भूकम्पश्चाभवत्तत्र शताङ्गो भूगतो ऽभवत् दृष्ट्वा क्षोभमगाद्रुद्रः स्वयम्भूश्च पितामहः //

There an earthquake arose, and Śatāṅga sank down into the earth. Seeing that great turmoil, Rudra departed, together with the Self-born Grandfather, Brahmā.
It presents pralaya-like omens: an earthquake and a being (Śatāṅga) swallowed by the earth, prompting even major deities (Rudra and Brahmā) to withdraw—signaling escalating cosmic instability.
Indirectly, it frames calamities as dharmic warning-signs: rulers and householders should respond to widespread portents with restraint, protection of people, and appropriate rites rather than panic—an ethical posture consistent with Purāṇic governance ideals.
Architecturally, an earthquake is a classic inauspicious sign affecting land and foundations; ritually, such upheaval typically calls for śānti (appeasement) rites to stabilize the realm and sacred spaces—useful context for readers seeking Matsya Purana Vastu Shastra tips.
