Tropical Cyclones and Thunderstorms

On 1 November, we held our second London-based Willis Research Network (WRN) seminar of the year. After the last seminar in February, which focussed on seismic and volcanic risk, our latest meeting was a chance to showcase our latest WRN research into weather and climate related risks, following on from last year’s similar event. Our ongoing research partnerships have given us plenty of inspiration to build a relevant agenda.

Can changes in Earth’s rotation be used to forecast earthquakes?

Recent media reports have described a proposed relationship between earth rotation and the number of large (M>7) earthquakes. In contrast to these headlines and their exaggerated claims, the conclusions they report are uncontroversial and are based on a straightforward analysis of publically available data.

Willis Research Network Newsletter: Issue No. 4 – Autumn 2017

As we put together our latest newsletter from the Willis Research Network (WRN), it’s clear that the current Hurricane Season is well and truly making its mark. Hurricane Irma and now Maria have wreaked havoc across the Caribbean and South East U.S.A, only the 6th time on record that multiple Category 5 storms have developed in the Atlantic basin.

A tale of three hurricanes

All eyes were on Houston as the unprecedented rainfall brought by Harvey turned much of the nation’s fourth largest metropolitan area temporarily into a lake. Then came Irma, and we held our breath as the giant storm wound a path that inflicted terrible damage but mercifully fell short of the worst-ever predictions that preceded it for much of Florida. And then Maria, hammering some of the islands that Irma had spared.

Risk megatrends in a changing world

Few businesses today have the luxury of operating within a geographic or industry bubble. Around the world, interconnected political, economic and commercial factors influence the direction and destiny of companies, both large and small, across a range of sectors. As a result, risks that once could be understood and managed locally have become ever-more challenging and global, while new risks seem to appear almost daily.

Devastating natural disasters continue to pummel Mexico. What does it mean and what’s next?

While Mexico is still counting the victims and assessing the damage from the last earthquake that struck the capital, estimated to be up to $10bn according to the USGS, we reflect on how the country is being hit left, right and centre by natural catastrophes.

Are Mexico’s two major earthquakes related, and what could happen next?

A burning question in all our minds is whether the M=8.1 Chiapas earthquake in any sense triggered the M=7.1 shock twelve days later and 600 km (360 mi) away. Their tantalizing connection is not just time and distance, but also their similar depth and mechanism.

M=6.6 earthquake near Greek andTurkish tourist hotspots likely ruptured the Gökova Fault

The large earthquake struck at 1:40 am local time near the tourist meccas of Kos, Greece, and Bodrum, Turkey. It was preceded by a M=2.5 shock approximately 20 minutes before the mainshock. The earthquake occurred at a relatively shallow depth of 10 km, and strong shaking lasted for about 20 seconds.

Progressive approach to eruption at Campi Flegrei caldera in southern Italy

Unrest at large calderas rarely ends in eruption, encouraging vulnerable communities to perceive emergency warnings of volcanic activity as false alarms. A classic example is the Campi Flegrei caldera in southern Italy, where three episodes of major uplift since 1950 have raised its central district by about 3 m without an eruption.

Earthquake aftershock zones are actually global

Triggering occurs as a result of the redistribution of stress induced by an earthquake. Differentiating triggered events from normal background seismicity is a key objective in studies of earthquake triggering. During the 1990s there was substantial evidence that earthquake sequences, spaced in time and space, are being triggered by the previous events.

What risks will emerge in 2017?

A look at the emerging risks for 2017 reveals two clear touchpoints: people and politics – and especially politics. Risk experts in areas ranging from human capital to transportation, from Washington, DC to Brazil are looking at the broad implications of political trends that could have profound effect on the global economy. The trends toward populism, protectionism and deregulation could change the risk profiles for many industries.
