JAKARTA – A 5.6 magnitude earthquake caused more than 160 deaths and hundreds of injuries as buildings collapsed. Residents fled for their lives. Indonesia’s Hauptinsel of Java.
On Tuesday morning, the bodies of victims in Cianjur, the country’s most populous province, were being pulled from the rubble. West Java And some 217km (135 mi) south of Jakarta, the capital. A large number of people are still unaccounted for.
Experts say that while the magnitude of the earthquake would be expected to cause minimal damage to buildings, other structures could suffer minor damages. quake The damage was caused by inadequate infrastructure that can’t withstand earthquakes.
Here is a closer look into the earthquake and reasons it caused. so much devastation:
The U.S. Geological Survey stated that quake Late Monday afternoon, 5.6 magnitude was measured and struck at 10 km (6.2 miles) depth.
This is a rare case where quakes of this magnitude don’t cause significant damage to existing infrastructure. However, the agency reminds us that “There is not one magnitude above which damage will occur. It depends on other variables, such as the distance from the earthquake, what type of soil you are on, building construction” These and other factors.
In Indonesia, many buildings were destroyed, including Islamic boarding schools and hospitals, as well as other public facilities. Roads and bridges were also damaged, and some parts of the region were without power.
Experts stated that the factors responsible for the destruction were the proximity to fault lines, depth of the earthquake and the inability to construct buildings using earthquake-proof methods.
“Even though the earthquake was medium-sized, it (was) close to the surface … and located inland, close to where people live,” Gayatri MarliyaniUniversitas Gadjah Mada’s assistant geology professor, Yogyakarta (Indonesia). “The energy was still large enough to cause significant shaking that led to damage.”
Marliyani said that the worst affected area is near several faults.
A fault is defined as a spot with a long crack in the rock that forms its surface. earth. An earthquake can occur on any of these faults. The rock on the fault’s one side will slip relative to the other.
“The area probably has the most inland faults compared to the other parts of Java,” said Marliyani.
She said that although some faults are well-known, there are many active faults in the region that aren’t well understood.
Many of the buildings in the area are not also built with this material. quakeAccording to Danny Hilman Natawidjaja a geologist at the Indonesian Institute of Sciences Geotechnology Research Center, he said that -proof designs further contributed to the damage.
“This makes a quake of this size and depth even more destructive,” He said.
This country, home to more than 270million people, is regularly struck by earthquakes and volcanic eruptions. Its location in the Pacific Basin (also known as the Arc of Volcanoes) means that it is very close to the fault lines and fault lines of the Pacific Basin. “Ring of Fire.” It covers approximately 40,000 km (25,000 miles), and is the location of most earthquakes in the world.
Many of Indonesia’s Minor earthquakes cause very little or no damage. There have been also deadly earthquakes.
February saw a magnitude 6.2 earthquake that killed at most 25 people in West Sumatra and injured over 460 more. In January 2021, more than 100 people were killed and nearly 6,500 were injured in West Sulawesi by a magnitude 6.2 earthquake.
