release after aftershocks completely stop in Nepal. According to my unexposed theory, an aftershock of around 4.9 is still inevitable in near future. If it does not happen, the upcoming aftershock will not exceed 4.6. And it will modify my upcoming law, i.e. ''Prince's Law of Aftershocks''.

So, I, through this article, want to spread the message that unlike day before yesterday, there is high chance that an aftershock of around 4.9 MS or 4.4 MS is going to strike Nepal in near future which is not dangerous. People far from the epicenter may not feel it but it can terrorize the people nearby the epicenter. If you experience it, do not run away blindly inviting unwanted accident. Stay inside till you confirm that it is not a small aftershock but an independent earthquake of other part of Nepal or another strong aftershock. And you can do it by waiting at least 5 seconds inside the house. At last, I am happy to pour my opinion that the aftershocks of Nepal are settling exponentially day by day.

Is Volcano Possible in Nepal?

When fear and ignorance rent on mind, rumour becomes a guest for a long time. Nepal experienced it in past few months. It was natural that people believed the rumours of earthquake predictions. Because earthquake was hitting Nepal from the time immemorial. And people had stored less information about earthquake. But I wonder how easily people ran after the rumours of volcano in Nepal whereas there had never ever been event of any volcanic eruption in the past.

‘Can volcano erupt in Nepal?’ If you ask this question to anyone who has some knowledge of volcano, you will get answer something like this:
‘’No, volcano can not erupt in Nepal.’’

If you ask why volcano can not erupt in Nepal, you can get 2 types of answers:
1. because Nepal is a mountainous country
2. because there is no sea in Nepal

Both answers give same but complete meaning. However you need to know why volcano can not erupt in a mountainous country or in a country like Nepal which lacks sea.

According to Mr. Raj Maharjan, the science and environment teacher of Abhiyan Public School, Balaju, Kathmandu, volcano is not possible in and around Nepal because of the condition that Indian plate is over thrusting Eurasian plate. When two continental plates overlap, the originated volcano can not come out. It collapses on its way within the crust forming the igneous rock.


Mr. Sudan Lamichhane, the science teacher of Blue Wren School, Kalanki, Kathmandu says that Volcano can erupt only in the country which is on the oceanic plates not in the country like Nepal where there is no sea at all. Volcano can occur above the subduction zone. Subduction zone is the zone where oceanic plate overlaps into continental plate. But Nepal does not lie above the subduction zone. So volcano is not possible in Nepal.

So what is conclusion? I think both arguments are acceptable and they support same concept. In my personal opinion, oceanic plate has less mass and continental plate has more mass. In subduction zone, being one continental plate and another oceanic plate, mass is thin and volcanic magma easily comes outside causing volcanic eruption. But if there are both continental plates overlapping, the mass are so thick that the volcanic magma can’t come outside and it cools down and hardens. As a result it forms unique type of rock, i.e., igneous rock. And there is no volcano above the crust.

At last I want to say that ‘Why is volcano not possible in Nepal?’ is a tough question. I did not find the answer of this question even in Google Search. So I created this post trying to find out the answer. The answers given above may or may not be right. I have published it in order to get review as well as start discussion among the intellectual community. If you agree with our findings please like or share this article. If you have different opinion, do not forget to comment below to share your knowledge.

Why Nepal is Still Being Hit by Aftershocks

Aftershocks are forecast-able not predictable. This means that current science can't calculate exact time, magnitude and intensity of aftershocks. Nor can it say when it stops. However it's pretty simple to know how it stops.

Aftershocks in Nepal are still active. This is definitely surprising. It is because of the amazing nature of the mainshock. So there is no need to worry. They are normal. If this earthquake and aftershocks had not been of such nature, we would have faced much shaking during the mainshock and that could have been much devastating. Anyway we want to see these aftershocks stopped. So here rises the question how to know if aftershocks stopped?

There are 3 conditionals to be fulfilled to confirm aftershocks stopped:
1. Aftershocks disappeared for longer time
It's pretty easy to say aftershocks stopped if there is no aftershock more than 4 M for longer time.

2. Earthquake occurred in other than the rupture zone
If aftershocks are not taking place for longer time and regular earthquake took place in other than the rupture zone, this is strong evidence to say that aftershocks have stopped.

But there is an important thing to remember that aftershocks can occur even nearby {a bit farther} the rupture zone due to the stress created by the ongoing aftershocks. So only the aftershocks very far from the rupture zone should be taken as an independent earthquake.

3. Aftershocks are absent after the independent earthquake
If aftershock stroke again after an independent earthquake, It is sad to say that this is not the end of the aftershocks. They should not appear again.

If those 3 levels are completed, we can believe that the earthquake sequence of Nepal has gone to the pre earthquake level and we won't be facing aftershocks later.
