Natural Events in Indonesia and Neighboring Countries

Natural Events in Indonesia and Neighboring Countries – In Indonesia as well as in neighboring countries, we often encounter many incidents of natural incidents. Surely you’ve heard of disasters right? Natural disasters can be categorized as natural events. There are also those who call natural incidents as signs of nature. So what are natural signs? Natural phenomena are natural incidents that occur due to the effects of nature itself. Basically, natural incidents in Indonesia and natural incidents in neighboring countries have different sources of disaster, because the location of the country is also different.

Not all natural incidents are detrimental to humans because some are beneficial for human life. Categories of natural incidents that harm humans include floods, landslides, hurricanes, volcanic eruptions, storms, and earthquakes. As for natural incidents that are beneficial to humans, for example, dry, rainy, sunny, cold, hot, and cloudy. Now seeing the incident, this time I will discuss about natural incidents in Indonesia and natural incidents in neighboring countries. Here’s the full review.

Natural Events in Indonesia and Neighboring Countries

Every country has its own natural incidents. This is because it is always related to the appearance of the earth’s surface. The natural features in Indonesia and the natural features in neighboring countries that are members of ASEAN have similarities. This indicates that the natural signs are almost the same. It is the same with natural incidents in Indonesia and natural incidents in neighboring countries.

I have explained above that natural events are incidents whose events are influenced by nature. These natural events can be beneficial and harmful and even dangerous. Below are some natural incidents in Indonesia and natural incidents in neighboring countries. Here’s the explanation.

Natural Events in Indonesia

As we know, natural incidents in Indonesia are harmful or not harmful to human life. For natural incidents that are profitable are always used by the community in survival.

Natural Events That Do Not Harm Humans

Natural events in Indonesia that are included in the category of not harming humans, for example the change of seasons, the formation of dew, or the formation of rainbows.

Seasonal Change
Natural events in Indonesia are categorized as not detrimental, the first is the change of seasons. In Indonesia, there are two types of fever, namely rainy season fever and dry season fever. The occurrence of dry season fever in Indonesia is caused by the southeastern flu season wind blowing (from the dry Australian continent). The wind does not carry too much water vapor from the sea it has passed. This resulted in Indonesia experiencing a dry season fever from April to October.

Natural events in Indonesia such as rainy season are caused by the blowing of cold winds from the northwest (Indian Ocean). The wind can carry a lot of water vapor from the Indian Ocean. This resulted in Indonesia experiencing a rainy season fever from October to April. Even so, the rainy season fever and the dry season fever often experience a shift in time. Sometimes the rainy season fever is longer than the dry season fever and vice versa. The time shift is caused by changes in temperature on the Pacific maritime surface. Both issue fevers were influenced by uncertain atmospheric conditions or often referred to as the “Transitional Season”. The duration of the transitional issue fever is approximately one to two months.

Formation of Dew
Natural events in Indonesia are categorized as not detrimental, the next is the formation of dew. The formation of dew comes from the air on the ground surface which becomes cooler. The excess water vapor creates condensation around objects that are close to the ground. The creation of good dew on a clear night. Dew formation is also very good when the humidity is high.

Rainbow Forming
Natural events in Indonesia are categorized as not detrimental, the next is the formation of rainbows. Rainbow is a natural phenomenon that generally occurs after rain. The formation of a rainbow in terms of science is very simple. This is because rainbows are formed from the refraction of light. The refracted light will change direction. Then the light will be scattered and refracted by raindrops to form a rainbow.

Natural Events That Harm Humans

Natural events in Indonesia can also harm humans. Such events include floods, droughts, volcanic eruptions, earthquakes, forest fires and landslides.

Drought and Flood
Natural events in Indonesia in the first category of adverse events are droughts and floods. In Indonesia, drought often occurs during the dry season and floods during the rainy season. Even flood events have become a regular in Indonesia, especially in the DKI Jakarta area. These disasters are caused by natural factors and human activities such as river narrowing, building construction and tree cutting.

Erupting volcano
Natural events in Indonesia, the next category of adverse events is volcanic eruptions. In Indonesia there are about 130 mountains. This is because Indonesia is included in the meeting area between 3 large tectonic plates such as the Pacific plate, the Indo-Australian plate, and the Eurasian plate. The collision between the Indo-Australian and Eurasian plates is on the coasts of Java, Nusa Tenggara and Sumatra. Meanwhile, the collision of the Indo-Australian plate with the Pacific is in North Maluku and northern Irian. The meeting that occurs between the plates causes faults and folds which eventually form cracks. These cracks spit out a magma. Magma is a hot clay substance that can emerge towards the earth’s surface. Volcanoes that erupt cause damage to the environment, for example hot clouds, lava floods, piles of sand, black fires and piles of volcanic powder.

Natural events in Indonesia such as volcanic eruptions have recently occurred, for example in Mount Egon, East Nusa Tenggara. Mount Egon erupted in April 2008 to create a cloud of dust 4,000 meters high. This disaster caused the village around Mount Egon, namely the residents of Sikka, to panic. Then there was the eruption of Mount Merapi in 2010 which killed about 165 people. Then in 2012 the eruption of Mount Soputan, North Silawesi.

