Earthquake back hit Fukushima prefecture in northern Japan, a magnitude 7.3 on the Richter scale, Monday, November 21, 2016, at 05:59 local time.
Because of the magnitude of shocks, vibrations felt in Tokyo, capital of Japan, which is 239 kilometers. Almost equal to the distance from Jakarta to Brebes, Central Java.
As quoted from the RT , the Japan Meteorological Agency, the country’s meteorological agency reported, three hours after the earthquake struck, 1.4-meter-high tsunami was reportedly spotted in Sendai, Miyagi Prefecture.
In addition, the Port of Soma with a height of 90 centimeters, and in Ishinomaki Ayukawa and Port Kuji which reached 80 centimeters. The tsunami created by not creating a serious impact, since the waves coming from the sea water was not until the flooded area residents.
This incident recalled by the earthquake that hit the region on 11 March 2011. At that time, an earthquake struck the strength of 9.0 on the Richter scale. Creating a 10 meter tsunami wave.
Impact, Japanese National Police Agency confirmed the 15 269 killed, 5,363 wounded, and 8,526 missing in six prefectures, earthquake emergency kit
The most terrible is the destruction of the cooling system at the Fukushima Nuclear Power Plant, thus creating radiation that contaminates the sea, land, and air. The government also issued a state of emergency, and hundreds of thousands of residents had to be evacuated.
Anticipating the event, power plants and nuclear reactors that are directly off the coast, to minimize the spread of radiation into the air and water.
Tokyo Electric Power as the company that operates the nuclear plant said there has been no significant damage at the power plant caused by the earthquake. However, for the time being, the affected area has not been able to use electric energy.
The company also announced the condition of the reactor at the Fukushima nuclear power plant in a safe condition. Reactor cooling system which had been halted because of the earthquake, could certainly operate.
The fate of the Indonesian citizens
Deputy Ambassador of the Republic of Indonesia in Tokyo, Japan, Ricky Suhendar, ensuring 3,700 Indonesian citizens living in the four affected areas, is safe.
“There are four areas hit by the earthquake and tsunami. That Miyagi Prefecture, Fukushima Prefecture, Aomori Prefecture, and Chiba Prefecture. All the citizens who live there certainly safely and no one was hurt,” said Ricky, when talking with Reuters on Tuesday, 22 November 2016.
Despite all the citizen survived Embassy in Tokyo remained wary of aftershocks. Therefore, Japan was known to often hit by earthquakes. The country has a seismically active area because of the subduction zone or earth plate collision.
According to the Head of the Earthquake and Tsunami Meteorology, Climatology, and Geophysics, Mochammad Riyadi, with strong shocks, it is estimated the impact of the earthquake can cause damage to building a moderate level.
“The earthquake-Koriyama Fukushima is happening now is a kind of shallow earthquakes in subduction zones. In this case, the Pacific Plate subduction zone slipped under the Okhotsk Plate,” Riyadi said through a press release received VIVA.co.id Tuesday, 22 November 2016.
Riyadi explained, the Pacific Tsunami Warning Center based in Hawaii reported that the earthquake has triggered a local tsunami around the epicenter.
“Based on the analysis and modeling of tsunami conducted by the BMKG, indicating that the tsunami would not affect in the region of Indonesia,” said Riyadi.
To that end, BMKG warned residents living on the coast of the Pacific Ocean, to remain calm and ignore the issue.
Similar in Indonesia
The frequency of earthquakes in ‘country of Sakura’ is actually also a challenge in Indonesia. Equally as an archipelagic country, Indonesia also has many subduction zones, so that the potential occurrence of earthquakes is also often hit.
The difference is, when the big earthquake in Japan, the number of casualties can be minimized. Meanwhile, for Indonesia, the death toll is often comparable to the strength of the earthquake. If a large number of people confirmed much.
If you look at the historical record, since an earthquake rocked Aceh with power from 9.1 to 9.3 on the Richter scale on December 26, 2004, every year there are a large magnitude earthquake in Indonesia.
After Aceh, March 28, 2005, an earthquake occurred in Nias measuring 8.7 on the Richter scale.
Then, on May 27, 2006, rocked Yogyakarta turn shallow earthquakes measuring 5.9 on the Richter scale.
Then, on 12 September 2007, an earthquake measuring 7.9 on the Richter scale hit the west coast of Padang and Bengkulu. This event is also known as the Nias earthquake.
The earthquake then occurred on November 16, 2008 in the north coast of Sulawesi, measuring 7.5 on the Richter scale. Then, the 7.3-magnitude earthquake in Tasikmalaya on 2 September, 2009.
In 2010, precisely October 25, a magnitude 7.7 on the Richter scale occurred in the Mentawai Islands. Then, in subsequent years earthquakes continue to occur with increasing frequency.
According to experts, geophysics and volcano, Surono, Indonesia since the first is a subscription earthquake. It is also evident from the culture and architectural style of the local community, which generally use the stage house.
“It was a house that is resistant to earthquakes, because the pillars into a single unit,” said Surono when contacted VIVA.co.id, Tuesday, November 22, 2016.
So, if you want to learn about disaster mitigation, said Surono, Indonesia stayed learn from history and ancestral culture. No need to look far to Japan, because there is no other country that has experience of dealing with the disaster.
“I am more daring study with Indonesia. Indonesia disaster mitigation since the ancestors already there,” he said.
The problem is, the ancestors never write about the experience of their history to natural disasters. They were handed down through the arts, good songs, fairy tales, folklore and more.
Surono reveals the weakness of disaster mitigation programs in Indonesia, bringing the total number of victims is difficult minimized. Meanwhile, Japan, is very successful. “The Japanese people want to be trained, the key there,” he said.
When I was the head of the Geological Agency, Surono never made a Hazard Mitigation Program Without Ties and bread. The program is organized around 2007 to communities around Mount Merapi, as a precaution due to the potential of the mountain will erupt.
Surono meaning without a tie is present in front of the public to leave the formalities as a state official. Meanwhile, without bread, they supplied food usually eaten residents.
This situation was created to create a comfortable atmosphere and eliminate formal barriers, which she values would hamper counseling.
“Eat what’s in there, is not bread, and I do not need to wear a tie. There are more effective because they know I am not a lecture. I’m trying to straighten out of the question, sit not wear seat, sitting on the floor, eating what it is, it is taxable , “he said.
As natural disasters, earthquakes can not be predicted arrival. Humans also do not have the technology to prevent it from happening, so the best chance of disaster risk reduction is to the success of the mitigation program.
“The problem can not be earthquake engineering ( design), I have to engineer is its people,” said Surono.
There, he saw a difference between the people of Indonesia and Japan. That attitude has resulted in a significant difference for extended survival time of a natural disaster.
Surono said, advances in technology have no meaning, if people do not have an awareness of disaster mitigation. He pointed out, one of the successes of disaster mitigation programs in Indonesia, is when Merapi erupted.
Due to the alertness of apparatus plus mitigation programs that run widely, from about one million people living at the foot of the mountain, the death toll at around 350 people.
At that time, people are willing to be evacuated because they understand the dangers of disasters.
On the other hand, Sri Sultan Hamengkubuwono X as governor of Yogyakarta, also fully supports the government’s move. This combination creates a good climate for disaster mitigation.
“Death is God disposes, but do not give up. That ultimately is the destiny of the disaster, but we as human beings have reason and mind, so that we can be engineered, peace with nature,” said Surono.
