Seismica

Seismica v1.5.0

Realism

• Radar intensity maps now account for hypocentre depth — a deep quake no longer displays surface intensities several levels higher than what is actually felt
• All equipment now reports the same estimate for a given event. Previously a seismograph, radar and EEW station could each show a different magnitude for the same quake
• Reworked intensity attenuation: the highest bands (XI, XII) now cover a visible area around the epicentre, while weak shaking spreads much further out than before
• Low intensities are finally noticeable — MMI I gives a brief 0.7s tremor, MMI II about 1.5s, MMI III a light shake
• Maximum hypocentre depth raised to 100

Destruction

• Collapse thresholds are now set per material: cobblestone VII, stone / brick VIII, concrete IX, iron and reinforced concrete X. Mixed builds average out between them
• Buildings behind the wavefront are re-checked for the duration of the shaking instead of getting a single brief chance, so structures near the epicentre no longer survive intensities that should level them
• Far more probe points per pass, plus a grid sweep at high intensity, so narrow towers and thin walls are no longer missed entirely

Interface

• MMI colour key down the side of the Advanced Radar scope
• Facing direction indicator on all radar and fault map screens
• The terrain map now scales with the radar's zoom level
• Radar and fault map rendering rewritten — opening a scope no longer causes heavy frame drops
