EARTHQUAKES are small to awesome

manifestations of energy released in the form of seismic waves and tsunamis as tectonic

plates of the Earth’s crust slowly converge, diverge, or

slide by each other

2014: EARTHQUAKE/TSUNAMI DISASTER OF THE YEAR

THE DISASTER OF THE YEAR OCCURRED IN

IQUIQUE, CHILE

WHERE THE NAZCA PLATE IS SUBDUCTING BENEATH CHILE-PERU

IQUIQUE EARTHQUAKE: M8.2 at 8: 46 pm ON APRIL 1, 2014

IQUIQUE, CHILE EARTHQUAKE (April 1, 2014)

IQUIQUE

Moment Magnitude 8.2

• On April 1, the mega-thrust Iquique earthquake struck off the coast of Chile approximately 95 km (59 mi) northwest of Iquique.

• The main shock was followed by a large number of moderate to very large aftershocks, including a M7.7 event.

IQUIQUE: DAMAGE FROM TSUNAMI

IQUIQUE: NOT THE FIRST EARTHQUAKE EXPERIENCE

REMEMBERING MAY 9, 1877

THE HISTORICAL RECORD

• The 1877 Iquique earthquake occurred on May 9 with a magnitude estimated at 8.5-9.0 on the surface wave magnitude scale.

• The earthquake shaking caused significant damage over most of the coastal parts of the Tarapaca and Antofagasta regions.

THE HISTORICAL RECORD

• The earthquake triggered a devastating 10 m (33 ft) tsunami wave along about 500 km (310 mi) of coast, from Arica in the north to Meiillones in the south.

M6.1 EARTHQUAKE STRIKES NORTHERN YUNNAN PROVINCE

4:30 pm, JULY 22, 2013

LOCATION MAP

About 12,000 homes collapsed in Ludian county

TYPICAL DAMAGE IN ZHAOTONG, THE COUNTY SEAT

VULNERABLE BRICK HOUSES

• The homes that collapsed in Ludian (a population of about 429,000), were mostly old brick houses having little resistance to strong ground shaking.

At least 398 people died and

more than 1,400 were injured

A M6.0 EARTHQUAKE STRIKES NAPA, CA (USA’S WINE COUNTRY)

3:20 AM, AUGUST 24, 2014

• The Bay Area is prone to moderate- to large- magnitude earthquakes because it straddles the boundary between two major tectonic plates — the North American and Pacific plates.

The M6.0 Napa earthquake was the strongest in the San

Francisco Bay area since the 1989 M6.9 Loma Prieta

quake, BUT it only had about 1/30th of Loma Prieta’s

energy release

SOCIOECONOMIC IMPACTS

• Loss of power, gas, and water for 70,000 people.

• Injuries, but no deaths

SOCIOECONOMIC IMPACTS

• Local damage to buildings and houses, infrastructure, and interior contents of homes and stores.

• $ Millions from extensive loss of product (wine)

BEYOND 2014: Communities throughout the

world know why it is urgent for their stakeholders to continue

working on becoming EARTHQUAKE- and TSUNAMI-

DISASTER RESILIENT

Each community knows that it is only a matter of time until the

inevitable earthquake occurs that can expose its physical and

social vulnerabilities

THE REASONS FOR AN EARTH-QUAKE DISASTER TO OCCUR. . .

• The community is UN-PREPARED for the earthquake hazards (GROUND SHAKING, TSUNAMI WAVES, etc.,) that are likely to happen.

THE REASONS ARE . . .

• The community has NO DISASTER PLANNING SCENARIO or PROTECTION SYSTEM OF CODES AND STANDARDS in place as a strategic framework for identi-fication and coordinated local, national, regional, and international countermeasures.

THE REASONS ARE . . .

• The community LACKS THE CAPACITY TO RESPOND to the full spectrum of expected and unexpected emergency situations in a timely and cost-effective manner.

THE REASONS ARE . . .

• The community is INEFFECIVE during recovery and reconstruction because it HAS NOT LEARNED IMPORTANT LESSONS from either the current experience or the cumulative prior experiences.
