<dt>Description</dt>
<dd>A cosmic-ray induced nuclear event detected in the emulsion chamber is described. The event consists of 217 shower cores with &lt;math&gt;\Sigma E \gamma\,\!&lt;/math&gt; = 1,275 TeV. In log scale, energy and particles are emitted most densely at the small lateral distance corresponding to 0.5 mm; 77 % of the total energy and 61% of the total multiplicity are inside the radius of 0.65 cm. The shower cores in the central region show exponential-type energy distribution and non-isotropic azimuthal distribution. This event indicates a possibility that phenomena of large transverse momentum could happen to produce a strong concentration of energy and particles in the very forward direction.</dd>
