What are the probelms of managing an inhabited environment prone to tectonic hazards?

Question

Please provide examples when you can.

Answer 1

I googled "tectonic hazards" (earthquakes & volcanoes) to see what I could find. This is from The British National Space Center:

"Earthquakes and volcanoes can be devastating. The eruption of volcanoes in populated areas causes great hardship for local people and disrupts communications and infrastructure.
The San Francisco Bay Area of California is particularly at risk from earthquakes because it lies on a plate boundary called the San Andreas Fault. In 1989, an earthquake measuring 6.9 on the Richter Scale coincided with the afternoon rush hour and brought chaos to the city.
We associate many features with plate boundaries, including fold mountains, active volcanoes and fault zones. Long lines of plate boundaries occur beneath the oceans with features related to the plate movements. These include volcanic peaks (sea mounts), mid-ocean ridges and deep ocean trenches. Tectonic hazards such as earthquakes and active volcanoes occur mainly at the plate edges.
In populated areas, these hazards can lead to devastation and loss of life. It is very difficult to predict when these events will take place. In addition, secondary events such as mudslides or tidal waves, resulting directly from the initial hazard, can wreak their own havoc and cause more damage."

On a personal level, I have lived in California, Mexico and Japan and experienced large earthquakes in all 3 places. The last major earthquake I experienced directly was the Great Hanshin Earthquake in Kobe, Japan in 1995. That 7.2 quake lasted 20 seconds (seemed like a lifetime!), killed 6000 people, started fires that raged for days, and caused about $100 billion in damage, including destroyed buildings, toppled highways and railway lines, and disruption to major pipelines.
See the Wiki link for more info and/or google "plate tectonics"
(again Wiki does a great job presenting difficult science well).

Answer 2

INHABITED ENVIRONMENT MAY HAVE FOLLOWING TECTONIC HAZARDS;

CONTINUOUS SUBSIDENCE AND AGGRESSION OF SEAS
SUCH AS POLDAR REGIONS OF NORTH WEST EUROPE

SQUEEZING OF GEOSYNCLINAL MATERIAL BETWEEN TWO PLATES AND EVER INCREASING SEISMIC ACTIVITIES

VOLCANIC ERUPTIONS AND EMMISSION OF TOXIC GASES

CONTINUOUS DAMAGE TO INFRASTRUCTURE

USE OF SUBSTANTIAL BUDGET ON DISASTER MITIGATION
