Near-Earth asteroids and meteoroids constitute various levels of impact
danger to our planet. On the one end, billions of events associated with
small-sized meteoroids have resulted in trivial effects. On the other
end, the occurrences of large-sized asteroidal collisions that can cause
mass extinctions and may wipe out the modern human civilization are
extremely rare. In addition, large near-Earth asteroids are being
monitored constantly for accurate and precise predictions of potential
hazardous visits to our planet. However, small asteroids and large
meteoroids can still often go under the radar and cause bolide
explosions with potential of significant damage to communities on the
ground. To facilitate management of bolide hazard, a number of scholarly
works have been dedicated to estimation of frequencies of bolide events
from a global perspective for planetary defense and mitigation.
Nevertheless, few of the existing bolide frequency models were developed
for local hazard management. In this presentation, the author introduces
two recently developed frequency models for local management of bolide
hazard. The first one, called the Dome model, computes the expected
frequency of bolide explosions within a dome-shaped volume around a
location. The second one, called the Coffee Cup model, is for a
column-shaped volume above an area. Both models are based on empirical
calibrations with historical data on energy, latitude, altitude, and
frequency of bolide events. The modeling results indicate a linearly
decreasing trend of frequency of bolide events from south to north
latitudinally around the globe. The presented models can be applied to
any location or area on Earth, including the entire surface of the
planet.
