SUMMARY

The 5.6 magnitude earthquake struck 18 km WSW of Ciranjang-hilir, Indonesia, on November 21, 2022, at 06:21:10 UTC. The earthquake, occurring at a shallow depth of 10 km, resulted in significant damage in the city of Cianjur, with at least 56 fatalities and hundreds injured. Emergency services responded swiftly, treating victims outside hospitals as panic spread to Jakarta, where high-rises swayed and evacuations occurred. The discussion highlights the need for improved building standards in earthquake-prone regions, drawing a comparison to Chile's resilient construction practices.

PREREQUISITES
  • Understanding of seismic activity and earthquake measurement scales
  • Knowledge of emergency response protocols in disaster situations
  • Familiarity with building codes and construction practices in earthquake-prone areas
  • Awareness of the geographical and geological context of Indonesia
NEXT STEPS
  • Research seismic building codes and standards in earthquake-resistant architecture
  • Explore emergency management strategies for urban areas during natural disasters
  • Investigate the geological features of the Java region and their impact on seismic activity
  • Learn about the technologies used in earthquake prediction and monitoring
USEFUL FOR

This discussion is beneficial for urban planners, civil engineers, emergency responders, and anyone involved in disaster preparedness and building safety in earthquake-prone regions.

City of Cianjur had significant damage, and effects felt in Capital City of Jakarta.

CIANJUR, Indonesia (AP) — A strong, shallow earthquake toppled buildings and collapsed walls on Indonesia’s densely populated main island of Java on Monday, killing at least 56 and injuring hundreds as people rushed into the streets, some covered in blood and white debris.

Emergency workers treated the injured on stretchers and blankets outside main hospitals, on terraces and in parking lots. Many included children, some of whom were given oxygen masks, IV lines and were being resuscitated.

“I fainted. It was very strong," said Hasan, a construction worker who is being treated at the Cianjur Regional Hospital. “I saw my friends running to escape from the building. But I was too late to get out and was hit by the wall.”

Residents, some crying with children in their arms, fled damaged homes after the magnitude 5.6 quake shook the Cianjur region in West Java province in late afternoon, at a depth of 10 kilometers (6.2 miles). It also caused panic in the greater Jakarta area, where high-rises swayed and some were evacuated.

The deaths and injuries are horrible news of course, but they are also preventable. I'm currently living in Chile, where earthquakes are commonplace. The Chileans have learned to build buildings that withstand earthquakes. A magnitude 5.6 hardly makes the news, and no buildings are damaged.
