Seismic activity in Chile on May 6 drew attention through various monitoring reports, focusing on recent temblors, their epicenters, and magnitudes.[1] This overview captures the situation as presented in initial coverage, which highlighted multiple earthquakes occurring in the country on that specific date.[1] The reports served as a call to review the locations and strengths of these events, providing a snapshot of the day's seismic occurrences.[1]
The context of these events underscores a cluster of activity noted in Chile, with sources emphasizing the need to examine epicenters precisely and magnitudes accurately.[1] Published updates from that day, timestamped around mid-afternoon UTC, compiled information on the latest sismos, positioning these earthquakes within the broader pattern of tremors reported.[1] This summary aligns with the general reporting purpose, introducing the key incidents without delving into isolated details yet.[1]
Further examination of the day's reports reveals a focus on transparency regarding locations west and southeast of major population centers in Chile.[1] The temblor coverage on May 6 encouraged public and official review of data, ensuring that epicenter coordinates and magnitude assessments were readily accessible.[1] Such overviews play a critical role in situating individual quakes within the day's overall seismic profile in Chile.[1]
Reports like the one from gdelt provided a foundational layer for understanding the scope, repeatedly stressing "temblor hoy 6 de mayo en Chile" to signal immediate relevance.[1] This phrasing encapsulated the urgency of checking recent seismic data, setting the stage for detailed breakdowns of specific events.[1] By compiling epicenter, magnitude, and last sismos information, the overview facilitated a comprehensive initial assessment.[1]
In essence, the seismic events of May 6 in Chile were framed as warranting close inspection, with sources prioritizing factual dissemination of locations and intensities.[1] This introductory perspective ensures readers grasp the multiplicity of tremors before exploring individual cases.[1]
Details of the Primary Earthquake
The primary earthquake, reported by the USGS, registered a magnitude of 4.7 and was located 90 km west-southwest of Coquimbo, Chile.[2] This event occurred at a depth of 10.0 km, marking it as a shallow seismic occurrence relative to others in the vicinity.[2] The precise designation "M4.7 Earthquake - 90 km WSW of Coquimbo, Chile" captures the USGS's direct reporting on this significant tremor.[2]
Detailed analysis of this quake's parameters reveals its epicenter positioned offshore, 90 kilometers in the west-southwest direction from Coquimbo.[2] The shallow depth of 10.0 km positions it among events capable of stronger surface effects, though specifics on impacts remain tied to the reported metrics.[2] USGS documentation consistently lists the magnitude as 4.7, emphasizing its status as the strongest in the immediate Coquimbo-area cluster on May 6.[2]
This earthquake's location, 90 km WSW, places it in a marine area off Chile's coast, with Coquimbo serving as the key reference point.[2] The depth measurement of exactly 10.0 km underscores the event's proximity to the surface, a detail reiterated in the source material.[2] Such precision in reporting aids in modeling potential propagation, though the focus here stays on the confirmed facts.[2]
The USGS entry for this M4.7 event integrates location, magnitude, and depth seamlessly, offering a standalone profile of the quake.[2] West-southwest orientation from Coquimbo highlights directional accuracy, essential for mapping seismic patterns.[2] On May 6, this stood out as the lead event in reports, given its magnitude.[2]
Rephrasing the core details, the earthquake measured 4.7 in magnitude, epicentered 90 km WSW of Coquimbo at 10.0 km deep.[2] This configuration aligns with standard USGS formatting for offshore Chilean tremors.[2] The event's documentation ensures traceability for all claims related to its specifics.[2]

Additional Earthquakes in the Region
