The magnitude of an earthquake is a measured value of the earthquake size. Most earthquakes occur at depths of less than 80 km (50 miles) from the Earth’s surface. The first “pendulum seismoscope” to measure the shaking of the ground during an earthquake was developed in 1751, and it wasn’t until 1855 that faults were recognized as the source of earthquakes. There is a medium-sized one three stories high in Mexico City that is still in operation. In 1976 another deadly earthquake struck in Tangshan, China, where more than 250,000 people were killed.īefore electronics allowed recordings of large earthquakes, scientists built large spring-pendulum seismometers in an attempt to record the long-period motion produced by such quakes. These dwellings collapsed during the earthquake, killing an estimated 830,000 people. It struck a region where most people lived in caves carved from soft rock. The world’s deadliest recorded earthquake occurred in 1556 in central China. The largest recorded earthquake in the world was a magnitude 9.5 (Mw) in Chile on May 22, 1960. 100,000 of those can be felt, and 100 of them cause damage. It is estimated that there are 500,000 detectable earthquakes in the world each year. Contoh Report Text Tentang Bencana Alam Gempa Bumi.In July 2013, TEPCO, the Tokyo Electric Power Company, admitted that about 300 tons of radioactive water continues to leak from the plant every day into the Pacific Ocean. The electrical power and backup generators were overwhelmed by the tsunami, and the plant lost its cooling capabilities. The tsunami caused a cooling system failure at the Fukushima Daiichi Nuclear Power Plant, which resulted in a level-7 nuclear meltdown and release of radioactive materials. The tsunami flooded an estimated area of approximately 217 square miles (561 square kilometers) in Japan. The tsunami waves reached run-up heights (how far the wave surges inland above sea level) of up to 128 feet (39 meters) at Miyako city and traveled inland as far as 6 miles (10 km) in Sendai. Less than an hour after the earthquake, the first of many tsunami waves hit Japan's coastline.
People in Japan also received texted alerts of the earthquake and tsunami warnings on their cellphones. The country's stringent seismic building codes and early warning system prevented many deaths from the earthquake, by stopping high-speed trains and factory assembly lines. Residents of Tokyo received a minute of warning before the strong shaking hit the city, thanks to Japan's earthquake early warning system. The earthquake was centered on the seafloor 45 miles (72 kilometers) east of Tohoku, at a depth of 15 miles (24 km) below the surface. On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami. Contoh Report Text Tentang Bencana Alam Tsunami Di Jepang.