Earthquake
Natural events in Indonesia, the next category of adverse events are earthquakes. Earthquakes are reliable vibrations caused by natural events such as volcanic eruptions, the collapse of mountain slopes and the faulting of the earth’s crust. Areas that often experience earthquakes are usually around volcanoes. This is because the route has a lot of debris, faults and volcanoes erupting. In Indonesia, there are several earthquake-prone areas based on the records of the Directorate of Volcanology and Geological Hazard Mitigation (DVMBG) of the Ministry of Energy and Mineral Resources which you can see in the map below:

Map of Earthquake Prone Areas in Indonesia

Below are some of the earthquake events that have hit Indonesia, namely:

  1. Earthquake on March 28, 2005 in Sumatra with a magnitude of 8.7 SR. The earthquake was centered beneath the surface of the Indian Ocean.
  2. Earthquake on December 26, 2004 in the Indian Ocean. The quake killed about 230,000 people in eight countries and created tsunami waves with a height of 30 meters.
  3. Earthquake on January 4, 2009 in Papua with a magnitude of 7.6 on the Richter Scale.
  4. Earthquake on September 30, 2009 in West Sumatra, to be precise 50 km northwest of the city of Padang.
  5. Earthquake on 12 September 2007 in Bengkulu with a magnitude of 7.9 SR.
  6. An earthquake on July 17, 2006 in Java with a magnitude of 7.7 on the Richter Scale. The earthquake caused houses around the southern coast of Java to be destroyed due to the tsunami which was almost 2 meters high.

Forest fires
Natural events in Indonesia, the next category of adverse events is forest fires. Forest fires can be caused by human activity or naturally (friction of dry tree branches in the dry season). However, in Indonesia, forest fires are often caused by burning forests as agricultural land. Trees are cut down and burned with the intention of making it easier to clean them. Forest fires are difficult to overcome if there is a forest that contains a lot of wood in the soil. Even for weeks on end fires can occur, especially if carried away by the wind.

Natural events in Indonesia such as forest fires can cause air pollution. Even the smoke from the fire can cause respiratory problems for the surrounding population. It will also disrupt the flight path traversed by aircraft.

Landslide
Natural events in Indonesia, the next category of adverse events is landslides. Indonesia has a type of soil originating from volcanic eruptions. Therefore, most of the composition of the soil is clay and a little sand. This type of soil is a fertile soil type. Even so, there is a high potential for landslides to occur when the rainy season comes. This disaster will continue to hit if there are no perennials that have strong roots. In Indonesia, there are around 918 landslide-prone areas that spread across West Java, North Sumatra, Central Java, Yogyakarta, Kalimantan and West Sumatra.

Natural Events in Neighboring Countries

Next I will explain some natural incidents in neighboring countries, namely:

Cyclone Nargis in Myanmar

The first natural event in neighboring countries was Cyclone Nargis in Myanmar. The wind has a speed of up to 190 km / hour. Typhoon Nargis devastated five areas in Myanmar in May 2008 namely Bago, Mon, Yangon, Karen and Irawaddy. The typhoon also killed 77,700 people and of them 42,000 were missing. The wind also caused damage to shops, public accommodation and houses. Typhoon Nargis caused the central power outage and landslides. This disaster is one of the worst events in Asia.

Storm in Vietnam

The next natural event in neighboring countries is a typhoon in Vietnam. In 2006 there was a tropical typhoon that killed hundreds of people in Vietnam. The types of typhoons that hit northern Vietnam were Typhoons Lekima, Toraji, Chancu, and Pabuk. There were 500 thousand people who were deliberately evacuated from the coast in October 2007. This was done to anticipate the attack of typhoon lekima. In 2007 there were 86 people died in Vietnam and more than 600 people died in 2006.

Floods in Malaysia

The next natural event in neighboring countries is flooding in Malaysia. Malaysia is a country that is close to Indonesia and is divided into two parts, namely East Malaysia and West Malaysia. East Malaysia is connected to the island of Borneo. While West Malaysia is on the Malacca Peninsula. Every November-February, the country of Malasya is traversed by monsoon winds which cause flooding. Malaysia has experienced the most reliable flooding in the last hundred years, in 2006.

Tropical Storms and Volcano Eruptions in the Philippines

The next natural event in neighboring countries is a tropical cyclone and volcanic eruption in the Philippines. In the Philippines, there are two mountains that often erupt, namely Mount Parker and Mount Mayon. The eruption of Mount Mayon occurred on July 17, 2006 and Mount Parker caused a mud flood in 1995 because the crater was hollow. Then a tropical typhoon that hit the Philippines occurred in September-November. The types of typhoons that are popular in this country are tropical typhoons fengshen and durian. This storm killed 37 people and devastated the Philippines in 2006.

These are some natural incidents in Indonesia and natural incidents in neighboring countries that I can share. Hopefully this article can add to your insight. Thank you.
