Earthquake Summary

The earthquake struck on land in Indonesia, 173 kilometer (107 mi) west-southwest of Jayapura in Papua. The center of this earthquake had a quite shallow depth of 38 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 1.6 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 1.6 million have been exposed to shaking at an MMI level of II or higher.

Moderate shaking and very light damage may have been experienced by an estimated 6,150 people. At V, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 1.4 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. Roughly 1.6 million people were exposed to shaking in Indonesia , with level V (moderate shaking, very light damage) as the highest recorded. Shaking was experienced by inhabitants of Papua New Guinea too.

People	MMI Level	Shaking	Damage
0	I	Not noticable	None
64,970	II	Very weak	None
1,416,000	III	Weak	Probably none
100,900	IV	Light	Likely none
6,150	V	Moderate	Very light
0	VI	Strong	Light
0	VII	Very Strong	Moderate
0	VIII	Severe	Moderate to heavy
0	IX	Violent	Heavy
0	X	Extreme	Very heavy

Nearby towns and cities

This earthquake may have been felt in Indonesia . The closest significant population center near the earthquake is Abepura in Papua, Indonesia. Abepura is located 162 kilometer (101 mi) west-southwest of the epicenter. The intensity of shaking and damage in Abepura is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

Aftershocks detected

This main shock was prefaced by 2 smaller foreshocks. A 4.6 magnitude earthquake hit 3 days earlier nearby.

Overview of foreshocks and aftershocks

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.
Classification	Magnitude	When	Where
Foreshock	M 4.6	3 days earlier Jun 6, 2024 22:33 (Jayapura Time)	99 km (61 mi) W from Main Shock.
Foreshock	M 4.3	2 days earlier Jun 7, 2024 20:38 (Jayapura Time)	42 km (26 mi) NW from Main Shock.
Main Shock	M 4.6	Jun 9, 2024 20:16 (Jayapura Time)	-

More earthquakes coming?

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.

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. This is the strongest earthquake to hit since May 21st, 2024, when a 5.3 magnitude earthquake hit 144 km (89 mi) further northwest. An even stronger magnitude 7 earthquake struck on July 27th, 2015.

In total, 57 earthquakes with a magnitude of 5.3 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	Not this earthquake. This earthquake appears to have struck on land far from any coast.	Not this earthquake. This earthquake had a magnitude of 5.3. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 38 km (24 mi). Earthquakes this shallow could trigger a tsunami.
