At that time, the scale had four levels: bishin (微震, faint tremor), jakushin (弱震, weak tremor), kyōshin (強震, strong tremor), and retsushin (烈震, violent tremor). For example, a faint tremor event was described with a brief explanation, such as "Slightly felt by those who have experience of earthquakes" [ 13 ] [ 14 ] [ 15 ] .
In the late infantile form, which is the most common form of MLD (50–60%), affected children begin having difficulty walking after the first year of life, usually at 15–24 months. Symptoms include muscle wasting and weakness, muscle rigidity , developmental delays, progressive loss of vision leading to blindness, convulsions , impaired ...
It measured M w 6.8 on the Moment magnitude scale , [57] and Mj7.3 on the revised (7.2 on the old) JMA magnitude scale. [58] The tremors lasted for approximately 20 seconds. The hypocenter of the earthquake was located 16 km (9.9 mi) beneath its epicenter, [58] on the northern end of Awaji Island, 20 km (12 mi) away from the city of Kobe.
The tremor measured 7.7 on the moment magnitude scale and 7.3 on the Richter scale, [9] and the focal depth was 8.0 km (5.0 mi). The Central Weather Bureau recorded a total of 12,911 aftershocks in the month following the mainshock. [10] The total energy released is estimated to be 2.1 × 10 17 J, [11] approximately the same as the yield of the ...
An earthquake – also called a quake, tremor, or temblor – is the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity , from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage ...
Largest in a swarm of 219 tremors affecting the area in one day. [34] Four people injured, [35] 713 houses destroyed and 415 others damaged in El Salvador. [36] At least 55 houses destroyed and 161 others damaged in Guatemala. [37] - 4 16 [38] Japan, Bonin Islands offshore 6.3 405.0 III - - - 17 [39] Iran, Mazandaran, 14 km (8.7 mi) south of ...
Since then, measurements from satellites have shown that mountain parts directly above the epicenter have risen by a few meters, giving ample proof that the Himalayas are still being formed and growing and that this earthquake was a consequence of that. [28] By the end of 2005, a total of 1,778 aftershocks were recorded. [29]
The governor of Ishikawa Prefecture, Hiroshi Hase, said that the earthquake had produced at least 2.4 million tons of waste, equivalent to seven-years' worth of waste produced in the prefecture, with 60 percent of it originating in Suzu, Wajima, Noto and Anamizu, which was also equivalent to 60 years' worth of waste produced in these towns.
