Earthquake Summary

This earthquake hit under water in the North Pacific Ocean, 162 kilometers (100 mi) off the coast of Japan, 270 kilometer east-northeast of Sendai in Miyagi. The center of this earthquake had a very shallow depth of 10 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 0.9 million people exposed to shaking

This earthquake may have been felt by around 0.9 million people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

An estimated 39,040 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. Intensity level III was experienced by the majority of people (around 0.9 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 . Yamada in Iwate, Japan is the nearest significant place from the epicenter. The earthquake occurred 135 kilometer (84 mi) east of Yamada. The intensity of shaking and damage in Yamada is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Multiple major population centers exist within 300km of the earthquake that struck today. Sendai is located 270 km to the west-southwest (intensity unknown, possibly low). Morioka is located 204 km to the west (intensity unknown, possibly low). Hachinohe is located 203 km to the west-northwest and experienced an intensity of III (weak shaking, probably no damage).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

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

Approximately 23 hrs before this earthquake hit, a larger 6.8 magnitude earthquake struck 14 km (9 mi) west-southwest of this one. For that reason, we classify the Mag. 6.0 earthquake as an aftershock.

Overview of foreshocks and aftershocks

More earthquakes coming?

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 21 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.
