Significant impact predicted
The US Geographic Survey (USGS) describes the impact of this earthquake as follows:
At least 24 people injured and 213 buildings damaged in the Dezhou-Liaocheng area.
Based on scientific estimates by the USGS, the risk of high fatalities for this earthquake is classified at level YELLOW (significant). They expect an 38% likelyhood of between 1 and 10 fatalities, and a 99% chance that the number of fatalities falls no higher than 1,000.
The USGS classifies the economic impact of this earthquake at level RED (high). They expect an 35% likelyhood of between 1,000 and 10,000 million US Dollars in economic damage and impact, and a 91% chance that the economic impact of this earthquake falls between 10 and 100,000 million USD.
Roughly 109 million people exposed to shaking
An estimated 109 million have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.
The highest earthquake impact level for this earthquake is VII, which corresponds with very strong shaking and likely moderate damage. Roughly 132,100 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 73 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of China .

Nearby towns and cities
This earthquake may have been felt in China . Located 24 kilometer (15 mi) south of the epicenter of this earthquake, Dezhou (Shandong, China) is the nearest significant population center. The intensity of shaking and damage in Dezhou is estimated to be around level V on the Modified Mercalli Intensity scale (moderate shaking, very light damage).
Multiple large cities are in proximity of today's earthquake. Beijing is located 298 km to the north (intensity unknown, possibly low). Jinan is located 83 km to the south-east and experienced an intensity of IV (light shaking, likely no damage). Tianjin is located 223 km to the north-northeast (intensity unknown, possibly low).

Risk of aftershocks?
We monitor for foreshocks or aftershocks that have a magnitude of 2.5+ and occur within 100km (62 mi) of the epicenter of this earthquake. So far no such earthquakes have been detected.
Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.
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.

No earthquake of this strength has struck this region for a long time. Our data goes back 10 years, and no earthquakes measuring a magnitude of 5.4 or higher have been detected within 300 km (186 mi) of this epicenter.
Tsunami very unlikely
While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.
Tsunami Risk Factors
Factor | Under Sea? | MAG-6.5 or stronger? | Shallow depth? |
---|---|---|---|
Explanation | Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. | Under MAG 6.5: Very unlikely to cause a tsunami. MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes. MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's. |
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor. |
This Earthquake | Not this earthquake. This earthquake appears to have struck on land far from any coast. |
Not this earthquake. This earthquake had a magnitude of 5.4. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 18 km (11 mi). Earthquakes this shallow could trigger a tsunami. |
