How strong was the aftershock that hit Tokyo?

A powerful magnitude 5.9 earthquake shook the Tokyo area of Japan on Thursday night, injuring more than 30 people, damaging underground water pipes and halting trains and undergrounds.

How long did the aftershocks last after the big earthquake?

Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 rupture lengths distance from the mainshock. Aftershocks can continue over a period of weeks, months, or years.

How big can Aftershocks be?

The other, known as Båth's Law, states that the largest aftershock is, on average, about 1.2 magnitudes smaller than the main quake. (The Richter scale is logarithmic, meaning that an earthquake measuring magnitude 6.0 is 10 times larger than one measuring 5.0.)

What is the biggest aftershock ever recorded?

The Largest Aftershock Ever Recorded? The largest aftershock recorded so far of the Mw 9.3 Sumatra earthquake of 26 December 2004 might be assumed to be the 28 March off-Sumatra event (Mw 8.7), which occurred three months later, 160 km away, and with a 0.6 magnitude deficit.

How far inland did 2011 tsunami travel?

Maximum distance inland reached by the tsunami: 6 miles (10 km) in Sendai. Area of land covered by tsunami waters: about 217 sq miles (561 km sq)

Can aftershocks happen 10 years later?

For major quakes that occurred where the sides of a fault moved past each other at average rates of more than 10 millimeters per year — as the two sides of many tectonic boundaries do — aftershocks died off after a decade or so. ... As time passes and the fault recovers, they become increasingly rare.

Can an aftershock be bigger than the earthquake?

Aftershocks are earthquakes that usually occur near the mainshock. The stress on the mainshock's fault changes during the mainshock and most of the aftershocks occur on the same fault. ... Bigger earthquakes have more and larger aftershocks.

Is aftershock stronger than the earthquake?

Aftershocks are sometimes just as hazardous as the main quake itself. In fact, aftershocks may be so strong that they're stronger than the main quake. ... While foreshocks occur around the same time of the main quake, aftershocks may not occur until days or weeks later!

How can an aftershock happen years later?

Effect of aftershocks

Bigger earthquakes have more and larger aftershocks and the sequences can last for years or even longer especially when a large event occurs in a seismically quiet area; see, for example, the New Madrid Seismic Zone, where events still follow Omori's law from the main shocks of 1811–1812.

Is a 6.0 earthquake bad?

The larger the magnitude of the earthquake, the bigger the area over which landslides may occur. In areas underlain by water-saturated sediments, large earthquakes, usually magnitude 6.0 or greater, may cause liquefaction. The shaking causes the wet sediment to become quicksand and flow.

What is a phantom quake?

Real aftershocks are possible after big earthquakes — but imagined ones can happen, too. ... “Aside from aftershocks, anyone caught up in the disaster may also experience the uncanny sensation of 'phantom quakes,' where it feels as if the earth is shaking when, in fact, it is perfectly still,” Glaser wrote.

Do all earthquakes have foreshocks?

This means that there is about a 94% chance that any earthquake will NOT be a foreshock. In California, about half of the biggest earthquakes were preceded by foreshocks; the other half were not.

Is a 10.0 earthquake possible?

No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. ... The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.

What would a 10.0 earthquake do?

A magnitude 10 quake would likely cause ground motions for up to an hour, with tsunami hitting while the shaking was still going on, according to the research. Tsunami would continue for several days, causing damage to several Pacific Rim nations.

Has there ever been a 9 earthquake?

The world's first recorded magnitude 9.0 earthquake struck off the east coast of Kamchatka in 1952. The quake generated a 43-foot tsunami (13 m) locally. The tsunami rocked Crescent City, Calif., which was also hit hard by the recent Japan earthquake.
