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 76% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 98% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 24 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 24 million have been exposed to shaking at an MMI level of II or higher.

An estimated 124,700 people were exposed to level VII. At this level, very strong shaking and likely moderate damage can be expected. Intensity level III was experienced by the majority of people (around 17 million). In their region, weak shaking and probably no damage can be expected.

People in 3 countries have been exposed to shaking. In Taiwan , around 23 million people, with impact levels up to VII (very strong shaking, likely moderate damage). A smaller number of people were exposed in the following countries: China and Japan.

The intensity of shaking and damage in Hualien City is estimated to be around level VII on the Modified Mercalli Intensity scale (very strong shaking, likely moderate damage).

Multiple large cities are in proximity of today's earthquake. Hualien City is located 2 km to the north-northeast and experienced an intensity of VII (very strong shaking, likely moderate damage). Taipei is located 121 km to the north and experienced an intensity of IV (light shaking, likely no damage). Taichung is located 95 km to the west-northwest and experienced an intensity of IV (light shaking, likely 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.

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.

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.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 55 earthquakes with a magnitude of 5.5 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 2 months.

Tsunami very unlikely

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

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 This earthquake appears to have struck on land near a coastal area (1 km from the sea). Not this earthquake.
This earthquake had a magnitude of 5.5. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 10 km (6 mi). Earthquakes this shallow could trigger a tsunami.
