1920年12月16日发生在宁夏海原8．5级的大地震又称“环球大震”,其地震波绕地球传播两圈,地震波将哨马营的这棵古柳劈成两半,86年过去了,古柳依然存活在这片干旱的土地上,劈成两半的古柳犹如展开的手掌向着苍天诉说着什么……海原县委、县政府正在积极筹措将这棵“震柳”作为地震文化中的遗产开发和保护起来。据当代科学家计算,1920年海原大地震显示的自然之力,震波能量为3．55*14尔格,相当于2.2亿吨炸药能量,相当于唐山地震11倍的能量。
December 16, 1920 occurred in Ninghai Haiyuan 8.5 magnitude earthquake, also known as “Global Earthquake”, the seismic wave spread around the Earth twice, the seismic wave will be sentinel Ma Guixian ancient will split in half, 86 years In the past, the ancient willow still survives on this arid land. The ancient willow split into two halves is like the palm of one hand in the sky. What is said ... Haiyuan county party committee and county government are actively raising this “Zhen Liu” as an earthquake Heritage in culture is developed and protected. According to contemporary scientists, the natural force shown by the 1920 Haiyuan earthquake shows that the seismic energy is 3.55 * 14 erg, equivalent to 220 million tons of explosive energy, equivalent to 11 times the energy of the Tangshan earthquake.
