Significant Quakes Hit Alaska, Mexico



M6.0 earthquakes hit Alaska and Papua New Guinea within 4 hours


The first of the two struck 92km WSW of Chernabura Island in Alaska at 14:16 UTC on July 19, 2018 and at a depth of 17.1 km (10.6 miles). There are about 400 people living within 100 km (62 miles). A tsunami was not produced. This earthquake is expected to have a low humanitarian impact based on the magnitude and the affected population and their vulnerability.


4 hours later, at 18:30 UTC, the second magnitude 6.0 earthquake hit 95km W of Kandrian, Papua New Guinea at a depth of 31.2 km (19.4 miles). Nobody has reported the quake in the area as less than 3000 people live in the region. A tsunami was not produced.
But still… Two strong earthquakes with magnitude => M6.0 








Thursday, July 19, 2018, 15:55 - A magnitude 6.0 earthquake struck to the south of the Alaska peninsula early on Thursday, but the National Weather Service said no tsunami warning has been issued.
The quake was centered about 62 miles (100 km) south-southwest of Sand Point, Alaska, at a depth of 10.6 miles, according to the U.S. Geological Survey.
"No tsunami warning, advisory, watch or threat," said officials from the National Weather Service, a unit of the National Oceanic and Atmospheric Administration.

The quake was far milder than a magnitude 7.9 earthquake that struck the Gulf of Alaska in January, triggering tsunami alerts for the U.S. West Coast and Canada as well as spurring evacuations in coastal Alaska and warnings as far south as California.
The largest earthquake ever recorded in the United States was also in Alaska, a magnitude 9.2 temblor in March 1964, causing tidal waves of more than 100 feet (30 m) high that killed 131 people.










A 5.7 magnitude earthquake rattled southern and central Mexico on Thursday. There were no immediate reports of damage or injuries.
Workers at some Mexico City office towers temporarily evacuated their buildings, but quickly re-entered after the swaying stopped.
The U.S. Geological Survey said the quake occurred around 8:30 a.m. local time and was centered near the city of Huajuapan de Leon in southern Oaxaca state, about 140 miles southeast of the capital.
The federal civil defense agency said there were no immediate reports of incidents.
