USGS seismologist Dr. Walter Mooney (with white hat in left hand) together with residents of a village were a seismographic station was installed, following the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010.

Vehicles crushed beneath the second story balcony of the Hotel D'Haiti located in Port-au-Prince. This entire hotel with more than 50 rooms was destroyed as a result of the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010.

A real view of Port-au-Prince, Haiti, looking southeast with the port in the foreground and main city residences and other buildings showing as white in the center. Many of the neighborhoods with the heaviest destruction from the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010 are included in this view.

Collapsed multi-story building occupied by "Centre D'Edudes La Concorde" in Port-au-Prince, a result of the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010. An examination of the adjacent buildings indicates that this structure was either two or three stories tall.

Collapsed multi-story residence in Port-au-Prince following the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010. The weight of heavy concrete floors and roofs was often too great for the modest strength in support columns, as evidenced here.

Not all places of business or residence collapsed or suffered serious damage following the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010. Here, an auto parts store in Port-au-Prince is open for business on January 28, 2010, sixteen days after the earthquake. This street still contains trash and litter due to lack of public services.

Massive rock slides were caused by strong ground shaking during the main shock of the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010 and several of the stronger aftershocks. This mountain road leads north to the city of Dufort, located near the larger city of Leogane.

This young girl stands in front of a massive crack in the road on highway Nationale 2 near Petit Gaove, Haiti. The highway collapse was caused by lateral spreading of the underlying soil during the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010.

The epicenter of the magnitude-7 earthquake that struck Haiti on Jan. 12, 2010 is shown in this photo below the highest peak in the center of the view. The mapped Enriquillo fault zone comes towards the viewer in the low-lying hills and passes north (left) of the deforested clearing in the foreground.

The active front of a pāhoehoe flow near the intersection of Pikake and Warrior Street, in the Royal Gardens subdivision. The road in the lower portion of the photo is the last remaining piece of Pikake Street.

A relatively clear view into Pu`u `Ō `ō crater, looking NNE. Several persistent fuming sources are visible in the crater, including the source of a small lava flow near the crater's center. The dark area trending east-west at the bottom of the crater is a small lava flow that erupted between January 13 and January 19.

The 'a'ā flow that was active in the upper reaches of Royal Gardens subdivision on January 19 had stalled by today. The flow can be identified as the dark flow terminating near the center of the photograph. The flow front had extended well into the subdivision, almost reaching the level of Plumeria Street.

Bluff erosion during the 2009–10 El Niño undermined the Great Highway guardrail at Ocean Beach, San Francisco, California. The shoreline eroded, on average, 55 meters that winter, leading to lane closures on the highway and an emergency $5-million revetment along the base of this bluff.

Bluff erosion during the 2009–10 El Niño undermined the Great Highway guardrail at the southern end of Ocean Beach, San Francisco, California. The shoreline eroded, on average, 55 meters that winter, leading to lane closures on the highway and an emergency $5-million revetment along the base of this bluff.

Bold numbers are the years of moderately large (larger than about M7) historical earthquakes written next to their approximate location. Asterisk - Location of the January 12, 2010 earthquake.

Severe bluff erosion, along the southern end of Ocean Beach, San Francisco, California, including damage to the guard rail of the Great Highway (Calif. Hwy.1). The severe winter erosion led to lane closures of the highway and an emergency, $5 million revetment along the base of this bluff.

Two HVO geologists are standing on the east rim of Pu`u `Ō `ō cone, triangulating the depth of several degassing vents inside the crater. An infrared camera is being used to see the vents through the fume. The plume in the background is coming from the east wall vent.
