I was in the supermarket and everything swayed,” Carla Chavez told the Associated Press news Earthquake Early Warning agency by phone from David, the capital of Panama’s Chiriqui province near the quake’s epicentre. “Merchandise fell on the floor. Everything happened so fast.”
President Juan Carlos Varela said on Twitter earlier that just one person was hurt, in Puerto Armuelles, and also reported damage to homes and businesses.
Panama’s National Civil Protection Service said on Twitter that walls cracked at a hospital and two Earthquake Early Warning supermarkets in Changuinola in Bocas del Toro province.
There was no tsunami alert issued from the Pacific Tsunami Warning Center.
Sigifredo Perez, head of operations for Costa Rica’s National Commission of Emergencies, said no major damage or injuries had been reported in the country.
The exhibit delves into the topics of earthquakes, tsunamis and how engineers are working to protect people from those types of disasters.
There are several displays, including an earthquake simulator, a tectonic plate puzzle and a tsunami tank. The exhibit also features some local history with a display on the big Helena earthquake in 1935 that killed two people.
“160 million people in the United States alone are impacted by earthquakes on some level or live in a zone where they may be impacted, so I think it’s relevant for a lot of people,” said Kelly Posewitz, ExplorationWorks executive director.
The exhibit was sponsored by the National Network for Earthquake Engineering Simulation Earthquake Early Warning with additional funding from the National Science Foundation.
NEES allowed Sciencenter in Ithaca, New York to develop the display. Kathy Krafft with Sciencenter flew out to Helena to help assemble the exhibit at ExplorationWorks.
“They’re hoping that we will not only share about earthquakes and engineering and the science but also inspire people to understand how it affects them and maybe we’ll inspire some future engineers,” Krafft said.
The “When the Earthquake Early Warning ” exhibit opened Friday at 10 a.m and will be on display through September.
A 3.1-magnitude earthquake struck about 45 miles east of San Antonio Tuesday morning, marking the third time a quake was recorded in the region in the past week.
The United States Geological Survey recorded the earthquake just outside the city of Smiley in Gonzales County before 6 a.m. The epicentre of the Earthquake Early Warning was about 3 miles below the surface, the geological survey said.
An earthquake of this magnitude can range from being felt by only a few people to being noticeably felt, especially by people on the upper floors of buildings, the USGS website says. Anything with a magnitude of 5.5 or higher tends to be more of a concern.
Don Blakeman, a geophysicist at the USGS’ National Earthquake Information Center in Denver, said there’s a strong possibility Tuesday morning’s Earthquake Early Warning earthquake was induced by injections of fracking fluids into the ground, but further study would be needed to know for sure.
“This area, in particular, if you look at it in on Google Earth is just peppered with well pads, lots and lots of oil and gas wells,” Blakeman said when reached by phone Wednesday.
The USGS says the largest documented earthquake induced by fluid injection was a 5.8-magnitude Earthquake Early Warning quake in central Oklahoma on Sept. 23, 2016. Earthquakes with magnitudes between 4.5 and 5.0 have been induced by fluid injection in Arkansas, Colorado, Kansas and Texas as well.
If you felt this earthquake, Earthquake Early Warning the USGS asks that you report it on its website.
