Earthquakes Rock the Gulf of California

Two earthquakes rocked Mexico last night in a wave of recent global earthquake activity.

Two earthquakes shook Mexico City late Wednesday night and early Thursday morning, causing buildings to sway and forcing citizens to evacuate high rise apartments. 

The U.S. Geological Survey reported that the first of the two quakes had a 6.9 magnitude and hit the waters between the Baja peninsula and the northern slate of Sonora.  

Residents in Sonora’s capital city of Hermosillo woke around 12:15 a.m. to their beds moving and their ceiling fans shaking.  Panicked residents of the state’s largest city clogged phone lines in confusion, but the director of emergency services in Sonora, Luis Enrique Cordova said no major damages were reported in the region.

The earthquake came just hours after 6.4 quake hit a sparsely populated area in the mountains of western Mexico Wednesday night.

No tsunami warnings were raised but the quakes were felt as far north as Tucson, Arizona.

Mexico City is not a stranger to strong tremors.  Three weeks ago a powerful 7.4 magnitude quake hit southern Mexico leaving hundreds of damaged homes and at least two dead in the nation’s capital.

Mexico’s seismological service said that last month’s quake was followed by close to 400 aftershocks.

However, Mexico has not been alone in feeling the effects of the Earth’s tectonic plates as earthquake activity has been high across the world over the last few days.

Two massive quakes struck off the coast of Indonesia Tuesday morning.  The first, an 8.6 magnitude, was followed by an 8.2 aftershock that left five dead according to disaster officials. 

The activity in Indonesia sparked a tsunami alert by the Pacific Tsunami Warning Center in Hawaii causing people to evacuate coastal areas.  However, the alert was cancelled a few hours later.
