seismic susceptibility
When dealing with things that might go horribly wrong, and particularly when addressing the general public, engineers like to avoid words like "hazard" and "risk" since those words are seen by many as "positive", in a negative sense, i.e. something bad will go wrong. "Susceptibility" on the other hand is more "neutral" - there's a possibility, it might or it mightn't happen.

143,000 ghits for "susceptible to earthquakes"
1160 "earthquake-susceptible"
which compares not too badly with the 1100 "alea sismique".
susceptible ... 1. Capable of taking, receiving, being affected by, or undergoing something.
[SOED]
An earthquake-prone area is one which is susceptible to suffer from earthquakes.
As for use by professionals in the field, the "Susceptibility Map of the San Francisco Bay Area" here, showing "very high" to "very low" liquefaction susceptibility was produced by the US Geological Survey

Even though that’s the most powerful earthquake we know about in New England, Ebel [Boston College Professor of Geophysics] wouldn’t rule out the region has experienced a 7.0 and could again. But, he said, most seismologists would say THE REGION IS NOT SUSCEPTIBLE TO EARTHQUAKES AS LARGE AS AN 8.0. [ ... ] CALIFORNIA IS DESERVEDLY NOTORIOUS FOR ITS EARTHQUAKE SUSCEPTIBILITY, Ebel said. “If I recorded earthquakes in California for one year and then came to New England, I’d have to record for 100 years to get the same amount of data,” Ebel said.

I imagine that were New England to be hit by a mag.8 earthquake, despite being "NOT SUSCEPTIBLE TO EARTHQUAKES AS LARGE AS AN 8.0", it would in fact prove to be highly susceptible to earthquakes in the sense that there would be lot of damage!

[obviously written before the Christchurch earthquakes of September and February]
Note that as these examples show, "earthquake susceptibility" can refer not only to the "proneness" of an area to be hit by an earthquake (irrespective of any damage caused), but also to the likelihood of damage occurring as the result of an earthquake.

www.tokyoreporter.com/2008/06/30/tokyo-underground/
Reducing the number of overhead wires will not reduce the likelihood of an earthquake striking (earthquake susceptibility – susceptibility of earthquakes occurring or "capability of undergoing an earthquake", to take up the SOED expression), but it might reduce the likelihood of power outages (earthquake susceptibility = susceptibility of power outages occurring as a result of earthquake).
Prior to last September, Christchurch, NZ, was not generally regarded as being susceptible to (being struck by) major earthquakes. It has since been demonstrated that while - with two notable exceptions – its modern buildings are not susceptible to (likely to be seriously damaged by) earthquakes and nor are most homes (timber frame) of any age (with the exception of chimneys and brick-veneer walling), its unreinforced brick buildings were extremely susceptible to earthquakes, and collapsed on a massive scale.

ALÉA ... Événement qui dépend du hasard; éventualité presque toujours défavorable (le plus souvent au plur. et accompagné d'un compl.) : Ce inconvénient compte parmi les aléas du métier (syn.

Saying that aléa necessarily means "hazard" is a little categorical. From the word we get aléatoire, where the only notion of risk is the chance/possibility/risk that something might or might not happen. I suspect the UCLaval people are trusting a false friend. Aléa is no more "hazard" than aléatoire is "hazardous".
Note that while risque sismique (sing. & plur.) gets a little over 200,000 ghits, aléa sismique (sing. & plur.) gets ten times fewer, at 19,000. Assuming the author masters his language, why did he choose aléa rather than risque? For the simple reason that they are two different things, maybe:

Regional seismic risk in British Columbia — damage and loss distribution in Victoria and Vancouver
Tuna Onur, Carlos E. Ventura, and W.D Liam Finn
Abstract: This paper presents the results of regional seismic risk assessment studies that were carried out for two cities in southwestern British Columbia, Vancouver and Victoria. Ground shaking intensity in the area was obtained using the seismic source zones delineated by the Geological Survey of Canada for a probability level of 10% chance of exceedance in 50 years. Building inventories were compiled by aggregating data from sidewalk surveys as well as municipal databases. Modified Mercalli intensity-based damage matrices that relate the level of ground shaking to the amount of damage expected in different types of structures were used to estimate damage to structural and non-structural components of buildings. Estimated damage and loss distributions were mapped on a block-by-block basis. The historic sections of the cities were estimated to have damage levels between 10% and 30% of the replacement cost, while in the rest of the cities the estimated damage was generally in the 5% to 10% range. The results show the estimated economic loss distribution is considerably different from the damage distribution. Although the older neighbourhoods of the cities are expected to suffer highest amount of damage, the highest amount of economic loss is estimated to occur in areas with concentration of concrete high-rise buildings.
Key words: seismic hazard, seismic risk, vulnerability, earthquake, damage, loss, probability, modified Mercalli intensity.
Résumé : Cet article présente les résultats d'études d'évaluation des risques sismiques régionaux qui ont été effectuées pour deux villes du sud-ouest de la Colombie-Britannique, Vancouver et Victoria. L'intensité des secousses sismiques dans la région a été obtenue en utilisant les zones de sources sismiques délimitées par la Commission géologique du Canada pour un niveau de probabilité de 10 % de dépassement en 50 ans. Les immeubles ont été inventoriés en colligeant des données provenant de relevés des trottoirs ainsi que des bases de données municipales. Les matrices des dommages basées sur l'échelle de Mercalli modifiée, laquelle relie le niveau de secousses sismiques à la quantité de dommage attendue pour divers types de structures, ont été utilisées pour évaluer les dommages aux composantes structurales et non structurales des immeubles. Les dommages estimés et les étalements des pertes ont été cartographiées en se basant sur les îlots urbains. Les secteurs historiques des villes ont été évalués comme ayant des niveaux de dommages entre 10 et 30 % du coût de remplacement, alors que le dommage estimé dans les autres secteurs des villes se situait généralement dans la plage de 5 à 10 %. Les résultats montrent que l'étalement estimé des pertes économiques diffère considérablement de l'étalement des dommages. Bien que l'on s'attende à ce que les plus vieux secteurs des villes subissent le plus de dommages, il est estimé que la plus grande perte économique surviendrait dans les zones présentant des concentrations d'immeubles en béton de grande hauteur.

Discussion
Earthquake Hazard and Risk
Hazard and risk are two fundamentally different concepts. In general terms, hazard is a phenomenon that has potential to cause harm. Phenomena are both natural and man-made. For example, earthquakes, hurricanes, tornadoes, and floods are natural hazards; whereas car crashes, chemical spills, train derailments, and terror attacks are man-made hazards. Risk, on the other hand, is the probability (chance) of harm if someone or something that is vulnerable is exposed to a hazard. In quantitative terms, hazard is defined by three parameters: a level of hazard (severity), its occurrence frequency, and location, for example, a fatal car crash (severity) in every month at a specific intersection. And risk is defined by four parameters: a probability, level of severity, time period, and location. For example, in health sciences, risk is defined as the likelihood (probability) of getting cancer (severity) if an average daily dose of a hazardous substance is taken over a 70-year lifeti
for an example that probably corresponds to Asker's map caption.
