Jakarta – Lembang fault is an active earth error that keeps moving. The National Research and Innovation Agency (Brin) revealed that the paleoseismology record showed that a large earthquake took place hundreds of years ago and that the cycle could be repeated. The following is the everyday information about the Lembang error. Browse to continue with the content What is the Lembang error? Based on official information from Brin, the Lembang error in North Bandung extends nearly 29 kilometers from Padalarang to Cimenyan, at the foot of Mount Tangkuban Parahu. This road is not just a line on the map, but an active error. Mount Batu, who is at miles 17, is clear evidence of the activities of the Lembang error. During the earthquake, this hill can rise to 40 cm. It shows that this error is still active. The study showed that the Lembang error moves 1.9 – 3.4 millimeters per year. This rate looks small, but in a period of hundreds of years can cause a great earthquake. Traces and estimated earthquakes Paleoseismology studies found that large earthquakes occurred in the Lembang error in the 15th century, about 60 years before AD and approximately 19,000 years ago. With a cycle of 170-670 years, the next major earthquake does not take place later than 2170. That is, this duration is relatively close to our time. Lembang fault is an active error system to be monitored. Although Earth Science cannot be sure when a great earthquake occurs, the awareness and preparedness of the community is the most important to reduce ram risk. Types of earthquake size According to the Indonesian page, size is a measure of earthquake that describes the amount of seismic energy released by the source of the earthquake and the result is of seismographic observations. BMKG Indonesia uses a size scale (M) as a measure of earthquake strength. In the past, the size of the earthquake that was often used by BMKG was the Richter (SRC) scale. But now BMKG uses a large scale because it is considered more accurate. Meanwhile, the amended Mercalli intensity (MMI) scale is frequently used to measure the shocks felt by residents during the earthquake. This unit was created in 1902 by a volcanology from Italy named Giuseppe Mercalli. The following types of earthquake size and their understanding. Size 2.5 or less: usually not felt, but can be recorded with seismograph. Size 2.5 – 5.4: often feels, but only causes small damage. serious. Size 8.0 or larger: Great earthquake. Can destroy the community near the earthquake. (KNY/IMK)
