Krakatoa/ Krakatau
Krakatoa, Indonesian Krakatau, volcano on Rakata Island in the Sunda Strait between Java and Sumatra, Indonesia. Its explosive eruption in 1883 was one of the most catastrophic in history. Krakatoa lies along the convergence of the Indian- Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity.
Sometime within the past million years, the volcano built a cone-shaped mountain composed of flows of volcanic rock alternating with layers of cinder and ash. From its
base, 1,000 feet (300 metres) below sea level, the cone projected about 6,000 feet (1,800 metres) above the sea. Later (possibly in 416 CE), the
mountain’s top was destroyed, forming a caldera, or bowl-shaped depression, 4 miles (6 km) across. Portions of the caldera projected above the water as four small islands:
Sertung (Verlaten) on the northwest, Lang and Polish Hat on the northeast, and Rakata on the south. Over the years, three new cones were formed, merging into a single island.
The highest of the three cones rose to 2,667 feet (813 metres) above sea level.
The only confirmed eruption prior to 1883 was a moderate one in 1680. On May 20, 1883, one of the cones again became active; ash-laden clouds reached a height of 6 miles (10 km), and explosions were heard in Batavia (Jakarta), 100 miles (160 km) away, but by the end of May the activity had died down. It resumed on June 16 and became paroxysmal by August
26. At 1:00 PM of that day the first of a series of increasingly violent explosions occurred, and at 2:00 PM a black cloud of ash rose 17 miles (27 km) above Krakatoa. The climax was reached at 10:00 AM on August 27, with tremendous explosions that were heard 2,200 miles (3,500 km) away in Australia and propelled ash to a height of 50 miles (80 km).
Pressure waves in the atmosphere were recorded around the Earth. Explosions diminished throughout the day, and by the morning of August 28, the volcano was quiet.
Small eruptions continued in the following months and in February 1884.
The discharge of Krakatoa threw into the air nearly 5 cubic miles (21 cubic km) of rock fragments, and large quantities of ash fell over an area of some 300,000 square miles (800,000 square km). Near the volcano, masses of floating pumice were so thick as to halt ships. The surrounding region was plunged into darkness for two and a half days because of ash in the air. The fine dust drifted several times around the Earth, causing spectacular red and orange sunsets throughout the following year.
After the explosion, only a small islet remained in a basin covered by 600 feet (250 metres) of ocean water; its highest point reached about 2,560 feet (780 metres) above the surface. As much as 200 feet (60 metres) of ash and pumice fragments had accumulated on Verlaten and Lang islands and on the remaining southern part of Rakata. Analysis of this material revealed that little of it consisted of debris from the former central cones: the fragments of old rock in it represented less than 10 percent of the volume of the missing part of the island. Most of the material was new magma brought up from the depths of the Earth, most of it distended into pumice or completely blown apart to form ash as the gas it contained expanded. Thus, the former volcanic cones were not blown into the air, as was first believed, but sank out of sight, the top of the volcano collapsing as a large volume of magma was removed from the underlying reservoir.
Krakatoa was apparently uninhabited, and few people died outright from the eruptions. However, the volcano’s collapse triggered a series of tsunamis, or seismic sea waves, recorded as far away as South America and Hawaii. The greatest wave, which reached a height of 120 feet (37 metres) and took some 36,000 lives in nearby coastal towns of Java and Sumatra, occurred just after the climactic explosion. All life on the Krakatoa island group was buried under a thick layer of sterile ash, and plant and animal life did not begin to reestablish itself for five years.
Krakatoa was quiet until December 1627, when a new eruption began on the seafloor along the same line as the previous cones. In early 1628 a rising cone reached sea level, and by 1630 it had become a small island called Anak Krakatau (“Child of Krakatoa”). The volcano has been active sporadically since that time, and the cone
has continued to grow to an elevation of about 1,000 feet (300 metres) above the sea.

Human Education
Human education is a critical instrument in their lives. It is a significant distinction between a civilized and an undisciplined individual. Even if the country’s literacy rate has increased in recent years, more individuals need to be made aware of the importance of education. Every child, whether a male or a girl, must attend school and not drop out. Education is beneficial not just to the individual but also to society. A well- educated individual is a valuable asset to society, contributing to its social and economic development. Such a person is always willing to assist society and the country.
It is true to say that education is a stairway to a person’s and a nation’s achievement.
Education makes a person productive, allowing him or her to contribute to society in a positive way. It teaches us how to face many challenges and conquer them. A well- educated individual understands how to act in a polite and non-offensive manner. It shows us how to live a disciplined life while yet making a respectable living. Our future is built on the basis of education. Education is also the sole weapon that may be used to combat numerous issues such as illiteracy, poverty, unemployment, and so on. A person’s education makes them more sensitive to the predicament of their fellow beings. A well-educated individual not only comprehends the issues but also possesses the essential abilities to address them.
An educated individual possesses competent skills and is more capable than someone who is uneducated. However, it is incorrect to think that education alone ensures success. Indeed, success necessitates a solid education, as well as devotion, attention, and hard effort. An educated individual is more sensible and capable of rational thought.
Education allows a person to become self-sufficient. An educated individual does not rely on others and is capable of meeting his or her own requirements. A well-educated person also educates their family, and education benefits, not just the individual but also society and the nation. Education has a significant influence on our outlook, making us more optimistic about life and its objectives.