Beyond the primary event, additional earthquakes enriched the regional seismic picture on May 6, with USGS reports detailing a magnitude 4.3 quake 11 km southeast of Camiña, Chile, at a depth of 115.5 km.[3] Another significant tremor, a magnitude 4.6 earthquake 74 km west-southwest of Coquimbo, Chile, also at 10.0 km depth, complemented the activity.[4]
The M4.3 event near Camiña, specified as "11 km SE of Camiña, Chile," represents an inland occurrence distinct from coastal quakes.[3] Its greater depth of 115.5 km contrasts sharply with shallower events, providing context for varied tectonic expressions in Chile.[3] USGS confirmation of magnitude 4.3 ties it directly to the day's reports.[3]
Similarly, the M4.6 earthquake, located 74 km WSW of Coquimbo—closer to shore than the 4.7—mirrors the primary event's depth at 10.0 km.[4] This proximity in location and depth suggests clustered activity west-southwest of Coquimbo.[4] The USGS labeled it "M4.6 Earthquake - 74 km WSW of Coquimbo, Chile," affirming its role.[4]
These additional quakes, occurring around the same timeframe, expand the narrative of May 6 seismic events.[3][4] The Camiña-area tremor at 11 km SE introduces a southeastern inland element, while the 74 km WSW event reinforces offshore patterns near Coquimbo.[3][4] Together, they illustrate multifaceted regional activity.[3][4]
Cross-referencing shows the 4.6 magnitude event sharing directional and depth traits with the 4.7, both WSW of Coquimbo at 10.0 km.[2][4] Meanwhile, the 4.3's 115.5 km depth and SE Camiña location diversifies the profile.[3] Such details from USGS sources ground the additional context.[3][4]
Locations and Depths of Events
Geographical and depth specifics paint a complete picture of the May 6 earthquakes, starting with the M4.7 at 90 km WSW of Coquimbo, Chile, depth 10.0 km.[2] The M4.6 event at 74 km WSW of the same city shared the 10.0 km depth, indicating similar shallow origins.[4] Farther, the M4.3 struck 11 km SE of Camiña, Chile, at 115.5 km deep.[3]
Coquimbo emerges as a pivotal reference for two events: 90 km and 74 km WSW, both at uniform 10.0 km depths.[2][4] This clustering underscores localized offshore positioning west-southwest of the coastal city.[2][4] Depths of 10.0 km for both suggest comparable rupture conditions.[2][4]
In contrast, the Camiña event's location 11 km southeast places it inland, with a substantially deeper 115.5 km measurement.[3] This depth variation highlights diverse subduction dynamics potentially at play in Chilean seismicity.[3] USGS precision in "11 km SE of Camiña, Chile" ensures locational clarity.[3]
Summarizing positions: WSW from Coquimbo for the 4.7 and 4.6 quakes at shallow 10.0 km, versus SE from Camiña for the 4.3 at 115.5 km.[2][3][4] These metrics form the backbone of event profiling.[2][3][4] Directional terms like WSW and SE provide navigational context from named locales.[2][3][4]
The shallow Coquimbo-area depths (10.0 km) versus the deeper Camiña event (115.5 km) offer comparative insight grounded in reports.[2][3][4] Locations—90 km, 74 km WSW Coquimbo; 11 km SE Camiña—enable spatial mapping.[2][3][4]

Summary of Reported Activity
Recapping the key seismic events from May 6 in Chile, reports encompassed a magnitude 4.7 earthquake 90 km WSW of Coquimbo at 10.0 km depth.[1][2] A magnitude 4.6 event 74 km WSW of Coquimbo, also at 10.0 km, and a magnitude 4.3 quake 11 km SE of Camiña at 115.5 km rounded out the documented tremors.[1][3][4]
General coverage via gdelt emphasized reviewing epicenters, magnitudes, and latest sismos for the day.[1] USGS details filled in the specifics: M4.7 (90 km WSW Coquimbo, 10.0 km), M4.6 (74 km WSW Coquimbo, 10.0 km), M4.3 (11 km SE Camiña, 115.5 km).[2][3][4] This synthesis closes the report on verified activity.[1][2][3][4]
The cluster near Coquimbo—two shallow quakes at 10.0 km—contrasts with the deeper Camiña event, all under May 6 scrutiny.[1][2][3][4] Sources collectively affirm these as the highlighted incidents.[1][2][3][4]
What to Watch Next
Ongoing reviews of epicenters, magnitudes, and latest sismos in Chile, as indicated in May 6 reports, suggest continued monitoring for subsequent seismic events.[1] Updates from USGS on similar regional quakes may provide further context to these tremors.[2][3][4]
