Earthquake Summary

This earthquake hit under water in the North Pacific Ocean, 142 kilometers (88 mi) off the coast of Japan, 189 kilometer east of Morioka in Iwate. The center of this earthquake had a very shallow depth of 11 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 fatalities, and a 96% chance that the number of fatalities falls no higher than 10.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 96% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 2 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 2 million have been exposed to shaking at an MMI level of II or higher.

Light shaking and likely no damage may have been experienced by an estimated 17,530 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 1.9 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Japan .

Nearby towns and cities

This earthquake may have been felt in Japan . Located 120 kilometer (75 mi) east of the epicenter of this earthquake, Yamada (Iwate, Japan) is the nearest significant population center. Yamada experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Major cities near this earthquake: Sendai is located 257 km to the southwest (intensity unknown, possibly low). Morioka is located 189 km to the west and experienced an intensity of III (weak shaking, probably no damage). Hachinohe is located 190 km to the northwest and experienced an intensity of III (weak shaking, probably no damage).

The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

Shaking reported by 5 people

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 5 people have reported shaking in 3 places, all within Japan.We keep updating this article as more ground reports become available. You may report that you felt this earthquake here.

Places with most reports:

• Sendai, Miyagi, Japan: 3 people.
• Hakodate, Hokkaido, Japan: 1 person.
• Niigata, Niigata, Japan: 1 person.

This is likely an aftershock

This earthquake was an aftershock. A larger mag. 6.8 earthquake struck 17 km (11 mi) south-southeast in advance of this 6.0 earthquake around 23 hrs earlier.

Overview of foreshocks and aftershocks

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 22 earthquakes with a magnitude of 6 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 6 months.

Low tsunami risk

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so stay cautious and monitor advice from local authorities.
