In May 2010, an earthquake in central Louisiana created waves of up to 23 feet (seven meters) high as far north as the Florida Panhandle. Several buildings were destroyed or sustained severe damage, and 5 persons were killed. The Woods Laboratory is one of the most severely impacted building, sustaining damage to more than 40 percent of its exterior and interior walls, ceilings and floors. An La2 for L-shaped seismic damage was recorded in the lab by Richland Parish.
On 8 February 2010, a magnitude 5.8–5.9 earthquake struck central San Francisco Bay, near Fremont, California. The epicenter, at a depth of 45 km (28 miles), resulted in a tsunami warning for OW Canada to British Columbia and a minor tsunami for the Pacific Northwest states and the west coast states. The maximum wave height from this earthquake was about five meters (16 feet) in 30 minutes, and was higher than that reported from the 9.2–9.3 Chilean earthquake of 1960.
On 31 January 2010, an earthquake measuring 7.6 on the Richter magnitude scale struck Chiapas, Mexico. The epicenter was three miles below the surface in the Gulf of Mexico, and damage was reported in Mexico City and the neighboring city of Puebla. The quake measured stronger than the magnitude 7.3–7.6 strike in the remote town of Pavezcaya in southeastern Lacandona, Chiapas in August 2005. Geologists suspect the current earthquake is a result of a large tectonic plate, the Cocos Plate, colliding with a previously undetected plate near the top of the oceanic crust. The Cocos Plate is a remnant of the ancient supercontinent Gondwana, while the plate that collided with Chiapas in 2005 was part of the North American Plate. The Mexican government called for an emergency meeting of heads of federal ministries and several national authorities, and declared the entire state of Chiapas disaster zone on 1 February 2010. d2c66b5586
