First and foremost, my family and everyone who I know are fortunately safe from any harm. But this coming days/weeks will be somewhat worrying, as there is a high chance of a further aftershock of M6+ happening within the next couple of weeks.
But this is the warning alert that came through on my phone last night.
The earthquake was felt across the majority of Japan... From the northern island of Hokkaido, all the way as far south/west as Hiroshima! With the hardest hit area being the Tohoku region, that experienced an Upper 6 on the Shindo Scale!
Meanwhile, in Tokyo, we experienced the quake as a 4 on the Shindo Scale. Which is still powerful enough to make your house/apartment shake and frighten young children/those aren't used to major earthquakes.
For those who are unaware of the Shindo Scale. It's a series of measurements that measure the intensity of the shake in different affected areas.
And to give it some perspective... The M9.0 earthquake that devastated Japan in 2011, was a 7 on the Shindo Scale. That should give some perspective to just how powerful this recent earthquake was.
And as the clean up from this latest earthquake continues. Everyone is mindful of the fact that strong aftershocks could most likely occur in the coming weeks. But for now, I think that we're all just thankful that unlike 10 years ago. A tsunami didn't follow this time, and the number of confirmed casualties is low (for now)
And as for more information on the earthquake itself... Experts are saying that last night's M7.3 earthquake that rocked the country, was an aftershock from the 2011 M9.0 quake that devastated the Tohoku region almost 10 years ago.
"Saturday’s magnitude 7.3 quake that struck off the Tohoku coast is believed to be an aftershock of the 2011 killer earthquake that triggered a massive tsunami in the area, a seismologist said.
“Because (the 2011 quake) was an enormous one with a magnitude of 9.0, it’s not surprising to have an aftershock of this scale 10 years later,” said Kenji Satake, a professor at the University of Tokyo’s Earthquake Research Institute.
Despite the relatively large size of the latest quake with the focus off Fukushima Prefecture, it was unlikely to have caused a tsunami because it had a deep epicenter of about 55 kilometers below the sea surface, Satake said.
The Meteorological Agency also said it believed the 11:07 p.m. quake was an aftershock of the megaquake that struck the area nearly 10 years ago to the date.
According to the agency, the quake’s seismic intensity — a strong 6 on the Japanese scale of 7 — was the strongest to occur off the country’s northeastern coast since April 7, 2011.
On March 11 that year, the magnitude 9.0 quake rocked the region, registering a 7 on the Japanese scale and triggering a massive tsunami. The disasters subsequently spurred the triple-meltdown at the Fukushima No. 1 nuclear power plant.
A quake with intensity of an strong 6 and 7 is defined by the agency as making it “impossible (for humans) to remain standing or move without crawling” and people may even be “thrown through the air.”
The difference between upper 6 and 7 is their impact on furniture, walls and windows. In the former, “most unreinforced concrete-block walls collapse,” but even “reinforced concrete-block walls may collapse” in the latter, the agency says."
