37 B4 Bangunan terdampak gempa di Jepang

Summary

A major earthquake with a magnitude of 7.6 hit Japan's Ishikawa Prefecture, triggering a tsunami warning. Despite the devastation, Japan’s earthquake preparedness, including early warnings via mobile alerts, helped minimize casualties. In contrast, Indonesia's recent earthquake in Sumedang, though smaller in magnitude, caused panic and damage due to its shallow depth. Japan's advanced systems, like quake-resistant buildings and automatic shutdowns of transport and utilities, are highlighted as examples for Indonesia, which is still developing its own earthquake early warning system. The importance of earthquake-resilient infrastructure is emphasized for reducing casualties.

Takeaways

• 😀 A strong earthquake with a magnitude of 7.6 hit Ishikawa Prefecture, Japan, on January 1, 2024, causing significant damage.
• 🌊 A tsunami warning was issued for the western coast of Honshu to Hokkaido, as well as neighboring countries like Russia, North Korea, and South Korea.
• 🔥 A building in Wajima city, Ishikawa, caught fire due to the earthquake's aftermath, causing additional destruction.
• 🏚️ The earthquake severely affected towns like Wajima, Suzu, Nanao, and Anazimo, with widespread building collapses and cracked roads.
• ⚠️ Indonesia experienced a 4.8 magnitude earthquake in Sumedang, West Java, which caused panic despite being of lower magnitude.
• 🚑 The Sumedang earthquake caused significant panic, with residents evacuating to temporary shelters to avoid aftershocks.
• 🔔 In contrast to Indonesia, Japan has an effective earthquake warning system, with alarms sent to citizens' phones, allowing them to prepare before the quake strikes.
• 🧑‍💻 In Japan, even with strong shaking, many people remain calm, relying on warning systems and preparedness measures.
• 📱 Indonesia is working on an Earthquake Early Warning System (EEWS), though it is still in development and not yet implemented nationwide.
• 🏢 In Japan, infrastructure such as mass transit and utilities automatically shuts down during an earthquake to prevent further damage, which has yet to be fully implemented in Indonesia.
• 🏗️ One of the key lessons from Japan is the importance of earthquake-resistant buildings. In Indonesia, only about 10% of cities have earthquake-resistant building regulations, putting the population at risk in case of a major quake.

Q & A

What was the magnitude of the earthquake that hit the Ishikawa Prefecture in Japan on January 1, 2024?

The earthquake that hit Ishikawa Prefecture in Japan on January 1, 2024, had a magnitude of 7.6.

What was the immediate warning issued after the earthquake in Japan?

A tsunami warning was issued for the western coast of Honshu Island and Hokkaido, and similar warnings were issued for neighboring countries, including Russia, North Korea, and South Korea.

What were some of the visible damages caused by the earthquake in Japan?

The earthquake caused significant destruction in several cities like Wajima, Suzu, Nanao, and Anazimo, with damaged buildings, homes, and cracked roads.

How did the citizens of Indonesia react to the earthquake in Japan compared to their reactions to earthquakes in Indonesia?

In Japan, despite the large earthquake, many people remained calm, thanks to early warnings via alarms on mobile phones. In Indonesia, however, people panicked even during smaller earthquakes, like the one in Sumedang, West Java, where people were seen evacuating and seeking emergency shelters.

What is the Earthquake Early Warning System (EEWS), and how does it work in Japan?

The Earthquake Early Warning System (EEWS) in Japan alerts citizens about an impending earthquake through alarms on mobile phones, allowing them to take precautionary measures before the earthquake hits, even if they are outside the epicenter.

How does Japan’s earthquake response system compare to Indonesia's efforts?

While Japan has an advanced Earthquake Early Warning System and infrastructure designed to minimize earthquake damage, Indonesia is still in the process of developing and implementing its own EEWS, with ongoing efforts to improve the communication and sensor systems.

What are some key features of Japan's infrastructure that help in mitigating earthquake risks?

Japan's earthquake-resistant infrastructure includes buildings designed to withstand earthquakes, and systems that automatically stop mass transit and gas pipelines to prevent further damage and casualties during an earthquake.

What specific measures does Indonesia need to take to improve earthquake preparedness?

Indonesia needs to strengthen building regulations to ensure earthquake-resistant structures, especially in cities and regions prone to earthquakes. Currently, only about 50 out of 500 Indonesian cities have proper earthquake-resistant building procedures in place.

What role do local governments play in earthquake preparedness in Indonesia?

Local governments in Indonesia play a crucial role in enforcing earthquake-resistant building codes and educating the public on disaster preparedness. However, a significant portion of Indonesian cities still lack these procedures.

How often does Indonesia experience significant earthquakes, and what impact do they have?

Indonesia experiences frequent seismic activity, with about 18,000 earthquakes of magnitude 4 and above, and over 100 earthquakes with magnitude 7 or higher annually. These earthquakes cause damage, especially due to the lack of widespread earthquake-resistant infrastructure.
