TL;DR: A major earthquake occurred at 20:33 UTC (3:33 pm local time) near the coast of southern Peru, 175 km west of Ocona and 595 km southeast of Lima.
Abstract: On 23 June 2001 a major earthquake occurred at 20:33 UTC (3:33 pm local time) near the coast of southern Peru, 175 km west of Arequipa and 595 km southeast of Lima. The earthquake ruptured a portion of the plate boundary between the Pacific and Nazca Plates and produced ground shaking that was felt in much of southern Peru and northern Chile. It killed at least 57 people and destroyed or damaged more than 60,000 homes, affecting more than 223,000 people (USAID, 2001). The earthquake produced a tsunami that left an additional 24 people dead and 62 missing in the Camana area (INDEC, 2001). This report summarizes the results of the first International Tsunami Survey Team (ITST) that surveyed the tsunami impacts two weeks after the earthquake and discusses the seismological characteristics of the earthquake that pertains to the tsunami.
The PDE location of the mainshock epicenter (USGS) is 16.26°S 73.64°W, about 60 km northwest of Ocona in the Department of Arequipa, Peru; depth is unconstrained and fixed at 33 km. Figure 1A shows the epicenter and the extent of aftershocks over a 30-day window following the mainshock. The aftershock distribution suggests a 300-km-long by 125-km-wide rupture, extending southeast from the epicenter to the vicinity of Ilo, about 150 km north of the Chilean border.
Conventional magnitudes were mb 6.7 and Ms 8.2; a mantle magnitude Mm 8.6 (Okal and Talandier, 1989) was measured at Papeete (D. Reymond, pers. comm.), corresponding to a seismic moment M = 4 × 1028 dyn-cm. Other estimates of the seismic moment, given in Figure 2, range from 1.2 to 4.9 × 1028 dyn-cm. Harvard's final solution (4.67 × 1028 dyn-cm) gives the event the largest moment in the CMT catalog, making this the largest earthquake since …

TL;DR: In this paper, the authors analyzed the damage probability of building structures due to tsunami impact in the Callao region of Peru and found that approximately 30% of submerged building may be washed away by tsunami inundation in the probabilistic hazard scenario and approximately 60% in the historical hazard scenario.
Abstract: The implementation of adequate urban development and measures systems against tsunami impact in coastal communities is improved by understanding damage probability among building structures. Within the framework of the project Enhancement of Earthquake and Tsunami Disaster Mitigation Technology in Peru (JST-JICA SATREPS), the authors analyze the damage probability of building structures due to tsunami impact in the Callao region of Peru. Two different tsunami hazard scenarios are assumed in assessing building damage probability. The first tsunami scenario represents the worse-case scenario of tsunami inundation that calculates the envelop of maximum inundation depth and flow velocity values from 12 probabilistic megathrust earthquake scenarios for central Peru. The second tsunami scenario corresponds to a historical tsunami event in this region. We apply a methodology for evaluating different levels of building damage by combining tsunami numerical results and tsunami fragility functions. Damage probability was analyzed in detail on a single building scale in the La Punta district. For the rest of Callao region, analysis was performed on a block-unit scale. Our results suggest that approximately 30% of submerged building may be washed away by tsunami inundation in the probabilistic hazard scenario and approximately 60% in the historical hazard scenario.

TL;DR: The immune response to the whole cell component of the vaccine was reduced by high pre-existing vibriocidal antibody titres, and administration of 2 doses of WC/rBS vaccine concomitantly with natural V. cholerae O1 infection enhanced the serum anti-cholera toxin response.
Abstract: A 'double-blind', randomized, placebo controlled study of an oral inactivated whole cell plus recombinant B subunit (WC/rBS) cholera vaccine was conducted during February-March 1992 in Peru in 346 military recruits, 307 (89%) of whom received 2 oral doses of vaccine or Escherichia coli K12 placebo, 2 weeks apart. Paired serum samples were obtained from 155 (50%) of the recipients of 2 doses. An epidemic of cholera took place between doses. No difference in cholera attack rates was detected between vaccine and placebo recipients after one dose (8% versus 14%). Seroconversion (4-fold or higher increase in vibriocidal antibody titres) was detected in 90% and 80% of vaccine and placebo recipients, respectively, with low pre-existing vibriocidal titres (< 0.01). The anti-cholera toxin seroconversion rate among those with low pre-existing titres was higher in vaccinated subjects (97%) than in placebo recipients (68%) (P < 0.01). Administration of 2 doses of WC/rBS vaccine concomitantly with natural V. cholerae O1 infection enhanced the serum anti-cholera toxin response. The immune response to the whole cell component of the vaccine was reduced by high pre-existing vibriocidal antibody titres.
