According to the USGS, an 5.9 earthquake was recorded at Puerto Acosta, near the shore of Lake Titicaca near the Peru/ Bolvia border at 3:30pm local time Wednesday.
The quake, which was 95 km (60 miles) E of Juliaca, Peru and 160 km (100 miles) NW of La Paz, Bolivia occurred at a depth of 250.2 km (155.5 miles) and is believed to have not felt in the surrounding areas. There are no reports of damage or injuries at this time.
Frank James at NPR asks the question I have as well: “Three major quakes occurring in a 24-hour period is making many people ask if there’s any connection between the events. We’re trying to get a good scientific answer to that.”
