<p>Some regions of mainland Portugal, especially the southern region, are exposed to considerable seismic hazard. There is also a wide variety of building typologies, including structures of masonry and wood, masonry and reinforced concrete and reinforced concrete built in different times and with different degrees of seismic vulnerability. In the last few years, there was a significant growth in the number of building rehabilitation projects in historic centres of Portuguese cities. Some of these interventions are founded on well-conceived projects which take into account the date of construction and the original construction methods and materials, however, there are somewhat legal procedures which seriously undermine the safety of renovated buildings decreasing their seismic performance. This paper illustrates some provisions on traditional building techniques that ensure a better performance of buildings during an earthquake. It also points out and illustrates some of the major mistakes in building rehabilitation that contribute to increase their seismic vulnerability.</p>

Probabilistic Seismic Hazard

Penelitian mengenai daerah rawan gempa bumi ini menggunakan Metode Probabilistic Seismic Hazard Analysis (PSHA) di Provinsi Sulawesi Barat, dengan tujuan untuk memetakan tingkat kerawanan bahaya gempa bumi di Kabupaten Mamasa. Penelitian ini menggunakan data kejadian gempa bumi di Pulau Sulawesi dan sekitarnya dari tahun 1900 – 2015. Hasil pengolahan PSHA menggunakan Software Ez-Frisk 7.52 yang menghasilkan nilai hazard di batuan dasar pada kondisi PGA (T = 0,0 sekon), dengan periode ulang 500 tahun dan 2500 tahun berkisar antara (149,54 – 439,45) gal dan (287,18 – 762,81) gal. Nilai hazard di batuan dasar dengan kondisi spektra T = 0,2 sekon untuk periode ulang 500 tahun dan 2500 tahun adalah (307,04 – 1010,90) gal dan (569,48 – 1849,78) gal. Nilai hazard di batuan dasar dengan kondisi spektra T = 1,0 sekon untuk periode ulang 500 tahun dan 2500 tahun diperoleh nilai (118,01 – 265,75) gal dan (223,74 – 510,92) gal. Berdasarkan analisis PSHA, nilai PGA di Provinsi Sulawesi Barat dominan dipengaruhi oleh sumber gempa sesar.
