On April 10, 2018, three earthquakes around the world were in the news. The largest was in South America (see video below), the second largest was in Europe, with the smallest in North America.

But, residents in Oklahoma have felt 1,047 earthquakes in the past 365 days, only one of which made national news this week. We don’t usually mention the Oklahoma earthquakes, because they are far from all cruise ports, including those cruise ports along inland rivers. But, today they get a mention below.

The largest earthquake today was at 10:19:34 UTC, when a 6.2 quake struck 54 kilometers from Ovalle, Chile .   The U.S. Geological Survey (USGS) said the quake struck about 34 miles (54 kilometers) southwest of Ovalle, Chile at 7:19 a.m. local time. The USGS said it was detected at a depth of 47 miles (76 kilometers).

Ovalle is a city in the Coquimbo Region of Chile, founded in 1831 as a settlement. It has a population of more than 113,000 people. The name Ovalle was chosen to honor to Chile’s vice-president, José Tomás Ovalle. Ovalle is the capital of the Limarí Province.

The nearest cruise port is Valparaiso (Santiago) Chile 373 km to the south.

The quake shook the capital of Santiago and other cities, causing buildings to sway. But Chile’s emergency services office said no damages to infrastructure were immediately reported and dismissed the possibility of a tsunami on the country’s long coast.

  • Earlier today, a magnitude 4.7 quake shook residents and structures near the town of Macerata, Italy in the Marche region. They are still recovering from powerful quakes on October 30, 2016 that caused widespread damage but no deaths, and was felt in the neighboring regions of Umbria and Lazio. The earthquake today, caused the partial collapse of a 17th century bell tower that had been damaged in 2016.
  • Also earlier today, a 3.0 earthquake which struck near Fontana, California just before 6:30 a.m. It’s the latest quake since a bigger quake rattled most of the Southern California region on April 5, 2018.

On  February 27, 2010 a devastating 8.8-magnitude quake struck off the coast of south-central Chile. It was one of the strongest ever recorded, and the tsunami it unleashed, killed more than 500 people and destroyed more than 200,000 homes.

Oklahoma has been rocked by very shallow mild to moderate earthquakes for many months, ranging this week from 1.7 to 4.5 (yesterday),  which some say are the result of “fracking”.  In Oklahoma, there have been 2 earthquakes in the past 24 hours, 28 earthquakes in the past 7 days, 79 earthquakes in the past 30 days and 1,047 earthquakes in the past 365 days.

According to the The United States Geological Survey (USGS) website, which says, “wastewater disposal wells typically operate for longer durations and inject much more fluid than hydraulic fracturing, making them more likely to induce earthquakes. In Oklahoma, which has the most induced earthquakes in US, only 1-2% of the earthquakes can be linked to hydraulic fracturing operations. The remaining earthquakes are induced by wastewater disposal.”

In Oklahoma, less than 10% of the water injected into wastewater disposal wells is used hydraulic fracturing fluid. Most of the wastewater  in  Oklahoma is saltwater that comes up along with oil during the extraction process.
