While it is still not possible to predict the exact date, location and
magnitude of seismic events there are plenty of opportunities to make
society more resilient against this catastrophic threat.
On June 22, 2021, Peru experienced an earthquake of magnitude 6.0 on the Richter scale. Despite its strength and the fact that it was followed by
several aftershocks, it only caused limited damage and no deaths or serious injuries.
Peruvians were lucky that the epicentre was off the coast of Mala and
not closer to the capital Lima with its 11 million inhabitants and many
self-built constructions unlikely to withstand strong earthquakes. Only
a few weeks later, on July 30, Peru experienced an earthquake of magnitude 6.1 (opens a new window) on the Richter scale near Sullana, on the northern coast of Peru with dozens injured, some material damage but thankfully no deaths.
Peru and Lima are highly vulnerable to earthquakes. The Andes
mountain range is the youngest globally and subject to continuous
transformation, driven by the collision of plates, which is the trigger
for earthquakes. A large tectonic deformation is accumulating off the
coast of Peru that can give rise to a seismic movement exceeding the
magnitude of 8.5. If such an earthquake occurred next to the
metropolitan area of Lima and Callao, constructions in Lima would need
to resist a tremor that could last five minutes.
The 2015-2025 City Risk Index produced by Lloyd's indicates that the
Peruvian capital is the city with the highest risk of damage worldwide
in case an earthquake of between 8.5 and 8.8 degrees occurs. Economic
losses in Lima could reach US$35,530 million (opens a new window) without including the risk of a tsunami, according to the report.

The destruction and number of fatalities an earthquake causes depends
not only on the earthquake parameters themselves (magnitude, distance,
duration) and the local soil conditions, but also on the quality of the
affected buildings and the governments’ catastrophe response plans.
Disasters are preventable
In January 2010, a quake measuring 7.0 in Port-au-Prince, Haiti left a
death toll ranging from around 100,000 to more than 300,000 people. A
month later, the Maulé earthquake struck near Santiago, Chile. Despite a
magnitude of 8.8 on the Richter scale, it caused much fewer fatalities
with 525 deaths. Chile had protected the population through a
combination of monitoring, early warning systems and, critically, strong
The economic consequences of earthquakes also differ depending on
insurance penetration, the governments’ financial strength and
protection. While Haiti was still rebuilding broken infrastructure eight
years after the event, Chile was able to recover much more quickly in
part due to reinsurance payouts.
Stronger earthquakes frequently cause knock-on effects with high loss
potentials. These include seismic sea waves (tsunamis), such as those
that caused a devastation in the Sumatra quake of 2004 or in the Japan
quake of 2011. The Fukushima nuclear disaster of 2011 in Japan was
triggered by a tsunami following an earthquake — With 210 US$ bn it has
been the costliest natural catastrophe of all time, according to Munich Re (opens a new window). Earthquakes can also cause landslides, subsidence and ground liquefaction, which can produce extremely high losses.
Regions most at risk
Earthquake risks are concentrated around the Pacific Ocean: More than
80% of earthquakes occur in this region and 90% of the most important
volcanic chains are located around the Pacific plate. The region is
therefore also known as the Pacific ring of fire.
Although earthquakes continue to kill thousands and devastate local
economies, governments have the ability to reduce their impacts
Governments can implement and enforce national building codes that
stipulate engineering design features to protect buildings against
earthquakes. Such earthquake-related regulations can save lives by
ensuring a high level of structural stability. A new generation of
building codes introduced in the US, Japan and New Zealand, can not only protect against fatalities but also aims to reduce property damage.
Sophisticated new technology can make buildings withstand earthquakes. Base isolators are like shock absorbers between the building and the ground motion, letting a building slide back and forth while remaining upright during a quake. This significantly reduces the movement of buildings.
Construction plans should also include the selection of appropriate
sites to avoid highly exposed areas. Alternatively, the building structure needs to be adjusted to the specific risk level. Buildings that do not comply with stricter regulation will need to be retrofitted or rebuilt. The implementation of a culture of prevention is essential for lowering the risk of disasters. Investing in risk reduction can also improve the insurability of buildings.
Develop a culture of prevention through:
Identification of safe areas
Protecting against the residual risk
Earthquake insurance is usually offered as a supplement to
traditional fire insurance cover or as a component of a policy
extension. Such protection includes deductibles to limit insurers’
indemnity and loss accumulation.
The penetration rate of earthquake insurance worldwide is rather low,
particularly in poorer countries, leaving the majority of the population vulnerable to the financial impact of quakes and reducing the speed of reconstruction.
Earthquake coverage can be included via the following insurance plans:
Property all risk
Parametric risk transfer
Contractors equipment insurance, CAR, EAR, EE.
Extension of coverage for earthquakes in agricultural insurance
The infrequency of major earthquakes and the high cost of insurance in high-risk zones have often made it difficult to encourage sufficient demand for insurance. Further, traditional insurance solutions often include a potentially lengthy claims settlement process, which can create cash flow problems for property owners, companies and organisations.
New parametric insurance solutions designed for seismic events can offer more transparency and automated, immediate payments. Such protection can be customised via pre-define triggers and payout amounts per location or defined area. Payouts are triggered automatically when a specified quake intensity is exceeded at a certain location. Pre-agreed independent third parties provide the data needed to trigger the cover. Parametric products typically do not include a deductible.
Because the insurability of earthquake losses faces a number of challenges, some governments have established public earthquake (re)insurance arrangements to support broader insurance coverage, in
particular among households. Nevertheless, a high-level of underinsurance of earthquake risk remains in most parts of the world. This financial protection gap for earthquake risk leaves households and businesses – and ultimately governments – vulnerable to losses stemming
In the aftermath of an earthquake, it is important to leverage opportunities to “build back better”. Governments should also take advantage of continually improving quality and availability of seismic
maps and earthquake models to more accurately identify potentially
active fault lines. When actively managing the earthquake risk, governments can support insurability and reduce the costs for emergency
response and recovery, repair of public assets and any financial assistance or compensation provided to those affected. Such costs can have a material impact on public finances.
Government involvement is key in supporting the insurability of earthquake risk.
