According to the latest statistics released today by the spokesperson of the National Disaster Resistance Agency of Indonesia, the earthquake and tsunami triggered by Central Sulawesi Province on September 28 have killed at least 1,234 people and 99 people have disappeared.
After the strong earthquake and tsunami, the city was devastated
Some media released a set of satellite pictures taken by Palu in the severely affected area before and after the tsunami. You can clearly feel the heavy damage caused by the earthquake and tsunami and tsunami to the city.
This set of satellite images was taken on August 17 and October 1 respectively.
This is a bridge in Palu. After the tsunami, the bridge deformed, the sea water became turbid, and surrounding buildings were significantly damaged. ↓
At a pier in Palu, none of the building facilities on the water and on the shore were spared, and the damage was severely damaged. ↓
This is a shopping center near the sea, and many buildings have become ruins. ↓
And in some residential areas, after the earthquake, a large area has been razed to the ground, leaving only waste rocks and rubble. ↓
Multiple forces are working hard to search and rescue
The Indonesian earthquake and tsunami have suffered serious losses of personnel and property, and nearly 50,000 people have been forced to be transferred. The area with the most casualties is Palu City. There are many hotels, shopping malls and other densely populated buildings that collapsed due to earthquakes, which is also a key area for search and rescue.
htmlOn the 1st, rescuers spent three hours to rescue a 38-year-old man from a financial building in Palu City. Another hotel, which originally had a seven-story building, collapsed in the earthquake, and about 50 people were still trapped under the ruins. Rescuers were working hard to search and rescue here on the 2nd, and they expressed their belief that there are still survivors under the ruins. Rescue personnel also sent search and rescue dogs to participate in the rescue and search for survivors.
Due to earthquakes and tsunamis, traffic is blocked, power and communications are not smooth, and rescue work is also facing great difficulties. At present, the disaster situation in many areas such as Donggara and Sigi needs further assessment, and rescue workers are still working hard to penetrate more disaster areas. On the 2nd, the Indonesian military sent military transport planes to transfer some of the victims of Palu to East Java .
Local officials: The supply in the disaster area is recovering
Indonesian Central Sulawesi Province officials said in an interview with CCTV reporters that the supply in the disaster area is recovering, and there are still 48,000 victims in the disaster area that need assistance. Rescue materials are being shipped to the disaster area one after another, and electricity supply is expected to fully recover within two weeks. Faced with the fuel shortage, the government is mobilizing its full strength. At present, the airport is still closed and the airport will resume operations after the damaged runway is completely repaired.
Warning failure terrain may cause heavy casualties
Indonesia is located in the Pacific Rim seismic zone and is frequently hit by earthquakes, volcanic eruptions and tsunamis. Regarding the reasons for the catastrophic consequences and heavy casualties, experts believe that is mainly related to the failure of the tsunami warning system and the special terrain of the affected cities.
Indonesia has deployed a tsunami monitoring and early warning network composed of 22 floats . These buoys are connected to subsea sensors to monitor slight pressure changes, thus issuing a tsunami warning. But the Indonesian National Disaster Resistance Agency said that the buoys were damaged and "none of them is operating."
At present, Indonesia's tsunami warning system mainly relies on seismometer and tide level meter. Indonesian Meteorological, Climate and Geophysics Agency released the alarm 34 minutes after the earthquake, based on the tide level gauge records. Without the alarm, many people are not aware of the threat. In the worst-hit city of Palu, people were attending festivals on the beach when the tsunami hit, which was one of the reasons for the serious casualties of the tsunami.
Palu terrain is like a trumpet, amplifying the power of the tsunami
Some experts believe that another important reason for the heavy casualties of this tsunami is that the geographical location and special terrain of Palu City have encouraged the "lethality" of the tsunami.Palu is located at the estuary, high on both sides and low on the middle, like a trumpet, which has a significant amplification effect on the tsunami, resulting in unexpected and disastrous results.
Experts speculate that the undersea landslide caused a huge tsunami
In addition, the reason for the tsunami also puzzled scientists. The main earthquake of this earthquake, , is a strike-slip earthquake, and generally, earthquakes like this will not cause a huge catastrophic tsunami. However, the tsunami caused by the earthquake caused a wave of up to 6 meters in the waters near Palu. Some earthquake scholars speculated that the main earthquake caused a secondary disaster of a submarine landslide, and it was this sudden underwater movement that triggered a huge tsunami. But this conjecture needs further verification.
