Myths
Can Earthquakes Really be Predicted?
The history of earthquakes is nothing less than terrifying. Whether it’s the 1556 Shaanxi earthquake or something as recent as the 2023 Turkey–Syria earthquake, every major earthquake in the world involves destruction and death. For centuries, scientists, geologists, saints, and seers alike have searched for answers to one inevitable question: Can earthquakes be predicted? Let’s try to find out.
Myths about Earthquakes and Predicting Them
The phenomenon of earthquakes has long been attributed to mythical and otherworldly happenings. Thousands of years ago, the occurrence of an earthquake not only brought destruction but also paved the way for the fear of the unknown and faith in supernatural power.
The concept of an earthquake is often attributed to Poseidon, the god of the sea in Greek mythology. It is said that Poseidon uses his trident to shake the earth which causes earthquakes. Similar stories are found in Japanese mythology where the giant catfish Namazu causes earthquakes. According to Mongolian mythology, the earth is placed on the back of a giant frog. When the frog stumbles, it causes earthquakes.

But beyond the myths, there are also some common misconceptions about earthquake predictions. Unlike the myths, these aren’t quite outlandish and are often passed on as hard facts. Some of the common misconceptions regarding earthquake prediction include:
- Animals can predict earthquake - There are always advanced signs of earthquakes - Earthquake is preceded by sudden weather change - Planetary alignment influences earthquake - Increased seismic activity is a precursor for a large earthquake - A series of small earthquakes deters the chance of a large earthquake in a region.
Unfortunately, none of these concepts are true. There is no set pattern to earthquakes and neither does it have any identifiable precursors. And that brings us to the all-important question.

10 Dengue Myths Debunked: Here are the Facts
Dengue, often referred to as break-bone fever, poses a considerable risk. The world has witnessed its spread as an epidemic, affecting millions globally. Amid this global health concern, some myths surrounding dengue are leading to misinformation and misguided treatment approaches. This article is going to debunk 10 myths about dengue. Let’s clear up these misconceptions about this formidable mosquito-borne disease for effective prevention.
10 Misconceptions about Dengue
Dengue is Contagious
Dengue primarily spreads through the bite of infected Aedes mosquitoes. It is not a contagious disease. It is not transmitted through person to person contacts.
While dengue is not typically transmitted from person to person, there are exceptional circumstances to consider. For instance, an infected pregnant mother can pass the virus to her developing fetus. Additionally, transmission via blood products, organ donation, and transfusions, while extremely rare, is not entirely impossible.

Dengue Prevails in Rural or Developing Areas
This myth does not hold when examining the global reach of this infectious disease.
Dengue is not limited to any specific geographical or economic boundaries. Dengue can occur in any country where the Aedes mosquito species are present. This includes tropical and sub-tropical climates worldwide, encompassing both urban and semi-urban areas.
Children and Elderly Are Susceptible to Dengue
It's crucial to clarify that dengue can affect individuals of all ages, regardless of their age, gender, or socioeconomic status.
Dengue virus does not discriminate based on age. People of all age groups are susceptible to dengue infection, and this includes infants, children, teenagers, and adults. It's true that certain risk categories, such as children and the elderly, are more vulnerable due to their potentially weakened immune systems. However, even healthy individuals can contract dengue or develop severe symptoms.

Any Mosquito Can Carry Dengue Virus
In reality, dengue can only be transmitted through the bite of a female mosquito belonging to the Aedes Aegypti or the Aedes Albopictus species. This certain species is distinguished by its characteristic white markings on the legs. The transmission occurs when it bites an infected individual and subsequently bites a healthy and non-infected person. After an incubation period of about a week, the same mosquito can transmit the disease to another individual. It makes these particular mosquito species the primary vectors for dengue transmission.
Dengue Mosquitoes Only Bite During the Day
While it is true that dengue-spreading mosquitoes are more active during the daytime, their feeding habits can extend into nighttime hours. These mosquitoes are typically most active around two hours after sunrise and a few hours before sunset. However, they have been observed biting people at night, particularly in well-lit areas.
One of the risk factors for nighttime exposure to dengue mosquitoes is the presence of artificial lighting. These mosquitoes can be drawn to indoor environments, including offices, malls, indoor auditoriums, and stadiums that use artificial lights throughout the day and night.
