A natural phenomenon called the 'desert tsunami' has been observed in the United States due to the influence of the earthquake that struck Mexico.
Death Valley National Park in the United States announced on the 22nd (local time) that in the aftermath of the earthquake in Mexico, a 1.2m high wave occurred in the freshwater puddle of the 'devil's hole', a desert cave.
According to the park, a magnitude 7.6 earthquake occurred off the west coast of Mexico at 11:05 a.m. (US time) on the 19th, and shook Death Valley 1,500 miles (2,414 km) 22 minutes later, according to the park.
In the aftermath of the earthquake, the puddles of Devil's Hall began to sway, and at 11:35 a.m. that day, the maximum height of the wave reached 4 feet (1.2 m).
The park recorded the desert tsunami phenomenon observed at the Devil's Hall at the time and published it on its website and YouTube.
Devil's Hall is a limestone cave that is hundreds of feet deep.
In particular, some sections are filled with water, and 175 pubfish, an endangered freshwater fish, live here.
According to the park, pubfish feed on algae that grow on rocks in the water. The tsunami caused the tide to wash away the algae, and the supply of food for pubfish is expected to decrease in the short term.
The park's aquatic ecologist Kevin Wilson said the pubfish habitat has undergone temporary changes, but he expects the fish will tolerate it well.
"Pubfish have survived several (natural) events in recent years," he said.
