translated from Spanish: Earthquake hit the islands of Java and Sumatra in Indonesia: tsunami warning

A 6.8 magnitude earthquake shook the sea in the southern strait that separates the Indonesian islands from Java and Sumatra, the most populous islands in the archipelago, and Indonesian authorities warned of a potential tsunami.
The U.S. Geological Survey (USGS), which records seismic activity worldwide, located the hypocenter of the earthquake about 90 kilometers southwest of Banten Province in Java and 42 kilometers deep.
The Indonesian seismological service, BMKG, calculated the magnitude of the earthquake at magnitude 7.4, although it is unknown at the moment whether there may be injuries or deaths.
In addition, BMKG warned that a possible tsunami could produce waves up to three meters high in several areas of the islands of Java, Sumatra and Panaitan, so it asked the population of those places to move to high areas.
Indonesia sits on the so-called Pacific Ring of Fire, an area of high seismic and volcanic activity with 127 active volcanoes with some 7,000 earthquakes, mostly moderates, each year.
In September last year, a magnitude 7.5 earthquake shook Sulawesi Island and struck a tsunami that killed more than 2,000 and 200,000 displaced in the towns of Palu and Donggala.
