Mexico now No. 3 in virus deaths | Pittsburgh Post-Gazette

Mexico now has the third-most COVID-19 deaths in the world, behind the United States and Brazil.

Mexican health officials on Friday reported 688 new deaths, pushing the country’s confirmed total to over 46,600. That put Mexico just ahead of the United Kingdom, which has more than 46,100, according to the tally by Johns Hopkins University.

Some countries are seeing hopeful signs: China reported a more than 50% drop in newly confirmed cases in a possible indication that its latest major outbreak in the northwestern region of Xinjiang may have run its course.

In Hong Kong and elsewhere, however, infections continue to surge. Hong Kong reported more than 100 new cases as of Saturday among the population of 7.5 million. Officials have reinstituted dining restrictions and mask requirements.

M 7.4 Earthquake – 12 km SSW of Santa María Zapotitlán, Mexico

2020-06-23 15:29:05 (UTC) | 16.029°N 95.901°W | 26.3 km depth

Tectonic Summary

The June 23, 2020, M 7.4 earthquake near Oaxaca, Mexico occurred as the result of reverse faulting on or near the plate boundary between the Cocos and North American plates. Focal mechanism solutions for the event indicate rupture occurred on either a shallowly dipping thrust fault striking towards the west or on a steeply dipping reverse fault striking towards the ESE. The depth and focal mechanism solutions of the event are consistent with its occurrence on the subduction zone interface between these plates, approximately 100 km northeast of the Middle America Trench, where the Cocos plate begins its descent into the mantle beneath Mexico. In the region of this earthquake, the Cocos plate moves approximately northeastward at a rate of 60 mm/yr.

While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip over a larger fault area. Reverse faulting events of the size of the June 23, 2020 earthquake are typically about 70 x 35 km in size (length x width).

Oldest and largest ancient Maya structure found in Mexico – Reuters

WASHINGTON (Reuters) – Scientists using an aerial remote-sensing method have discovered the largest and oldest-known structure built by the ancient Maya civilization – a colossal rectangular elevated platform built between 1,000 and 800 BC in Mexico’s Tabasco state.

The structure, unlike the soaring Maya pyramids at cities like Tikal in Guatemala and Palenque in Mexico erected some 1,500 years later, was not built of stone but rather of clay and earth, and likely was used for mass rituals, researchers said on Wednesday.

Located at a site called Aguada Fenix near the Guatemalan border, the structure measured nearly a quarter mile (400 meters) wide and nine-tenths of a mile (1,400 meters) long and stood 33 to 50 feet (10 to 15 meters) high. In total volume, it exceeded ancient Egypt’s Great Pyramid of Giza built 1,500 years earlier.
