Using games to mitigate people risk in cyber security

Having long languished as an underappreciated problem for organisations, cyber security is today widely recognised as a critical business risk, with 74% of UK companies rating it as a high priority for senior management. However, increased recognition does not necessarily mean that the problem is better understood. Cyber security is replete with impenetrable jargon and complicated concepts which often lead to it being incorrectly considered a problem for technologists that can be solved by IT departments.

Are you ready for peak 2018 hurricane season?

While current predictions indicate a relatively quiet hurricane season, particularly in comparison to last year, it only takes one major hurricane making landfall in a built-up area to create a significant loss, as we saw with Hurricane Andrew in 1992 – a relatively quiet season overall. So, with the peak months still ahead of us (hurricane season ends November 30), what can we expect this year?

Within this volume, two losses stood out, an estimated $82 billion in property and direct business losses, and up to $30 billion in fire damage.

How to model a windstorm

Storm Angus hit the U.K. earlier this month (also known as Nannette as designated by the Free University of Berlin). Although insurance industry losses are not expected have much impact on the reinsurance industry, the storm did produce high winds and heavy rain over the U.K., especially for Wales and Southwest England, and into parts of France.

After Amatrice: Unlocking seismic hazard. A race against time.

Italy’s earthquake in August raised questions about whether the seismic risk in the region has increased. Amatrice is an area of historical seismic activity where seismic hazard and risk studies carried out a few years ago anticipated that a future earthquake of this size was possible, given a relative period of inactivity.

Matthew

The deadliest hurricane in 11 years has struck around a fortnight ago. After tearing a path through the Caribbean, across Haiti and Eastern Cuba, through the Bahamas and then along the east coast of the U.S., it was finally absorbed into a frontal weather system heading eastwards across the Atlantic.

Winter storms and hurricanes, all of an afternoon

The Willis Research Network workshops and seminars are always interesting events, and this year’s London seminar was no exception. Held on the 22nd of September, we focussed on wind extremes, specifically seasonal hurricane forecasting and simulating European winter-storm footprints.

Has hurricane season peaked?

As an ex-weather forecaster, and redoubled through my role working with the Willis Research Network, I have always been involuntarily drawn toward extreme weather. For me, the peak of hurricane season always brings both excitement and anticipation at the prospect of witnessing one of the most powerful forces of nature, but also anxiety due to the possibility that a catastrophic storm might make landfall and strike a population area.

Could a tsunami wipe out the U.K. coastline?

Tsunami is a risk unlike any other natural catastrophe: it has the potential to dramatically change the landscape in a very short space of time, leaving devastation in its wake. And as an island, the U.K. is potentially vulnerable to this natural catastrophe. But how great is the risk of a tsunami hitting the U.K. and how frequently could it happen?

A “drought” of major hurricane landfalls? Science weighs in.

Hurricane season is here. Tropical Storm Colin is the third named storm in the Atlantic basin this year, and has brought rough seas, heavy rain and flooding to Florida and parts of the east coast of the U.S. So far all three storms have been fairly weak without much impact.

Progress in Assessing Tsunami Risk on a Global Scale

Tsunamis produce some of the greatest losses to lives and livelihoods of any disaster. They ignore country borders, bringing chaos and destruction indiscriminately. These rare events are difficult to study, but we have learnt many valuable lessons from two of the biggest tsunamis that have occurred in the last decade: the 2004 Indian Ocean tsunami, and the 2011 Great East Japan tsunami.

Strongest El Niño in Decades

Seasonal forecasting is a developing science. Skill is required for the scientific production of the forecast, but also in interpreting the information. However, if there is ever going to be a good time to check these long range forecasts, it is now.

Climate Resilience and Graceful Failure

Extreme weather events are opportunists. They strike indiscriminately, and selectively expose the parts of society that are underprepared and most vulnerable. We see the lack of resilience to extreme events in the most susceptible regions time and time again in the loss of life and livelihoods and the destruction of properties and businesses.

Interactive Map of Hurricane Katrina

Only ten years ago the city of New Orleans, “the Big Easy” was left battered and broken by ravaging winds and unyielding storm surge brought in by Hurricane Katrina. Even though it was a highly anticipated and well-forecast storm, Katrina nonetheless caused unmitigated chaos and overwhelmed the city’s coastal defences and the capacity of its emergency responders.

Seasonal Climate Impact Prediction

We couldn’t possibly have anticipated Hurricane Sandy in advance of the season, or could we? Seasonal climate forecasts have been produced routinely for many years yet their uptake by the industry has been slow. Given that insurers and reinsurers live and die by high-impact weather and climate events why is this?
