Chile requests evacuation of Easter Island beaches

The Chilean National Emergency Office (Onemi) issued an alert this Saturday and requested the evacuation of the coasts of Easter Island, the Juan Fernandez Archipelago, San Felix Island and Antarctica after a volcano erupted near the Pacific island of Tonga.

The Chilean Navy’s Hydrographic and Oceanographic Service (SHOA) announced via Twitter a “state of caution” which, according to the scale of the risks handled by this agency, indicates “the possibility of a slight tsunami” in those areas.

The closest island to Tonga is Rapa Nui, better known as Easter Island, located 2,300 miles from the Chilean mainland. Meanwhile, the Juan Fernandez Archipelago and San Felix Island are much closer to South America, about 372 miles apart.

The warning comes hours after an underwater volcano erupted near Tonga in the South Pacific, causing tsunami waves to hit the coasts of this island nation and also triggered alarms in other countries in the region.

Satellite images showed a massive eruption, and a plume of ash, steam and gas billowed like mushrooms over the blue waters of the Pacific Ocean.

Tonga meteorological services said a tsunami warning had been issued for the entire archipelago, and data from the Pacific Tsunami Warning Center showed waves of 2.7 feet were detected.

Authorities in the two neighboring island nations of Fiji and Samoa also issued warnings, telling people to avoid the coast due to strong currents and dangerous waves. The Japan Meteorological Agency said there may be some slight swelling in the waters along the Japanese coast, but it is not expected to cause any damage.

The islands business news site reported that a convoy of police and military forces evacuated King Tubu VI of Tonga from his palace near the coast. He was among the many residents who made their way to higher regions.

The eruption of the Hunga Tonga Hunga Ha’apai volcano was the latest in a series of spectacular eruptions.

More than 1,400 miles away in New Zealand, authorities have warned of a storm surge from the volcano’s eruption.

The National Emergency Management Agency said parts of New Zealand could expect “extraordinarily strong currents and unexpected coastal surges following a major volcanic eruption”.

The volcano is located about 40 miles north of the capital, Nuku’alofa. In late 2014 and early 2015, a series of volcanic eruptions in the area created a new small island and disrupted international air travel to the Pacific archipelago for several days.

Tonga is home to about 105,000 people.
